Ooo

#

Lets see it 😄

digital rose Dec 29, 2018, 7:56 PM

#

Ok, well you only have to modify and update within the select event:

#

    """ Units in Combobox during ChangeEvent """
    def convert(self, event):
        """ Automatic Unit Conversion """
        print("convert!")
        # Point of Impact
        trajectory = ProjectileMotion.Vacuum(np.float64(self.entry_velocity.get()), np.float64(self.entry_angle.get()), np.float64(self.entry_height.get()))
        if self.scroll_point_of_impact.get() in UNIT_DICTIONARY:
            # test prints
            print("old", UNIT_DICTIONARY[self.previous_unit])
            print("new", UNIT_DICTIONARY[self.scroll_point_of_impact.get()])

            width = np.float64(u.convert_to(trajectory.point_of_impact()[0]*meter, UNIT_DICTIONARY[self.scroll_point_of_impact.get()]).as_ordered_factors()[0])
            height =  np.float64(u.convert_to(trajectory.point_of_impact()[1]*meter, UNIT_DICTIONARY[self.scroll_point_of_impact.get()]).as_ordered_factors()[0])

            Application.set_entry(self.entry_point_of_impact, f"({np.round(width, decimals=PRECISION)} | {np.round(height, decimals=PRECISION)})")

            self.previous_unit = self.scroll_point_of_impact.get()

#

this looks because complicated there is much more

#

but only the last line is important

gentle rain Dec 29, 2018, 7:58 PM

#

ohhhh

#

Very cool ngl

digital rose Dec 29, 2018, 7:59 PM

#

so yeah, after you're done with the main function, don't forget to update self.previous_unit by setting it to a new value

gentle rain Dec 29, 2018, 8:00 PM

#

👌

#

Much simpler than my solution haha

digital rose Dec 29, 2018, 8:02 PM

#

if the problem is easy to explain, than the solution shouldn't be complicated either
that's not true every time but it works out most often than not exactly like that

i am making a minesweeper

#

and i want to collapse a button which is pressed

#

i made a fucntion

def CollapseButton():
    gridButton.config(relief=SUNKEN)

#

but i cant specify the exact button

#

it just collapses the bottom right one

thorny spruce Dec 30, 2018, 3:26 PM

#

What do you mean collapse?

past palm Dec 30, 2018, 3:26 PM

#

in this case just change a relief

#

but i cant specify which button

#

it just collapses bottom right one

thorny spruce Dec 30, 2018, 3:27 PM

#

I'm going to assume you are dynamically creating your buttons

past palm Dec 30, 2018, 3:28 PM

#

for loop within for loop

#

you can take a look in my friends and my repo

thorny spruce Dec 30, 2018, 3:28 PM

#

Ah I see you have a dictionary for them

past palm Dec 30, 2018, 3:28 PM

#

we thought of that idea but cant realise it

thorny spruce Dec 30, 2018, 3:29 PM

#

So the issue is that when the CollapseButton functions gets called your gridButton will always be the last one that was created

past palm Dec 30, 2018, 3:30 PM

#

yeah i see that by the fact only bottom right button collapses

thorny spruce Dec 30, 2018, 3:30 PM

#

What you'll want to do is maintain a reference and make each CollapseButton unique to each button

past palm Dec 30, 2018, 3:31 PM

#

and how do i do that

fervent sluice Dec 30, 2018, 3:31 PM

#

I am working on the project w/him

#

what would be our reference then?

thorny spruce Dec 30, 2018, 3:32 PM

#

Is there a reason all the buttonsDiff1 functions are the same?

past palm Dec 30, 2018, 3:34 PM

#

i just wanted to change ranges in for loops

#

but he wanted 3 functions for each difficulty

#

how would you solve that problem

thorny spruce Dec 30, 2018, 3:36 PM

#

I see, well what I would suggest is first you don't need to generate a string for the key

gridButton = Button(frame, relief=RAISED,command=CollapseButton)
gridButton.place(...)
buttonsDict[(row, column)] = gridButton

#

Now are you familiar with lambda functions?

past palm Dec 30, 2018, 3:36 PM

#

sorta

thorny spruce Dec 30, 2018, 3:37 PM

#

Well what we can do is change the CollapseButton to accept a row, column and use that to get the active button

#

def CollapseButton(row, column):
    buttonsDict[(row, column)].config(relief=SUNKEN)```

past palm Dec 30, 2018, 3:38 PM

#

and we also need to change command in button arguments?

thorny spruce Dec 30, 2018, 3:38 PM

#

What we then have to do is change the command part to account for this

past palm Dec 30, 2018, 3:38 PM

#

yeah

thorny spruce Dec 30, 2018, 3:39 PM

#

Which looks like

gridButton = Button(frame, relief=RAISED,command=lambda r=row,c=column: CollapseButton(r, c))```

#

Do you understand what this is doing lambda r=row,c=column?

past palm Dec 30, 2018, 3:40 PM

#

making it global?

fervent sluice Dec 30, 2018, 3:40 PM

#

well that was the problem, we didnt know how to pass row and column

thorny spruce Dec 30, 2018, 3:40 PM

#

Not quite, how about this

def func(x=0, y=1): ...```

#

What are x and y?

past palm Dec 30, 2018, 3:42 PM

#

arguments

thorny spruce Dec 30, 2018, 3:43 PM

#

Specifically keyword arguments. If they are unspecified when the function is called they will default to the given value.

func() # x = 0, y = 1
func(5) # x = 5, y = 1
func(5, 6) # x = 5, y = 6```

#

We are taking advantage of this in the lambda function

past palm Dec 30, 2018, 3:45 PM

#

and lambda passes row and column into CollapseButton(row,column) ?

thorny spruce Dec 30, 2018, 3:45 PM

#

lambda r=row,c=column: CollapseButton(r, c)

Because no arguments are provided when the lambda function is called r and c will default to what row and column were at the time the lambda was created

past palm Dec 30, 2018, 3:45 PM

#

hmm

#

default?

#

and those rows and columns get into dictionary

#

am i right?

thorny spruce Dec 30, 2018, 3:47 PM

#

Yea

#

A cleaner way than using the lambda is to use functools.partial

from functools import partial
gridButton = Button(frame, relief=RAISED,command=partial(CollapseButton, row, column))

#

how do i solve this

thorny spruce Dec 31, 2018, 1:37 PM

#

So with .bind what happens is it will give you an event object when the bound event occurs

#

You need to do

#

buttonsDict[(row, column)].bind('<Button-3>',
                                            lambda event, row=row, column=column: flag(row, column))

#

Have the lambda take the event and just not pass it in, or modify your flag function to use the event if you need it

past palm Dec 31, 2018, 1:39 PM

#

and event needs to be last argument of flag function?

#

or first

#

oh i figured it out

#

thank you

#

but im curious

#

i dont take an event in flag arguments, but however it recognizes the right button

thorny spruce Dec 31, 2018, 1:43 PM

#

You do .bind('<Button-3>', ...)

#

So whenever button 3 is pressed for this widget it fires the event

#

Calling any function bound to this event passing it an event object

Depends on your structure and approach really

Maybe another dictionary tracking the state of each button, or switch it to an object instead. It's up to you at this point

How do you link a variable between the main .py file and the .kv file? I've tried app.variable, className.variable, MainApp.variable...I'm not understanding what the SO posts are referring to exactly when they use all these terms. Here's what I've got :

class MainWindow(FloatLayout):
    # All the init stuff
    self.my_variable = ""

class MainApp(App):
    def build(self):
        return MainWindow()

if __name__ == "__main__":
    myWindow = MainApp()
    myWindow.run()

What would I use in my .kv file in this case to access self.my_variable from the MainWindow class?

thorny lichen Dec 31, 2018, 10:53 PM

#

I've also tried making a variable in my .kv file like this, but still not working

<MainWindow>:
    my_variable: my_variable_kv

    <Label>:
        id: my_variable_kv

This isn't working either.

thorny lichen Dec 31, 2018, 11:09 PM

#

And also this:

<MainWindow>:
    <Label>:
        text: root.my_variable

This returns an error saying that MainWindow has no attribute "my_variable"

#

I also tried this:

class MainWindow(FloatLayout):
    # Init stuff
    self.my_variable = StringProperty()

class MainApp(App):
    def build(self):
        return MainWindow()
myWindow = MainWindow()
myWindow.run()

crude sparrow Jan 2, 2019, 10:52 PM

#

@fervent sluice Perhaps set the image again onto the button? When you set a button to disabled, tkinter messes with the colors to show it being "grayed out". Perhaps that's also modifying your image.

fervent sluice Jan 2, 2019, 10:58 PM

hello 👋
this question has been asked everywhere since 2010, but I didn't find a proper way to scroll the content of a window in Curses, without moving the border
https://media.discordapp.net/attachments/278257082237714432/530136106935517204/unknown.png?width=1248&height=663

I would like to be able to scroll up and forth (with the limits of the actual messages) in the history of the "chat", the overflow in both ways just not being shown.
I've seen about window.scrollok(True) which doesn't raise errors on overflow, and using a pad to only show a part of it, but I still do not get how to preserve the border (which doesn't actually have to be one, it may be a curses.textpad.rectangle)

In fact It seems I can only show one window at a time. I think it's because they all cover the whole screen but I don't know why.

hollow aspen Jan 3, 2019, 12:43 PM

In tkinter you can set window size with window.geometry('widthxheight') where you replace width and height by their respective values

I would like for the file path to show up in this little text box when I select a file using the 'browse' button

Right now, when I select a file there's no feedback that shows which one I selected, or even if I selected one at qll

You could use the filedialogs

    file = filedialog.askopenfilename()
    res = filename
btn = Button(window, text="Browse", command=clicked)```

#

#

There we go

#

This makes it so I can browse for a file when I press the button

#

But when I select a file, the browser window closes and I'm left with no feedback as to what I selected

thorny spruce Jan 3, 2019, 1:01 PM

#

file is the selected filename, this is just a string. You'll want to insert this string into your entry widget

hollow aspen Jan 3, 2019, 1:02 PM

#

How do I go about that?

Exactly that. You have your entry widget, delete any content and then insert the filename into it

hollow aspen Jan 3, 2019, 1:06 PM

#

You mean like this?

📎 3-01-2019_14-06-09.png

#

I just manually entered that

thorny spruce Jan 3, 2019, 1:08 PM

#

Can you provide more of your code?

hollow aspen Jan 3, 2019, 1:09 PM

#

Sure, I'll post the whole thing

#

from tkinter import *

from tkinter import filedialog
 
#Window geometry and title

window = Tk()
window.title("File splitter")
window.geometry('350x200')

#Functionality of 'Browse' button and text thingie

txt = Entry(window,width=45)
txt.grid(column=1, row=0)

def clicked():
    file = filedialog.askopenfilename()
btn = Button(window, text="Browse", command=clicked)
btn.grid(column=2, row=0)

window.mainloop()```

#

That's all of it

thorny spruce Jan 3, 2019, 1:11 PM

#

Okay so txt is your entry widget

#

Inside your clicked function you want to delete everything from txt

#

After prompting for the filename

hollow aspen Jan 3, 2019, 1:15 PM

#

I'm really sorry, I don't understand what you mean

#

Could you give me an example?

thorny spruce Jan 3, 2019, 1:19 PM

#

http://effbot.org/tkinterbook/entry.htm

#

I'd suggest reading up on what you can do with each widget

hollow aspen Jan 3, 2019, 1:20 PM

#

I'll have a look, thanks

thorny spruce Jan 3, 2019, 1:21 PM

#

That site has some code examples, they are just in Python 2. This one is a bit more comprehensive http://infohost.nmt.edu/tcc/help/pubs/tkinter/web/entry.html

crude sparrow Jan 3, 2019, 1:48 PM

#

In order to "fill in" the input field, you'll want to use a StringVar. When you create the Entry widget pass in your StringVar by setting the parameter textvariable. Then when you wan to change it, you change the StringVar

thorny spruce Jan 3, 2019, 1:51 PM

#

You don't need a textvariable for any widget other than a Listbox

crude sparrow Jan 3, 2019, 1:53 PM

#

I stand corrected?

thorny spruce Jan 3, 2019, 1:53 PM

import tkinter as tk

    if filename:

Just telling you how I've done it

thorny spruce Jan 3, 2019, 1:56 PM

#

That's understandable, I just don't see the merit in creating another object

crude sparrow Jan 3, 2019, 1:59 PM

#

It's a documented technique on the page you posted already

#

http://effbot.org/tkinterbook/entry.htm

thorny spruce Jan 3, 2019, 2:00 PM

#

They aren't the best usage examples and they're pretty old as well. It's from Python 2

#

That's also mentioned as another way you can do it, not as a better way. It still just comes down to preference though so to each their own.

crude sparrow Jan 3, 2019, 2:05 PM

#

http://infohost.nmt.edu/tcc/help/pubs/tkinter/web/control-variables.html discusses using variables for other widgets as well

#

"Normally the text displayed in an Entry widget is linked to a control variable. "

#

Radio buttons need them as well

hey i have an issue with tkinter, i am only two days into learning it forgive my probably ignorant mistake

#

i am trying to get a line of text and then a table underneath it in a window

#

i am using a grif

#

grid*

#

and i want to know if there is a way to get one label to stretch over two columns

#

📎 Capture.PNG

#

here u can see that the first column is really wide

#

if the top label could go in both columns it would be nice and neat

#

how could i do this here is my code:

@pearl birch You can span multiple columns by using columnspan as discussed here http://www.effbot.org/tkinterbook/grid.htm

aksing this question again because I'm really desperate xD
So I have this tkinter application I haven been working on the last couple of weeks, and inside my Application class which initialize the GUI I am only using the grid geometry manager.

But in my main() function when I execute

if __name__ == '__main__':
    gui = Application()
    # gui.pack()
    gui.mainloop()

the GUI only shows up not as a blank canvas when I uncomment the gui.pack() line. I heard that there are good reasons not to mix grid() and pack(), and I didn't use pack() anywhere else in my code except on this one line because; sadly that's the only way I can get my application to run and I don't have to clue which could have caused this. In my barebones.py application this doesn't happen so I am bit worried that there's something inherently wrong with my project... in fact, it's the complete opposite on my minimalistic example code: using gui.pack() would produce the same error as in my main application.

here's the full code: https://paste.pydis.com/yejaforezu.py
Note that only def ui(self) is in charge of initializing the tkinter widgets, the rest seems to be unrelated to the problem since it has nothing to do with it. In ui(self) I really only added a lot of labels, entry and combobox widgets (as well as label frames and buttons) which I positioned with grid() but this can't be the root of the problem, right? So what else could have gone wrong which I should be looking for?

digital rose Jan 3, 2019, 11:40 PM

#

Update:

Here's the same application with much less could. It still produces the same error:

#!/usr/bin/env python
# -*- coding: utf-8 -*-

import tkinter as tk
import tkinter.font as font
from tkinter import ttk

class Application(tk.Frame):
    def __init__(self, master=None):
        tk.Frame.__init__(self, master)
        self.master.title("Test Application")
        self.master.resizable(0,0)
        self.ui()

    def ui(self):
            system = font.Font(family="System", size=12)

            # Matplotlib Figures
            labelmatplotlib = tk.Label(self, text="matplotlib figure", bg="yellow", relief=tk.RIDGE, bd=2)
            labelmatplotlib.grid(row=0, column=0, padx=2, pady=2)

            # Parameter Groupbox

if __name__ == '__main__':
    figure = Application()
    figure.pack()
    figure.mainloop()

thorny spruce Jan 4, 2019, 1:29 AM

#

I ran your code snippet and it does not produce an error @digital rose

#

You can mix grid and pack just not for for child widgets of the same direct parent. For example we have a Frame and 2 Labels,

f = tk.Frame(...)
l1 = tk.Label(f, ..)
l2 = tk.Label(f, ..)

Now it doesn't matter if you use .pack or .grid, what matters here is that because both labels share the same direct parent they must both be .pack or both .grid you can't have one label with .pack and the other with .grid

digital rose Jan 4, 2019, 3:23 AM

#

@thorny spruce it produces the error when you remove the figure.pack() line below main: but that shouldn’t be the case because mainloop() alone should also be able to run the app?

thorny spruce Jan 4, 2019, 3:25 AM

#

So if I comment out figure.pack() I still don't get an error. Can you post the full error message you are getting?

#

I'm still referring to the code snippet you posted

digital rose Jan 4, 2019, 3:28 AM

#

So am I; I’m actually writing this from my cell phone so I don’t have the exact error log here right now but it had something to do with grid/pack being in conflict if i recall right. When I’m back home I can give you more details but this will take some time

thorny spruce Jan 4, 2019, 3:29 AM

#

That's fine, just post it when you can

digital rose Jan 4, 2019, 3:31 AM

#

Okay! 😉

digital rose Jan 4, 2019, 11:54 AM

#

@thorny spruce in this example the tkinter app remains blank with gui.pack()

📎 7caf5c3a1e43a925.PNG

thorny spruce Jan 4, 2019, 11:56 AM

#

That's not an error. Widgets don't get rendered unless you pack, grid or place them

#

Even if you pack the child widgets you still need to pack the parent

digital rose Jan 4, 2019, 11:57 AM

#

ok, but I have a very similar application which kinda does produce error I'll show you in a moment

#

the code:

#

#!/usr/bin/env python
# -*- coding: utf-8 -*-

    def __init__(self, master=None):
        tk.Frame.__init__(self, master)

        self.master.geometry("600x500")
        self.ui()

    def ui(self):
            self.label_plot = tk.Label(text="Labels!", relief=tk.RIDGE, width=20)

#

that's why I am confused!

#

because the error disappears when you don't pack this code snippet

thorny spruce Jan 4, 2019, 12:03 PM

#

You didn't specify self for any of the widgets in ui, if a parent widget is not provided it will default to None, if None is given then the parent widget becomes the root widget

#

Because of this the parent widget for gui is the root window and you've use .pack(), then in ui the parent is the root window and you've use .grid

-reposting because it's been moved up, removed old post-
Hello! (PyQt5)
This is my code: https://paste.pydis.com/inecezaset.py
What I'm having struggles with is creating a second window when the button ("armBtn")/(label: "MyTools").
The window isn't "active" or available until the first window is closed. I believe this has to do with them both being "QMainWindow"'s.
(Setting variables to None in main code to keep the window alive after the button is clicked (not cleaned by garbage collector).

Does anyone know how I can solve my issue? >_< (also I've tried QDialog but not managed to get it to work)
Thanks. 😃

Hello again!
How can I get rid of this warning / solve it? It pops up in a console window when I launch my application.

   QT_AUTO_SCREEN_SCALE_FACTOR to enable platform plugin controlled per-screen factors.
   QT_SCREEN_SCALE_FACTORS to set per-screen factors.

PyQt 5 and 4k screen

I'm trying to migrate an existing PyQt5 app to high-dpi for window 10.

The documentation of Qt5 itself speak about high-dpi scaling here:

Ok so, os.environ["QT_SCALE_FACTOR"] = "1"

#

Ugh, it still opens an empty console...

crude sparrow Jan 5, 2019, 2:37 PM

#

@modest linden How are you launching your program? If you run it via pythonw then you won't get a console window.

modest linden Jan 5, 2019, 3:16 PM

#

Compiling it with PyInstaller and running it as .exe also launches a console >_<

crude sparrow Jan 5, 2019, 8:28 PM

#

@modest linden I use the flags -wF with PyInstaller which will produce an EXE that doesn't show a console.

modest linden Jan 5, 2019, 10:45 PM

#

😮 thx ❤ will try that

#

❤ worked

#

hmm does not seem to work for Mac though, rather 2 files are created, a unix executable and a .app, the unix one is basically the same as compiling without -wF, and the .app launches and closes itself, nothing happens

#

                        Windows and Mac OS X: do not provide a console window
                        for standard i/o. On Mac OS X this also triggers
                        building an OS X .app bundle. This option is ignored
                        in *NIX systems.```

#

Well... it still shows the console on mac <_< thats a shame

#

and the .app does nothing

Sorry to hear you've got a Mac

#

😩

#

I dunno why, but it seems like Macs struggle with Python GUIs. It's so backwards

#

Someone recently shared info on how to create an App file for PySimpleGUI.... maybe it'll work for you on this

#

It's for tkinter though, so you'll have to change a couple of things.

(PyQt5)
I don't have a problem with my code, I just can't find how to manage something.

    self.colorText = 0
    self.colorBg = 0
    self.pal = QPalette()
    pal2 = QPalette()
    self.pal.setColor(QPalette.WindowText, Qt.black)
    self.pal.setBrush(QPalette.Window, Qt.white)
    self.dbWindow.setPalette(self.pal)

def textChange(self):

    if self.colorText == 0:
        self.colorText = 1
        self.pal.setColor(QPalette.WindowText, Qt.blue)
    elif self.colorText == 1:
        self.colorText = 2
        self.pal.setColor(QPalette.WindowText, Qt.red)
    elif self.colorText == 2:
        self.colorText = 0
        self.pal.setColor(QPalette.WindowText, Qt.black)
    self.dbWindow.setPalette(self.pal)

def bgChange(self):

    if self.colorBg == 0:
        self.colorBg = 1
        self.pal.setBrush(QPalette.Window, Qt.lightGray)
    elif self.colorBg ==1:
        self.colorBg = 0
        self.pal.setBrush(QPalette.Window, Qt.white)
    self.dbWindow.setPalette(self.pal)```

Basically, I have two buttons that change either the text's or the bg's color respectively when clicked. What I want, however, is for the bg (the one controlled with the Brush class) to either not have a color or be light gray. Since I can't find a way to do this, I use white color as a filler.

So how can I simply turn a color on/off instead or relying to colors?

@rocky flint i believe what you're looking for might be setData(0, QtCore.Qt.BackgroundRole, None) to reset the bg color

Hey, I am having some difficulty in PyQt5 in regards to MdiArea subwindows. Attempting to add (or open/close) subwindows via file menu buttons.

Is there an existing function I should be using because the

self.ui.mdiArea.addSunwindow()

Doesn't appear to work outside of the initial QMainWindow set up.

Thanks for any help.

past palm Jan 8, 2019, 3:56 PM

#

why does everyone use pyqt instead of tkinter

sullen thunder Jan 8, 2019, 4:08 PM

#

I think like anything else it's a pick what you think will work best for your objectives. Also, it may have to do with PyQt building off Qt.

wind birch Jan 8, 2019, 4:13 PM

#

And QtCreator is a big help too; I imagine.

timid elbow Jan 8, 2019, 6:22 PM

#

@sullen thunder have you considered declaring the subwindow in the initial QMainWindow setup but using .hide() to make it not visible and and .show() when you're ready to have it appear?

sullen thunder Jan 8, 2019, 6:26 PM

#

@timid elbow I think I may have tested it this morning. However, it is always worth a second attempt with fresh eyes.

I want to say

self.ui.subwindow.hide() did not work, however I may have tried self.ui.mdiArea.subwindow.hide().

timid elbow Jan 8, 2019, 7:41 PM

#

I've been able to .hide() groupboxes, buttons, labels, and lineEdits, tree/tableViews. However, it didn't work when I tried to .hide() a layout. I haven't worked with subwindows and I'm still learning PyQt but I thought I might throw it out there as an idea.

sullen thunder Jan 9, 2019, 3:19 AM

#

@timid elbow I just attempted the .hide(). It doesn't appear to work at all.

The code

Self.ui.mdiArea.closeActiveSubWindow() will close an active window. However, I think it deletes it.

There may be something regarding Parent Child with the mdiArea but I can't seem to really locate much information regarding this. All I know is it appears possible just missing something

@sullen thunder I took a look at the docs so I'd have a better idea of the specifics of what you're looking at. Per your original question I don't see anything here http://doc.qt.io/qt-5/qmdiarea.html#addSubWindow that would prevent you from adding a subwindow via a menu action. There is some info about a flag you can set such that when close is called it does not delete the subwindow. Based on what I see here http://doc.qt.io/qt-5/qmdisubwindow-members.html there are QMdiSubWindow.show() and .hide() members. Did you remember to make an instance of QWidget or QMdiSubWindow to pass to self.ui.midArea.addSubWindow(mynewsubwindow)?

sullen thunder Jan 9, 2019, 6:16 PM

#

@@timid elbow I have been combing through some of the same documentation, and I am wondering some of the same thoughts.

The answer your question about QWidget or QMdiSubWindow. I believe your referring to my imports.

In the main doc (not the QDesigner converted file.) I do not import QMdiArea, or QMdiSubWindow from the PyQt5.QtWidgets module.

That may be worth an initial exploration that could explain why the functionality isn't working. As outside of the def init I don't call on the GUI design code.

As for the flags. I was wondering if adding in the code

self.ui.mdiArea.addSubWindow( sunwindowX, QtWidgets.QDialog)

This might flag the subwindows as a dialog and allow me to use a .show() / .hide() function. Which I could just make the file menus toggle based.

#

@muted marsh what kind of output do you want to direct into a GUI?

I would imagine that if your running a console based code. The result should be saved to a .txt(or other file) that could be opened by the GUI.

But if your running them concurrently, I am unsure how to have one trigger another.

@sullen thunder Can I implete the things I make in pyqt designer into my program that I have written>

muted marsh Jan 9, 2019, 6:23 PM

#

Yeah the big issue is im building something for non technical people and it requires command line output in real time rather than from a file.

cold urchin Jan 9, 2019, 6:23 PM

#

All my variable are in .txt files

sullen thunder Jan 9, 2019, 6:27 PM

#

@Marlin I am not 100% sure I know what you are asking. You can import/read information from a .txt file in PyQt program. Much like any other Python program. So .txt can be used inside/outside the PyQt gui. I believe this is referred to as front end backend but I am not exactly well versed in that.

Keep in mind It will still depend how the file is written and how your program is reading it.

Speaking of PyQt

sullen thunder Jan 9, 2019, 6:29 PM

#

@muted marsh I haven't really explored that much. It sounds like you have a command line program that needs to be run and you would like to run it from a GUI.

Kind of like a pushbutton that opens and runs a script then shoots back the result? Or do they need to see the command line? That you might need to program in the ability to open command line and then visually run the script

atomic socket Jan 9, 2019, 6:30 PM

#

Gonna be working on a project I want to use Qt in, it's going to be open source, but not for financial gain. Would the GPL have any impact on that specifically?

#

I know I've wrestled between PyQt and PySide due to licensing in the past, but since I won't be charging for anything I don't think it'll be a problem.

muted marsh Jan 9, 2019, 6:31 PM

#

Yeah Kind of a like a push button that opens , runs the bash script. Right now I have a seperate terminal window that things are output to. Ideally I wanted to run that output in the same window instead of having two windows open

#

From my understanding , It's hard to do in the Tkinter because of how tinkter's Main loop works. I was wondering if another GUI library handled it diffrently.

sullen thunder Jan 9, 2019, 6:36 PM

#

@atomic socket I am not well versed in licensing for Qt and PyQt. It appears your fair game with Qt to share and use commercially. pyQt doesn't appear as lax. Sorry I can't be of more help there. If you have a finished product. Might not hurt to discuss with a professional to be safe.

atomic socket Jan 9, 2019, 6:38 PM

#

@sullen thunder No worries mate, thanks for the advice, I may discuss with a professional once I get further on into the project. okhandbutflipped

sullen thunder Jan 9, 2019, 6:41 PM

#

@muted marsh I admit I haven't really done anything with command line and GUI yet. sry I can't be of more help.

It does seems possible, I found an example on Google that appears to do what you are looking for.

It appears to import os

Then can get the stdout via
stdouterr = os.open4(cmd)[1].read()

Then sets a Qtextedit to display the output. That might be a start for you.

cold urchin Jan 9, 2019, 6:42 PM

#

@sullen thunder I use the the w+ and r functions when reading and writing files

#

with open("Example.txt","w+") as f:
     f.write(A variable)

#

This is normally how I write my txt grabs

sullen thunder Jan 9, 2019, 6:45 PM

#

@Marlin I see no reason you can't import variables from the .txt file.

cold urchin Jan 9, 2019, 6:45 PM

#

@sullen thunder Alright sounds great. Do you know any good resource that teaches me how to use pyqt?

sullen thunder Jan 9, 2019, 6:49 PM

#

@Marlin personally I used packtpub.com's book called Qt5 Python GUI Programming Cookbook.

Warning though: book is far from perfect. It does a good job walking you through most of the basics. It has typos and errors in the code examples.

If your patient and use Google then you can learn a lot. It took me three months to work through it. But I only did about an hour or two at a time.

hey all. I was explaining a problem ive been having #help-kiwi, I was advised to post it here. I have a tkinter project which is effectively two slideshows. The first loops between 10 images and serves as a gif background. the second loops all images in a file and displays them as a foreground image for about 1 second each. I load all of my background images into PhotoImage at the start of my loop, and load each new foreground image as it is needed. This works almost perfectly, save for when the foreground image is large enough to cause a delay in my background 'gif'. I am searching for a solution which allows me to iterate over any number of foreground images without slowing down the rate at which my background images refresh. Ive uploaded sample code here: https://stackoverflow.com/questions/53772520/tkinter-photoimage-halts-self-after

Stack Overflow

Tkinter Photoimage halts self.after()

My objective is to have a looping background image set, functioning exactly the way a .gif does, and on top of that, to have a slideshow of images loop concurrently with a delay of about 1 second.

#

As the name in the link suggests, I believe that the .after function which allows me to loop my background update is somehow halted when i load the foreground image into memory
Originally, when my foreground image list was under 200, i could use the tkinter PhotoImage function on the whole list and keep it in memory, which caused no delay. I was perfectly happy with this solution until my list of foreground images became too long to store in memory.
I then experimented with loading small lists of 5 images each into PhotoImage, which I hoped would function in the five seconds it took to loop the previous group of 5, but was met with an exaggerated version of the same problem I am having now.

#

In regards to the after function, the tkinter docs say "Tkinter only guarantees that the callback will not be called earlier than that; if the system is busy, the actual delay may be much longer." So i believe I am looking for a solution to either specify the callback time, or do some sort of multiprocess/threading operation to get around the system being busy part.

sullen thunder Jan 9, 2019, 9:40 PM

#

@timid elbow I think I figured it out. Will shameless admit, it was just throwing everything at the code until something stuck the way I wanted it to.

#

@timid elbow okay so, the way i ended up doing it is as follows.

I created 2 functions

def closeWindow(self):
self.ui.mdiArea.removeSubWindow(self.ui.subwindowX)
self.ui.mdiArea.closeActiveSubWindow()

def openWindow(self):
subWindow = self.ui.mdiArea.addSubWindow(self.ui.subwindowX)
subWindow.show()

This appears to work for me. I will need to conduct some furthur testing to make sure I can make the functions multipurpose to multiple different subwindows.

In short, the way I think this works is that the closeWindow() is outright deleting the subwindow and the openWindow is just inserting a new instance of it altogether.

yo ive made this in pyqt designer - i was wondering if anyone had an idea to create these duplicate boxes (which eventually will have the names etc changed) through like a class or something?

#

or would i have to manually write code for each one

#

sullen thunder Jan 10, 2019, 7:14 PM

#

@sage umbra I want to answer your question properly, so correct me if I missinterpt your goal.

In QDesigner you have generated an initial template and you would like to have the ability to generate these widgets with instance specific data.

You can definitely create a class with the widget design in it. Then a function that calls that class to place it on to the screen and populate it with the desired data.

Now, I haven't attempted to do anything like that yet. So maybe someone else can chime in with more detail.

sage umbra Jan 10, 2019, 7:16 PM

#

yea i got that far

#

shit its hard to explain

#

i wanna make a class with the name, pic and user type in so that everytime i need one of those on screen i can just use the class. any ideas on how i could do that

rocky flint Jan 10, 2019, 9:58 PM

Is there a way to make a QTextEdit widget not expand, but w/o shrinking the area around it or adding more widgets to make it "collapse" by force?
Using addStretch() does the trick, but it drags the widget at the bottom (even if I include Qt.AlignTop to my layout) and I want it to stay on top instead. The same happens when set its maximum height.

No. We do not provide one-on-one tutoring - you can hire someone locally if you really need that. We also prefer that questions are answered in a public channel as it means that everyone else present is able to learn from them. If you're working with code that you are unable to disclose for any reason, you should try to make your question more general and write a separate, small piece of code to illustrate your problem.

Ok so I am in my schools TSA (technology-student-association). My event is software development and I have some ok understanding of python. The goal of the event was to make a software that has an educational and or social value. So, I built basically a python script that uses input() statements and if statments that walks the user through a couple of challenges and so far its pretty good. Now, I need a way to display it other than just using command prompt and or MAC terminal. So I am trying to use Tkinter which I am unfamiliar with. Can someone here tell me how I can make a Tkinter window that can print, take user input, and based on that input produce output to that specific window? Thank you.

#

Reminder: The input/output stuff is done I just need help putting that into my tkinter

So what I'm trying to do is check for the memory location and if it matches, check it and then negate it

but when i use print(hex(id())) on the variable I notice that after negating the variable the memory location changes....

@marble viper you can't mix place and grid

#

and it's also unclear why your grid is so many rows and columns

#

also shouldn't mix root parent and frame parent like that

#

try this ```py
import tkinter as tk

def write_slogan():
print("Tkinter is easy to use!")

root = tk.Tk()
root.title('TechEvent Level-2')

#root.geometry("1080x1147")

frame = tk.Frame(root)
frame.pack()

labelEnterTeamID = tk.Label(frame, height=2,width=30,text="Please enter your Team ID:")
labelEnterTeamID.grid(row=0, column=0)

textBoxTeamID = tk.Text(frame,height=2,width=30)
textBoxTeamID.grid(row=1, column=0)

goButton = tk.Button(frame,
text="Go!",
command=write_slogan)
goButton.grid(row=2, column=0)
root.mainloop()

Anyone know how I would make a button disappear after 30 seconds

You need to use .after and pass the destroy method of the button

All of your code to add widgets is inside a function that you don't call

spare leaf Jan 15, 2019, 4:27 AM

#

what does that mean. sorry Im getting of new to this stuff

thorny spruce Jan 15, 2019, 4:28 AM

#

Okay so let's say when have a function

def func():
    print('Hello World!)

All this does is define a function, nothing inside the function is actually run until you tell it to

spare leaf Jan 15, 2019, 4:29 AM

#

ok

thorny spruce Jan 15, 2019, 4:29 AM

#

To run the function you need to call it by doing

func()

spare leaf Jan 15, 2019, 4:29 AM

#

ohhh righht right

thorny spruce Jan 15, 2019, 4:29 AM

#

Your case is the same, you have defined a function but it isn't used

spare leaf Jan 15, 2019, 4:30 AM

#

so every function that ive made ur saying needs to be called?

thorny spruce Jan 15, 2019, 4:31 AM

#

Pretty much, it's slightly different with tkinter though for buttons, when you add a function to a command for the button

my_button = tk.Button(master, command=func)```
You only provided the name, you do not call it like normal. This function will be called for you when the button is pressed

#

And not just buttons but anything that takes a command or if you use .bind, only provide the function name. When an event happens it will call the function for you

spare leaf Jan 15, 2019, 4:33 AM

#

but it still didnt work?

thorny spruce Jan 15, 2019, 4:33 AM

#

In what way didn't it work?

#

Well. I dont think thats the probelm since I havent binded anything to those windows

thorny spruce Jan 15, 2019, 4:37 AM

Well if I do the following

win()
window.mainloop()

I get the start button

spare leaf Jan 15, 2019, 4:52 AM

#

@thorny spruce sorry to bother you again

#

but for some reason now when I click the start button 2 of the same pages open instead of 1

thorny spruce Jan 15, 2019, 4:55 AM

#

You have given your start button command =win, so when you press it it will give you another window

#

I'd suggest breaking your code up into sections so you don't get this mix or functionality

You can use .destroy to remove the widgets then create and pack/grid your new widgets

@digital rose best gui lib for what?

for simple app, you can use tkinter, but it looks ancient
for good looking app , may be pyside2 (if i right remember)
if you need crossplatform app packed to exemonofile then tkinter, wxpython, can do this, but both need "hack's" for crossplatforming, becuase mouse work different, and wxpython addon z-index of widgets opposite direction linux vs windows.

#

python is good for serverside and cli(command line interface/console inputs)...

serene spoke Jan 15, 2019, 6:43 PM

#

@obsidian lance @digital rose if you look at the image I posted a few messages up, you can see a sample of what tkinter is capable of. That app was made with zero external dependencies, created with everything available in the standard library. Tkinter doesn't have to look ancient if you take the time to understand how it works and to style it as you see fit.

tkk is a module within the tkinter library that allows you to skin your UI to look more native, as well as gives you more control as to how each widget looks.

#

@obsidian lance Python has a plethora of uses, not limited to server-side and cli applications.

obsidian lance Jan 15, 2019, 6:45 PM

#

i mean serverside and cli is comfort, but gui is always headpain and limited functionality

#

gui must have behavior close to html+js ... that not kill the coder in time of create and remaster something

serene spoke Jan 15, 2019, 6:50 PM

#

Perhaps it is for you, but that doesn't mean it may be for anyone else. Python is a perfectly acceptable language to write a user interface in. JS desktop applications typically use things like Electron, but that adds log(O(N^2)) bloat to your application.

obsidian lance Jan 15, 2019, 8:58 PM

#

sounds like you want say python tkinter gui more comfort for using in comparing with html + css + js? 🙂

#

even visual basic for excel 2003 more comfort than tkinter... The reason when i few times use tkinter is because i like how python language work, tkinter is prebuilded(on windows/linux need sometimes installing uses apt) and tkinter can be compressed to monofile exe uses pyinstaller ... that's all. Not comfort , but prebuilded , and can be packed to exe

#

I trying use eel python , but without success... even simple example just can't read functions from python to js object... and i can't fix it, and noone answer me on this server , what i do wrong

I was playing around with the noteboook widget but somehow I cannot get it to work, the main window remains a blank canvas when I try to compile the following:

class Application(tk.Frame):
    def __init__(self, master=None):

        self.ui()

    def ui(self):
            """ Tabbed Pages """
            self.notebook = ttk.Notebook(self)
            self.tab1 = tk.Frame(self.notebook)
            self.tab2 = tk.Frame(self.notebook)
            self.notebook.add(self.tab1, text="One")
            self.notebook.add(self.tab2, text="Two")
            self.notebook.grid(row=0, column=0)

            self.label3 = tk.Label(self.tab1, text="Label3!", width=20)

            self.label4.grid(row=0, column=0, sticky="W")

Any ideas?

Another question: consider the code snippet

            """ Menubar """
            self.menubar = tk.Menu(self)
            menu = tk.Menu(self.menubar, tearoff=0)
            # File
            self.menubar.add_cascade(label="File", menu=menu)
            menu.add_command(label="Open")
            menu.add_command(label="Save")
            menu.add_command(label="Save As")
            menu.add_separator()
            menu.add_command(label="Exit")

I know that I can change the font/size of a command with menu.add_command(label="Open", font=system) where system = font.Font(family="System", size=12) (imported from import tkinter.font as font) but when I try to apply the same logic to self.menubar.add_cascade(label="File", menu=menu) by manipulating the -font parameter nothing changes.

#

According to (http://effbot.org/tkinterbook/menu.htm), .config(**options) allows to set a new font but I cannot access this option because my code doesn't want to adhere to this option and yields an _tkinter.TclError: unknown option "-font" error

digital rose Jan 15, 2019, 11:12 PM

#

this site (https://www.tutorialspoint.com/python3/tk_menu.htm) also suggests that it should be possible to manipulate the options of menu methods but apparently its not that easy

#

I suppose it has something to do with the operating system; if a unix user could run

from tkinter import *

class TestMenu:
    def __init__(self, master):
        self.master = master
        self.menubar = Menu(self.master)

        self.cmdmenu = Menu(self.menubar)
        self.cmdmenu.add_command(label='Wild Font', underline=0, font=('Tempus Sans ITC', 14))
        self.cmdmenu.add('separator')
        self.cmdmenu.add_command(label='Quit', underline=0, background='white', activebackground='green', command=self.master.quit)

        self.unused = Menu(self.menubar)

        self.menubar.add_cascade(label="Button Command", menu=self.cmdmenu, font=('System', 14))

        self.top = Toplevel(menu=self.menubar, width=500, relief=RAISED, borderwidth=2)

def main():
    root = Tk()
    root.withdraw()
    app = TestMenu(root)
    root.mainloop()

if __name__ == '__main__':
    main()

and report whether or not the font/size off add_cascade(**options) changed that would be really great

digital rose Jan 15, 2019, 11:45 PM

#

i believe it's possible to use something like self.menubar.option_add("*font", system) I am not entirely sure what goes into the string; drawing from my experience with tkinter's combobox it looked like self.labelframe.option_add('*TCombobox*Listbox.font', system)
Edit: self.menubar.option_add('*Menu.font', 'System 12') doesn't work either

@dark lava pyinstaller?

#

first windows created exe , work only on windows. Linux created executable work only on same linux version... ubuntu,kubuntu,lubuntu can need have original version of executable... and 16.04 vs 18.04 too can have dependencies from os libs

#

Attempting to pass information from a QDialog to a MainWindow through a login verification function. to accomplish the widget switch I end the login verification function with a self.accept(). Is there a way to also return a dictionary?

The goal is to set up the profile in the Mainwindow without the user having to reinput their profile information again.

Alternatively, I could have the login verification create/check for a different database specific to that user to call the data.

Thoughts?

textBoxTeamID.bind('<Return>',self.storeTeamID(textBoxTeamID, frame,rootWindow)) the self.storeTeamID function automatically executes

#

Stackoverflow says remove the parentheses

#

But, then how do I pass these parameters?

#

https://www.paste.org/96705

Paste code - paste.org

www.paste.org - allows users to paste snippets of text, usually samples of source code, for public viewing.

#

What I am trying to do is to bind the Entry box to enter button

#

If entered is pressed inside Entry then storeTeamID is executed

thorny spruce Jan 17, 2019, 2:46 PM

#

You can use a lambda in this case

textBoxTeamID.bind('<Return>', lambda e: self.storeTeamID(textBoxTeamID, frame,rootWindow))```
Or if you want you can look at `functools.partial`

marble viper Jan 17, 2019, 2:52 PM

#

@thorny spruce Beautiful.

#

I tried textBoxTeamID.bind('<Return>', lambda: self.storeTeamID(textBoxTeamID, frame,rootWindow))but it didn't work

#

where as goButton = tk.Button(frame, text="Go!", command=lambda: self.storeTeamID(textBoxTeamID, frame,rootWindow)) button works without x in lambda x:

#

Is there any specific reason?

thorny spruce Jan 17, 2019, 2:54 PM

#

Yea because your example used bind where that one uses command=

marble viper Jan 17, 2019, 2:55 PM

#

So, when we use bind we use lambda e: because?

thorny spruce Jan 17, 2019, 2:56 PM

#

.bind passes a tkinter.Eventobject when triggered so your function needs to accept that parameter

marble viper Jan 17, 2019, 2:56 PM

#

Oh! Just like C#

#

Thank you!

#

Do you think I should make frame, rootwindow, and widgets member of the class?

#

https://paste.ofcode.org/eWwEc38Tk5wF9cLan2XwHa

#

Is it a good practice?

thorny spruce Jan 17, 2019, 2:59 PM

In this case you probably want to instead of just passing them around as parameters

@crude sparrow very nice! Perhaps I'll give PSG a look over ;)

#

I really think that a text widget with the option of having line numbers is a feature too often overlooked.

#

Right now I'm handeling it using a tk.Canvas, but I'm sure there are more performant and/or memory efficient solutions

#

Especially considering that all I'm doing with it is using create_text

@crude sparrow You've probably already seen it, but I think that perhaps making PSG work like https://github.com/pybee/toga might be a cool idea.

#

yeah but as you can see, there are multiple colours in the background xD

crude sparrow Jan 19, 2019, 1:59 PM

#

@dark lava With tkinter you won't be able to have the text alaph-blended onto the background. You could place text onto a graphic using a Canvas and a Canvas.create_text method call.

#

Qt will allow you to place widgets directly onto a background image

#

I am unsure about WxPython as I have not yet been able to get text composited onto an image.

crude sparrow Jan 19, 2019, 3:20 PM

You need to place your image in the same canvas as your text

#

To do that, call create_image

canvas.create_image

If you place the image and the text onto the same canvas, the result is this:

You'll need to save a copy of the image (fondo) if you're in a function. I created a list that was in my class and appended images to it as I created them.

I asked this before, and I am going to attempt again. In short, I have programmed a QDialog login form that checks a set user database prior to opening the main application. I found using the self.accept() function to work best. However, it only seems to return "Accepted".

What I am attempting to accomplish is returning at the very least a user profile so that the main application can access it to load up the user specific database. Currently, I have the login dialog and main window activated through a main application.

The code to follow will be snippets from both. the login script and the executing parent script.

First: the User Login function

def userLogin(self):
        lookupStatement = "SELECT Profile, Password FROM Users WHERE Profile like '" + self.ui.lineEditUserProfile.text() .lower() + "' and Password like '" + self.ui.lineEditPassword.text() + "'"
        # SELECT X, Y FROM Tablename WHERE X like 'X.data' + and Y like 'Y.data'
        conn = sqlite3.connect("UAInformation.db")
        cur = conn.cursor()
        cur.execute(lookupStatement)
        row = cur.fetchone()
        if row is None:
            self.ui.labelResponse.setText("User Does Not Exist.\n Create New User?")
            conn.close()
        else:
            self.ui.labelResponse.setText("Welcome!")
            conn.close()
            self.accept()

Second the script that I am using to bridge the login dialog and mainwindow.

import sys
import sqlite3
from PyQt5.QtWidgets import *
from UserLogin import *
from Alchemical_Finances import *

if __name__ == "__main__":
    app = QApplication(sys.argv)
    porcelainoffering = LoginForm()
    if porcelainoffering.exec_() == QDialog.Accepted:
        porcelaingod = AFBackbone()
        porcelaingod.show()
        sys.exit(app.exec_())

Thoughts on how i can get any data between the login and the mainwindow?

        self.ui.pushButtonCancelProfile.clicked.connect(self.cancelProfile)
        self.show()

fallen oxide Jan 19, 2019, 8:47 PM

#

ah, QDialog

#

one minute

#

OK, yeah, QDialog's result can't be arbitrary

#

but there's no reason you can't set an attribute yourself

#

literally, store it on self and then access it outside of the class with porcelainoffering.whatever

#

in the __init__, remember to set it to None first

#

and don't reuse LoginForms, make a new one every time you need it

sullen thunder Jan 19, 2019, 8:52 PM

#

I hate to be a bother, could you provide me a little bit of an explicit example. Not 100% sure i follow how to use the __init__

fallen oxide Jan 19, 2019, 8:52 PM

#

Well basically if you've got an expected attribute for your class, you don't ever want it to not actually exist

#

so in your __init__ you might set self.data to None

#

and then when you get that data, store it under self.data later

#

then when you need it, you can check porcelainoffering.data

#

from outside of the class

#

since that's where you store your LoginForm instance

sullen thunder Jan 19, 2019, 8:54 PM

#

so I would have something along the lines of def __init__(self.data) or you referring to the super().__init__(self.data)

fallen oxide Jan 19, 2019, 8:54 PM

#

neither

#

def __init__(self):
    self.data = None

sullen thunder Jan 19, 2019, 8:55 PM

#

Oh, then if i understand you correctly, I can set the self.data later via another function and call that

fallen oxide Jan 19, 2019, 8:55 PM

#

Yeah

#

eg in your userLogin I guess

#

whatever it is you're using

#

small note btw, but don't use * imports

#

it makes it hard to figure out where something is coming from, and it fills the module scope with a bunch of things you're not actually using

sullen thunder Jan 19, 2019, 8:57 PM

#

even for the self written code? Like for instance the login import is a qdesigner output

fallen oxide Jan 19, 2019, 8:57 PM

sullen thunder Jan 19, 2019, 8:58 PM

#

oh i just use the native python IDLE

fallen oxide Jan 19, 2019, 8:58 PM

#

you've definitely outgrown it

I recommend VS Code if you like something more lightweight, or PyCharm for the full blown heavy IDE

sullen thunder Jan 19, 2019, 8:59 PM

i have been considering PyCharm

fallen oxide Jan 19, 2019, 8:59 PM

#

I highly recommend it

#

if you were using it, what I was going to say

is that you can remove all those imports, find all the stuff that now has a red underline, go to it and hit alt+enter

#

and you can have it write the correct import for you

sullen thunder Jan 19, 2019, 9:00 PM

ahhh, thats a nice little feature

dapper orbit Jan 20, 2019, 4:20 PM

#

all elements maybe look too big in a resolution or too small in another resolutions

fallen oxide Jan 20, 2019, 4:21 PM

#

Start with the lowest resolution you intend to support and use that as your baseline

#

Your options after that are a little limited, but that's kind of intentional

#

The OS is what should be deciding how things should be scaled

#

You can also try to make your design responsive - collapsing menus and such

#

Another option might be to use different forms entirely for different resolutions

dapper orbit Jan 20, 2019, 4:23 PM

#

that what we have done a different forms but we was looking for more advanced ways

crude sparrow Jan 20, 2019, 5:30 PM

#

You are specifying these sizes in pixels? One way to do it would be to compute the size of the widget based on the size of a character. I use this technique, specifying sizes in characters, and it seems to work pretty well.

#

I do this when working with tkinter

fallen oxide Jan 20, 2019, 5:33 PM

#

I don't think that's possible with Qt

#

usually you set a minimum size or maximum size for something and let the layout handle the resizing

crude sparrow Jan 20, 2019, 5:34 PM

#

If you want an input field to be 30 characters wide, how is that specified in Qt?

#

QFont myFont(fontName, fontSize);;
QString str("I wonder how wide this is?");

QFontMetrics fm(myFont);
int width=fm.width(str);

#

I dunno, just a thought

proper glade Jan 20, 2019, 5:50 PM

#

QFontMetrics has a 'maxWidth' method that returns the width of the widest character in the font

#

so setFixedWidth(font_metrics.maxWidth()*n) where n is max number of characters

fallen oxide Jan 20, 2019, 6:03 PM

#

Most people are designing their UIs in the designer though

proper glade Jan 20, 2019, 6:19 PM

#

is that really the case?
i havent used designer so idk if there's some built-in way to override methods with your own code. but i do know you can use pyqt5/pyside2's uic tool to generate code from .ui files.

fallen oxide Jan 20, 2019, 6:21 PM

#

pyside2 does not require the uic tool anymore

#

you can straight up load the .ui files

proper glade Jan 20, 2019, 6:22 PM

#

i dont think pyqt5 does either, according to http://pyqt.sourceforge.net/Docs/PyQt5/designer.html

#

you need the pyuic5 module to load the ui file and code generation is provided as an option

crude sparrow Jan 20, 2019, 6:54 PM

I thought the problem being solved was the size of a widget in 2 different resolutions.

dapper orbit Jan 20, 2019, 6:56 PM

Is tkinter better than pyqt?

crude sparrow Jan 20, 2019, 6:56 PM

#

At what?

dapper orbit Jan 20, 2019, 6:56 PM

#

Generally

crude sparrow Jan 20, 2019, 6:57 PM

#

They're generally similar

#

If you want a small footprint .EXE file from PyInstaller, tkinter is the answer

#

If you want a "dial widget", Qt is what you want

#

If you want to run on a Raspberry Pi, tkinter is likely the "better" of the two

#

I dunno, I don't think it's possible to sum up something so complex into a single phrase

#

Is the snow more fun than the beach?

slow kelp Jan 20, 2019, 7:03 PM

#

I have the same problem with my project

#

So, what is the best way to handel this case

#

To use tkinter to size controls with pixels
Or use pyqt5 with more than one form for each resolution

crude sparrow Jan 20, 2019, 7:08 PM

#

The way I do it is to specify all my sizes in "characters". If a widget takes pixels instead of characters for a size, then I computer the pixels based on the size in characters multiplied by the size of a single character

slow kelp Jan 20, 2019, 7:12 PM

hey @crude sparrow what low-level tech is your lib based on? is it something like OpenGL?

fallen oxide Jan 20, 2019, 8:24 PM

I think it works with several UI libraries (eg, tkinter)

Is there a cross platform way of sending desktop notifcations?

#

Or at the least, a single way of doing it that covers most, if not all, linux distros

#

I don't mind handling osx and windows separately

obsidian lance Jan 21, 2019, 4:43 AM

#

@dapper orbit tkinter can be packed as mono executable file uses pyinstaller script.py --onefile --noconsole command... pyqt can't.
tkinter can't show unicode symbols with number greater than 65535 or close(forget neat).
Tkinter and pyqt are not similar, because tkinter is ancient and does not evolve , but native. Pyqt evolve to pyside2 etc, but not native/can be easy packed to exe and looks not so crossplatform(not so many targeted platforms as tkinter)

#

and tkinter widgets haven't id parameter inside default constructor... you need extend it manually... it looks really weird

echo coral Jan 21, 2019, 5:48 AM

#

@sudden coral have you seen ntfy? https://ntfy.readthedocs.io/en/latest/

#

covers not only native os notications but also various apis and web services

#

@sudden coral on linux it's pretty easy as you just run notify-send in a subprocess. on osx trickier, but thankfully apple made that objective-c to python bridge and thus native api access can be had. but ntfy does all that for you

sudden coral Jan 21, 2019, 5:55 AM

#

Sounds awesome. I'll check it out, thank you

echo coral Jan 21, 2019, 5:56 AM

#

works like a charm. i use it for tons of stuff across platforms

#

desktop notifications, slack bots, server alerts, etc

sudden coral Jan 21, 2019, 5:58 AM

#

Does it have an API or is it just supposed to be invoked via subprocess or something

echo coral Jan 21, 2019, 6:01 AM

#

installing it gets you the ntfy cli app, but it's also a library

#

you can do: ```import ntfy

ntfy.notify('some message', 'some title')```

#

and that'll send a native desktop notification

sudden coral Jan 21, 2019, 6:02 AM

#

Alright. The documentation must be sparse or I am just not looking in the right places then

echo coral Jan 21, 2019, 6:02 AM

#

there are no docs for the use as a library as far as i know

sudden coral Jan 21, 2019, 6:02 AM

#

I'll probably be able to figure it out anyway

echo coral Jan 21, 2019, 6:02 AM

#

but using it for at least a couple years for the same purposes i figured it out

#

but just that command is pretty much all you need. if you want to use the different api backends, that's all just a flat file config

gritty echo Jan 21, 2019, 8:05 AM

#

Using tkinter, is it possible to see if there's a module in a specified column and row in a grid?

obsidian lance Jan 21, 2019, 8:54 AM

#

@gritty echo module? may be you mean widget?

gritty echo Jan 21, 2019, 8:55 AM

#

I'm not sure the proper term: label, button, etc

obsidian lance Jan 21, 2019, 9:04 AM

#

not sure. My knowledge is weak, but i can imagine only next way:
1 - extend widget (add parameters myrow, mycol)
2 - in time of adding widget to container set the myrow,mycol
3 - when need check the cell empty or not, loop all widgets inside container and compare if myrow==1 and mycol==1 , then cell 1,1 is not empty
... but this not look comfort@gritty echo

slow kelp Jan 21, 2019, 12:14 PM

#

@obsidian lance what do u mean by mono executable file

#

Do u mean .EXE file ?

gritty echo Jan 21, 2019, 7:09 PM

#

The reason I want to do this is so I can make it so a function avtivates every timr except the first time

#

I don't want to paste a widget over an over, I want to delete it each time it passes through so there's only one

#

I'll send code in a min

#

https://pastebin.com/uSJSFsnS

Pastebin

def calculate(): playLevel=entLevel.get() curExp=entCurE...

#

I want to delete the old output each time the function happens

#

I figured I could check to see if a widget was there and if there wasn't, don't destroy it

#

otherwise do

gritty echo Jan 21, 2019, 8:14 PM

#

btw this is the call btnCalculate = Button(root, text="Calculate", command=calculate, font="Arial")

obsidian lance Jan 21, 2019, 8:29 PM

#

@slow kelp yes, i mean exe... but exe is only windows... linux is just executable but have no .exe at the name end, but work similar if double click

#

@gritty echo looks like you need only

create Label (mydisplay) once as python variable
every time you need change text on the label you need

mydisplay.configure(text="my new text or empty string")```

gritty echo Jan 21, 2019, 8:34 PM

#

Thanks :)

obsidian lance Jan 21, 2019, 8:34 PM

#

no need delete or check in this case... just change text

gritty echo Jan 21, 2019, 8:35 PM

#

It works

#

Thanks

#

Wasn't aware you could do that

Hello! I'm new developing a simple interface with tkinter and I'd like to know if exists some library/module with extended functionality widgets

#

May be some Text widget with copy+paste capability already implemented, for example

crude sparrow Jan 22, 2019, 6:25 PM

#

copy / paste already works for all of the GUI frameworks as far as I know. You should be able to paste into a text entry widget.

serene spoke Jan 22, 2019, 9:25 PM

#

@zealous wedge the Text widget in tkinter already supports copy/paste/undo/redo/select all.

zealous wedge Jan 22, 2019, 9:37 PM

#

@serene spoke @crude sparrow thank you, I see, I've tested now that I can't copy/paste once I set the state disabled

serene spoke Jan 22, 2019, 9:38 PM

#

yep, thats intended behavior

zealous wedge Jan 22, 2019, 9:38 PM

#

it's a read only Text

#

well not paste, but can't copy the content? 😢

serene spoke Jan 22, 2019, 9:39 PM

#

Do you perhaps know how to listen for events?

zealous wedge Jan 22, 2019, 9:40 PM

#

not yet, what should I listen?

#

it's a "copy content" event or should I capture the key stroke ?

serene spoke Jan 22, 2019, 9:42 PM

#

Capture the keystroke inside the widget.

zealous wedge Jan 22, 2019, 9:43 PM

#

ok, I'll find the docs

serene spoke Jan 22, 2019, 9:44 PM

#

Then when you've done that, simply enable the widget, do widget.edit_copy() or widget.event_generate("<<Copy>>") and then disable again

zealous wedge Jan 22, 2019, 9:44 PM

#

mmm....

#

is there a function to just copy de content ? To place a button to copy the entire Text content is enough for the purpose

serene spoke Jan 22, 2019, 9:46 PM

#

You can try widget.edit_copy() without re-enabling the Text area.

#

Can't guarantee that it will work.

#

Not while it's disabled, anyways.

zealous wedge Jan 22, 2019, 9:48 PM

#

thank you for the hints, I'll do some test, I wanna do the minor change in this code

zealous wedge Jan 22, 2019, 10:29 PM

#

master.bind('<Control-c>', lambda e: e.widget.event_generate("<<Copy>>"))```

#

it's called but does not copy the selected text

#

this works on Linux?

#

(master is the Tk() instance)

obsidian lance Jan 23, 2019, 1:46 AM

#

linux can have difference... i know only about mouse scrolling inside tkinter notebook... this need difference code for linux/windows... but include both variants of code without conflicts is possible@zealous wedge

serene spoke Jan 23, 2019, 1:54 AM

#

@zealous wedge py widget.bind("<Control-c>", widget.edit_copy())

people tend to use Tkinter as their first gui project. not because it is easy or good, but because it comes with python and have alot of documentation online

do you planned popup window inside your app?

digital rose Jan 24, 2019, 11:18 AM

it's going to display information to the user, based on what item they are looking for.

obsidian lance Jan 24, 2019, 11:19 AM

sounds like web site based, but you want make it with python gui... you are the boss... but it 99% will be harder than django or php way

Meh. Learning to do something different is far more useful.

sand warren Jan 24, 2019, 11:21 AM

if you are looking for a fast web based UI, then go for Flask

no, specifically not web based... otherwise i'd be in #web-development 😉

sand warren Jan 24, 2019, 11:21 AM

#

still, tkinter and you would have an ok looking application that works an all oses

#

if you are concerned about look, you would have to spend more time learning other GUI frameworks

digital rose Jan 24, 2019, 11:22 AM

#

Fair enough. i'll start with Tkinter.

obsidian lance Jan 24, 2019, 11:22 AM

#

do you have an sketch of gui?

digital rose Jan 24, 2019, 11:23 AM

#

the last GUI i did was in Java with Jpanel.

#

@obsidian lance : not yet, but it's simple enough.

obsidian lance Jan 24, 2019, 11:24 AM

#

if simple then tkinter is possibly not bad variant

#

and prepare for original solutions... for example tkinter widgets have no id parameters default... and you need extend base classes... but if you no need hard gui then just use python variables as widgets keepers

#

and if your database include for example email data standards ... then you will fail with all unicode character with numbers greater then 65535, but you can use little hacks(cut wrong symbols from text before displaying or switch to abrakadabra), or just can't show this text uses tkinter

#

this is tcl ancient lags... which still crush tkinter

@barren void some times ago (two years or close) python eel(python bridge to connect with javascript uses bottle python web micro framework) looks interesting, more lightweight than elektron (80mb vs 5mb hello world app), but few weeks ago i trying to use python eel , but it can't read functions from python that use it inside javascript side. As result not all web serv based ways can be good. Need testing

#

eel created for desktop app uses python + html js css

#

django is heavy but working

echo coral Jan 25, 2019, 7:41 AM

#

it's always been a difficult area if you wanted true cross-platform, but there are a lot of better , easier tools than there used to be. fbs (https://github.com/mherrmann/fbs), toga (https://github.com/pybee/toga), PySimpleGui as mentioned above

obsidian lance Jan 25, 2019, 7:43 AM

@echo coral i really like the eel way for this... it looks enough comfort... but sadly not work as expected 😐 . And i can't fix situation

echo coral Jan 25, 2019, 7:43 AM

#

also, a project that i really hope picks up even more -- libui (https://github.com/andlabs/libui). truly amazing because it's easy, it's truly native on every platform, and it has bindings for like 20 languages. python, js, lua, whatever you want. extremely promising, just can't do everything yet

echo coral Jan 25, 2019, 7:46 AM

haha no

#

just lots of subprocesses and poor IPC

#

but there are definitely ways like mentioned above that do work decently

#

and to be quite honest i think that's mostly good enough. most things do get used on the web

#

and js is likely the better approach in the end purely because react-native is making its way into desktop libs and when that picks up the performance will suck much much less

obsidian lance Jan 25, 2019, 7:49 AM

#

i tried use slack few times... when was kicked from some server , because create politic /religion hate discussion, but slack was terrible... so much lag's ... i was little bit shocked... and now trying be more accuracy, that not be kicked from discord... i don't like slack)

echo coral Jan 25, 2019, 7:49 AM

(libui though, if it gets more comprehensive, would be ideal and solve this for basically every language)

slack and discord are both js-based but slack is definitely much worse performance-wise

obsidian lance Jan 25, 2019, 7:52 AM

is libui can be used with python at this moment ?

and can i create mono exe file from libui app, uses pyinstaller my.py --onefile --noconsole?@echo coral

libui can be theoretically be written with these language bindings: https://github.com/andlabs/libui#language-bindings

GitHub

andlabs/libui

Simple and portable (but not inflexible) GUI library in C that uses the native GUI technologies of each platform it supports. - andlabs/libui

#

...but, like i said, it's not too adanced yet. it varies, based on how the core dev is going, between 'easy and amazing' to sometimes 'it does not compile at all'

#

it isnt something i would jump into now for something super important that needs to be comprehensive, but it's the project to keep an eye on

obsidian lance Jan 25, 2019, 8:01 AM

yep, i look around time to time... don't like toga elektron pyqt(because i want solid exe file for code, not interested make simple app as folder...)... need wait and observe to libui too

@obsidian lance Please don't encourage people to plagiarize

#

Most people come here to actually learn something themselves

#

@shy robin I'm not that familiar with tkinter, so I can't really help you with the correct solution, but I do notice some things about your code

#

First of all, you declare global bt in the main scope of you module/file; that doesn't do anything.
