Wow

proud socket Jul 9, 2018, 1:31 PM

#

I'm using QT Designer and wanna convert an .ui file to .py.
but in my /Python36 i don't have pyuic5.exe
and weird is i can run QT Creator inside example

fallen oxide Jul 9, 2018, 1:31 PM

#

pyuic5 - so you're using, what, pyqt5? pyside2?

proud socket Jul 9, 2018, 1:31 PM

#

pyqt5

fallen oxide Jul 9, 2018, 1:32 PM

#

hm, yeah, that should come with some kind of uic

#

check the scripts folder in your python install

proud socket Jul 9, 2018, 1:33 PM

#

Here's in my Python36/Scripts

📎 unknown.png

fallen oxide Jul 9, 2018, 1:34 PM

#

yeah that's pretty weird

#

you don't even have pip in there

proud socket Jul 9, 2018, 1:36 PM

#

pip is in my E:\Python not at Python36

fallen oxide Jul 9, 2018, 1:38 PM

#

Uh, but then that's a different Python install

proud socket Jul 9, 2018, 1:43 PM

#

oh , i see

#

somebody help GWnanamiKongouLewd

fallen oxide Jul 9, 2018, 1:46 PM

#

You need to make sure you have everything installed under the correct python install

#

it seems like you have multiple separate ones

proud socket Jul 9, 2018, 2:17 PM

give up temporarily, go back to tkinter........

midnight umbra Jul 9, 2018, 6:23 PM

#

Hello guys, I have a little trouble with basic Tkinter coding

#

'''Python

#

import tkinter as tk

root = tk.Tk()

frame = tk.Frame(root)
tk.Label(frame, text = "Pack demo of 'side' and 'fill'").pack()
tk.Button(frame, text = "A").pack(side = LEFT, fill = Y)```

#

gives the following error

#

Traceback (most recent call last):
File "tkinter-geometry_test.py", line 9, in <module>
tk.Button(frame, text = "A").pack(side = LEFT, fill = Y)
NameError: name 'LEFT' is not defined

silk fjord Jul 9, 2018, 6:33 PM

#

@midnight umbra tk.LEFT I believe

#

LEFT isn't a constant in your code, it's a constant in tkinter's package

#

So you have to access it with tk.

midnight umbra Jul 9, 2018, 6:34 PM

#

you are right

#

I won't import tkinter as tk anymore it will be so damn long to write tk.constant everytime

silk fjord Jul 9, 2018, 6:35 PM

#

I wouldn't clutter your namespace with all of tk's functions

#

It's better to write tk. before tkinter functions

#

Not only will it tell other coders that code is from tkinter but it won't horribly fuck up your namespace

midnight umbra Jul 9, 2018, 6:35 PM

#

so what is the better choice

silk fjord Jul 9, 2018, 6:35 PM

#

tk.LEFT

#

Even if you have to write more letters

midnight umbra Jul 9, 2018, 6:36 PM

#

OK very nice, I will make a habit out of it.
do you do that to ?

#

too?*

silk fjord Jul 9, 2018, 6:37 PM

#

I used to do it with the from tkinter import * way but as I grew out of my beginning stages I realized how bad of an idea it was

#

When I work with imports unless it's one or two specific functions I'm importing, I never use from x import y

#

If I need the entire package you always want to import x as y or just import x in the case of stuff like re

midnight umbra Jul 9, 2018, 6:38 PM

#

Ok thanks for the advice, back to Tkinter.
Good night man

silk fjord Jul 9, 2018, 6:39 PM

#

See ya

digital rose Jul 10, 2018, 1:03 AM

#

@floral jungle just to let you know I solved the issue on my own

#

class ScreenNearUsers(Screen):



    @mainthread
    def on_enter(self):
        for i in xrange(101):
            button = Button(text="B_" + str(i))
            self.ids.grid.add_widget(button)```

#

you were right it was running the code before checking the kv file

#

so I had to use from kivy.clock import mainthread

#

figured this out from reading the docs over

floral jungle Jul 10, 2018, 1:16 AM

#

@digital rose oh man, that is a pretty terrible thing to happen though

#

sounds like a bug to me

lavish flare Jul 10, 2018, 2:01 AM

anyone have any ideas on how to add a timer into my pyqt interface

#

code is posted in #help-coconut atm

i want the timer to appear where the top line edit is

wraith apex Jul 10, 2018, 9:19 AM

sorry, I personally have no experience with PyQt but I felt like it was kinda rude to leave you here with no answer at all

lavish flare Jul 10, 2018, 12:35 PM

#

@wraith apex I don't need it to be pyqt I just need a countdown timer and two buttons

#

If you are familiar with another gui type can you help me get it working?

wraith apex Jul 10, 2018, 12:36 PM

#

you actually want a timer in the... window?

lavish flare Jul 10, 2018, 12:36 PM

#

Yea

flint citrus Jul 10, 2018, 12:36 PM

#

Usually you'd just update the widget's text value on an interval, right?

lavish flare Jul 10, 2018, 12:36 PM

#

Timer in the top middle, buttons at the bottom

#

Score board in the exact middle

#

That's what I was doing with qtimer

#

But it wasn't working

#

I figured go use pyqt because I already had qt installed for c++ and the pi im using also has pyqt installed already

#

But i can use whatever interface method I want it just has to be a .py

flint citrus Jul 10, 2018, 12:40 PM

#

I'm not sure about qt, but in Tkinter (for example) you'd have a StringVar assigned to the widget, and when you updated the StringVar the widget's text would change as well.

lavish flare Jul 10, 2018, 12:41 PM

#

I'm not familiar with tkinter so can you give an example of timer code?

flint citrus Jul 10, 2018, 12:42 PM

#

Before we go rewriting everything, what did you try with qtimer?

lavish flare Jul 10, 2018, 12:43 PM

#

Making a central widget where it prints an int that updates every second

#

The code works by itself

#

But I get an error when I try to implement it into my interface

#

Tells me ui_form has no member central widget

#

I've browsed stack overflow (posted there too) for the last almost 4 days and still havnt fixed it

flint citrus Jul 10, 2018, 12:48 PM

#

Do you have the source code?

lavish flare Jul 10, 2018, 12:50 PM

#

I, someone just picke posted an answer on stack overflow but their answer doesn't work should I post their answer or my code?

#

Or maybe the the questions address

#

Wait holy shit I changed a line it's working

#

From his answer

flint citrus Jul 10, 2018, 12:52 PM

#

Stack Overflow comes through again!

lavish flare Jul 10, 2018, 12:53 PM

#

He forgot one line but I think that's my PC not his code

#

Oh thank God

#

I've worked so long on this code and not made progress I'm so happy it's working

#

thanks for trying to help ill probably be back her asking for help again when i need the gui to capture controller inputs haha

Hello sweet little ppl of Tkinter, I have a question
what is the difference between a Frame and a PanedWindow ?

midnight umbra Jul 10, 2018, 3:24 PM

what do you mean by features

#

you can insert more widgets in a PanedWindow than in a Frame ?

midnight umbra Jul 10, 2018, 4:27 PM

hey does anyone know a different message type box for displaying a quick message?

#

currently i have QMessagebox.queston

#

which while it works has a big ugly questionmark in the middle of it

#

#

i just want the text and button centered if possible

midnight umbra Jul 10, 2018, 8:34 PM

I can tell you but first you have to answer me

lavish flare Jul 10, 2018, 8:35 PM

whats your question

midnight umbra Jul 10, 2018, 8:36 PM

#

what is the difference between a Frame and a PanedWindow

lavish flare Jul 10, 2018, 8:38 PM

#

im not sure exactly but i believe a paned window is resizable while a frame is set based on parameters

midnight umbra Jul 10, 2018, 8:38 PM

#

Ok ty mate
I don't know the answer for your question I am sorry I am a supernewbie

#

have a good night

rotund flax Jul 10, 2018, 8:39 PM

#

Don't do the whole "I'll answer if you answer me thing"

#

especially if you at first say you know and then you don't know

midnight umbra Jul 10, 2018, 8:40 PM

#

yeah sorry won't happen again

lavish flare Jul 10, 2018, 9:21 PM

#

i figured it out sorta

#

its not completely centered but the about box will display it without the extra question mark or exclamation for urgent

#

Hi, I am new here. I wrote a jupyter notebook tkinter app and wanted to make it into a package for better code separation, unit testing, ability to refactor... The code is in nested directories and the imports to glue the formerly flat code together are beyond me. I have tried several variations and just want to be as Pythonic as possible. I looked for answers and more importantly example code, but haven't quite found any.

Perhaps all I need is a link to some good example code of a nested GUI app that has multiple windows.

My problem summed up;
https://github.com/kurtu5/Labeler/blob/master/Labeler/Docs/readme.txt

I also tried the imports with a smaller piece of test code;
https://github.com/kurtu5/NestedAppImportTesting

I can get it all to work, but it seems to be straying away from a Pythonic way. Test snippits are prepending to sys.path in order to work and it just seems wrong. Any pointers? Any code examples? Any directives to just stop and do it another way?

@floral jungle I think your right, I was reading the docs more and when you use Builder to directly call the kv file mainthread is not needed but, it was the only way I could get it to work 🤔

who knows a good graphics display module for python that might run faster than pygame?

📎 2018-07-10_09-57-47.gif

that suits my needs

digital rose Jul 12, 2018, 3:46 PM

#

maybe Turtle @daring locust

daring locust Jul 12, 2018, 3:46 PM

#

turtle? oh god no

#

thats at least 1000x slower

digital rose Jul 12, 2018, 4:16 PM

#

with delay(0) and speed(10) and mainloop is instantly

#

@daring locust

digital rose Jul 12, 2018, 4:38 PM

but instead of faster, you can make it smoother

daring locust Jul 12, 2018, 9:52 PM

it is smooth. my gif is only 30 fps @digital rose

its as smooth as silk

Hi, i want to replace some letters with other letters when user inputs text in entry widget. First i should get the entered text with entry.get() method, then after that what should i do? (Tkinter)

obsidian lance Jul 13, 2018, 2:02 PM

#

@fast wave looks like you want filter incoming data on the fly?

obsidian lance Jul 13, 2018, 2:23 PM

#

@fast wave may be you need something like this? python 3.6 tested

import time

import threading



def updateDisplay(myString):
    displayVar.set(myString + ' --- ' + time.ctime())



root = Tk()

displayVar = StringVar()

displayLab = Label(root, textvariable=displayVar)

displayLab.pack()

def printit():
  threading.Timer(2.0, printit).start()
  updateDisplay("bang")

printit()

root.mainloop()```

fast wave Jul 14, 2018, 9:42 PM

#

Your code gives error about textvariable i dont know why.
I want to replace these letters (gx, jx, hx, ux, cx) with (ĝ, ĵ, ĥ, ŭ, ĉ) when user types them in entry box.

#

First i have to get the entered text with entry.get() method. Then i dont know what to do :(

shrewd lark Jul 15, 2018, 1:41 AM

#

what is the best way to have 2 separate scripts for tkinter buttons and adding them into the ui into a different script?

#

like how would i be able to do that?

kind kraken Jul 15, 2018, 1:54 AM

#

@fast wave instead of replacing text after the fact, how about a key event that makes 'x' apply the accent to the previous letter?

shrewd lark Jul 15, 2018, 6:21 AM

#

Could someone respond to my question ;-; pls

fast wave Jul 15, 2018, 7:27 AM

#

@kind kraken oh that's better. How can i do that? finger_gun

kind kraken Jul 15, 2018, 2:40 PM

#

@fast wave .bind to set a key event, entry.index(INSERT) to find where the cursor is. Then just do entry.delete(ins-1, INSERT) to remove the existing g/j/h/u/c/s and entry.insert(INSERT, x) to place the accented one.

fast wave Jul 15, 2018, 7:04 PM

#

How should i specify which accent it have to put on the letter? Because the accent for u is different from others c,g,j,h

hoary lodge Jul 15, 2018, 10:28 PM

#

@shrewd lark idk myself but try asking in a help channel

kind kraken Jul 16, 2018, 12:09 AM

@fast wave I'd probably just use a dictionary of letter -> accented letter

import tkinter as tk
root=tk.Tk()
root.geometry("400x400+400+400")

l1=tk.Label()
l1.pack()
l2=tk.Label()
l2.pack()

root.bind('<Key>', lambda e: l1.config(text=e.keysym), True)
root.bind('<Up>', lambda e: l2.config(text='<Up>'), True)
root.bind('<space>', lambda e: l2.config(text='<space>'), True)
tk.mainloop()

Any idea how to use bind here so that <Key> captures <Up> and <space> as well? Currently it won't iif the two bottom binds are set. Is this just the way tkinter is?

#

Of course the obvious workaround is to not ever use anything but '<Key>' and have a generic on_keypress(event) sort it out. But I was wondering if there was something else.

kind kraken Jul 16, 2018, 6:31 PM

#

@thin plover what is the "True" argument you are passing to bind?

thin plover Jul 16, 2018, 6:32 PM

#

That allows multiple binds.

#

root.bind('<Key>', lambda e: l2.config(text=e.keysym))
root.bind('<space>', lambda e: l2.config(text='<space>'), True)

If the second bind didn't have True set, it would replace all the binds on root with itself. With True it appends itself to the tk callback structure

kind kraken Jul 16, 2018, 6:34 PM

#

ok i was confused because the documentation suggests it has to be '+'

#

but changing that doesn't seem to help

#

might just be that's how tk is

thin plover Jul 16, 2018, 6:35 PM

#

so rootbinds={somekey: somecallback1, someotherkey: somecallback2} instead of
only {someotherkey: somecallback2}

kind kraken Jul 16, 2018, 6:35 PM

#

you could put your bindings in functions, and have the other functions call the <Key> function at the end

#

er, also i don't think that's true

#

afaik it appends to the list of bindings for that key

thin plover Jul 16, 2018, 6:35 PM

#

tk is strange and tkinker is just a wrapper to wierd tk objects

kind kraken Jul 16, 2018, 6:35 PM

#

vs replacing

thin plover Jul 16, 2018, 6:36 PM

#

yeah, you are right its by 'key'

#

i think just having the most gneric on_keypress(event) method that I implement myself will work around this.... i could have dove into the strange tk structures

kind kraken Jul 16, 2018, 6:37 PM

#

hmm

#

tk allows you to bind globally or on a widget class instead of on a specific widget, i wonder how you do that in tkinter

#

not related to your issue, just curious

thin plover Jul 16, 2018, 6:38 PM

#

parent.tk.call('bind', parent._w, sequence, None)

#

that does return all the callbacks, probably a good reason to really refactor into PySide2

#

import tkinter as tk
root=tk.Tk()
root.geometry("400x400+400+400")

l1=tk.Label()
l1.pack()
l2=tk.Label()
l2.pack()

root.bind('<Key>', lambda e: l1.config(text=e.keysym))
root.bind('<Key>', lambda e: l2.config(text=e.keysym), True)
root.bind('<space>', lambda e: l2.config(text='<space>'), True)
print(root.tk.call('bind', root._w, '<Key>', None))
tk.mainloop()

The reason I used True was if somehow <Up> was internally renamed to the <Key> sequence.

if {"[2185688006536<lambda> %# %b %f %h %k %s %t %w %x %y %A %E %K %N %W %T %X %Y %D]" == "break"} break

if {"[2185748146440<lambda> %# %b %f %h %k %s %t %w %x %y %A %E %K %N %W %T %X %Y %D]" == "break"} break

Well, I'll jut stick with using my own on_keypress() method and just listen to the <Key> sequence event

kind kraken Jul 16, 2018, 6:49 PM

#

probably they did it that way because otherwise there'd be no way to know if you intended for <Key> to execute before or after the specific keys

thin plover Jul 16, 2018, 6:50 PM

#

Good point, that way it either works as intended or doesn't. No strange race conditions.

fast wave Jul 17, 2018, 9:37 PM

#

why can't i get the cursor position in my entry widget in edit_input function ? i tried many things. i used tk.StringVar there. i used self.entry_search.INSERT, i used search_var.get, search_var.INSERT. none of them works.

#

https://paste.pound-python.org/show/DLCMHSLTWlJ9CKVPSyaT/

#

what am i doing wrong? 😦

#

and also instead of replacing accented letters from words list which i've created, it writes multiple letters from char list with 1 from words list

#

like in here you see the entrybox writes gibbrish

hi. when i click on a listbox item, the listbox items disappear. how can i fix this issue? https://paste.pound-python.org/show/F1nwcML2ACvFsf1nBeNY/

kind kraken Jul 18, 2018, 8:03 PM

#

lol

#

i just figured it out

#

it's because you're filling in the box with "Type to Search"

#

so it searches for "Type to Search"

#

try this:

#

    def update_list(self):
        self.listbox.delete(0, tk.END)
        search_term = self.search_var.get().lower()
        if search_term == 'type to search':
            search_term = ''
        self.cur.execute("SELECT Esperanto FROM Words ORDER BY Esperanto")
        for row in self.cur:
            item = row[0]
            if search_term in item:
                self.listbox.insert(tk.END, item)

    def entry_delete(self, tag):
        if self.entry_search.get() == 'Type to Search':
            self.entry_search.delete(0, tk.END)
        return None

    def entry_insert(self, tag):
        if self.entry_search.get() == '':
            self.entry_search.insert(0, "Type to Search")
        return None

#

wait a minute

#

you could be doing this in the sql:

   def update_list(self):
        self.listbox.delete(0, tk.END)
        search_term = self.search_var.get().lower()
        if search_term == 'type to search':
            search_term = ''
        self.cur.execute("SELECT Esperanto FROM Words WHERE ? IN LOWER(Esperanto) ORDER BY Esperanto", (search_term,))
        for row in self.cur:
            item = row[0]
            self.listbox.insert(tk.END, item)```

#

(Honestly though it might be simpler just to get rid of the "type to search" stuff)

fast wave Jul 18, 2018, 8:12 PM

#

it gives error about that IN LOWER you wrote

kind kraken Jul 18, 2018, 8:12 PM

#

wait, yeah, i'm wrong

#

it should be WHERE LOWER(Esperanto) LIKE ? and ('%'+search_term+'%',)

fast wave Jul 18, 2018, 8:15 PM

#

oh nice

#

it works 😀

#

don't you know what i should do about that { } which i've told you before?

#

look

📎 Capture.PNG

#

i don't want those { } around them

kind kraken Jul 18, 2018, 8:27 PM

#

how was your database created?

#

I don't think it's your program that's doing that, i think the { } must just be there in the database

digital rose Jul 18, 2018, 8:43 PM

#

The little icon in the window thing?
Like the picture above.

fast wave Jul 18, 2018, 8:43 PM

#

in db it doesn't have { }

📎 Capture.PNG

#

@digital rose yes that's the window icon. you can set that with master.iconbitmap("Esperanto.ico") (in between " " you should write the name of the pic which is in the directory of your program)

kind kraken Jul 18, 2018, 8:45 PM

#

hmm, i'll look at it

digital rose Jul 18, 2018, 8:45 PM

#

Ok thx.
@fast wave

kind kraken Jul 18, 2018, 8:45 PM

#

oh, i see

#

yeah, you've got the same problem again

#

row is a tuple, so you're trying to insert the tuple into the textbox, and apparently that's what it does

#

you need self.textbox.insert(tk.END, row[0])

fast wave Jul 18, 2018, 8:48 PM

#

@kind kraken it works. thanks a lot 😀

#

if i want to add functionality to my button and make it do what the curselection does, i know i should .bind Return key to it so that it searches with enter pressed. but how should i do the rest of the stuff?

kind kraken Jul 18, 2018, 8:53 PM

#

i'm not sure what you're asking

fast wave Jul 18, 2018, 8:54 PM

#

when user types the word in entrybox which exist in the list, upon pressing enter, i want that button to work and print the meaning in text widget. just like curselection does when clicked

kind kraken Jul 18, 2018, 8:57 PM

#

you could probably just set the selection on the list, and then your list stuff will fire

fast wave Jul 18, 2018, 8:57 PM

#

how should i do that ?

#

that's exactly what i want

kind kraken Jul 18, 2018, 9:00 PM

#

try listbox.selection_set(0)

fast wave Jul 18, 2018, 9:02 PM

#

i should write a function for that and bind it to button? or no ?

kind kraken Jul 18, 2018, 9:03 PM

#

try it and see

#

anyway i need to go for today

fast wave Jul 18, 2018, 9:04 PM

ok thanks. 👍

@craggy hollow TKinter?

shell blade Jul 19, 2018, 9:18 AM

#

@craggy hollow Have you checked out grid() yet?

#

or pack()?

#

iirc you can use pack with an argument for east or west, which will pack each element right or left of the previous element

#

Or you can just increment the column argument for grid

#

I haveen't used tkinter for months though, but the docs page is pretty clear and there are videos explaining grid() and pack()

#

(I recommend using grid when possible)

craggy hollow Jul 19, 2018, 12:42 PM

#

Yeah tkinter and I know grid

fast wave Jul 19, 2018, 1:18 PM

#

@craggy hollow like this for example:

#

button.grid(row=0, column=0)
button2.grid(row=0, column=1)
button3.grid(row=0, column=2)```

#

how can i get my current listbox index and make it work with the button which i've binded to? https://paste.pound-python.org/show/o9oWJatONgv8tuq86ikd/

#

in function search_word

#

i want my button to work like curselection of the listbox

kind kraken Jul 19, 2018, 1:39 PM

#

for this i'd probably just pack left

solar isle Jul 19, 2018, 7:30 PM

#

can someone tell me how to adjust labels with entry boxes or any widget for that matter in tkinter...

#

Here is my specific code

#

import sqlite3
from tkinter import *

enc = "Encrypt"
dec = "Decrypt"


window = Tk()
window.title("Caesar Cipher by AlphaSierra")
window.geometry("640x320")
window.configure(background="white")

lb1 = Label(window, text="Message: ", bg="white")
lb1.pack(side="left")

lb2 = Label(window, text="Key: ", bg="white")
lb2.pack(side="left")

msg = Entry(window, width=50)
msg.pack(side="left")

key = Entry(window, width=50)
key.pack(side="left")

def clicked():
    pass

encrypt_button = Button(window, text="Encrypt", bg="white", fg="black", command=clicked)
encrypt_button.pack()

decrypt_button = Button(window, text="Decrypt", bg="white", fg="black", command=clicked)
decrypt_button.pack(after=encrypt_button)

msg.focus()
window.mainloop()

#

import sqlite3
from tkinter import *

window = Tk()
window.title("Caesar Cipher by AlphaSierra")

msg.focus()
window.mainloop()

kind kraken Jul 19, 2018, 7:50 PM

#

What exactly do you want it to look like

#

I'd probably use a grid for what you're doing. Or at least pack them in the order you want them to appear in

solar isle Jul 19, 2018, 7:57 PM

#

I fixed it a little bit

#

from tkinter import *


window = Tk()
msg = Label(window, text="Message")
msg.grid(row=0, sticky=W)
key = Label(window, text="Key    ")
key.grid(row=1, sticky=W)
msg_en = Entry(window)
msg_en.grid(row=0, column=1, sticky=E, columnspan=2)
key_en = Entry(window)
key_en.grid(row=1, column=1, sticky=E, columnspan=2)
en_btn = Button(window, text="Encrypt")
en_btn.grid(row=2, column=1, sticky=E)
de_btn = Button(window, text="Decrypt")
de_btn.grid(row=2, column=2, sticky=E)
window.mainloop()

#

How do I make it responsive

kind kraken Jul 19, 2018, 7:57 PM

#

set the column weight

#

grid.columnconfigure(1, weight=1)

#

and if you want the message box to be able to be taller, you need a Text instead of an Entry

solar isle Jul 19, 2018, 8:01 PM

#

from tkinter import *


window = Tk()
msg = Label(window, text="Message")
msg.grid(row=0, sticky=W)
key = Label(window, text="Key")
key.grid(row=1, sticky=W)
msg_en = Entry(window)
msg_en.grid(row=0, column=1, sticky=E, columnspan=2)
key_en = Entry(window)
key_en.grid(row=1, column=1, sticky=E, columnspan=2)
en_btn = Button(window, text="Encrypt")
en_btn.grid(row=2, column=1, sticky=E)
de_btn = Button(window, text="Decrypt")
de_btn.grid(row=2, column=2, sticky=E)
window.columnconfigure(1, weight=1)
window.mainloop()

#

How do I fix the window size

kind kraken Jul 20, 2018, 3:41 AM

#

@solar isle what's wrong with the window size?

#

also the entry boxes should have sticky=E+W

Hi, I am learning PyQt5 at the moment and I have come across a similar error (presumably on my end) a couple of times. Namely, if I add a grid layout or a QHBoxLayout it does not actually implement when I run it.

      title = QLabel('Title')
        author = QLabel('Author')
        review = QLabel('Review')

        titleEdit = QLineEdit()
        authorEdit = QLineEdit()
        reviewEdit = QTextEdit()

        grid = QGridLayout()
        grid.setSpacing(10)

        grid.addWidget(title, 1, 0)
        grid.addWidget(titleEdit, 1, 1)

        grid.addWidget(author, 2, 0)
        grid.addWidget(authorEdit, 2, 1)

        grid.addWidget(review, 3, 0)
        grid.addWidget(reviewEdit, 3, 1, 5, 1)

        self.setLayout(grid)

This is an example of the code that does not seem to work. Are there any elements that might cancel this layout style out or what? I tried moving it up to be the first thing defined.

kind kraken Jul 22, 2018, 4:13 AM

#

@loud sapphire did you try making setlayout first, before adding anything?

#

also what is self? I think you can't setLayout on a top-level window

#

anyway, what you're doing to make the rowspan 5 on the reviewEdit isn't really good practice, you want ```py
grid.addWidget(review, 3, 0)
review.setAlignment(Qt.AlignTop)
grid.addWidget(reviewEdit, 3, 1)
grid.setRowStretch(3, 1)

#

anyway it works for me, i'd need to see the rest of your code for why it doesn't work for you

Another question about PyQt.. I have a button that opens the file browser and after choosing a file it SHOULD make it into a graph, just like the function in the imported file does, but I can't get it to connect anyhow.
The function should take an x as a value and use pandas to read it and matplotlib to make it into a graph, but after choosing the file the program just closes.
How can I get it to use the chosen file as the x in the function?

digital rose Jul 22, 2018, 4:35 PM

#

What does the code look like?

loud sapphire Jul 22, 2018, 5:13 PM

#

I have tweaked it a bit, but now it's down to this (the function calling)

    def to_graph(self):
        filter = '*.csv'
        name = QFileDialog.getOpenFileName(self, 'Open File', filter)
        fs.grapher(name)

I wrote an exception into the main function and it returns it, meaning for some reason the pandas and matplotlib can't do their job with the retrieved csv file.

#

imported the other file in as fs and grapher is the name of the function.

#

Oh, stumbled upon a solution!
Adding [0] to the name in the callout fixed it. Apparently it returns a tuple otherwise

digital rose Jul 23, 2018, 5:25 AM

Currently using Tkinter but just to make a simple GUI application. I will be making a game from scratch. Trying to find the best library/tools for it. If anyone knows the most efficient possible way to accomplish this please inform me. Thanks

Hi!
I am opening a file with Qt and reading it in a QTextEdit class.
I made a save function for this also, but it doesn't seem to work and crashes the program.
The save function opens a new file to write into and takes the text from QTextEdit to overwrite whatever the new chosen file is.
Am I not going about this correctly?

    def file_save(self):
        name = QFileDialog.getSaveFileName(self, 'Save File')
        file = open(name, 'w')
        text = self.textEdit.toPlainText()
        file.write(text)
        file.close()

@digital rose in general you need to make a borderless window and draw the border yourself... trying to do this in tkinter will be an uphill battle.

digital rose Jul 24, 2018, 2:47 AM

#

I want to keep users from being able to go to other parts of the app before they login. Im using kivy, I all ready have it setup to when the app launches the login screen pops up. The only issue is when they click a Button on the action bar it allows them to go to other screen.

#

What would be the best way to keep them from being able to go to any parts of the app before they login?

digital rose Jul 24, 2018, 3:28 AM

#

@kind kraken Thanks. I'm going to make this application in C++ I believe.

kind kraken Jul 24, 2018, 3:28 AM

#

that's probably smart. you could probably do it in PyQt, but this is the sort of thing that may well be easier with plain old win32

#

especially since to do it right, you have to handle WM_NCHITTEST to tell the system where your close box and borders are.

Why is PyQt so poorly documented? Does no one bother to translate the documentation from C++?

digital rose Jul 25, 2018, 3:00 PM

#

Methods and classes are the same as in c++

kind kraken Jul 25, 2018, 3:15 PM

makes me wonder

#

are there any gui libraries that are written in a pythonic way

#

tkinter and pyqt are as thin a wrapper around tcl and c++ respectively as they can get away with

tidal drum Jul 25, 2018, 3:32 PM

#

hi is it posible to add my_window.mainloop() <---- this is TKinter

#

to an asyncio event loop??

#

well i guess not

#

print(type(printio)) # >>>> <class 'function'>
print(type(window.mainloop)) # >>>> <class 'method'>

#

do i have to rewrite tkinter to use it with python 3.7 async/await ??

#

or is there some way ?

for a noob like me is more or less a nice book but the idea i have in mind takes data from scraped webs so it made more senso to try to implemnt it in an async way

#

Hi! I wanna make some app with vector graphics which will animate opeartion of a railroad. Intension is to be something like SCADA system. I have some app which will emulate things in back like sensor data gathering positions of trains etc. What is goto package for making such things with lets say GTK or QT in python

#

I am thinkinking something like making SVG every time change happens and just render it on app

#

But that is just for view, i want the things in interface to be for example clickable

digital rose Jul 26, 2018, 8:15 PM

When i run this

from tkinter import *

def printHello():

def printyo():

def printidk():
    print("idk")

root = Tk()
root.title("Press Buttons to Print")

text1 = Label(root, text = "VVVPress any buttonVVV").pack()

btnHello = Button(root, text = "Hello", command = printHello).grid(row = 0, column = 0)
btnyo = Button(root, text = "yo", command = printyo).grid(row = 0, column = 1)
btnidk = Button(root, text = "idk", command = printidk).grid(row = 1, column = 0)

root.mainloop()

#

it gives me this error:

 _tkinter.TclError: cannot use geometry manager grid inside . which already has slaves managed by pack

#

y is dat?

charred thunder Jul 26, 2018, 9:26 PM

#

you're .pack()ing a widget to the root, but then you're trying to .grid() the next one in root too. choose a method and stick to it @digital rose

digital rose Jul 26, 2018, 9:53 PM

oohh I didn’t know that I should choose 1 method

just writing a function docstring for a tkinter program. when .binding something, would the function passed be called the event handler? i.e,

    def _aspect_ratio(self, event):
        """
        An event handler to ...
        """

#

(i know i don't need to put docstrings in _methods but i like to)

thin plover Jul 29, 2018, 6:04 AM

@charred thunder It's just as cunfsing to me as what what the proper names are. We have, events, callbacks, slots, signals. It seems to depend on how you do code separation.

very well. i decided to call it an event handler because it handles the event ¯_(ツ)_/¯

Many different names for the same thing?

That's unpythonic.

charred thunder Jul 29, 2018, 6:10 AM

it's like how i got really confused between functions, methods, procedures and subroutines when i first started programming

shell blade Jul 29, 2018, 6:13 AM

#

there is technically a difference between a function and a method though

#

method: object.function(args)
function: function(args)

charred thunder Jul 29, 2018, 6:32 AM

#

yeah i know

#

i think i heard somewhere that procedures would have no return value, but i think they just mean the same as subroutines

shell blade Jul 29, 2018, 6:35 AM

#

Wouldn't a subroutine imply that it runs for the entire duration of the program?

charred thunder Jul 29, 2018, 6:36 AM

#

that might be a subprocess

#

or nah

#

according to google a subroutine is basically any sort of function or method

thin plover Jul 29, 2018, 6:44 AM

#

Yeah in my tkinter app i have binds(func=something1) and buttons(command=something2)... are both the same thing? def something1() -vs- defsomething2(event) are both event handlers? is one a callback and the other an event handler? whats worse is I have a hand made MVP framework and the View sends stuff to an Interactor, that in turns sends stuff to the Presenter.... on_something1? on_something2? lots of duplicate names in each layer to keep View and Presenter decoupled.

#

at least the decoupling is making it easy to convert it from tkinter to pyside

Did anyone try to reproduce tkinter form _tkinter module ?

@digital rose why would anyone do that?

#

Xd

digital rose Jul 30, 2018, 6:58 PM

#

because tkinter is written with poor OOP implementation

#

if you look at the source code from tkinter.py in py2.7 and tkinter\__init__.py in py3.6 you will see that there is progress but still tcl isnt transcribed all the way into OOP

#

so instead of minimise function that will show and hide the window, you need to call 3 to 4 seperate functions called by self.tk.call

#

and you can actually change master in tkinter, but it is difficult and generates copies of itself

kind kraken Jul 30, 2018, 7:00 PM

#

I suspect it's that anyone who's bothered by that is more likely to switch to a different ui toolkit than improve tkinter

digital rose Jul 30, 2018, 7:01 PM

#

true... but tcl is really awesome

#

you can with 2 code modules (one if you use builtin xml parser )change so you can make gui in xhtml+css and then implement it with tcl.tk

#

the only way you can't do that in python is because _tkinter.pyd is used as phraser where you can not pass a unique string to tcl object , but must pass tuple in argument form.

#

which limits the changing the individual states of each attribute of windows manager and every other tcl component

#

and tcl uses similarly hierarchy syntax as python relative import .module is same as .frame.

crimson spruce Aug 2, 2018, 3:13 AM

#

I'll confirm, as someone who both loves Python and Tkinter and has used both for at least 4 years, neither of them are suited for serious applications. Tkinter runs through a TCL interpreter built into Python, so it's likely to be slower than Python. Python is not a speedy-go-quicc language, it's usually slower than alternatives.

If you're just writing something quickly or as a demo, sure, use Python and Tkinter. For anything else, use something else... perhaps take a read of my widget toolkit round-up when it's done.

It's a multiple question scenario most likely, but I'll throw it out and see what people can help with =)
I'm using VS Code, and I'm trying to from kivy.properties import StringProperty and it's claiming that it doesn't exist... is this a parse issue with my linter or am I doing something wrong?

For clarity: I have no issues using other modules in Kivy except when I import things from kivy.properties

unfortunately, they don't seem to have a setup guide for vscode, and everything i can google just comes back with support for kv files

valid sage Aug 2, 2018, 3:59 PM

#

I'm not having any issues with the kv files themselves, there's a kvlang extension for vscode and it seems to work great. I'm going to assume for now that maybe it works like pysal and just throws errors sometimes due to parsing issues with the linter... I'll operate on the assumption that the import is working fine and the bug is actually a false positive. I'll check back in when I figure out the real error I guess. Thanks for the link @kind kraken it somewhat confirmed my original suspicion.

valid sage Aug 2, 2018, 5:23 PM

#

Alright, I'm convinced the import failure is a false positive, but I'm having a separate issue now. I have a Label that I'm updating dynamically through a variable, text: root.var_name and updating that variable in the python side of the script using a function

def update_variable(self,var_text):
    self.var_name = var_text
    return

It seems to be updating properly when called unless code comes after the update function, in which case my gui becomes unresponsive until the code finishes running. Is there something I'm supposed to be doing to keep the main window properly active while the program operates in the background?

obsidian lance Aug 2, 2018, 7:09 PM

@valid sage at least ... kivy + python2 work done (it was).... kivy + python3 fail always except case when you start kivy application from source code... kivy + python3 = head pain ... no exe , no apk etc... only run from source. Keep it in mind when you will choose the way

#

if you planned distribute your kivy.org app to other users... just create dummy with one button which will play sound, and try make worked exe, apk etc.... 😉 and feel the flow)

#

i never seen even one worked kivy app builded from python3 code to exe, apk etc... looks like this impossible ...only python2. And words on official kivy.org site about ... python3 now supported anime ... just fake/lie

obsidian lance Aug 2, 2018, 7:18 PM

yep... few years ago i spend two months to learn/read tutorital kivy , then 2 weeks to create app , and then two weeks to trying make at least exe, then apk.... and it was fail 100%.... two months + in trash

#

after few years i time to time try build from python3 again... and.... still no result... and no one can from usual mortals... but python2 is possible... i saw few games and apps.... that test it at least you will need download source and replace all print x to print(x) etc, that run from source under python3

#

@valid sage why you choose python for gui app development?

You should be prepared to step outside of your frontend web comfort zone

#

It's worth understanding that frontend development is very different from application or backend development in any sense

#

You just can't write things in the same manner. That's how you end up with the issues the node community faces with npm.

You should consider whether what you need to be writing is a native interface at all

#

Maybe you should write a webapp and just open a browser on localhost

valid sage Aug 2, 2018, 9:20 PM

#

@fallen oxide for the project in question, the app needs to be fully portable and have no true installer or dependencies. It's destined to run purely on Windows and the users will not be comfortable with command line. I'm very open to suggestions, Kivy was chosen because it simply made the most sense to me up front.

obsidian lance Aug 2, 2018, 9:20 PM

#

web app sounds good, lot of problems will be far from you... if web allow realize your idea

fallen oxide Aug 2, 2018, 9:20 PM

#

I would go with Qt and Nuitka

#

Nuitka will allow you to compile your entire application into a native executable, without the overhead of bundling the Python interpreter

#

Whether it supports Pyside2 is another question, though

#

Also, Qt has licensing fees

obsidian lance Aug 2, 2018, 9:22 PM

#

will be wait results about kivy build at least exe @valid sage
need read about Nuitka

fallen oxide Aug 2, 2018, 9:22 PM

vital ravine Aug 2, 2018, 10:07 PM

#

I have a pyqt question that I hope anyone can help me with.
How do I make callbacks globally accessible?
I have two GUI classes that need access to the same callbacks created in a different module.
When I instance the callback-class, they have different signatures.

#

I have a callback class that fires off signals when the host-app is saving/loading files.
I need two separate GUI modules to read these same signals, without creating additional callbacks.

fallen oxide Aug 2, 2018, 10:29 PM

#

It sounds like you have a class dealing with those callbacks

#

You could just create an instance of that class in the same module and import that instead

vital ravine Aug 2, 2018, 10:31 PM

#

Yeh, but for some reason it doesn't use the same signals. If I print the instanced signals, they have different signatures, rather than reusing those already created from the first class instance.

#

https://paste.pythondiscord.com/fureciwugu.py
I use the instance created in module1 to fire off a signal, expecting it to trigger the test-print command in both modules. However, it only fires in the one that fired it.

#

whops, ignore that the bottom class is named wrong.

button.config(command=lambda: callback)
button.config(command=callback)```

charred thunder Aug 4, 2018, 8:48 AM

in that case, there isn't a difference. lambdas would be more suitable if you need to pass arguments to a command for example

Hello, i just installed the curses module and whenever i use a program that has the variables curses.initscr and sys.stdout_.fileno in it, it just doesn't work while it's actually part of the curses module :

Traceback (most recent call last):
File "C:/Users/Merrolin/AppData/Local/Programs/Python/Python37/TEST2.py", line 4, in <module>
s = curses.initscr()
File "C:\Users\Merrolin\AppData\Local\Programs\Python\Python37\lib\curses__init.py", line 30, in initscr
fd=sys.stdout_.fileno())
AttributeError: 'NoneType' object has no attribute 'fileno'

#

Can someone help me out with this one ?

#

apparently it doesnt work on windows

#

oh fuck

#

While curses is most widely used in the Unix environment, versions are available for Windows, DOS, and possibly other systems as well. This extension module is designed to match the API of ncurses, an open-source curses library hosted on Linux and the BSD variants of Unix.```

#

you can probably find a version that works on windows i guess

odd hamlet Aug 5, 2018, 1:31 AM

#

why would you use curses on windows?

sudden coral Aug 5, 2018, 1:31 AM

#

lucy suggested a curses wheel file and I helped him install it

odd hamlet Aug 5, 2018, 1:32 AM

#

a curses wheel file for what purpose

digital rose Aug 5, 2018, 1:32 AM

#

i mean, the file that i got has "win" in it, so i suppose it's already windows compatible ?

odd hamlet Aug 5, 2018, 1:32 AM

#

na that means you can install on win

#

not you can use it

digital rose Aug 5, 2018, 1:32 AM

#

o h

odd hamlet Aug 5, 2018, 1:32 AM

#

anyway

#

why curses on windows

digital rose Aug 5, 2018, 1:33 AM

#

because i thought that's all there was to have graphics on a terminal for python ?

#

the gramphics

odd hamlet Aug 5, 2018, 1:34 AM

#

i assume it is but graphics and cmd arent that much of friends

#

ive never seen a working terminal graphic on a windows system

digital rose Aug 5, 2018, 1:34 AM

#

no but i mean, i was trying to get a snake game to work on the terminal, to see the inner workings and etc

#

and it used the curses module

#

so should i get rid of it and get an equivalent for windows ?

odd hamlet Aug 5, 2018, 1:35 AM

#

i dont know of an equivalent for windows

sudden coral Aug 5, 2018, 1:35 AM

#

that wheel should be the equivalent

#

it's based on pdcurses

#

which states it supports windows

odd hamlet Aug 5, 2018, 1:36 AM

#

i think the terminal usage on windows isnt really high enough to offer an alternative for curses on windows

digital rose Aug 5, 2018, 1:36 AM

#

then what should i do ?

odd hamlet Aug 5, 2018, 1:37 AM

#

i assume you could get into some real graphics framework or even the pygame lib (although you should never use python for bigger games)

#

pygame works on windows

#

and i think on all other popular platforms too

digital rose Aug 5, 2018, 1:38 AM

#

well, i'll see

#

but i just wanted to make a simple program, yknow, that looked like one of these early commodore 64 games with ASCII art as graphics ?

odd hamlet Aug 5, 2018, 1:40 AM

#

i mean you can do ASCII graphics in python

#

i wouldnt be surprised if there would be a framework for that actually

#

and due to it being pure ascii it would even work on windows

sudden coral Aug 5, 2018, 1:41 AM

#

there's asciimatics

digital rose Aug 5, 2018, 1:41 AM

#

is it compatible with windows this time

sudden coral Aug 5, 2018, 1:41 AM

#

but like I said PDcurses is a thing just not sure why it didnt work out for you

digital rose Aug 5, 2018, 1:42 AM

#

it's pretty weird indeed

sudden coral Aug 5, 2018, 1:42 AM

#

yeah, it says it works on windows

digital rose Aug 5, 2018, 1:42 AM

which is the best for GUI? I tried Gooey and it's not showing TextCtrl.

#

Tkinter?

marble totem Aug 5, 2018, 1:03 PM

#

Tkinter or, if you like QT, PyQT5 or PySide2

fallen oxide Aug 5, 2018, 1:04 PM

#

I always recommend Pyside2

#

It's fully-featured and not all that hard, and I recommend it over PyQt5 because PySide2 is the official Qt for Python

#

it has better support, better docs

#

generally an all-around good idea ™

marble totem Aug 5, 2018, 1:06 PM

upbeat spear Aug 6, 2018, 12:24 PM

#

Do you need anything on the side to get PySide2 to be fully functioning as a GUI? Ive been trying to learn to do GUI, and I've done TKinter, but it hasn't really met the kind of functionality expectations I have wanted. Then again I might not be far enough in programming or Python in general to do some things I am hoping for

#

I have converted to PySide2 and its far superior to tkinter. But one thing bothers me... the distinct lack of signals. It seems you have to subclass everything just to get a QObject to emit a decent signal.

#

Want a signal from QApplication when it resizes? Nope, gotta subclass it first. EDIT: Actually QMainWindow... but you get the idea

@odd mural Best 2D library for python?

wind birch Aug 7, 2018, 3:18 AM

#

@odd mural PyGame is, but python games are pretty terrible. you can do good things with the language, but they're both not easily portable and pygame seems to have lacking documentation from what I've heard people say. Kivvy might also be a shot because it exposes OpenGL bindings.

@drifting sundial this is unfortunately only a solution for programs that you control/develop, and I don't think this will have any effect on GTK warnings at all since I don't believe they originate from python 🤔

It captures any warnings thrown during execution

Unless you're not using a library

to my knowledge GTK bindings throw warnings through their own whatever ways in C, not through pythons warnings module, so this filter won't be able to catch it

QT question, anyone got a suggestion on how to ignore a mouseMoveEvent/mousePress when using a QSizeGrip widget? I have a borderless window which is moved when left-mouse is pressed and moved while held down. Which is what happens when using the QSizeGrip, so it gets a bit confused poor thing.

vital ravine Aug 8, 2018, 9:10 PM

#

Okay, think I solved it myself, by separating them into two separate widgets, so they don't share the same click-events. Just made a blank-dummy widget that I stacked between the overlapping QSizeGrip-widget and interface-widgets.

Sounds a bit dirty, but seems to work.

@midnight scroll I’ll read your reply when I get home from work

charred thunder Aug 13, 2018, 3:41 AM

@untold granite the best way to do that i assume would be to create a function that constructs the widget given a master. i.e,

def create_special_treeview(master):
    # ... do stuff ...
    return treeview  # replace with actual treeview object obviously.

and then you can pass your different frames as an argument to the function when you need to make/copy it. it won't act like a copy by reference, so modifications to one will not apply to the other, but what i provided gives you a general idea; you can't directly copy a widget from one master to another, you've gotta create multiple.

untold granite Aug 13, 2018, 6:52 AM

#

why can I not pass variables into button pushes!

#

It's incredibly frustrating! I cannot create any frames outside of my init it feels like!

#

I just had to use lambda ty for listening to my rants.

charred thunder Aug 13, 2018, 7:02 AM

you technically can pass variables into button pushes, using functools.partial functions. however, in most cases, lambda will suffice.

digital rose Aug 13, 2018, 11:05 AM

@midnight scroll The user doesn't select their files the files are embedded in the program so file dialog wouldn't work

that menu is just a list created by looping through a folder in the program that only holds files meant for the program

midnight scroll Aug 14, 2018, 11:23 AM

#

@digital rose Can you explain your target a bit more

#

So you have a checklist in tkinter?

#

I need to know a bit more

#

You could loop over menu_btn.menu.index and get all buttons

#

or you could save all the variables you put into the buttons in a dict or list, and check if they are set. If so, get the content from the corresponding button

hm, I'm doing some tkinter stuff and weirdly

self.canv.itemconfig(self.gfx, state='hidden')

works perfectly and hides self.gfx but the suggested solutions for displaying hidden items again:

self.canv.itemconfig(self.gfx, state='normal')
self.canv.itemconfig(self.gfx, state=tk.NORMAL)

both do not work (the canvas items stay hidden). Does anyone know off the top of their heads what's going on?

Hi, I have got a question regarding pygame. I use piVirtualWire to send rf messages to my arduino and try to read ps4 controller input and send messages from these readings. PiVirtualWire itself is perfectly fine. I have a script, which sends 10/10 messages correctly. When I try to implement a simple sending in the main loop of pygame, it does not work anymore. Making a while true loop without pygame works however. I hope you can help me. Shall I send my script as a message or as a file?

#

#!/usr/bin/python3

import sys, pygame, os
import time
import piVirtualWire.piVirtualWire as piVirtualWire
import pigpio

pygame.init()
size = [500, 700]
screen = pygame.display.set_mode(size)

start_time = time.time()
# os.system('sudo /home/pi/PIGPIO/pigpiod')
pi = pigpio.pi()
tx = piVirtualWire.tx(pi, 4, 1000)

while 1:

    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            tx.cancel()
            pi.stop()
            pygame.quit()
            sys.exit()

    if time.time() - start_time > 0.5:
        start_time = time.time()
        tx.put("12")
        print("Sending")
        tx.waitForReady()

    pygame.display.flip()```

yeah sorry haha

charred thunder Aug 15, 2018, 1:25 PM

#

so you're sending "12" every half a second from what i can see, right?

forest island Aug 15, 2018, 1:26 PM

#

yes, but I dont receive anything. And after I run the script, my simple transmit script also does not work anymore. Then I have to restart to make it work again.

charred thunder Aug 15, 2018, 1:27 PM

#

what do you see in the console of your script if you put print("penis") in your loop? debug prints are the way to go :D

forest island Aug 15, 2018, 1:27 PM

#

Well if I run the code like above, I already see "Sending" every half a second

charred thunder Aug 15, 2018, 1:28 PM

#

oh I see

forest island Aug 15, 2018, 1:29 PM

#

Also tried evdev for gamepad input. Running it in a while loop ther works. But evdev is not very responsive

charred thunder Aug 15, 2018, 1:29 PM

#

could you send an example of some working tx code?

forest island Aug 15, 2018, 1:30 PM

#

import piVirtualWire.piVirtualWire as piVirtualWire
import time
import pigpio

pi = pigpio.pi()
tx = piVirtualWire.tx(pi, 4, 1000)

msg = "42"

tx.put(msg)
tx.waitForReady()

tx.cancel()
pi.stop()```

#

This is from piVirtualWire's github page. Works for me. My simple transmittion script is the same. Only difference, I use argv for custom input.

charred thunder Aug 15, 2018, 1:31 PM

#

the only thing i can think of is the message itself being different causing problems

forest island Aug 15, 2018, 1:32 PM

#

Wait a moment. I had a different idea to do it, which also did not work.

#

I called this script trans.py

import piVirtualWire.piVirtualWire as piVirtualWire
import time
import pigpio
import sys

def main(arg1):
    pi = pigpio.pi()
    tx = piVirtualWire.tx(pi, 4, 1000)

    tx.put(str(arg1))
    print("Sending: "+str(arg1))
    tx.waitForReady()

    tx.cancel()
    pi.stop()

if __name__ == "__main__":
    main(sys.argv[1])```

#

Then i did

#

import trans```
...
```python
if time.time() - start_time > 0.5:
        start_time = time.time()
        trans.main(2)```
in the first script I posted.

charred thunder Aug 15, 2018, 1:38 PM

hmm

#

i'm honestly not sure at this point, then

forest island Aug 15, 2018, 1:39 PM

#

Wait one more thing. I run it from a desktop shortcut on my rpi. Does this make any difference? I mean a .desktop file

#

#

#

might be a long shot but try putting the joypad input in a thread, it feels like a blocking I/O issue

drifting sundial Aug 17, 2018, 4:29 AM

#

@forest island I know Pygame has that functionality

#

It was pretty trivial for me to implement a few years back in a game

#

It just generates input events

#

Underneath, it uses SDL

#

So you could use Pygame directly, or write for SDL, which I'm pretty sure has Python bindings

@fallen oxide whats the difference

between pyside2 and pyqt

fallen oxide Aug 21, 2018, 11:35 AM

#

pyside2 is the official distribution

#

pyqt is third-party

#

other than that, I have no idea

digital rose Aug 21, 2018, 11:35 AM

#

oh ok

placid tapir Aug 21, 2018, 1:54 PM

#

Isn’t pyside2 / pyQT more limited in its aesthetic potential?
I’ve yet to see a pyQT app I thought looked appealing. Maybe well designed layout but the overall look is basically “slightly modified native windows”

#

Kivy gives more control over aesthetics that I’ve seen

#

Granted from my limited exposure to GUI

fallen oxide Aug 21, 2018, 1:55 PM

#

Qt is designed to look native

#

And that's really what you want

#

This isn't the 90s, making your application stand out that much is just annoying most of the time

#

That said, you can set up themes regardless

placid tapir Aug 21, 2018, 2:13 PM

#

themes like mild color changes or can I have background images /custom buttons / modified borders / minimize/windowed-fullscreen/close buttons etc

if your plotting lib outputs an image, you can pretty easily use Qt

timber vale Aug 22, 2018, 4:46 PM

it's matplotlib, ideally

tawny gust Aug 22, 2018, 4:47 PM

Seaborn is a nice wrapper around matplotlib, it's pretty nice too

But yea, you should be able to use Qt

how come this runs the command for the menu button upon creation of the menu button and not when the user selects the button

#

okay so i've found out its because im invoking the function not just passing it

Guys any video series for tkinter

Pls rell

#

Hey, in tkinter, I have an image attatched to a label, but when I display this label, the window won't show up. I have other buttons and stuff, and without the image label they display correctly but when I add the image label the window never appears. Is it because I'm converting a PIL image to tkinter?

#

actually regular label does the same thing

#

and canvas

obsidian lance Aug 26, 2018, 7:39 PM

#

@meager mulch tkinter so old , that video should be at least on videotape )))

dense lance Aug 26, 2018, 8:53 PM

#

so no

crimson spruce Aug 26, 2018, 9:58 PM

#

@dense lance, there's a special class in PIL/Pillow for a Tkinter-compatible image. Are you using that?

dense lance Aug 26, 2018, 9:59 PM

#

yes. My latest problem concerning this is in #help-grapes

crimson spruce Aug 26, 2018, 10:04 PM

#

@dense lance, I wrote an image viewer awhile back that you might find helpful... the code isn't great, but it uses Pillow, since I needed to zoom-in/out.
https://github.com/DeflatedPickle/Quiver/blob/master/image_viewer.py

obsidian lance Aug 26, 2018, 10:12 PM

#

what benefit uses Pillow in your case?@crimson spruce

crimson spruce Aug 26, 2018, 10:12 PM

#

I think it was the zooming-in/out. I haven't messed with it for awhile but I don't think normal Tk images are that advanced.

obsidian lance Aug 26, 2018, 10:13 PM

#

it will crossplatform?

crimson spruce Aug 26, 2018, 10:14 PM

#

It probably will... I don't advise using the program, but it should work for multiple platforms. I've never had an OSX VM to test. 🤷

obsidian lance Aug 26, 2018, 10:16 PM

#

as i remember , tkinter only can display image in widget... but it looks not especially good and flexible. For zooming etc try look at pmw(python mega wigdet) or any tkinter frameworks.

has anyone used the page python gui builder thing before or is it easier/ more efficient to write it out

crimson spruce Aug 26, 2018, 10:17 PM

#

@obsidian lance, don't even that with me... I know what to do, I've been using Tkinter/Tk for just about 4 years now. 🤷

What I do here, is I display it on a canvas and use Pillow to resize it when the user scrolls in or out.

4 years huh

u wanna hop on voice or somthing im uncontrollably lost

If you're looking for a quick to develop GUI, Tkinter is great. If you want something that'll be faster and look slightly better (only slightly 'cause Tkinter does have that TTK module), I'd recommend wxPheonix. If you want more configuration, I'd recommend PySide/PyQt.

Though, over-all, I don't recommend GUI development with Python. Unless you're using a faster interpreter like PyPy, they can really slow down.

#

I like to think I'm a decent source for UI questions... I am kinda writing a book comparing them all.

warm heart Aug 26, 2018, 10:22 PM

#

what should i do instead of using python. My script is in python and i want to be able to build it all into a no downloads exe that anyone could use

crimson spruce Aug 26, 2018, 10:23 PM

#

You could make a CLI interface for it, then you could query it from any other language.

obsidian lance Aug 26, 2018, 10:23 PM

#

i remember shitty , places when i touch wxPheonix , becase on windows and linux the gui builder process is different(windows add back zaxis, linux addon front zaxis, for new button etc). and scrolling code for win/linux is different.... not fully crossplatformed... close to head pain... but support gtk default

#

if your linux system is dark then wxphenix app was dark too... it looks not bad

crimson spruce Aug 26, 2018, 10:24 PM

#

All I will say, is that with using any other toolkit, I always miss the ease of creating UIs with Tkinter.

warm heart Aug 26, 2018, 10:24 PM

#

my thing is cli rn but im working with doctors and they dont like scary terminals

obsidian lance Aug 26, 2018, 10:25 PM

#

why you not use html + javascript? if your doctor scary cli?

crimson spruce Aug 26, 2018, 10:25 PM

#

Then you should be able to pass in command-line arguments from any other language and do the UI in that other language.

obsidian lance Aug 26, 2018, 10:25 PM

I've been using SWT and Kotlin the past couple days... it's no Tkinter in terms of placing widgets (to the point I want to write a wrapper), but its' expanded feature set and actual wrapper of OS widgets and features far out weighs that.

#

but if its cross language will i be able to build everything all the packages everything into a no extra software downlad exe

#

i want to use tkinter

crimson spruce Aug 26, 2018, 10:27 PM

#

You'd build the Python script, then query the built version with the other language.

warm heart Aug 26, 2018, 10:28 PM

#

it doesnt have to be fancy and its not too complex the most complex thing i want is a scrolllist with checkboxes and their labels

#

can i do that with tkinter

crimson spruce Aug 26, 2018, 10:29 PM

#

It's a shame I stopped writing my Tkinter guide, would have helped here... I can provide some links on where to get started and an example I wrote for my widget toolkit comparison if you want?

And of course you can do that!

simple is html/js(face) and python(backside) to work with db etc... but i don't know why you use python ... the reason should be something like numpy etc using... for math js worst then python

i deleted all the .htmls it could possibly be pulling from and yet still somwhoe it still run

#

i get it when ur code dosent run from an error but im puposley trying to get it to fail it and wont

#

i dont understand

#

when i start eel then in my browser i go to localhost:8000/main.html

#

its there

#

but idk where

obsidian lance Aug 27, 2018, 1:40 AM

#

@warm heart ha, eel start work when you run python script... not html.... run python , then html will opened automatically, or will empty html + js without python back

warm heart Aug 27, 2018, 1:41 AM

#

nononono ur getting me wrong

#

i run the python

obsidian lance Aug 27, 2018, 1:41 AM

you can pack eel as executable uses pyinstaller , but need chrome/chromium on the board

warm heart Aug 27, 2018, 1:41 AM

with abosultely no .html anywhere to be seen

#

and somhow it finds an html on my localhost

Okay, I made a project with flask, I need a non-web app gui

#

most people hate tkinter which is what I used in the past. Give me your recommendations everyone

#

I'm sure I could still use flask but it takes so much longer and its for personal use

#

as a sort of app rather than a website

I’ve been told pyside2 Qt is the way to go, but don’t have much experience myself

hey im trying to write a small program that gets a filename through pyside2 by using getOpenFileName() once and then closing the gui. im not that experienced with guis and doing this because manually typing in a path cli sucks for an end user. ive been looking through stackexchange etc but havent had much luck

Anyone around to answer a few questions about PyQt/PySide? Specifically around resource files and mouse events for frameless windows.
