Hi to all! Please help me with Kivy TreeView:

#

class DBApp(App):
    def build(self):
        #Main layout
        bl=BoxLayout(orientation='vertical', padding=30, spacing=10, size=[500,500])
        #Folder treeView
        Tree_Box=BoxLayout(orientation='vertical', spacing=10)
        tv = TreeView(root_options=dict(text='Tree One'), hide_root=True, indent_level=4)
        tv.size_hint = 1, None
        tv.bind(minimum_height=tv.setter('height'))
        for x in range(20):
            lvl_1=tv.add_node(TreeViewLabel(text=str(x), is_open=False))
            for n in range(5):
                nn=str(x)+'-'+str(n)
                tv.add_node(TreeViewLabel(text=nn), lvl_1)
        sv = ScrollView(pos=(0, 0), bar_width=15, scroll_type=['bars', 'content'], scroll_wheel_distance=50)
        sv.add_widget(tv)
        Tree_Box.add_widget(sv)
        Tree_Box.add_widget(Label(text='*Please select destination folder', size_hint=[1, None], size=[100,40]))
        tv.bind(on_press=self.select_node)
        #Uploading file local path
        Upload_Box=BoxLayout(size_hint=[1, None], size=[100, 40], spacing=10)
        Upload_Box.add_widget(TextInput())
        btn=Button(text='Upload', size_hint=[None, 1], size=[100,40])
        Upload_Box.add_widget(btn)
        bl.add_widget(Tree_Box)
        bl.add_widget(Upload_Box)
        return bl

    def select_node(self, node):
        '''Select a node in the tree.
                '''
        if node.no_selection:
            return
        if self._selected_node:
            self._selected_node.is_selected = False
        node.is_selected = True
        self._selected_node = node
        print(node)


if __name__ == "__main__":
    DBApp().run()

#

How can I make sure that the name of the selected node in TreeView is written in the console or TextInput?

Hello friends

#

I'm trying to do this thing where people use discord chat to play a game (specifically portal 2). For the keyboard presses, I'm using pyautogui, but it doesn't seem to work inside portal 2. It works in any other place (I tested it inside a browser game (krunker.io) ), but just not inside portal 2

#

So do y'all know any API that you think doesn't encounter this problem or the reason why it can't be done?

#

please ping me in your response

Hey, how would I go about adding new items to a Listbox at runtime? Since I normally have to do list = Listbox() which I don't believe I add at runtime.

#

Never mind figured it out, I use the .insert thingy.

zealous schooner Apr 29, 2020, 10:44 AM

#

is it possible to do the entry bit of this gui?

📎 unknown.png

#

using tkinter

#

with grid() if possible

clear nexus Apr 29, 2020, 11:09 AM

#

yes

#

        -Make button-
       button2 = tk.Button(self, text= "Click to calculate", command = godfunc)
       button2.grid(row=1, column=0) 
       
-Make entry box-
        Area_entry = tk.Entry(self, width = 5 )
        Area_entry.grid(row=0,  column=1 )
    
-disaply image-
    load = Image.open(pic) # set in file directory 
    render = ImageTk.PhotoImage(load)
    
    
    img = tk.Label(self, image=render)
    
    img.image = render
    img.place(x=0, y=0)
    img.pack()
    ```som examples @zealous schooner

#

to get the value of the entry box. you can do something like
a = Area_entry.get()

#

remeber to convert it to what value you need it if it be a string,int, float etc.

zealous schooner Apr 29, 2020, 11:19 AM

#

thanks

#

checking it out ill give an update in a moment

clear nexus Apr 29, 2020, 11:21 AM

#

where i have "self", you need to put your root to your window for what you have called it. You should have somthing like root = tk.Tk() so this would be button2 = tk.Button(root , text= "Click to calculate", command = godfunc)

#

for image you need ```from PIL import Image

zealous schooner Apr 29, 2020, 11:32 AM

#

@clear nexus it looks like the image overlaps the button and the entry, i commented out the img.place() line and the button and entry are not positioned the way i asked how..

clear nexus Apr 29, 2020, 11:33 AM

#

show me your code

#

if you see on the bottom it says pack() you need to change it to grid

zealous schooner Apr 29, 2020, 11:56 AM

#

@clear nexus

# -Make button-
button2 = Button(root, text="TEMP")
button2.grid(row=1, column=0)

# -Make entry box-
Area_entry = Entry(root, width=5)
Area_entry.grid(row=0, column=1)

# -display image-

url = # THE URL #
load = url_to_image(url)
render = ImageTk.PhotoImage(load)

img = Label(root, image=render)

img.image = render
img.place(x=0, y=0)
img.grid()

root.mainloop()

clear nexus Apr 29, 2020, 12:26 PM

#

you need to give the image a grid spacee

#

img.grid(row=2, column=0)

zealous schooner Apr 29, 2020, 12:30 PM

#

idc about the image rn

#

the entry and the button doesn't look like the image i sent

clear nexus Apr 29, 2020, 12:31 PM

#

no you have to do that yourself

#

i just gave you an example

#

on how you set it up

#

im not doing that for you sorry

zealous schooner Apr 29, 2020, 12:31 PM

#

the example is wrong

clear nexus Apr 29, 2020, 12:32 PM

#

no that is how you do it. You need to set it up where you want it

zealous schooner Apr 29, 2020, 12:32 PM

#

the example does not show me how i put two elements on the same column

#

like that

📎 unknown.png

clear nexus Apr 29, 2020, 12:34 PM

#

you should read up how tkinter work and watch some youtube tutorials, you clearly have done no research if you cant figure that out. and no you dont want it on the same column you want it on the same row.... do to so you have one that is row=1, column = 0 and the other row =1 , column = 1

zealous schooner Apr 29, 2020, 12:36 PM

#

what the fuck are you talking about

clear nexus Apr 29, 2020, 12:36 PM

#

what are you not understanding?

zealous schooner Apr 29, 2020, 12:37 PM

clear nexus Apr 29, 2020, 12:37 PM

#

thats now how tkinter grid works... you'd know if youd google it

zealous schooner Apr 29, 2020, 12:37 PM

#

bruh

#

if you wanna prove your point google it yourself and find me a solution

#

you really think the first thing i do is ask a fucking discord server?

#

i come here the get solutions not to get stupid example which doesn't even work

if you cant help don't even bother

zealous schooner Apr 29, 2020, 12:54 PM

#

is it impossible to have an offset grid row

#

?

lucid wraith Apr 29, 2020, 1:14 PM

#

@zealous schooner when you grid button3, add the keyword argument columnspan=2

zealous schooner Apr 29, 2020, 1:14 PM

#

oh right

lucid wraith Apr 29, 2020, 1:20 PM

#

Alternatively, you can put button4 and button5 inside a Frame, which you grid into a single row/column.

hello, I started with tkinter and manage to stuff for my needs, but damn it's ugly :D
Is there a way to beautify things without too much effort?

📎 unknown.png

clear nexus Apr 29, 2020, 7:58 PM

#

@eternal lake not really, the best you can do is change background color i think to make it look a little better on some of the figures. But stylewise there's not much to do with tkinter.

#

you can add background color to the buttons and lables for me it made it look a little nicer

#

i like my buttons with green and white text

#

can mix match like speedAndPitch = tk.Button(self, text="Adjust speed/pitch",height = 2, width = 15,command=empty, bg='green', fg='white', font=('helvetica', 30, 'bold'))

tribal path Apr 29, 2020, 8:13 PM

there is ttk for some themed/style stuff - but beyond that not much movement. tcl is a pretty old ui framework

How do u multi-line flush on windows

#

please somebody help, i'm begging

#

Can't figure this out for 2 days straight

#

Help channels gets ignored

#

Cuz it's a very annoying issue

#

I tried out PDcurses

#

I get Redirection is not supported

#

cuz its on console in pycharm

#

I can't get WConio installed for some reason

#

http://newcenturycomputers.net/projects/wconio.html

#

So those are almost exclusively the only tools to do this with windows

#

there's also another possiblity with:

#

https://github.com/Yinzo/reprint

GitHub

Yinzo/reprint

a Python 2/3 module for binding variables and refreshing multi-line output in terminal. - Yinzo/reprint

#

but i can't get that working for some reason

#

The only last possibility is to basically use the Windows Console API

#

but i don't know how to make that work with python

tribal path Apr 29, 2020, 9:56 PM

#

afaik the issue here is not just windows & curses, but that pycharms console doesnt really handle ansi codes.

is just running cls not an option?

digital rose Apr 29, 2020, 11:00 PM

how do i run cls?

regarding tkinter does anyone know how to assign say a label with a tag and then edit the label based on the find_withtag? I'm struggling to figure it out

thorny spruce Apr 30, 2020, 3:31 PM

#

Is that with a Canvas?

sturdy reef Apr 30, 2020, 3:39 PM

#

yeah

#

@thorny spruce so I tried label.bindtags(tagID)

#

then canvas.itemconfigure(canvas.find_withtag(tagID), bg='red')

thorny spruce Apr 30, 2020, 3:45 PM

#

I believe those are two different sets of tags

sturdy reef Apr 30, 2020, 3:47 PM

#

hmm I see

thorny spruce Apr 30, 2020, 3:52 PM

#

@sturdy reef So if you wanted the actual label object you can do

import tkinter as tk

def on_click(event):
    canvas: tk.Canvas = event.widget
    item_id = canvas.find_withtag('my_label')
    widget_name = canvas.itemcget(item_id, 'window')
    label = canvas.nametowidget(widget_name)
    label.config(text=(event.x, event.y))

def main():
    root = tk.Tk()
    canvas = tk.Canvas()
    canvas.pack()

    lbl = tk.Label(root, text=(0, 0))
    canvas.create_window((100, 100), window=lbl, tag='my_label')
    canvas.bind('<Button-1>', on_click)

    root.mainloop()

main()```

#

If you just wanted to configure the options that create_window provides then just

def on_click(event):
    canvas: tk.Canvas = event.widget
    item_id = canvas.find_withtag('my_label')
    canvas.itemconfigure(item_id, width=100)```

#

Is this what you were after?

sturdy reef Apr 30, 2020, 4:02 PM

#

thank you. I'm still trying to break it down in my head I'm still a little new to python but this is very helpful

thorny spruce Apr 30, 2020, 4:02 PM

#

Yea, I would have thought there was an easier way to get the label that was added through the canvas but either there isn't or I can't see it

#

If you are able to just store your label objects it would be must easier than having to go through the canvas

sturdy reef Apr 30, 2020, 4:11 PM

#

yeah problem is there is a dynamic amount so I'm trying to create a function for it. so when you are adding via the canvas I see you are doing canvas.create_window but when I create a label i do:

label = tk.Label(root, text="testing", bg='blue') label.place(relx=0, rely=0, relwidth=1, relheight=1) label.update()

so this in a function obviously just creates a bunch of widgets called label I tried passing a name through the function but it didnt work. so my idea was to pass an id and then set it with an id

thorny spruce Apr 30, 2020, 4:12 PM

#

place would just put it on top of the canvas, it wouldn't actually add it to the canvas

#

If you are creating multiple dynamically then try keeping track of them either in a list or dictionary

sturdy reef Apr 30, 2020, 4:13 PM

#

so if I have them in a list how would I then edit attributes like say the text

thorny spruce Apr 30, 2020, 4:14 PM

#

You'd index it out of you list and then configure it

#

my_label = list_of_labels[index_of_label_you_want]
my_label.config(bg='yellow')```

sturdy reef Apr 30, 2020, 4:15 PM

#

okay I see I will give it a try thanks for your help.

#

wow okay thanks for that it works like a charm! I didn't realize it was just .item list .config as I tried a list before too. I think I'm too used to c# showing all available functions aha

thorny spruce Apr 30, 2020, 4:20 PM

#

Depending on your IDE it should show what you can do

digital rose Apr 30, 2020, 8:27 PM

#

os.system('cls') does not work

#

it just gives some sort of character

#

import os
import sys
import time


def increment(i):
    return i+1

def multiply(i):
    return i*2

for i in range(5):

    "chocolates eaten {chocolate}\r\n".format(
        candies=increment(i),
        chocolate=multiply(i)
    ))

    os.system('cls')
    time.sleep(0.5)

Hey anyone know this issue with kivy [CRITICAL] [Clock ] Warning, too much iteration done before the next frame. Check your code, or increase the Clock.max_iteration attribute

#

Tried turning up the max_iteration but still no difference

sharp plover May 2, 2020, 9:52 AM

#

@rain rock I've run into this, myself, but I can't remember off the top of my head what you need to do to fix it. It'll be more on your end than kivy's.

#

You might have Properties in your kv that are bound to each other. One looks at the other, which looks back and so on.

#

    id: foo
    text: bar.text
Label:
    id: bar
    text: foo.text```

#

Something like that.

#

Maybe.

@scarlet ibex Well you just made it be like that so what if when teh widget dissapers it moves the textbox and the days whatever you are doing up to the rest of them? (No tkinter expert)

scarlet ibex May 2, 2020, 1:34 PM

#

@last gulch yes thats what im trying to do

#

i want to move those 2 widgets up

last gulch May 2, 2020, 1:35 PM

#

Not sure what tkinter uses but tried using .place() instead of .pack()? you can freely lay them aroudn the frame like with kivy

scarlet ibex May 2, 2020, 2:07 PM

#

if anyone gets this problem i spent hours on a solution so here you go:

tmp = tk.Frame(self.parent, width=1, height=1, borderwidth=0, highlightthickness=0)
tmp.pack()
self.controller.update_idletasks()
tmp.destroy()

Where self.parent is the frame you want to hide, and self.controller is the root/master
this will put a little frame and update the first frame to match the size of the frame inside it, then deletes the little frame.
put this code after you delete the widgets in the frame.

Hi, can I ask what would you use for serious desktop application with modern & clear look? I have tried Kivy, but it's super problematic to setup and package final project and also documentation isn't good. Qt is commercial and other frameworks seems abandoded.

@empty needle Alot of apps now use electron

#

it basically allows you to take websites and make them into applications

#

Discord is an example of an electron app

#

its the same on the app as the website because electron is essentially a browser just a lil diffrent

hollow mist May 5, 2020, 6:12 PM

#

you can run flask inside an electron container

#

with pyshell for js

empty needle May 5, 2020, 6:14 PM

#

Is it then possible to get an exe in the finals? For example What if I would want to make music player... ?

hollow mist May 5, 2020, 6:16 PM

#

Python isn't a very good fit for that and using Electron for that is overkill

#

in that case you're better off using C# or Go

#

Or just concede to the fact that most people use streaming these days

empty needle May 5, 2020, 6:34 PM

#

in that case you're better off using C# or Go
I hoped there would be any good option to stay with Python, but I think I will try the C# with .net core that should be multiplatform

If your application hangs then you have a blocking operation going on

What do you mean by async button function?

zealous abyss May 5, 2020, 8:55 PM

#

as in I press the button, some function does stuff in the background and eventually finishes

#

unless I was mistaken, it looked like when I ran it, the program froze while it waited for the function to execute

#

it crashed about 5 seconds later

spiral crescent May 5, 2020, 8:56 PM

#

That function is a callback function which is executed when you press the button, I'd assume if your call isn't a blocking call then you can listen to an event your process, started by the function, emits.

#

Signals and Slots

zealous abyss May 5, 2020, 8:59 PM

#

well, I dont necessarily need to listen for an event from the function, it just needs to run without blocking the program

spiral crescent May 5, 2020, 8:59 PM

#

Like say button press starts a process named X
Do something like X.finished.connect(function)

#

I'd assume you're using qprocess

zealous abyss May 5, 2020, 9:00 PM

#

im not

#

I must be missing something

#

when you click a button that has an attached method, it executes the method, no?
does that method block the program, or does it execute it asynchronously

#

if it blocks I can just work around that

spiral crescent May 5, 2020, 9:02 PM

#

It blocks

zealous abyss May 5, 2020, 9:02 PM

#

so, if I had a method that printed a million things, it would just stop the gui?

spiral crescent May 5, 2020, 9:03 PM

#

If the function is written in a blocking way, Yes it'll freeze the GUI.

zealous abyss May 5, 2020, 9:03 PM

#

ah

#

what does qprocess do, exactly?

spiral crescent May 5, 2020, 9:04 PM

#

Spawns a process separate from main thread

zealous abyss May 5, 2020, 9:04 PM

#

and I can use it as if it was any other multithreading api?

spiral crescent May 5, 2020, 9:07 PM

#

You use it mostly with signals, which it emits. Like when it's ready for reading stdin, when it starts, when it ends etc.

zealous abyss May 5, 2020, 9:07 PM

#

ok, ill look into that some more

#

thanks for the help!

spiral crescent May 5, 2020, 9:07 PM

You're welcome.

#

simple QThreads are enough for most tasks

#

if the callback blocks the gui thread

zealous abyss May 5, 2020, 11:00 PM

#

well, Im having some more issues with my code:
I created this QThread class

class AddAccountThread(QThread):
    def __init__(self):
        QThread.__init__(self)

    def __del__(self):
        self.wait()

    def run(self):
        print("here3")
        driver = webdriver.Firefox(executable_path = r'driver\geckodriver.exe')
        # driver.maximize_window()
        #
        # fill_in_info(driver, next_account_num)
        print("here4")

def on_account_add():
    global next_account_num
    # print("here")
    # btn.setText("hello?")
    # print("here1")
    new_thread = AddAccountThread()
    new_thread.start()
```where on_account_add() is mapped to a button
however, when I click the button, despite the method on_account_add() finishing, the AddAccountThread().start() still blocks the gui and freezes it

barren elm May 6, 2020, 3:53 AM

#

In Pyside2 can Signals and Slots only pass int and str? I am trying to emit a list and dict but it doesn't seem to like that idea.

barren elm May 6, 2020, 4:59 AM

#

Either that or the QThreading tutorial I used is bunk.

I have managed to export the output to the table widget but the problem is that it waits for me to terminate the process in the terminal for it to display the output. I want it to display while the program is running.

barren elm May 6, 2020, 7:49 PM

#

You need to use QThread. If you stop the event loop to process something the program will freeze. Threading the work behind the scenes will keep your GUI running smoothly.

#

Multi-processing can work as well. Just depends on what you are doing.

#

I could be wrong here as I am not entirely sure what you are trying to do now that i think of it.

full comet May 6, 2020, 9:58 PM

Hey All, I'm pretty new to programming. Is there anyone that could help explain what I'm doing wrong? I just want the function to load a webpage contained within the "browserBox" object. I commented which line crashes it. Code compiles fine. I know the function works fine, the button can load google in a separate browser.

from PyQt5.QtWidgets import QApplication, QMainWindow
from PyQt5.QtWebEngineWidgets import * 
from PyQt5.QtCore import * 
from PyQt5.QtGui import * 
from PyQt5.QtWidgets import * 
import sys
import webbrowser

def buttonAction():
    webbrowser.open('https://google.com') #WORKK
    #web.load(QUrl('https://google.com')) #CRASH

def window():
    app = QApplication(sys.argv)
    win = QMainWindow()
    win.setGeometry(200, 200, 774, 555)
    win.setWindowTitle("Test")

    #HTML Content Box

    browserBox = QtWidgets.QTextBrowser(win)
    browserBox.setGeometry(QtCore.QRect(150, 40, 601, 451))    
    web = QWebEngineView(browserBox)
    web.setGeometry(QtCore.QRect(0, 0, 601, 451))

    #Button Widget
    testButton = QtWidgets.QPushButton(win)
    testButton.setGeometry(QtCore.QRect(0, 20, 113, 32))
    testButton.setText("Click Me")
    testButton.clicked.connect(buttonAction)

    win.show()
    sys.exit(app.exec_())

window()```

#

also if I take web.load out of the buttonAction() function... and just placed it inside the window function. It works fine. Which is nice because it loads google inside my browserBox. However I want to click a button to have it load into the box

put your buttonAction function inside your window funciton

Technically the way you have it set up you don't even need the window function

you need the contents it just doesn't have to be in the form of a function.

No problem. PyQT5 only gets more and more complicated. One step at a time 🙂

#

As a side note your imports are redundant as well. You can delete lines 1 and 2 as you import literally everything you could possibly need in the next 4 lines.

proper glade May 7, 2020, 2:23 AM

there's a little trick in pyqt5 for condensing everything into one import:

from PyQt5.Qt import *

for the less patient :p

#

or you can put your imports into a separate file called qt.py then do import qt and access the members like qt.QApplication(...)

#

most pythonic imo

#

and if at any point you wanna switch to pyside you can just change the imports in qt.py to match

Are signals and Slots able to pass lists and dicts to a worker in a thread?

proper glade May 7, 2020, 4:11 AM

#

think so. primitive objects shouldnt pose any problem

#

whats inside the lists and dicts?

barren elm May 7, 2020, 4:11 AM

stings

#

strings*

proper glade May 7, 2020, 4:11 AM

#

that should be fine

barren elm May 7, 2020, 4:12 AM

#

Weird. I have a thread with a simple function and when I emit to the worker it does absolutely nothing. The thread and gui do start.

proper glade May 7, 2020, 4:12 AM

#

let's see the code

barren elm May 7, 2020, 4:13 AM

https://pastebin.com/HmfKYHji

Pastebin

Alert App - Pastebin.com

#

I can put it in hastebin instead if you wish

proper glade May 7, 2020, 4:14 AM

#

could you distill it down a bit

#

specifically to: the thread the worker is running in, the worker and maybe the part where the emission is occurring

#

or some line numbers so i know where to look for those

barren elm May 7, 2020, 4:15 AM

#

one sec

#

threading starts at 339

#

methods start at 444 for the GUI.

#

make that 425 for the methods. AddAlarm (line 444) adds some static info to my table and the runs MakeQuoteList( line 425)

#

MakeQuoteList is the method than emits the signal to the worker (line 13)

proper glade May 7, 2020, 4:25 AM

#

hmm

#

think that should be self.quotes.emit, no?

#

not sure how it works in pyside, but in pyqt i dont recall being able to emit from unbound signals

#

unbound as in not bound to an instance

#

is print(quotedict) being executed?

barren elm May 7, 2020, 4:28 AM

#

no it is not being executed.

#

think I got the signals mixed up?

proper glade May 7, 2020, 4:29 AM

#

not that i can see so far

#

just in the worker's slot, that quotes.emit at the end should be self.quotes.emit i believe

barren elm May 7, 2020, 4:30 AM

#

Yeah, I fixed that since making the pastebin. Still doesn't run for some reason.

proper glade May 7, 2020, 4:31 AM

#

are you sure MakeQuoteList is being called?

#

the threading and signal/slot setup seems ok to me

#

so the problem would seem to be elsewhere

barren elm May 7, 2020, 4:32 AM

#

I can double checkj. I had a print statement that worked earlier.

#

yes it does run.

proper glade May 7, 2020, 4:34 AM

is there a repo version i could run to test stuff out

#

looks like TD_Login is the only module missing

#

or i could try removing the bits using TD_Login

barren elm May 7, 2020, 4:35 AM

#

It is a stock alert app for ameritrade. The TD_Login module just grabs my OAUTH2 tokens

#

currently it should run without the module. Just have to comment out line 494.

proper glade May 7, 2020, 4:42 AM

#

well it seems to be working

#

the problem might be the request

#

i put a print('hello') at the top of GetQuotes and it runs

#

but i dont see print(quotedict) running

barren elm May 7, 2020, 4:44 AM

#

ooo, interesting.

proper glade May 7, 2020, 4:45 AM

#

oh i found the problem

#

i think

#

symlist.join(',') this is incorrect. it should be ','.join(symlist)

#

for some reason the exception isnt being printed out

barren elm May 7, 2020, 4:46 AM

#

ugh. You got it

#

Thanks!

#

I literally spent 2 days trying to figure this out and because the exception didn't print I had no idea i messed that up.

this is actually really bad

Oh i know. I am leanring this stuff so it is probably a giant mess

proper glade May 7, 2020, 4:49 AM

#

sys.excepthook = sys.__excepthook__ doesnt even fix it. looks like pyside (and maybe pyqt) silence all exceptions in slots

#

oh. Weird

proper glade May 7, 2020, 4:49 AM

oh an no worries

Thank you very much for the help!

proper glade May 7, 2020, 4:51 AM

#

it's all good. now im curious how to fix this

#

man they've really gotta avoid stuff like this

#

lots of knockback effects. e.g. i could imagine entire testing suites being broken by this issue

barren elm May 7, 2020, 4:53 AM

#

It might just be pyside. I believe they may have implemented signals and slots slightly differently

#

hence the code difference pyqtSignal() vs Signal()

proper glade May 7, 2020, 4:58 AM

#

huh interesting

#

it does seem to be just a pyside issue

#

i converted the imports to pyqt5 and exceptions print fine

#

and the program exits

#

does pyside have some extra exception handling machinery youre supposed to hook up maybe?

barren elm May 7, 2020, 5:02 AM

#

pyside docs are terrible on this particular subject of slots and signals.

Not sure about the exception issues. First time running into this problem

zealous abyss May 7, 2020, 5:02 AM

#

sorry to interrupt, but do you guys know anything about qthreads in pyqt?

#

my gui keeps freezing up even though my task appears to be in a different thread

barren elm May 7, 2020, 5:03 AM

#

Is this a joke or are you serious? I have to ask because that is what we just dealt with essentially 😆

#

post up a hastebin of your code

proper glade May 7, 2020, 5:04 AM

#

iirc there is an error signal for threads that you have to use in c++ qt

#

could be that?

#

yea go for it @zealous abyss

barren elm May 7, 2020, 5:05 AM

#

I bet it is.

zealous abyss May 7, 2020, 5:05 AM

#

k, lemme put that up

proper glade May 7, 2020, 5:07 AM

#

oh nah nothing about it in the docs, probably misremembering. or it couldve been someone's custom signal

#

wonder if a try/except would work to just emit the exception out

#

but then it would be very cumbersome doing that for each slot

#

so maybe a custom slot subclass

#

and it wouldnt propagate properly

barren elm May 7, 2020, 5:09 AM

#

I could probably form my code and run it on its own before using it with a thread.

zealous abyss May 7, 2020, 5:09 AM

#

https://hastebin.com/qoxanavube.py

#

thats not the full project, but just the stuff thats giving me an issue

#

when I run the program, it prints 1, then 2, then 3 and then freezes

#

but is qthreading not a seperate process?

proper glade May 7, 2020, 5:11 AM

#

    def __del__(self):
        self.wait()

this doesnt look kosher

zealous abyss May 7, 2020, 5:11 AM

#

i copied that from somewhere

#

is that not what it should be?

proper glade May 7, 2020, 5:12 AM

#

i would strongly suggest against doing it like that, rather keep the thread alive for as long as needed using a reference

zealous abyss May 7, 2020, 5:12 AM

#

why would I need to keep it alive?

#

or are you saying the program in general?

proper glade May 7, 2020, 5:13 AM

#

as for the freeze my guess would be webdriver might not be playing nice with qt's event loop. there could be some kind of multiprocessing conflict.

zealous abyss May 7, 2020, 5:13 AM

#

hmm

#

would there be a way around that?

proper glade May 7, 2020, 5:13 AM

#

i mean at the moment the lifetime of your QThread is within on_account_add

#

after which it will try to get garbage collected, and that's when __del__ will be called

zealous abyss May 7, 2020, 5:14 AM

#

oooooh

proper glade May 7, 2020, 5:14 AM

#

and blocked due to your wait call

#

so rather than doing it that way, keep the QThread object stored somewhere, e.g. in an instance variable

zealous abyss May 7, 2020, 5:15 AM

#

let me try that right now

proper glade May 7, 2020, 5:15 AM

#

that could actually be the freezing issue too, __del__ is probably called on the main thread

zealous abyss May 7, 2020, 5:16 AM

#

should I just get rid of __del__ and have it be its default?

proper glade May 7, 2020, 5:16 AM

#

yes

zealous abyss May 7, 2020, 5:16 AM

#

ok

#

now it just crashes

#

which is better id say

#

on that note, is there a way I can view errors that occur within the ui? right now almost everything that I pass off to it gives no feedback when it crashes

proper glade May 7, 2020, 5:18 AM

#

try adding sys.excepthook = sys.__excepthook__ before you run your program. sometimes certain terminals/ides dont play nice with how qt handles error output

#

actually now that i think about it some more, of course the issue would be the __del__. it's definitely being run in the main thread.

zealous abyss May 7, 2020, 5:20 AM

#

the excepthook line didn't work

#

it still closes as soon as I press the button this time

#

and it doesn't matter if I have the webdriver code running

proper glade May 7, 2020, 5:21 AM

#

try commenting out the webdrive rline

#

ah

#

whats the code for whatever happens when the button is clicked

zealous abyss May 7, 2020, 5:22 AM

#

its the on_account_add method

#

so all it should do is print 1, 2, 3, 4

#

but it stops at 2 then closes

proper glade May 7, 2020, 5:23 AM

#

is that it? just button.clicked.connect(on_account_add)?

zealous abyss May 7, 2020, 5:23 AM

#

yes

proper glade May 7, 2020, 5:23 AM

#

and you're keeping a reference to the thread now?

how're you doing that

Hi,
I have to call an API every 30 seconds and update the result in table in my PyQt5 TableWidget.

Now I know I cannot just wrap my API call in while loop because it will make my UI unresponsive.
I have tried running my while loop with QApplication.processEvents(), it solves my problem upto an extent but my UI is responsive only when program is asleep (time.sleep(30)).

Then I tried QRunnable. It is not advisable to update UI elements apart from main thread and while updating table it shows some <Vector(int)> error.

What should I do in this scenario? Is there a way to mix both (may sound absurd) QApplication.processEvents() and QRunnable?

dark basalt May 8, 2020, 8:54 AM

#

you should make use of signals+slots for this

#

the QRunnable (or QThread or whatever) emits a signal in its own thread. You make a connection to a slot in the main thread which updates the UI when the signal is emitted

#

there are some nice basic examples here: https://stackoverflow.com/questions/6783194/background-thread-with-qthread-in-pyqt

fossil gyro May 8, 2020, 9:00 AM

#

My thread will return a signal after completion (for ex. complete), and after my main thread receives this, it will update the table?

dark basalt May 8, 2020, 9:00 AM

#

yes

#

the two main things are 1) your QRunnable needs to run in its own separate thread so as to not block the main gui thread, and 2) your QRunnable needs a way to notify the GUI thread when it's done with its work

#

signals and slots work well for the second point

fossil gyro May 8, 2020, 9:11 AM

#

Thank you. I'll try to implement this.

fossil gyro May 8, 2020, 10:31 AM

Hi @dark basalt,
Where should I use while loop?
Before calling my Call API function or before calling the Worker class function?

Figured that out.

#

New question, how can I safely kill a thread by pressing stop button and restart it after pressing start button.

barren elm May 8, 2020, 7:52 PM

#

I have a button that deletes a row out of a QTableWidget (pyqt5/pyside2). the idea is to select the row you want to delete then hit the button.

#

Unfortunately if you keep hitting the button it will just delete other rows after the fact with no actual selections being made.

#

Hi fellow Humans.. I hope you can help me, cause the people on Stackoverflow give an answer like:"learn it"
I really dont understand what the problem is.. Everytime i used threads, i achieved that my code is going on while the thread does it own things, but in this case it doesnt. Maybe some of you can give me a more useful answer than 3 links that lead to nothing specific. I want to learn, thats not the problem.. but reading a big wikipedia article doesnt help me understand the problem.

So I made text editor, but I want to be able to click "run" button and then execute the text in say python for example

#

How do I go about this?

lucid wraith May 8, 2020, 10:51 PM

#

@cedar idol the "exec" builtin function can be used to execute a string as if it were python code. Create a function that grabs the text from the editor, makes sure it's safe to run, then uses the exec function on it.

cedar idol May 8, 2020, 10:53 PM

#

can you expand on the "make sure its safe to run" part? Like what in particular would I need to do

rocky dragon May 8, 2020, 10:54 PM

#

the make sure its safe to run part doesn't seem very relevant here

#

if it's a text editor then it should run anything

It's a bad idea to execute arbitrary code. Perhaps it's true that's an acceptable risk for a text editor.

Hey, does anyone know why a tray icon with PyQt5 is so long ? Like when you right click on a random icon and click somewhere on your screen, it close the menu instantly, but with PyQt5, when i right click, it take like 1 sec to open the contextual menu, and then if i click randomly on my screen, it take like 3 seconds instead of some ms to close the tray icon list
Don't know if i'm understandable, tell me if you need me to explain more

(copy paste from #491524019825278977 we told me to come here)

azure carbon May 9, 2020, 10:22 PM

Just to be clear, I have no error, it's just very slow like 3/4 sec. delay is abused for a very small code (just an icon, setToolTip, and a button)

@swift oak The closest you're going to get is something like async, threading, or multiprocessing.

#

But it depends on what you're doing, precisely, that requires simultaneous action.

Perhaps there's a sneaky way around your problem that doesn't involve using paralellism.

Hey all,
I have designed a main window and a form layout in QT designer. I am trying to open the form layout when a button in Main Window is clicked.
Here is my code

def scanswitch():
    mdi = QtWidgets.QMdiArea()
    Form = QtWidgets.QMdiSubWindow()
    mdi.addSubWindow(Form)
    formui = Ui_Form()
    formui.setupUi(Form)
    Form.show()


if __name__ == "__main__":

    app = QtWidgets.QApplication(sys.argv)
    MainWindow = QtWidgets.QMainWindow()
    ui = Ui_MainWindow()
    ui.setupUi(MainWindow)
    MainWindow.show()
    sys.exit(app.exec_())

I have added connection to the button in the main window class by doing
self.open_form.clicked.connect(scanswitch)

#

But when I execute the code, the main window opens as it should, when I click on the button, the sub-window popups and closes immediately how do I fix this?

@mossy bison honestly it could be a lot of things. If you are using PyCharm emulate the terminal in the console so as to see what is going on

📎 unknown.png

rocky dragon May 10, 2020, 5:54 PM

#

you need to link it to the method itself (self.menu1)

#

when you do self.menu1() you call the method and then tell the button to execute what that returns

simple marlin May 10, 2020, 6:04 PM

#

@rocky dragon Im new to this sorry. but what do you mean link it to the method itself?

rocky dragon May 10, 2020, 6:18 PM

#

In [1]: def connect(callable):
   ...:     print("What you're connecting to:", callable)
   ...:

In [2]: def func(): pass

In [3]: connect(func())
What you''re connecting to: None

In [4]: connect(func)
What you''re connecting to: <function func at 0x0000000004FB9708>

#

consider this

#

when you do self.menu() it's as if you replaced it by None because you execute the method and get what it returned

#

you want to connect to the actual method object, so you do that by not calling it

I don't know if this would fit into this category but I'm wondering how do you speed up a turtle in a canvas inside a tkinter window?
Normally, I would just do

import turtle
turtle.speed(0)
turtle.tracer(0,0)

However, when I am putting the turtle on a canvas inside a tkinter window, I'm not sure how do do this.

root = tk.Tk()
canvas = tk.Canvas(root,width=500,height=500) canvas.pack() t = turtle.RawTurtle(canvas) 
t.ht()

It seems strange that doing t.ht() works but t.speed() doesn't. Anyone have a solution?

Hello everyone. I'm stuck with Kivy.
How do I refer to the id of another class, which is not the root or main class?

I have a timepicker in .kv

<CircularTimePicker>:
id: timepicker
...
..

And I have a popup

<AlarmDialog>:
...
..
          Button:
            on_release: somefunction(app.ids.timepicker.time) #to take the time value of the time picker and put it into a list outside.

I have ran into similar issues in the past and I managed to eventually find workarounds, but I would rather keep these two classes separate in this case.

#

So how would I form that app.ids.timepicker.time part? App refers to the

class GUIapp(App):

    def build(self):
        Window.clearcolor = kivy.utils.get_color_from_hex("#bab86c")
        return representation

which has no timepicker

autumn badge May 11, 2020, 5:41 PM

#

@foggy pulsar you would use sticky

foggy pulsar May 11, 2020, 5:43 PM

#

thanks, i figured it out, its kinda janky but cool

autumn badge May 11, 2020, 5:44 PM

#

@loud sapphire i wont claim to be a kivy person (too many desktop limitations for my usage), but in alarmdialog, maybe set the on_release as a variable.
then in guiapp, def build(self, val)

#

@foggy pulsar yea, thats what i dont like about tkinter. i mean, it works and works well, but who knew you needed 100+ lines of code to make a box

#

i have been looking/playing around with "flexx". dont know if it will suit my needs or not, but figure i would try and recreate an app i already did with it

loud sapphire May 11, 2020, 5:47 PM

#

@autumn badge Hm, mind explaining that a bit further?

autumn badge May 11, 2020, 5:49 PM

#

you want this value:

            on_release: somefunction(app.ids.timepicker.time) #to take the time value of the time picker and put it into a list outside.```
to be present here right:
```class GUIapp(App):

    def build(self):
        Window.clearcolor = kivy.utils.get_color_from_hex("#bab86c")
        return representation```

#

oh.........kv files............yea, ignore me. i am an idiot with those

Why is my Qt application not closing when all my windows are closed? When I just have a main window, if I close it everything closes. But if I create a new widget during runtime and show it as a window, closing all the windows doesn't close the application anymore.

there's a qtoolbox widget

doesnt really look like that though

#

@dark basalt would you mind posting the code of this particular window? also when you create the other widget do you still have a mainwindow?

#

also you could try qApp.setQuitOnLastWindowClosed(True)

#

though this should be the default behaviour

@hollow pewter

hollow pewter May 12, 2020, 2:58 PM

It's a QDockWidget

proper glade May 12, 2020, 3:48 PM

oh i thought you were talking about 'dock' widgets in general, not qdockwidget. though qdockwidget doesnt do anything for the buttons and such.

#

there's also this: https://doc.qt.io/qt-5/qtoolbar.html with the option to make it automatically floatable and vertically oriented

do you have any sort of mutex to allow only a single instance of your app to be executed?

barren elm May 16, 2020, 1:32 AM

#

do you use an event loop in the thread?
@rocky dragon I am pretty sure it does start its own event loop in QThread automatically. Could be wrong. I do use a "While True:" in the thread but I have a way to end the loop. That is that stop_func_signal in my code

#

I don't have anything that would prevent more than one instance of my app.

rocky dragon May 16, 2020, 1:41 AM

#

There shouldn't be an event loop running if you don't call exec in the thread; just that quit does nothing without one

#

How are you running the app, just as a python script?

barren elm May 16, 2020, 1:42 AM

#

I converted it to an exe and that is where it gives me problems

rocky dragon May 16, 2020, 1:43 AM

#

What did you use for that? Pyinstaller?

barren elm May 16, 2020, 1:43 AM

#

Yup!

rocky dragon May 16, 2020, 1:43 AM

#

enable the console in there if you've got it turned off

mossy tusk May 16, 2020, 1:43 AM

#

damn, I don't really miss working on these annoying aspects of Python desktop apps.

barren elm May 16, 2020, 1:44 AM

#

Haha, trying to learn. I need to make another exe. I deleted the last one. I will keep the console on.

rocky dragon May 16, 2020, 1:44 AM

#

I'd recommend you use spec files if you're just invoking it with commandline args

barren elm May 16, 2020, 1:49 AM

#

I was having issues getting a new exe made. I did it with no arguments at all.

#

got it running

rocky dragon May 16, 2020, 1:50 AM

#

console remains up with the process?

barren elm May 16, 2020, 1:51 AM

#

No, it all closed out this time

#

Maybe it was doing that because I used --onefile the last time.

rocky dragon May 16, 2020, 1:53 AM

#

shouldn't affect it that much

barren elm May 16, 2020, 1:53 AM

#

Just realized, I had a crap ton of Python processes running.

rocky dragon May 16, 2020, 1:53 AM

#

but worth a try

barren elm May 16, 2020, 1:56 AM

#

ok, this time the command prompt did not close

#

err console did not close

rocky dragon May 16, 2020, 2:00 AM

#

well if we have the console then we can also use it for some debug prints

#

if qt didn't complain about anything then try putting a few of those around your program - and after the sys.exit

barren elm May 16, 2020, 2:05 AM

#

interesting. The console does not print anything.

#

Everything closes just fine prior to me using my login. I cheated and used selenium to log in to a stock sight.

#

I get this error after.

DevTools listening on ws://127.0.0.1:61260/devtools/browser/5cad39ac-11d0-4082-8fdf-79c59fc47d68

I want to install some plugins for Qt from github and I cant get it to work.
I am using Qt designer not creator.
I am using qmake command to get a makefile.
I installed mingw64.
I try to to use mingw command but I am getting a missing separator error
Am I even on the right track here? Is there supposed to be a much simpler way?

#

I need a dll but everyhting is pro files

barren elm May 16, 2020, 2:20 AM

#

Yup, the .wait causes the hang up. I commented out that line and it works just fine. I guess the thread wasn't closing out as a result.

EDIT: Nope. I was wrong. I think I may be using Qthread improperly... The program works but the thread doesn't allow the process to close completely.
EDIT2: It appears my While Loop in the thread was not terminating, that is now fixed.

Your code looks okay enough. Which leaves something to do with your system somehow. Like the kivy installation or some files in the wrong place or something configured incorrectly.

when running a PyQt5 script from PyCharm it runs fine, but when using the cmd I get the error "AttributeError: 'QComboBox' object has no attribute 'textActivated'"

Quick look at the docu says that QComboBox does have a "textActivated" signal

so what is the problem?

I reinstalled pyqt and the problem has been solved

probably pycharm was using a virtual environment with an updated version of pyqt when I had an older one on my regular python path

I'm trying to make a FakeRobot Display. My app will just show the location of the robot on an arbitrary x/y axis. I'd like it if the robot could animate to its position.

For animations, I found this: https://pypi.org/project/asciimatics/

I want to use Electron as a GUI tool with python, but when I look up videos. I never see them using Python but only HTML and JS. What role does Python have in a electron GUI?

#

Pls @ mention me when you reply

autumn badge May 21, 2020, 5:38 PM

#

@dense moat python has no role in electron. Electron is HTML/JS/CSS
If you want a HTML/CSS/Python gui similar, look at PyWebView

#

if you want pure python, you could look at flexx

dense moat May 21, 2020, 6:13 PM

Thanks!

spice dock May 22, 2020, 1:47 AM

#

You -can- use Electron as a GUI though. You can package up a python backend either as a stand-alone exe or you could bundle your scripts with it and rely on the host system to have python.

You can fire up your backend from js, then call rest endpoints in it for example on local host.

Here’s a simple example: https://www.techiediaries.com/python-electron-tutorial/

But I doubt many are doing it so it’ll be hard to find videos or tutorials like you mentioned @dense moat

In this tutorial, you'll learn to build GUIs for your Python applications using Electron and web technologies i.e HTML, CSS and JavaScript

This is my turtle program.
How can I implement the below idea?
When the y is kept pressing it must be it must keep the pendown else it must keep the pen up
How can I do that

turtle_1 = turtle.Turtle()

while True:
    if keyboard.is_pressed('up') == True:
        turtle_1.forward(6)
    if keyboard.is_pressed('down') == True:
        turtle_1.back(6)

    if keyboard.is_pressed('y') == True:
        turtle_1.pendown()
    else:
        turtle_1.penup()

Instead of waiting for a key to be pressed and then checking what key it is and acting on that, it'll constantly check if a key is pressed. This basically allows for multiple keys to be registered at once. Now the program will check if the Y key is being pressed. If it is, it'll put the pen down, otherwise it will penup().

turtle.done() shouldn't be used until the last line in the program as it starts the 'event loop' which basically means that it'll go into an infinite loop

#

So just remove that and it runs

@opal marsh This isn't really a theme. It's pull request, so a request for them to include said feature by modifying the code.
You can see it's been closed, so it was "denied". If you trawl through the comments, you can see this:
https://github.com/microsoft/vscode/pull/52707#issuecomment-507532140
Basically it requires upgrading their Electron version, which has a high chance of introducing new unknown bugs.

You'll basically need to build your own version of VS Code with this feature.

is kivy better than tkinter?

digital rose May 24, 2020, 4:52 PM

#

can someone help me integrate an image on tkinter with python?

#

Pls @ mention me when you reply

#

Speed please

sharp plover May 24, 2020, 7:32 PM

#

@digital rose Kivy is sexier than tkinter.

#

But I guess it's about what you need your application to do.

inner parrot May 24, 2020, 9:49 PM

#

PySimpleGui is the best

autumn badge May 25, 2020, 12:41 AM

#

Kivy is good if you don’t need mouse scroll ability. It is more of a click/drag method like phones.

#

PSG is good too

#

I really like flexx but compiling it is a pain. Haven’t gotten one to compile yet. Outside of that, it is probably my fav

#

Gonna try remi again though. I don’t think I have it a fair shake when I tried it the first time

autumn badge May 25, 2020, 3:29 AM

#

ok, for anyone trying out remi. if you are using pylint3 (or VSC for that matter), when you do your onclick.do command, you will get an error. you will get an error like Method 'onlick' has no 'do' member. just ignore this and give it a shot. 95% of the time, it is the linter, not your code

hey GUI people, I need a super simple GUI for a python program I am making, it literally just needs to open a window with some info and a couple of buttons. Any ideas

#

I can draw you a diagram of what I need if you want?

full elbow May 25, 2020, 7:27 AM

#

i made simple gui windows by picking up a tutorial on pyside2 (or pyqt5) ... fairly simple with the included designer and converters

formal wharf May 25, 2020, 7:27 AM

#

pyside2?

full elbow May 25, 2020, 7:28 AM

#

long story.. open source free software typical thing

#

i followed "tech with tim pyqt5" playlist on youtube

#

(then just use the pyqt5 online manual for reference)

formal wharf May 25, 2020, 7:31 AM

#

Excuse my MS paint diagram

📎 unknown.png

#

I need to make sure the pop up message appears over all programs that are running, it is paramount that I have it pop up over all other programs

full elbow May 25, 2020, 7:32 AM

#

yeah that looks simple enough for a basic pyqt5/pyside2 tutorial.. the included tools will do the heavy lifting, you'll just have to code whatever happens with the buttons/textboxes and showing/hiding windows ebtween actions

formal wharf May 25, 2020, 7:33 AM

#

ok, fair enough

#

just pip install it?

full elbow May 25, 2020, 7:36 AM

#

pretty much.. its one big package.. see if i get banned for posting a link here.. (not my channel) https://www.youtube.com/watch?v=Vde5SH8e1OQ&list=PLzMcBGfZo4-lB8MZfHPLTEHO9zJDDLpYj

I've never used tkinter before, but I want to create a simple program that keeps track of and calculates data, then displays it with tkinter's gui. I used the example on the documentation but im not sure how to update displayed text, can anyone show me how? I looked at a few things but it just looks overly complicated and confusing and I can't quite figure it out.

full elbow May 25, 2020, 7:43 AM

#

what control are you using to display the text?

#

(or widget)

cloud cove May 25, 2020, 7:46 AM

#

I was just using a label

full elbow May 25, 2020, 7:51 AM

#

something like this seems simple enough..
self.text = tk.StringVar()
self.text.set("This is my text")
self.label = tk.Label(self.root, textvariable=self.text)
then you use self.text.set("Updated my text") and tk will update it

#

(adapt to your code)

cloud cove May 25, 2020, 7:52 AM

#

thanks!

cloud cove May 25, 2020, 8:18 AM

so i got my code here and its looking good except the label text STILL doesn't update even though the variable does, can anyone help me find my mistake?

from tkinter import Tk, Label, Button, StringVar

n = 0

class Main():
    def __init__(self, master):
        global n

        self.master = master
        master.title("EMS")
        
        self.var = StringVar()
        self.var.set(n)

        self.l = Label(master, textvariable = self.var)
        self.l.pack()

        self.b = Button(master, text = "add", command = self.add)
        self.b.pack()

    def add(self):
        global n
        
        n += 1
        print(n)
        print("success!")

root = Tk()
my_gui = Main(root)
root.mainloop()

full elbow May 25, 2020, 8:20 AM

#

@cloud cove you have to use self.var.set() to update the variable assigned to the label

digital rose May 25, 2020, 8:20 AM

#

Thanks ems

cloud cove May 25, 2020, 8:21 AM

#

on my 13th line i have self.var.set(n)

full elbow May 25, 2020, 8:21 AM

#

yes, but you want your label to update after your add() call right?

cloud cove May 25, 2020, 8:21 AM

#

yeah

#

so do i add that to add() too?

full elbow May 25, 2020, 8:22 AM

#

yep

cloud cove May 25, 2020, 8:22 AM

#

and should I remove it from _init_ or no

full elbow May 25, 2020, 8:22 AM

#

no

cloud cove May 25, 2020, 8:22 AM

#

ok, thanks

#

ill try that

#

ahhh yes it works

#

its so simple but i feel so proud lol

#

it counts

full elbow May 25, 2020, 8:25 AM

#

gui programming isn't easy, another notch on your belt 😉

cloud cove May 25, 2020, 8:25 AM

#

yeah haha

#

i've always just stayed away from tk and stuck with command line because it was too intimidating

#

its a big leap but im feeling good about what I have so far

digital pollen May 25, 2020, 8:25 AM

#

Yeah I'm trying to do a simple GUI with Tkinter and godamn it feels like it's harder than it should be

cloud cove May 25, 2020, 8:26 AM

#

yeah lmao

#

my question is does the code run every frame? and is it 60fps?

digital pollen May 25, 2020, 8:26 AM

#

I'm so used to VS and just dragging stuff from the toolbox

full elbow May 25, 2020, 8:30 AM

#

code runs when code runs.. shouldn't be affected by the fps..

cloud cove May 25, 2020, 8:30 AM

#

alright, i have no idea how this works

#

my knowledge is from game development where (from most of what ive seen) code runs 60 times a second

digital pollen May 25, 2020, 8:31 AM

#

If it's on the update method (Usually, not always the case)

cloud cove May 25, 2020, 8:31 AM

#

so how does it work with stuff like this then?

digital pollen May 25, 2020, 8:32 AM

#

I think mainloop() does something similar

#

But again, I only just learned tkinter lmao

full elbow May 25, 2020, 8:33 AM

#

yeah mainloop() makes your program enter an event loop managed by TkInter

cloud cove May 25, 2020, 8:34 AM

#

alright

#

so another thing

#

if im having it pull data to put as a text label, it is more efficient to just have it pull from a text file every time it runs or to store it to a variable that only pulls from a text file a few times

#

reworded it because i realized my original wording made very little sense

full elbow May 25, 2020, 8:38 AM

#

if your text file isn't changed during runtime.. def limit your file read to a single one at initialization

cloud cove May 25, 2020, 8:39 AM

#

ok, thanks

cloud cove May 25, 2020, 10:03 AM

#

so im trying to make my program create a text file with its name based on the StringVar "name", but when i try to print that StringVar or concatenate it as a string it just shows up as "PY_VAR0". is there any way to get the actual value of this variable?

#

got my answer, i needed to use self.name.get() rather than just using self.name

cloud cove May 25, 2020, 10:41 AM

#

How do I check which item is selected in an optionmenu?

#

nvm, got it

small cairn May 25, 2020, 6:11 PM

#

@cloud cove you mean you want to get an input from a user ?

cloud cove May 25, 2020, 7:06 PM

#

yeah thats what I mean with the former messages I sent, and that's also somewhat what I meant with the latter messages

#

but i got it all figured out

cloud cove May 25, 2020, 8:01 PM

#

so i have an optionmenu with a few options and I have it set so every time its changed it will run the crawl() function but it doesn't initially and I want to know how to get it to run just once at the very start after the default is selected. here's my code:

        self.var = StringVar(master)
        self.var.set(profiles[0])
        o = OptionMenu(master, self.var, *profiles)
        o.pack()
        self.var.trace("w", self.crawl)

all of that is contained within _init_ in my Main() class

lusty slate May 25, 2020, 8:22 PM

but i have this error

from what i understand i have to put a path in the argument

#

how i can export the path of the image after i input in the application

cloud cove May 25, 2020, 8:34 PM

#

got my answer, needed to put var.trace between the initialization and assignment of the variable

cloud cove May 26, 2020, 12:06 AM

#

I'm trying to place a background image into my program using this code that many other said worked. its not throwing errors but its not showing any images and I'm not quite sure why. here's the relevant code:

class Main():
    def __init__(self, master):
        global profiles
        
        self.master = master
        master.title("Anime Tracker")

        topFrame = Frame(master)
        topFrame.grid()
        bottomFrame = Frame(master)
        bottomFrame.grid()

        background_image=PhotoImage("miku.jpg")
        background_label = Label(master, image=background_image)
        background_label.place(x=0,y=0,relwidth=1,relheight=1)

root = Tk()
my_gui = Main(root)
root.mainloop()

blissful narwhal May 26, 2020, 12:29 AM

#

Can I make the buttons in my gui affect variables in my python code?

cloud cove May 26, 2020, 12:30 AM

#

you can link them to functions, so yes

blissful narwhal May 26, 2020, 12:31 AM

#

any good tutorial or documentation for that?

cloud cove May 26, 2020, 12:31 AM

#

b = Button(root, text = "My Button Text", command = MyFunction)

#

obviously you will have to change that to adapt to your code

#

but you use the command= argument

blissful narwhal May 26, 2020, 12:35 AM

#

I see

any suggestions?

rocky dragon May 27, 2020, 2:25 PM

there's eel for electron

#

But there should be no problems with the licenses with PySide2 (or pyqt too if you're not doing proprietary apps)

#

or run a local flask/bottle/django or other backend framework server that you connect to with the browser

sick forge May 27, 2020, 2:26 PM

Awesome

I also had the flask idea

might go with that

sand violet May 27, 2020, 9:24 PM

#

@sour prism sorry, what I meant wasn't tabs

#

i meant basically a way to change layouts

#

pysimplegui is close but still

sour prism May 27, 2020, 9:24 PM

#

Change layouts?

sand violet May 27, 2020, 9:25 PM

#

change the current list of widgets to a completely new set

#

pyqt5 is interesting but I think making my own will be better

sour prism May 27, 2020, 9:26 PM

#

Yes, PyQt5 allows you to do that - each tab has it's own layout.

sand violet May 27, 2020, 9:26 PM

#

I don't want tabs at all

#

I want layouts that I can switch between at the click of a button

sour prism May 27, 2020, 9:26 PM

#

You can also dynamically change the layout.

sand violet May 27, 2020, 9:26 PM

maybe

sour prism May 27, 2020, 9:26 PM

Hmm.

sand violet May 27, 2020, 9:27 PM

but question, do you think this is readable

#

        ], 
        text_color = 'red'
    )
]

sour prism May 27, 2020, 9:30 PM

#

Far more readable that PyQT5 or other GUI libraries.

#

A bit unusal in the top-down structure

#

For example - what if you wanted an object horizontal to another?

sand violet May 27, 2020, 9:30 PM

#

If you wanted two objects next to each other use columns

sour prism May 27, 2020, 9:30 PM

#

BTW I'm not familiar with PySimpleGui.

sand violet May 27, 2020, 9:30 PM

#

Don't get familiar with it, it's a mess

#

@sour prism You'd use columns for two objects next to each other

#

[
  [
    'First Object', 'Second Object to the right of the First'
  ]
]```

#

That's two objects next to each other

#

[
  'First Object',
  'Second Object below the First'
]

#

That's one object below another

sour prism May 27, 2020, 9:32 PM

#

Ah right.

#

Yeah, I think it's quite intuitive.

sand violet May 27, 2020, 9:33 PM

#

What about this

#

@gui.on('button press')
def button_press(button):
  print(f'You pressed the button {button}')

#

@sour prism is that intuitive?

sour prism May 27, 2020, 9:36 PM

#

Yup. How do you specify the correct button to connect it to?

#

Oh right.

#

The button is passed in, instead.

#

That's simpler than connecting individually, but then you have to have large if-statements for routing the correct result (if you see what I mean).

sand violet May 27, 2020, 9:38 PM

#

@sour prism Well, it's easier then tkinter

sour prism May 27, 2020, 9:39 PM

#

That's not saying much.

#

I've avoided Tkinter like...

sand violet May 27, 2020, 9:39 PM

#

it's a lot easier then tkinter and much more readable

sour prism May 27, 2020, 9:39 PM

#

I dunno but I hate it.

#

Don't even know why it's recommended for beginners to use.

sand violet May 27, 2020, 9:40 PM

#

@gui.on('button press')
def button_press(button):
  if button.id == 'button1': 
    print('button1')
  elif button.has_class('cool_button'): 
    print('its a cool button")

VS

button1 = tk.Button(root, label = 'text')
def callback():
  print('button1')
button1.bind(callback)
def cool_button_call():
  print('its a cool button')
for button in cool_button_list:
  button.bind(cool_button_call)

@sour prism which do you prefer?

#

Honestly the latter simply due to the extra complexity of having to route the events.

Why would you like complexity?

#

The goal is simplicity, for it to be easy

#

@sour prism Why would you want complexity?

#

Doesn't complexity make it less readable and harder to use?

#

No I think the former may end up becoming more complex

#

Once you add in a few more buttons.

#

I think something nicer would be:

Button(..., on_press=func)

Actually, mine is less complex and won't become more complex

#

And @sour prism , decorators are better syntax

#

Also, note that my syntax means that it is extremely easy to group buttons together

#

You can check if they have a specific class, have a specific ID, you can easily classify them, all without a hassle

Oh yeah. How about this:

@gui.on('button1 pressed')
def ...

#

I wonder if there's a way to make that less "stringy"

#

Like gui.onbuttonpressed

#

Or something...
