Guys ,I want to structure my pyside2 project. This is the folder structure that I am thinking to go with. I am creating a gui using qtdesigner and then exporting it to python program so I wont be using .qml files for gui . There is utils folder for all utility funtions and also a resources folder where I will be placing all the icons and images to display on the gui. I will run my project using the main.py file. There will also be files that will be exported using the application. while the project will run normally using the terminal but if I am going to package my project using pyinstaller I am not sure it is going to function properly. If anyone of you have used pyinstaller before can suggest me how my folder structure should be and how I can package my project using pyinstaller using same folder structure
project /
utils /
init.py
file1.py
file2.py
views/

Am I using this correctly?
user = user_name_ent.get()
password = user_pass_ent.get()
ok_button = tk.Button(master=confirm_buttons_frm, text="OK",
command=lambda: create_user(user, password))
The create user function works independently just fine, but the parameters are not passed to the SQL DB.
safe cipher
Lambda has arguments too
lambda user, password: create_user(user, password) for example
lofty wyvern
That was just me trying something out. Even without the lambda the data is not passed
This is it now
ok_button = tk.Button(master=confirm_buttons_frm, text="OK",
command=create_user(user, password))
Might be something else in my code, I'm only a week in and no formal training
safe cipher
yeah, you have to get user and password from somewhere
Where do you define the 2 vars?
and also, this wont work as you have to pass a callback and dont call it
lofty wyvern
About 10 lines up
user_info_frm = tk.Frame(master=new_user_window)
user_name_ent = tk.Entry(master=user_info_frm, width=25)
user_name_lbl = tk.Label(master=user_info_frm, text="New user name")
user = user_name_ent.get()
user_pass_ent = tk.Entry(master=user_info_frm, width=25)
user_pass_lbl = tk.Label(master=user_info_frm, text="New user password")
password = user_pass_ent.get()
and whats the issue? the params do get passed, but it instantly gets executed
lambda should work tho
(the first implementation)
lofty wyvern
I have a function built that takes that info and puts it into an SQL data base. The other info that is defined inside the function is added but nothing but blanks in the user and pass fields
lofty wyvern
No, not anywhere in the code
static cove
So this issue is that the .get() functions aren't grabbing what's inputted into that entry box or that the information isn't get appropriately saved to the db?
lofty wyvern
correct
static cove
!paste could you paste your full code here?
proven basinBOT
lofty wyvern
I might have messed some stuff up trying to fix it
I can link the working code I had yesterday that the function is based on, it's saved on git hub.
static cove
In your create_user() function, you re-define user and password to "", overwriting whatever is passed in
lofty wyvern
Yeah, that was something I added trying to fix. I removed them and its the same issue
static cove
well, you definitely want to use the lambda in that command= call you had earlier
lofty wyvern
gotcha, let me try readding that without the arguments in the function
static cove
OH. I know what the issue is
lofty wyvern
π
static cove
You want your command code to be:
ok_button = tk.Button(master=confirm_buttons_frm, text="OK",
command=lambda: create_user(user_name_ent.get(), user_pass_ent.get()))
the GUI only launches once your code reaches root.mainloop(), anything before that is run before the user can even interact with it
So your code where you grab the user and password is done before the user has entered anything, hence why it's returning the blank strings
The code above will only pull the values from the entry boxes when the user presses the button
lofty wyvern
Awesome, I'll check that as soon as I get back. Thank you! I'm still very new to this. You rock
static cove
No worries~ happy to help

Hey! I'm trying to make a GUI in PyQt5 for editing a JSON list of hundreds of thousands of words. Since the list is so long, it's literally impossible to display it all in one label without it crashing, which is to be expected. So, I thought a good workaround would be to use tabs that dynamically load a long enough list of words where it is just short enough to not crash (however, at the moment I am just displaying 64 words per tab). I was originally going to use QTabWidget but I realized that it needed to have all the tabs in memory for it to work, which is even worse than just the list. However, I found that I can create just a QTabBar by itself to avoid this. But, for some reason, my QTabBar isn't emitting the currentChange() signal when I switch tabs. Any ideas what I am doing wrong? Or is there any better ways to do this? Sorry if my code is messy, I'm very new to Qt so only got the hang of it a few hours ago lol
Here's my full code at the moment: https://hastebin.com/orepuzodey.rb

@buoyant tendon Are you actually using a QLabel or something like QTextEdit/ QTextBrowser?
buoyant tendon
I don't know what QTextEdit or QTextBrowser are so a QLabel π
static cove
So I highly recommend using a QTextEdit. It'll be better suited for displaying a list of text items.
buoyant tendon
I feel like there will be no possible way to display 600,000 words at once without significant lag, though
static cove
mmmm, let me test something real fast
orchid yoke
Is it better to store settings for an app in json?
buoyant tendon
Could you please explain how QTextEdit would do this? As far as I can tell, it just makes you able to have both rich text and standard text in one object, which is anything sounds like it would be worse for performance
stoic vale
Is it better to store settings for an app in json?
Some app like Visual Studio Code do it.
buoyant tendon
It's also worth noting I plan on making each of these words selectable so you can run functions on many words at once (deleting them from the list, duplicating them, making a filter with them...)
stoic vale
What's about QPlainTextEdit? https://doc.qt.io/qt-5/qtwidgets-mainwindows-application-example.html
buoyant tendon
Let me have a look
stoic vale
QTextEdit also OK. https://doc.qt.io/qt-5/qtwidgets-richtext-syntaxhighlighter-example.html
buoyant tendon
That's a lot of code and information @_@ I don't quite know what I'm supposed to be looking at
static cove
I mean, QTextEdit works for me. It takes a bit to do ctrl+c and ctrl+v and it takes a bit to spin it up, but I don't know how you'd get past that with over half a million words.
stoic vale
I just give you some examples of building a text editor in QT.
buoyant tendon
Well, surely the option would just to be to display only a small amount of words at any one time, which is what I was originally trying to do?
static cove
Well you said it was literally impossible to display it without crashing, which is not the case with QTextEdit.
But for the signal not emitting, can you post your code for how you're using the signal?
buoyant tendon
static cove
I don't see where you actually connect to the signal though. Are you familiar with how Qt's signal/slots work?
buoyant tendon
As far as I knew, I was just overriding a function on the parent class and when an event occurs, that function is called? It worked for resizeEvent so I thought it would be the same for the currentChange one
static cove
That's not really how Qt's signals/slots are intended to work
There is a currentChanged() signal for QTabBar
Uhm... let me write up a quick example for how it's typically supposed to be used
I think that'll be the clearest way
buoyant tendon
Alright, thank you π
static cove
give meeeeee 3 minutes
@buoyant tendon Check out this code for how to connect your own function to a pyqt signal. It's super basic but hopefully it's clear.
from PyQt5.QtWidgets import *
from PyQt5.QtCore import *
from PyQt5.QtGui import *
import sys
class MainWindow(QMainWindow):
def __init__(self, *args, **kwargs):
super(MainWindow, self).__init__(*args, **kwargs)
self.mywidget = QTabBar()
layout = QVBoxLayout()
# Setting up a super basic QTabBar with 2 tabs
layout.addWidget(self.mywidget)
self.mywidget.insertTab(0, "Tab 1")
self.mywidget.insertTab(1, "Tab 2")
# Let's connect to the signal 'currentChanged' and attach it to our own function 'tab_changed'
self.mywidget.currentChanged.connect(self.tab_changed)
# Adding it to the layout
widget = QWidget()
widget.setLayout(layout)
self.setCentralWidget(widget)
def tab_changed(self, *args):
print("tab changed!")
print(args)
app = QApplication(sys.argv)
window = MainWindow()
window.show()
app.exec_()
mmmm probably should've paste bin'd that but oh well
buoyant tendon
Ah, so I don't even need a need class for it π
Thank you so much, let me try it π
static cove
It's still useful to subclass if your tabs will have unique functionality, but yeah. That's how you connect your own functions to the signals emitted by the default classes.
If you make your own subclasses you can also add your own signals which is useful
You'd typically only need to override the existing signals if you want to fundamentally change behavior that pyqt does.
It's not common that you'd need to do that
buoyant tendon
Makes sense
static cove
I really like the design behind pyqt's signals and slots~
buoyant tendon
It works π Thanks so much π
plush stream
How do i close all my secondary window when i close my main window? I have three window classes; QMainWindow and two QWidget
bronze basin
@plush stream
you can connect the close function i am pretty sure to another function as well as the self.close() functtion
so inside that function you can make an instance of your other classes or windows
and close them all there as well
plush stream
Okay thanks, but how do i connect the close button in the title bar? I know how to do it in tkinter but not in pyqt
bronze basin
wdym @plush stream
are you using the standard windows title bar
the method i said for will work well with a custom title bar and custom close button
plush stream
Yes i did
bronze basin
i am not sure how to do it for the standard title bar
maybe look it up
but should be the same way i said except the button or connecting will be different
i suppose

Okay, thanks π

in tkinter, is it better to to:
a = Label(root, text="hi")
a.pack()
or:
a = Label(root, text="hi").pack()
?
inner nest
first method is more readable i think especially if you add some parameters on pack() method
brittle hull
I'm stuck trying to plot realtime data, could someone give me a hand?
static cove
What framework are you using?
brittle hull
Umm, I'm working on Pycharm. I have tried to plot with pyplot and with pyqtgraph (that you mention a few days ago). Sorry if I don't answer properly, I'm a newbie π
This is a part of the script:
import pyRofex
import pandas as pd
AL30_T2 = "AL30 - 48hs"
AL30D_T2 = "AL30D - 48hs"
tickers = [(AL30_T2, None, None, None, None, None),
(AL30D_T2, None, None, None, None, None)]
Create empty DataFrame to store Data
prices = pd.DataFrame(tickers, columns=["Ticker", "Time", "Price"])
Initialize the API connection
pyRofex.initialize(config.user, config.password, config.account, pyRofex.Environment.REMARKET)
def market_data_handler(message):
prices.loc[prices['Ticker'] == message["instrumentId"]["symbol"], 'Time'] = message["marketData"]["LA"].get("time", None)
prices.loc[prices['Ticker'] == message["instrumentId"]["symbol"], 'Price'] = message["marketData"]["LA"].get("price", None)
pyRofex.init_websocket_connection(market_data_handler=market_data_handler)
pyRofex.market_data_subscription(
tickers=[AL30_T2,
AL30D_T2],
entries=[pyRofex.MarketDataEntry.LAST],
depth=1)
It's a websocket connection that received market data from two items. I need to graph the timestamp in the x-axis, and the price in the y-axis, like a time series; I've tried to update the plot but I couldn't. Sorry if my message it's too long or not proper
static cove
So which plot are you using for the script?
brittle hull
i trying with pyqtgraph, beating my head against a stone wall
static cove
So, overall your code should probably be structured something like:
function that receives/pulls data --calls--> function that processes data --calls--> update your pyqtgraph data + call .processEvents() to get the graph to update
brittle hull
Done! great help, greatly clarifying
pw = pg.plot()
while True:
pw.plot(date, price, clear=True)
pg.QtGui.QApplication.processEvents()
And works! just need to beautify the x-axis π

neon ibex
in tkinter how do i insert to an entry what is said on a button
so lets say i have the number 5 on the button and a number 1 on a button, when i press one or the other (there are a total of 9 buttons) i want to print what is said on the button
i could show you what i mean through a code
neon ibex
so anyway here is the code
self.exit_button = Button(master, text = "Exit", pady = 20, padx = 20, command = master.quit)
self.exit_button.grid(row = 2, column = 0)
self.clear_button = Button(master, text = "CE", padx = 20, pady = 20, command = self.clear_entry)
self.clear_button.grid(row = 2, column = 1)

it prints 1

that would be many lines of code
if it was shorter i would do it that way but now in this case it would be too long.

yes there r 9 numbers
i would need to write 9 different methods (because it is in a class)

if i would have 2, your way would work very well
but now i need a shorter way because i dont want to write extra lines of code

this could be a solution if you fit self.insert_number accordingly
self.btns = []

using the _handler like that for default arguments is super icky but unfortunately the only way

if you punch it in the right ways, you can make tkinter look really decent
although it will involve ttk's create_image command and that always slows down redrawing upon window resize really heavily

Hi Guys I have a OOP question . its regarding the super() method.
I know the following usage of super()
def _init_(self, var_1, var_2, var_3 ):
super()._init_(var_1, var_2)
self.var_3 = var_3```
so in this case the super method says to get var 1 and 2 from the ParentClass and the var 3 from the this _init_ method right ? I just saw some code where it was like below.
```class MainWindow(QtWidgets.QMainWindow):
def _init_(self):
super(MainWindow, self)._init_()```
this time the variables are inside super(....) and not super()._init_(.....) like before. I am confused at what this is doing ? any help is appreciated
tawdry idol
@teal hearth they're two different things
notice that in the first case stuff is passed to __init__
and in the second case stuff is passed to super()
and in the second case stuff is passed to
super()
@tawdry idol this is, loosely speaking, to helpsuper()find out which superclass you want the__init__from
in the first case you could well do super(MyClass, self).__init__(var_1, var_2) (incidentally, note that it's two underscores, so your code is wrong)
for the same effect.
and I believe that was necessary in Python 2, but no longer
look up help(super), that might help.
teal hearth
@tawdry idol thank you . yeah I mispelled the double underscore. sorry. so If super(MainWindow, self).__init__() means which super class I want __init__ from . why am I supposed to define it in the MainWindow class it self. I am already inside the MainWindow class and in the init function as well. why do I need to explicitly say that there ? to prevent it from accessing the Qt.Widgets.QMainwindow class's init function ?
tribal path
Yea its unneeded in py3. Its py2 syntax, but will work in py3 as well. If you dont need to add code to the subclassed init, you dont need to define one at all

@plush stream you need to create a custom frameless widget and it needs a widget to mock the functionality of a title bar. Then use the custom window to wrap your widget
if you do that you can apply the transparency to all but the title bar or just certain portions of the UI

I have a problem with a stubborn QWidget inside a scrollArea. It doesn't want to take up it's minimum amount of space. I've tried setting size policy to minimum, set minimum height to 0, but nothing seems to work. Any ideas? (I'm working in PySide2)
eager beacon
have you tried scrollArea.setWidgetResizable(True)?
ruby pawn
Yes
This is with scrollArea.setWidgetResizable(True) and green is the widget's background color
And here it is with scrollArea.setWidgetResizable(False) and red is the scrollArea's background
So that leads me to think it is the scroll area that makes the widget scale up to fit the scrollarea
eager beacon
So what behavior are you looking for?
ruby pawn
I basically want it to be the exact length of it's content
It shouldn't be taller than the two bars named "Name Editor" and "Settings" combined.
If I unfold one of the bars, it does get the exact length. It's just that it can't go small enough.
Here is with one of the bars unfolded. And it doesn't force the scroll area to be a tiny bit too long
eager beacon
So the scrollArea should always be the same height it is in the red/green screenshots?
ruby pawn
No the scroll area should never force the window taller. The scroll area should be as long as the window height allows it. But when I scale the window down to it's minimum height, there shouldn't be any extra green/red at the bottom.
Basically the problem is that the scroll area won't scale down enough vertically. It forces an extra about 28 px even though the minimum height is set to 0
eager beacon
try setting it to 1
ruby pawn
Alright 2 sec
eager beacon
wait
ruby pawn
?
eager beacon
whats the sizePolicy?
ruby pawn
Minimum, minimum
eager beacon
vertical
ruby pawn
On literally everything
eager beacon
try setting vertical to Preferred
ruby pawn
If I set the minimumHeight to 100, it scales up to 100px, but it won't go lower than 48 pixels
Okay
Setting it to preferred allows me to scale it down to 0, but it doesn't initialize in minimum size
eager beacon
what is the minimum height on the Widget that you used for scrollArea.setWidget(Widget)?
ruby pawn
it's also 0
And set to minimum, minimum
this is with preferred, if I scale it down as much as possible
But this is what it looks like when initialized
And I want it to look like this when I open it, and I don't want it to be able to be scaled shorter than this. But it needs to be able to scale taller.
lofty wyvern
Could someone help me out with this? I have been trying to pull the information from the entry fields and place them into a list for later use. Best I have been able to do is just pull the last field.

Can you post the code for the expanding group boxes and scrollArea?
ruby pawn
I can't post the code for the expanding group boxes because I call their creation in Autodesk Maya. It is not something I have written myself.
I basically create them using Maya's own scripting language and then grab the Qt object after creation and work with that
But here is for the scroll area, and I apologize for it being messy I've just been throwing stuff at the wall to see what sticks ```python
self.scrollAreaLayout = QVBoxLayout()
self.dropdownLayout = QVBoxLayout()
self.dropdownLayout.setSpacing(0)
self.dropdownLayout.setMargin(0)
self.nameEditorContainer = QVBoxLayout()
self.extraSettingsContainer = QVBoxLayout()
self.dropdownLayout.addLayout(self.nameEditorContainer)
self.dropdownLayout.addLayout(self.extraSettingsContainer)
self.nameEditorContainer.addWidget(self.editorWidget)
self.extraSettingsContainer.addWidget(self.extraSettingsWidget)
self.dropdownLayout.setStretchFactor(self.nameEditorContainer, 0)
self.dropdownLayout.setStretchFactor(self.extraSettingsContainer, 1)
self.scroll = QScrollArea()
self.scroll.setMinimumHeight(1)
self.widget = QWidget()
self.widget.setStyleSheet('QWidget {background-color: green;} QVBoxLayout {background-color: blue;}')
self.widget.setMinimumHeight(1)
self.scroll.setSizePolicy(
QSizePolicy.Minimum,
QSizePolicy.Preferred
)
self.widget.setSizePolicy(
QSizePolicy.Minimum,
QSizePolicy.Minimum
)
self.widget.setLayout(self.dropdownLayout)
self.scroll.setHorizontalScrollBarPolicy(Qt.ScrollBarAlwaysOff)
self.scroll.setWidgetResizable(True)
self.scroll.setWidget(self.widget)
print(self.scroll.sizeHint())
self.mainLayout.addLayout(self.scrollAreaLayout)
self.scrollAreaLayout.addWidget(self.scroll)
self.mainLayout.setStretchFactor(self.nameLayout, 0)
self.mainLayout.setStretchFactor(self.settingsLayout, 0)
self.mainLayout.setStretchFactor(self.scrollAreaLayout, 0)```
Okay the indentation messed up a bit
@eager beacon Okay this is odd. I set the minimum size to 44, which is apparently the height I want it at. And then I added a self.adjustSize() right after self.setLayout(self.mainLayout) and it fixes the issue. If I set the self.adjustSize() before the setLayout or after I add he scrollArea it doesn't work.
eager beacon
oh
well in that case couldn't you use scrollArea.setSizeAdjustPolicy(QAbstractScrollArea.AdjustToContentsOnFirstShow)
the base policy ignores size adjustments
ruby pawn
I'll try
I have a new problem though
Window doesn't get automaticly longer when I unfold one of the bars anymore. It used to force the scroll area and window taller
Maybe that is the size policy?
eager beacon
Minimum will do that
ruby pawn
The setSizeAdjustPolicy didn't work
eager beacon
might try AdjustToContents then
it will adjust anytime the scrollArea viewport changes
ruby pawn
Just tried, didn't work
It doesn't change at all
Unless I manually resize the window
Not sure how I fucked it up
eager beacon
Do you know the size of your group boxes when expanded ahead of time?
ruby pawn
I will when they are done
eager beacon
you could just change the sizeHint then
ruby pawn
I'd have to do that dynamically when I open and close them?
eager beacon
yeah. you could emit the size, or something else, depending on how you wanted to do it
ruby pawn
How do I set a size hint?
eager beacon
scroll.sizeHint = lambda s=QtCore.QSize(400,200):s should work since you aren't subclassing the scrollArea
or you could define a normal function and assign that as the sizehint
doesn't really matter, it just needs to be a function that returns a QSize
ruby pawn
It works
eager beacon
what does
ruby pawn
The command to change sizeHint
But how will changing the size hint make the scroll area get the right size?
If I adjustSize() it jumps back to that weird spot it has always wanted to be in
eager beacon
you can try updateGeometry instead
but why do you even need adjustSize if the sizeHint is working?
ruby pawn
Oh I mean it's literally changing the number
Not that the window is actually following those sizes
eager beacon
hm, if you change a sizeHint and then explicitly call updateGeometry the size of the widget should be updated
ruby pawn
It updates horizontal, but not vertical
eager beacon
check the sizePolicy for vertical
ruby pawn
I changed it back to minimum
Should it be preferred?
Welp, doesn't make a difference
eager beacon
can't you remove the policies if you're setting the sizeHint?
ruby pawn
Sure let me give it a shot
No difference
I've tried setting it to scale to 1000 px vertically on updateGeometry and it's like "Nah boi"
eager beacon
is the widget containing the scroll area enforcing a maxHeight or something else?
ruby pawn
Only minimum height
eager beacon
maybe a Maximum SizePolicy
ruby pawn
This is all the things I call on self.scroll
What the fudge is it about QScrollArea that wants to be 74 pixels tall
eager beacon
pretty sure thats the combined sizeHints of your boxes within
ruby pawn
Let's figure it out
eager beacon
+- any contentsMargins on layouts or widgets
how tall is a collapsed widget?
the group box thing you have
ruby pawn
They're 44 together, so 22 individually
sizeHint for the boxes are 75 wide and 22 tall per group box
eager beacon
have you removed all of the contentsMargins on widgets and layouts?
eager beacon
setContentsMargins
ruby pawn
Ah, let me try
eager beacon
scrollLayout too
ruby pawn
Aight, gimmie a sec
eager beacon
You can also apply it to the widgets, but I'd think that would be taken care of by the qss
ruby pawn
Okay I think I have found a mistake
I think I've made some kind of mess up between self.scrollAreaLayou and self.dropdownLayout. I need a minute or two to figure out wtf I've done
ruby pawn
Thanks for all the help Chris
stray jackal
speaking of GUIs - is there any logic behind Star Treks LCARS displays???
ruby pawn
@eager beacon sadly I'm gonna have to go catch some Z's, but I've hooked up functions on expand and collapse for both of the bars and then I hope to get current size of the window and add or subtract the height of that group box. And we'll see how that works. Thanks for all your help, it is much appreciated. π

in makeform, or create_list?

The makeform is working, but that's where the entries are. I'm using the create list to build a dynamic list

amber roost
How are you going to get text from entries that you have no reference to?
lofty wyvern
Might be my issue, I've tried a lot of things and probably deleted them.
I'm only two weeks into learning python so it could be something as simple as that
amber roost
for x in self.data_needed:
self.text = self.ent.get()
self.input_data.append(self.text.get())
You only have x as a loop variable and do not use it
eager beacon
def create_list(self, event):
for x in self.input_data:
self.text = x.get()
print(self.text)
that seems to work
amber roost
You only have self.ent to query and it is not going to change
lofty wyvern
Awesome, thanks y'all! I'll give that a go.
amber roost
input_data will only contain the text the entries were created with
so a bunch of empty strings
you will need to store the references to the entries themselves in a list and call .get on them for create_list
something like
def makeform(self, ...):
self.form_entries = []
for i in self.data_needed: #why is it both a self attribute and a parameter?
...
ent = tk.Entry(self.row)
self.form_entries.append(ent)
...
then you can run through all the entries in create_list, but you may consider using a dict instead of a list if the order is going to change in any way
lofty wyvern
Thank you, I'll dig into this now. Thank you so much!

Would anyone know how to create a nested layout with QBoxlayout. I am trying to make a button when pressed that opens up a calculator. The problem with this and I do not know how to make another popup.
silk basin
I am running into an issue that I cannot create another QVBoxLayout
eager beacon
Whats stopping you from doing that?
silk basin
let me grab the error code hold up
eager beacon
okay
is it the one that says you cant add a layout to a widget with a layout?
or something like that?
eager beacon
you're using setLayout to get that error?
silk basin
yeah
eager beacon
try addChildLayout
silk basin
ohh bet. give me a second
eager beacon
are you trying to get the calculator to appear in a new window or in one of the columns in the screenshot above?
silk basin
in a new window
silk basin
I haven't actually. What widget?
silk basin
Oh i see, okay let me see if the addChildLayout is going work. I deleted the code so gimme a second
eager beacon
sure
silk basin
@eager beacon
def showBox(self):
layout = QVBoxLayout()
layout.addWidget(self.c)
layout.addChildLayout(layout)
wait
silk basin
I have to addChildLayout to the original layout
eager beacon
l1 = QVBoxLayout()
row1 = QHBoxLayout()
l1.addChildLayout(row1)
you would add rows of buttons to the row layouts
silk basin
oh I see. but Still nothing pops up when I click my temporary button which calls showBox(self)
eager beacon
use a dialog?
silk basin
I added a print statement and the button is calling the function
silk basin
I'll be honest very new to Python so I am not sure what exec_() even is
eager beacon
its a method of the QDialogue
eager beacon
!paste
proven basinBOT
silk basin
oh wow
so yeah this is controlling what I call the bottom bar of the program
Temporary button which is calling my showBox function
eager beacon
ok
so in showBox you need to create a widget
then set a layout on that widget
that would be the vBox
then add hBoxes to the vbox with addChildLayout
but I'd still argue that you should go with a grid layout
its entire purpose is to do what you want to do
silk basin
def showBox(self):
print("T")
l1 = QVBoxLayout()
row1 = QHBoxLayout()
c1 = QPushButton("c", self)
l1.addWidget(c1)
l1.addChildLayout(row1)
Yeah that still doesn't work for some reason
I also agree with you. Once I get a popup I'll switch
I notice addChildLayout is part of the QLayout class. Would that have anything to do with it
silk basin
Holy hell that worked
eager beacon
you cant view a layout without a widget to contain it
silk basin
That makes so much sense
@eager beacon I bestow upon you a cookie, as gift for your time and effort. πͺ

hello, is this the right channel for tkinter questions?
agile socket
hey how to add amzing gui to pyqt
like the ones in qt designer are stock designs
how to add our own designs
if u have answer pls dm me
gaunt saffron
hey guys, how do you make modern looking GUIs in pyQt5
and is there a way to add dynamic images
bronze basin
@gaunt saffron yes there is through learning and getting good at design
also if you mean gifs yes you can add gifs
gaunt saffron
@bronze basin I mean like any modules that I could use. And by dynamic images i mean like dynamic wallpapers that move based on user interaction.
bronze basin
maybe you would use Qpainter for that but not entirely sure
digital rose
does anyone know what specs do i give a virtual machine to run linux?
static cove
@digital rose that's not python related or user-interface related. Give it the minimum required unless you're planning on running something that requires more resources. It's a VM, you can always recreate it or allocate it more resources later.
static cove
there isn't really a proper channel for a non-python question on a python server. Maybe off-topic? But again, just give it the minimum required and get on with it.
digital rose
ok...... :)))
real parcel
anybody who works with wxpython have any tips for speeding things up/getting smoother rendering results for things like resizing your window and stuff? i'm working on an image viewer and it's going well but repainting a large image during any frame resize events is kind of stuttery
digital rose
i thought that this is related to UIs and OSs so i asked.......
static cove
The channel topic: "For help relating to Python User Interface libraries (e.g. PyQT, Tkinter, WxPython, Curses, PySide)"
Setting up a linux VM does not fit that channel description
digital rose
sorry........ π¦
static cove
@real parcel are you using double buffer?
real parcel
@static cove it didn't seem to help. idk
it's weird; like the graphics of the window appear to be ghosting while the window is resizing
i'm sure i'm doing something wrong but i dunno what. what should i be sure i'm doing in the paint event?
to clear the background i mean
i'm guessing that's the issue
like, that the background isn't clearing properly or fast enough
real parcel
oh wait ALL my windows in xfce are like that, lmao π
digital rose
in tkinter: .grid or .pack?
real parcel
yeah it looks way better in gnome3. lmao π
static cove
@digital rose I prefer grid, but usually end up using a combo with frames to prevent space manager conflicts
leaden tiger
@static cove do you possibly know how buttons in tkinter work?
spark furnace
what do you call this window?
is is just a popup window?
I want to create a popup window like that which is linked to the main window as you can see in pyqt5
normal plinth
Is anyone online willing to help me with a PyQT5 Qgridlayout() question? I'm getting some funky behavior.
eager beacon
whats the problem?
@normal plinth
@spark furnace thats just a widget that contains a tabWidget and a lineEdit
normal plinth
Basically, every element is showing at position 0,0.
eager beacon
did you specify row/col positions?
normal plinth
I did, 0, 0 through 0,6 but they all stack on top of each other at 0, 0.
When I comment them out, they all show in the same position 1 by 1.
This is the gist
eager beacon
you need to call self.setLayout(self.grid)
you are only seeing them because you assigned Window as the parent of the buttons'
if you removed the self argument from the buttons they wouldnt even be visible
normal plinth
When I do that, I'm getting an error "QWidget::setLayout: Attempting to set QLayout "" on Window "", which already has a layout", but you've definitely made it easier for me to diagnose.
Thank you Chris! You should start a YT channel and a Patreon, lol
eager beacon
hah
You are using a mainWindow
and it has whats called a centralWidget
so you need to set a centralWidget
then set a layout on that widget
and add things to that
instead of directly to the mainWindow
normal plinth
Okay, so my layout grid will be contained inside the central widget, which will be contained in the main window.
eager beacon
exactly,
w =QWidget()
self.setCentralWidget(widget)
sets the centralWidget
somber halo
if any1 is listening PLZZZZ HELP ME OUT...i need to know how to correctly embedda pie chart in tkinter gui and update its values on the run with a button.PLZZZ HELPπ’ π’
plz dm if possible
spark furnace
@eager beacon But how do you make the widget popup
eager beacon
connect the buttons clicked signal to the widgets show()
that one is popping up right above the button it looks like
so they are also mapping a position to have it appear in that position
normal plinth
I'll reading up on the mainwindow/central widget to see how best to structure it. Thanks for the help!
bronze basin
@spark furnace hide the widget and when something happens show it?
or make a new window in case you need to use the space in which the popup will show
dark gulch
hi does anyone know if tkinter message boxes work in python 1.8.3
on every documentation site if have seen it says they are a thing
Im getting an error that basically is saying they dont exist
static cove
@leaden tiger I do mostly, are you having an issue with buttons?
ruby pawn
Hey guys, I have some problem with my PySide2 application messing up when I dock it in Autodesk Maya. Any helpful tips to figure this out?
eager beacon
How many of the AUTO bars should be visible?
@ruby pawn I've seen similar things happen to widgets if you have a minimum width or height larger than the maximum
ruby pawn
It's supposed to look like this
But it also makes this bug
Can it be because the minimumHeight is shorter than sizeHint height?
eager beacon
sounds plausible but I'm not positive one way or another
ruby pawn
I'll give it a shot in a moment
If that is indeed the problem. I guess the damn scroll area strikes again
eager beacon
is the gap on the right side happening because that where the vertical scrollBar is?
ruby pawn
Which gap?
eager beacon
Maybe maya has some weird dockWidget policies
eager beacon
like, nothing goes out to the edge
ruby pawn
And they rewrite the .show() command
eager beacon
its like there is a scroll bar there but its been hidden but not removed
ruby pawn
To create a new widget that they slam your UI into
This is what it looks like with a scroll bar btw
Anyway. I have posted on the Maya Programming forum, to see if any of those people have an idea what I've done to misplease the Maya Gods
eager beacon
yeah, Nuke does the same sort of stuff and it also enforces arbitrary rules for some things that can't be modified by the user
ruby pawn
If I mouse over anything button that has a :hover stylesheet thing, it redraws the button in the right place. Like wtf
eager beacon
oh
ruby pawn
Thank god I've only ever had to do a few yes/no dialog boxes in Nuke
eager beacon
try calling update or repaint then
ruby pawn
On which widget
ruby pawn
I don't even know which one is the container anymore
Like after doing the maya docking
eager beacon
hah
ruby pawn
It puts the QDialog into a QWidget
That has a QSplitter above it
That has a QTabWidget above it
That has, another freaking QWidget above it
eager beacon
gotta have a pretty property panel!
eager beacon
update calls repaint
ruby pawn
I have found an event call that happens most of the times I dock it, it doesn't seem 100% reliable but oh well
eager beacon
so w/e
eager beacon
maybe you can save and restore the geometry?
timer on the repaint? I'd just do it on w/e signal fires when docking or undocking]
since that's when the issue appears
ruby pawn
Alright I've tried to call updateGeometry() on all QObject from QDialog and up
Nothing changed
eager beacon
did the repaint work?
I'm assuming thats whats triggering the update as you mouseover and the enterEvent is fired
ruby pawn
Oh I can try repaint()
2 sec
Nope
No luck
Destroying the UI and doing .show() again does fix the issue
Or resizing the window fixes it
But I can't seem to do it with code
eager beacon
calling resize manually doesn't change it?
ruby pawn
Maybe I'm not trying to resize on the right widget
eager beacon
just for the sake of testing start on the inner most widget and if it has children resize them otherwise resize the widget
then move on to its parent and to the same thing
resizing widgets to the current size would probably be fine
or start with the thing that inherits the mixin and resize all of its children and childrens children
ruby pawn
Okay here's a weird thing, if I repaint on a button click. It fixes everything but the scroll area
Like wut
Oh my god
It literally is the scroll area fucking everything up
If I don't have the scroll area, no bugs what so ever
Or well no I'm being an idiot. Sorry.
It's the maya expansion thingies
The maya expansion thingies inside the scroll area is doing it
I'll try to add them back but remove the scroll area to confirm
Yup
It's the fucking maya group box things. FUCK
I will find another solution than the weird group boxes. Thanks for your help troubleshooting again @eager beacon it is much appreciated as always
leaden tiger
@static cove yes, i am using the buttons by importing an image by path over an object. i want after a click to change the image, is that possible?
static cove
Click in a specific spot or just a click in general?
leaden tiger
@kutiekatj, just click in general. i programme my first python programme in python and tkinter. its a card game. i can send you the code what i am doing to import the image?
eager beacon
@ruby pawn you might try throwing this into Maya to see if it behaves correctly https://stackoverflow.com/a/52617714
its a similar situation to what you have going on with scroll area contained in a dock
you might have to throw a verticalSpacer in under the scrollArea to get the behavior you want though
ruby pawn
This is creating a collapsible box from scratch no?
eager beacon
yes
static cove
@leaden tiger So you want to look into bindings then. https://effbot.org/tkinterbook/tkinter-events-and-bindings.htm
You can find a function to the user clicking in a window. That function can then change the picture.
ruby pawn
Thanks for the resource, but I don't think I want to bother creating my own collapsible boxes. I was only using them to stay within the maya design language. If necessary I'll find another way of containing more options while keeping the UI footprint small. Such as tabs.
eager beacon
you could also consider using collapsible layouts instead of a resizing the widget
leaden tiger
@static cove do you mean command binding?
ruby pawn
Maya uses these tabs, so that is my back up plan.
But I found out that the issue with the collapsible box is the way I add content to them. Apparently getting the Qt object, querying the layout and adding a widget is not okay with Maya.
eager beacon
I don't remember where I stole this from but I've used it in place of what you're doing before and didn't run into any of the issues you've seen
ruby pawn
Or I might go with menuItems.
static cove
@leaden tiger yes, you can bind the user pressing their mouse or specific keys to a specific command and the command can be a function you write.
eager beacon
leaden tiger
@static cove i have already done that ... my problem is the following
global playerTwoCard1
newcard = stack.pop()
img = Image.open(newcard.bgpath)
img_resize = img.resize((150,300),Image.ANTIALIAS)
newimage = ImageTk.PhotoImage(img_resize)
playerTwoCard1 = Button(root,image=newimage,command = lambda: player2click(1))
playerTwoCard1.image = newimage
playerTwoCard1.grid(row=0,column=0)
how do i get the newcard.bgpath to newcard.imgpath after a click?
eager beacon
the tabs might be an okay solution if you don't need to constantly swap between them to use your plugin
ruby pawn
Oh no, it'll be like once in a blue moon
eager beacon
sounds like that might be the way to go
ruby pawn
Problem with tabs is the height of the app is defined by which ever tab that is tallest
I did write some code that auto resize them but.. It wasn't amazing
eager beacon
I had to make some shelf things for Maya a couple of years ago and it was a pain so I get where you're coming from
ruby pawn
So I might make a main window and add menu items where you can switch the widget in the main window
eager beacon
I'd say just go with the easiest solution at this point
eager beacon
sounds reasonable
ruby pawn
I was supposed to do a pipeline internship at a VFX studio
But the studio is dissolving
eager beacon
but so did the collapsible boxes lol
ruby pawn
So they just let me do my own shit
eager beacon
are you in LA?
ruby pawn
No, Copenhagen
eager beacon
ahh, all of the VFX work over here is pretty much exclusively in LA and they don't like people working remotely but if they did I'd love to be a TD
ruby pawn
A few people I know went to LA
Mostly animators though
But most people here do London or Copenhagen
eager beacon
makes sense. London has a bunch of studios
static cove
@leaden tiger I don't see the code that captures the user clicking
ruby pawn
Oh we're definitely filling up this chat, I feel bad
leaden tiger
@static cove it should look like this for the first card
def player1click(chosen_card):
global round
global stack
global playerOneCard1

playerOneCard1.grid(row=1,column=1)
if round == 3:
newcard = stack.pop()
img = Image.open(newcard.imgpath)
img_resize = img.resize((150,300),Image.ANTIALIAS)
newimage = ImageTk.PhotoImage(img_resize)
playerOneCard1 = Button(root,image=newimage,command = lambda: player1click(1))
playerOneCard1.image = newimage

elif chosen_card == 5:

round = 1
@static cove but i am thinking about to skip playervsplayer and just write a random card for playervscomputer and dont change backgrounds
@static cove but when the computer plays a background card i need to switch the bgpath to imgpath too ... so no difference
@static cove i am looking for something like playerOneCard1.method(object.value) ... does something like this for a button exists?
or is it better to programme that with pygame?
because i have also recognized, that the code stops running after clicking and dont get back to the function before?
trim ibex
in pyqt5, how do i hide a specific menu item; not a whole menu, but one item in it
dark gulch
does anyone know how to make it so you dont have to use a button to print a listbox selection
I bound my function to mouse1 and it does work
but when I use a button somehow it magically does
static cove
@dark gulch can you share the code where you bind mouse1?
fluid tinsel
is there a way to install pyside2 on Python 3.8?
static cove
It should work for 3.8
fluid tinsel
let me try again, since I last tried 2 weeks ago
static cove
pyside version5.14 definitely works for 3.8, but you should make sure you have at least python 3.8.1+
The last release of it was Sept 10, so nothing would've changed since 2 weeks ago
How are you installing it and what OS?
fluid tinsel
Iβve only tried on a repl, which gives me a forbidden error for the version.
The specific version on the repl is 3.8.2.
would it work on Windows 10 python 3.8.5?
static cove
Huh, I don't use repl much. It should work though with win10 and 3.8.5
fluid tinsel
also, is Qt Creator also available (for .ui) on PySide2?
thereβs not much I can find unless it comes with the normal Qt Creator.
static cove
I don't use Qt Creator much, but the .ui should work with PySide2
Huh, looks like it's an issue with poetry/repl.it
Repl.it is specifying for python versions ^3.8, but that means every python version >= 3.8 and <4.0. Pyside2 doesn't work for 3.9 yet
So poetry can't resolve the dependency
Repl.it should probably be using the notation of 3.8.* to get that not to break since 3.9 is so new
fluid tinsel
oh it isnβt a problem then, I can always finish, and except name errors so I can test on the repl first.
static cove
Curious. That could probably be an improvement on poetry's part
It's a bit unintuitive to me that ^3.8 would include 3.9
fluid tinsel
yeah it installed successfully. but are the .ui files generated from Qt Creator for Python same as the CPP ones for pyside?
i mean does pyside2 read the same files as ones made with the CPP qt creator?
eager beacon
There could be some slight differences but it shouldn't be anything visible to a user

import tkinter as tk

Sorry for responding so late
the button works fine
but when I bind the function to mouse 1
I get this
static cove
@dark gulch Change the function definition of SelectFunction to:
def SelectFunction(*args):
Depending on which key you bind it'll pass additional information you can use to what's attached as the callback. You need to make sure you account for it and catch it
The mouse click will pass the coordinates of where the user clicked as an example
*args will catch anything it passes and put it in a tuple for you to use
leaden tiger
@static cove may i ask you ... any idea?
static cove
@leaden tiger Did you check out the link I gave you about bindings and events in tkinter? Your code isn't tracking when a user clicks anywhere, only when they click the button
dark gulch
@static cove thanks so much I was just staring at it for like 2 hours not knowing what to do
leaden tiger
@static cove i read your link, but the binding is like the command which i give on button creation and i still dont know how to access the value of the object in the button
static cove
So I think I'm not fully understanding what you want to do. I thought you wanted to change the picture of some element in your window when the user clicks anywhere their mouse
leaden tiger
@static cove nope
fluid tinsel
wait does pyside2βs license allow creating public applications?
dark gulch
@static cove not to be a bother but how would I use the indices of the selected string in a something
if selection == "(0,)":
selection = "Length"
if selection == "(1,)":
selection = "Width"
if selection == "(2,)":
selection = "Height"
if selection == "(3,)":
selection = "Area"
if selection == "(4,)":
selection = "Volume"
if selection == "(5,)":
selection = "Mass"
I tried this and its weird
It just prints the same stuff
leaden tiger
@static cove i assigned a object from a list to a variable, that variable contains the background and foreground path to images ... i set the foreground path to the button and it shows me the button with the picture but i want to change the foreground to the background ... therefore i need to access the object within the button
@static cove https://cdn.discordapp.com/attachments/263394252292227082/763829846400827432/unknown.png
@static cove maybe with an image its better to understand
dark gulch
are you making a card game?
leaden tiger
@dark gulch yes π
dark gulch
what game?
leaden tiger
its called schnapsen
leaden tiger
no, its spreaded around in our country
dark gulch
your from austria correct?
leaden tiger
yes
static cove
@leaden tiger from what you typed the button only contains the path to the foreground image. It doesn't contain the object with both the foreground and background
dark gulch
Thats cool that its the "national card game". Weird but cool
static cove
@dark gulch where is the "(1,)" coming from? What is selection specifically?
leaden tiger
@static cove ok? how do i need to reprogramme that ... so i can change background and foreground card?
just a second, i give you my code
dark gulch
well curselection assigns selection to the indices of the list box so I thought it would just be a string and I could simply convert it back
leaden tiger
static cove
@dark gulch just try:
if selection == (4,):
no quoted around the specific thing you're checking against
dark gulch
I did but I will try again
Nothing just prints it out
wait
On this site it says it returns a list
so the (5,) is a list?
static cove
(5,) is a tuple
dark gulch
ahhh
static cove
@leaden tiger currently on my phone so it's a bit tough to read that much code. Is it cool if I take a look at it in the morning and get back to you?
leaden tiger
@static cove sure, no problem π ... i set the paste for 1 hour, so just write me if you have time and i send you the code again?
static cove
@dark gulch when you do selection = "Length" what are you trying to do there?
@leaden tiger yeah, I'll ping you tomorrow
dark gulch
Reassign what it prints to Length
leaden tiger
@static cove idk, if pygame is better for creating card games, because i have seen some on their website
static cove
@leaden tiger I think it'd be worth checking out. I think it handles images better than tkinter
dark gulch
In theory when I click on one of the listbox inputs it will come out as what is clicked
leaden tiger
@static cove yeah, thats the point ... i need buttons to click and the code does not run in a while loop π¦
static cove
@dark gulch so you're effectively printing .curselection() right now?
dark gulch
I got it to work @static cove For some reason when I did
global selection
so I just put the entire thing inside the fuction
and it works
static cove
Try this:
your_listbox.get(your_listbox.curselection())
static cove
And print it
dark gulch
But this works
Ill try that
I was trying that earlier
I dont think listbox.get is a thing
static cove
That'll prevent you from writing the 'if selection == (5,):' thing
dark gulch
oh
wow
I guess I was just writing it wrong bc I tried to do this earlier bc I knew it would work bc for every other widget it did
Thanks
