Qt for Python

Thanks for the links !

Any chances you have Python 3.12 for your environment ? If so, downgrade to 3.11. At least pip installation of PyQt6-tools worked with that version of Python.

Can you share how you created your Python environment ? On macOS, with: Python 3.12.0 PySide6 6.6.1 yfinance 0.2.33 No crash happened.

Hi and welcome to devnet, Store the original color before changing it so you can reuse it when you want to reset the color to default.

@JonB said in An advice needed to catch Segmentation Violation: @StarterKit I meant an hour of putting in some print()/logging statements all over the place, then letting it run to reproduce in time. Oh... sorry, got it from second reading only. Agree with you.

@SGaist said in Creating a QComboBox with checkboxes within it: In the context of a menu, having checkboxes is fine as you also have the complete view of the possibilities. In the context of a team of players, I would rather expect to have a list view that I can go up and down at will where I can see what I have selected rather than having to use a combo box that I would need to open and re-open. @JonB said in Creating a QComboBox with checkboxes within it: @rssweiss As @SGaist says use a QListView here. A combobox is intended to pick a single item, not put checks against multiple items. Alright, thank you guys!

@friedemannkleint Thank you. Will try it

Hi, It sounds like a regression then since it used to work. Did you already check the bug report system ? If there's nothing there, then please consider opening a new report with your findings.

@SGaist Got it. Thanks!

@LREGS said in Accurate Button Placement in QDesigner: However, when I'm placing them in QDesigner it's not possible with my current knowledge to place them exactly in the holes of the image because it seems the center of the label needs to be anchored to one of the background dots in QDesigner. This is probably the snap to grid behavior. From the menu toolbar: Tools -> Form Editor -> Form Settings ... Check the Grid checkbox, and then uncheck Snap. @SGaist's suggestions are likely easier to deal with in the long run.

@Joimar said in Using UI class from another directory: from UIClasses\mainwindow import Ui_MainWindow Shouldn't it be from UIClasses.mainwindow import Ui_MainWindow ?

Here is the complete issue: https://bugreports.qt.io/browse/PYSIDE-2547 I got this solution from here: https://stackoverflow.com/questions/38142809/pyqt-5-6-connecting-to-a-dbus-signal-hangs If you have an idea how to get the PropertiesChanged Signal to work, I would be happy, too, otherwise I will switch to GTK I guess... Or maybe I open a separate post for this, but as no one could help on the simple case, I have little hope for the more complex case...

@Salamafet said in [PySide6] QSystemTrayIcon bug when using Class: I don't understand why, but it works. Well the reason is that when Python detects nothing is refencing any Python object it destroys it --- that's the object collection the language gices you unlike plain C++. The mystery is that one would have thought that self.setContextMenu(menu) would itself increment the reference count on menu and its action added to that. I don't know why it does not. I don't know whether menu = QtWidgets.QMenu(self) inside Tray() would have improved the situation. You might like to add that anyway, and then maybe see if the other 2 changes are no longer required. Ah, see (the C++ explanation for) [void]QSystemTrayIcon::setContextMenu(QMenu *menu) (or PySide6 PySide6.QtWidgets.QSystemTrayIcon.setContextMenu(menu)): Note: The system tray icon does not take ownership of the menu. You must ensure that it is deleted at the appropriate time by, for example, creating the menu with a suitable parent object. This explains everything. Whenever it says "something does not take ownership of this QObject" that will mean the Python code will not increment a reference count. setContextMenu() leaves you in charge of the menu, which e.g. you might be using elsewhere. Consequently any QObjects documented like that will require (typically) a Python self._variable = TheObject() to keep it "alive" for the duration of the class instance, not just a local variable. Or, by the looks of it even better, pass self to the top-level object's constructor (your QMenu()) so it is fully owned by the instance.

Hi and welcome to devnet, Can you play this file successfully with ffmpeg ?
