Qt for Python

@anoop1 As I said, how do you expect Python's Cmd.cmdloop to interact with Qt's event-driven system and windows/widgets?

That won't change anything if you are blocking the event loop be it with widgets or QtQuick, you'll have similar issue. I highly recommend to fix the blocking parts so you can more freely change the GUI stack if you really want to.

@Black-Cat See this example https://stackoverflow.com/questions/50413628/using-qlineedit-settext-freezes-the-window-but-background-tasks-works-fine/50415394#50415394

@hachbani said in Access QTableView method from child class: I still don't see how it's relevant So you have said before. Yet, for example, if you did not have the self.invalidateFilter() you show that might have been an explanation. just me trying to reproduce a minimal code for the forum, it is indeed self.MyTableView.setModel(ProxyModel). Then it's not going to be possible to help you, if what you reproduce is not like your real code, as in this case. Best of luck finding someone who can help you from different code from your actual. I'll leave it to others.

@jsulm Thanks i will try to use tour method @JonB i try this, it works Thanks a lot @JonB Now i will do what @jsulm propose i will work withe the qsql

@Black-Cat You gorgot to connect the clicked signal from the new button...

@Mikeeeeee said in how to add qaction to the menu in qtoolbar: the menu appeared automatically This is not magic. You can learn an awful lot by looking at the code generated into the ui....h file (in the debug output folder) from uic. Hopefully you will see how this menu is generated, and how you might access it.

@SGaist said in Signal disconnect fail: Hi, Since you require the use of multiprocess, then you should use the interprocess facility that comes with it. You are right in the part where there's a copy of everything done. I currently have no idea how everything works so fine mixing Qt's signals and slots and Python's multiprocess. Therefore, I highly recommend that you make proper use of interprocess communication rather than rely on the luck that it worked until now. Yep, this the thing, hence I need to use python multiprocessing.Event, which has nothing to do with Qt... What made this confusing is that the Emitter process 'masquerades' as both processes (since it has all code and data to do so), and communicates with itself... :-D

OK, I found out that the issue has something to do with me using setWindowFlags(Qt.X11BypassWindowManagerHint). Does anyone have ideas as to what else to use? (Ideally I don't want an 'X' button on my lock screen, or be able to press Alt+F4 to close it)

Hi , Update sip3_4.19.23.bb recipe version . in my case it was build successfully. Regards, Sateesh

There's a FAQ for the behaviour you saw with the lambda.

Hi The QToolBox is such a collapsible widget but Im not sure we can add a checkbox to its title in any easy way. Its also possible to make the ListWidget collapsible with a bit of house keeping code to handle if its Note row is visible or not.

@Starnomaly In a Command Prompt: set QT_DEBUG_PLUGINS=1 python something.py and look at the end of the diagnostic output for the error and its cause.

Thanks for your reply @SGaist , Indeed, after reading your comment, I searched what this Invalidate means, I added self.setInvalidate() in my Fitlre method. Have a nice day.

Hey thanks! Not sure why I couldn't find this but it works!

Can you provide a minimal runnable script that triggers this ?

There's an example in the QSortFilterProxyModel documentation.

@JonB Man, thanks again really, the newbie I'm on this sort of things, you're saving me. I've looking all over the documentations for the past 3 days to do this. Thanks. It works.

@Mastiff I think How to make QListWidget items editable does what just what you want, and as a bonus it's in Python :)

Solved, thanks, it's my main program's problem :)
