How to add checkbox to context menu?

midnightdim

@JonB Thanks.
I googled for it of course, and I found the solutions you mention. Note that they inherit QWidgetAction.
My solution is based on the first one, but I'm not sure if I've ported it to Python correctly.

And yes, if I didn't have the requirement for tri-state I could simply use checkable menu actions.

It helps if you reference where you got your code from when asking the question :)

That code uses setDefaultWidget(_widget);, which @mrjj called your attention to. So don't you need self.setDefaultWidget(self.widget)? Hmm, OK, I see he has just changed his comment. Your Python code looks equivalent to the C++ to me. I don't know, unless doing it with setDefaultWidget() is better.

@JonB

OH i miss some many thing with python.

in c++ the virtual function is like
https://doc.qt.io/qt-5/qwidgetaction.html#createWidget

QWidgetAction::createWidget(QWidget *parent)

but his is like
def createWidget(self,text):
return self.widget

so extra text with. WIll this still override the base version ? ( i guess not)

JonB

@mrjj
Yes, good spot, that does indeed look fluffy. Trouble with Python where you don't actually know whether you're overriding anything :(

@midnightdim
(You could put a print() statement into your override to see if it's ever really called.) Follow that advice to change your override method. Or, I don't know, use the setDefaultWidget() like the C++ does instead.

midnightdim

@JonB I actually tested it before, and yes, this override does get called. I'll try to change it to setDefaultWidget().

midnightdim

Thanks @JonB and @mrjj
I added self.setDefaultWidget(self.widget) at the end of the constructor, removed createWidget, and it does work as expected. Cool!

JonB

@midnightdim
Yes, I did wonder why you chose to adopt different code from that example! :)

midnightdim

@JonB I'm not a pro programmer (started Python less than a year ago, have very small experience in C++) and the documentation for PySide6 doesn't look clear to me, also there were no examples for this particular case. So I wasn't sure about setDefaultWidget method in PySide6.
Thanks again.

@danielcharles Why do you post a link to a video handling C#? This is Qt forum...
