Qt6 QProxyStyle cause app crash
-
@Christian-Ehrlicher Yeah I do
In general I do something like this
app.setStyle(QStyleFactory.create("fusion")) QPalette pa /*pa set bunch of pa options */ app.setPalette(pa) app.setStyleSheet(""" style stuff""")But the QProxyStyle sheet does not properly clone it. So I'm trying to manually make a new one, assign it and well not cause any mem error... So far I'm failing left and right.

When you create a new style you also have to apply your own palette if you want to same as the app style.

Yes but I can't get it to work.
I apply QStyle, Palette and StyleSheet to my QApp. But how can I properly replicate it ? I tried making a widget and then taking it from widget. But that did not work either. And QProxyStyle wrecks havoc when it gets a style each time. -

Apply the same things to the newly created style.

I can't set styleSheet() on style... So I cant style the Style... o.o

Then don't use this approach and don't delete the proxy style.
-
@Christian-Ehrlicher So I will have memory leak... I have to delete treeview when user changes properties...
-
But why do you have to re-create the style then? Apart from that - why do you need to re-create a treeview widget at all?
-
@Christian-Ehrlicher The app creates content depending on user selection. Different content require different views as well as I can have multiple views for one content... so widgets gets made/deleted on a "normal basis". So deleting widget/treeView is a normal thing. It seems that this issue is even bigger on older OS as win7 just refuses to draw app after these "workarounds" :- (
-
Sorry but I still don't see why you need to delete and re-create the proxy style. But do what you like.
