QtDesigner - custom plugin - QWidget not behaving properly - cant add children/layouts.

Dariusz

Hey

I want to extend QWidget, give it some more properties and use it as my base building block.

Sadly when I drag it on the widget form, it seems to be "dull". I can't set layout on it nor add other widgets to it.

As far as I can tell I need https://doc.qt.io/qt-6/qdesignercontainerextension.html but this is for multi page widget, not QWidget from what I can read... any idea what class I need to extend?

Regards

Hi
Do you have

bool YourPlugin::isContainer() const
{
return true;
}

Hey @mrjj
Digging out this topic... as I figure better to stick it in the same tree...

Anyway, any idea how to make QScrollArea behave correctly too? Making it container does not let me drag widgets on it :/
