As far as I can remember, a lot of the classes like that expose details of
Designer's implementation without really providing a convenient way to extend
Designer itself, other than by using a custom widget plugin (or another type
of plugin) as a way of running the code you want to extend Designer with.
It looks like Designer passes a QDesignerFormEditorInterface instance to your
plugins's initialize method:
You can then call its formWindowManager method to get a
Then you can access the form windows using the window manager interface:
So, to summarize, in your QPyDesignerCustomWidgetPlugin class, you do
something like this with the initialize method:
windowManager = formEditor.formWindowManager()
for i in range(windowManager.formWindowCount()):
window = windowManager.formWindow(i)
Hope this helps,
