It looks like showFullscreen() and showNormal() have different effects

I want to make a control that can double click on the full screen, and then double click to restore the original.showFullscreen() can be full screen, but showNormal() does not bring it back, it becomes a separate window.fullscreen works 100% ,but getting back to normal widget embedded in another widget ends with flying widget not docked in it's previous location.

        if event_type == event.MouseButtonDblClick and watched == self.ui.label_photo:
            if not flag:
                self.ui.label_photo.setWindowFlag(Qt.Window)
                self.ui.label_photo.showFullScreen()
                flag = True
            else:
                self.ui.label_photo.setWindowFlag(Qt.SubWindow)
                self.ui.label_photo.showNormal()
                flag = False

normal

now

self.ui.label_photo.showNormal()

My guess is: you need to put self.ui.label_photo back to its parent (set the parent again?) and add to parents layout.

parents layout

Thanks, that helped me out. I tried using setParent, but forgot to add it back to the parents layout.
