QGraphicsViewe without any "Frame" in Full screen - how to?

[ademmler]

Hi,

I have a QGraphicsView (including a Scene) in my MainWindow.
Is there a way to "detach" this View and show it Fullscreen without any "frame or other elements" around?
And how to come back to normal view mode?

Thx and regards

Put it in a QDockWidget or in its own (maybe even frameless/borderless) QWidget.

And how to come back to normal view mode?

You have to find a way, since FramelessWindowHint removes all window/frame decorations and shows only the rendered widget itself.
( maybe a QWidget with a layout and your QGraphicsView + some control buttons)

@ademmler QGraphicsView inherits QFrame.
step1: remove it from the current layout
step2: set its parent to nullptr
step3: save its flags and size
step4: set its size to full screen
step5: set flag to show it on the top

reverse these steps when it is set back.
