It is very annoying not to have stacking layout on toolbar of widget application and QStackingWidget has no method setStackingMode(StackAll).
I need buttons on QOpenGLWidget with grid layout on widget application.
What do you suggest?
Then why not use a QStackedLayout ?
I am designing GUI with designer. There isn't Stacked Layout on toolbox.
QStackWidget is built on top of QStackedLayout, so you can access the layout and set the stacking mode on it.
