QGlWidget全屏无菜单 [英] QGlWidget fullscreen no menu

问题描述

我有一个应用程序，它是单个QGlwidget，并在需要时创建了右键单击QMenu.
数据绘制在重写的paintEvent()

I have an app that is a single QGlwidget with a right-click QMenu created when needed.
The data is drawn in an overridden paintEvent()

但是在全屏模式下不会显示菜单. 我最好将QGraphicsScene作为父窗口，将QGlWidget作为唯一的子窗口吗?

But in fullscreen mode the menu isn't displayed. Am I better having a QGraphicsScene as the parent window and a QGlWidget as the sole child?
