qmenu

问题 My application has a QMenuBar with a number of QMenu s, each of which having a number of QAction s and sub- QMenu s.

Why can't I have more than one instances of QAction ? Is there any trick to achieve this? I was trying to clone/create a new action with all the propeties of previous action. But I don't know the way to

问题 I'm doing an app with in GUI written with PySide . I set a QMenu on a QPushButton , added several QActions via QMenu.addAction .

问题 I'm working on a Qt application (in C++). Without appyling any styles, my menu looks like this: I'd like it to look like this: How do I achieve this? Either using qss, or programmatically?
