QAction::QAction(const QString &text ,QObject *parent)
。。。。。。
If parent is an action group the action will be automatically inserted into the group.
这里的action group是指什么啊?能举个例子么?
The action uses a stripped version of text (e.g. "&Menu Option..." becomes "Menu Option") as descriptive text for toolbuttons.
这里的stripped version指什么啊?
谢谢
