c++ - Qt中的弹出菜单事件控件

Question

当我在Qt中添加弹出菜单如下:

QMenu menu(widget);
menu.addAction("AAA");
menu.exec(eventPress->globalPos());

我如何控制“AAA” Action 事件。例如单击“AAA” 时执行某些操作。

Answer 1

您可以重载 addAction。

From Qt assistant
This convenience function creates a new action with the text text and an optional shortcut shortcut. The action's triggered() signal is connected to the receiver's member slot. The function adds the newly created action to the menu's list of actions and returns it.

MyClass::Popup()
{
QMenu menu(widget);
menu.addAction("AAA", this, SLOT(burnCase()));
menu.exec(eventPress->globalPos());
}

// This is your slot
MyClass::burnCase()
{

}
