QContextMenuEvent ¶

概要 ¶

详细描述 ¶

Context menu events are sent to widgets when a user performs an action associated with opening a context menu. The actions required to open context menus vary between platforms; for example, on Windows, pressing the menu button or clicking the right mouse button will cause this event to be sent.

当此事件发生时，通常展示 QMenu 带上下文菜单，若这与上下文有关。

Context menu events contain a special accept flag that indicates whether the receiver accepted the event. If the event handler does not accept the event then, if possible, whatever triggered the event will be handled as a regular input event.
