context menu 사용시에는 ContextMenuPolicy 를 사용하여 아래의 3가지 방법중 하나를 이용한다.
아무 설정 안하면, 기본적으로 DefaultContextMenu 정책이 사용된다.
<< ContextMenuPolicy 사용하는 3가지 방법 >>
방법 1. DefaultContextMenu
-- contextMenuEvent() 호출함.
방법 2. ActionsContextMenu
-- actions() 사용.
방법 3. CustomContextMenu
-- customContextMenuRequested() signal 발생시킴.
