PySide.QtGui.QStyleOptionMenuItem class is used to describe the parameter necessary for drawing a menu item.
PySide.QtGui.QStyleOptionMenuItem contains all the information that PySide.QtGui.QStyle 函数需要绘制菜单项从 PySide.QtGui.QMenu 。它还用于绘制其它相关菜单 Widget。
For performance reasons, the access to the member variables is direct (i.e., using the . or -> operator). This low-level feel makes the structures straightforward to use and emphasizes that these are simply parameters used by the style functions.
