The QStyleOptionFrame class is used to describe the parameters for drawing a frame.
QStyleOptionFrame is used for drawing several built-in Qt widgets, including QFrame , QGroupBox , QLineEdit ,和 QMenu . Note that to describe the parameters necessary for drawing a frame in Qt 4.1 or above, you must use the QStyleOptionFrameV2 子類。
An instance of the QStyleOptionFrame class has type SO_Frame and version 1.
類型內部使用通過 QStyleOption ,其子類,和 qstyleoption_cast () to determine the type of style option. In general you do not need to worry about this unless you want to create your own QStyleOption subclass and your own styles. The version is used by QStyleOption 子類以實現擴展在不破壞兼容性的情況下。若使用 qstyleoption_cast (),通常不需要校驗它。
If you create your own QStyle subclass, you should handle both QStyleOptionFrame and QStyleOptionFrameV2 .
