The QStyleOptionTabWidgetFrameV2 class is used to describe the parameters for drawing the frame around a tab widget.
QStyleOptionTabWidgetFrameV2 contains all the information that QStyle functions need to draw the frame around QTabWidget .
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 函数。
For an example demonstrating how style options can be used, see the 样式 范例。
This enum is used to hold information about the version of the style option, and is defined for each QStyleOption 子类。
| 常量 | 值 | 描述 |
|---|---|---|
| QStyleOptionTabWidgetFrameV2.Version | 2 | 2 |
The version is used by QStyleOption subclasses to implement extensions without breaking compatibility. If you use qstyleoption_cast (), you normally do not need to check it.
