PySide.QtGui.QStyleOptionTabBarBase class is used to describe the base of a tab bar, i.e. the part that the tab bar usually overlaps with.
PySide.QtGui.QStyleOptionTabBarBase contains all the information that PySide.QtGui.QStyle functions need to draw the tab bar base. Note that this is only drawn for a standalone PySide.QtGui.QTabBar (one that isn't part of a PySide.QtGui.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 functions.

This enum is used to hold information about the version of the style option, and is defined for each PySide.QtGui.QStyleOption 子类。
| 常量 | 描述 |
|---|---|
| QStyleOptionTabBarBase.Version | 1 |
The version is used by PySide.QtGui.QStyleOption subclasses to implement extensions without breaking compatibility. If you use qstyleoption_cast() , you normally do not need to check it.

QStyleOptionTabBarBase.StyleOptionType
This enum is used to hold information about the type of the style option, and is defined for each PySide.QtGui.QStyleOption 子类。
| 常量 | 描述 |
|---|---|
| QStyleOptionTabBarBase.Type | The type of style option provided ( SO_TabBarBase for this class). |
The type is used internally by PySide.QtGui.QStyleOption , its subclasses, and 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 PySide.QtGui.QStyleOption subclass and your own styles.
