Detailed Description▲
QStyleOptionTabBarBase contains all the information that QStyle functions need to draw the tab bar base. Note that this is only drawn for a standalone QTabBar (one that isn't part of a QTabWidget).
For performance reasons, there are few member functions and the access to the member variables is direct (i.e., using the . or -> operator). This makes the structures straightforward to use and emphasizes that these are simply parameters used by the style functions.
For an example demonstrating how style options can be used, see the Styles example.

QStyleOptionTabBarBase::Type |
SO_TabBarBase |
The type of style option provided (SO_TabBarBase for this class). |
The type is used internally by 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 QStyleOption subclass and your own styles.
