| enum | StyleOptionType { Type } |

QStyleOptionTabWidgetFrame 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 functions.

This enum is used to hold information about the type of the style option, and is defined for each QStyleOption 子類。
