## Detailed Description

The QStyleOptionToolBoxV2 class is used to describe the parameters necessary for drawing a frame in Qt 4.3 or above.

QStyleOptionToolBoxV2 inherits QStyleOptionToolBox which is used for drawing the tabs in a QToolBox.

An instance of the QStyleOptionToolBoxV2 class has type SO_ToolBox and version 2. 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. 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.

If you create your own QStyle subclass, you should handle both QStyleOptionToolBox and QStyleOptionToolBoxV2.

`QStyleOptionToolBoxV2::NotAdjacent` | `0` | The tab is not adjacent to a selected tab (or is the selected tab).
`QStyleOptionToolBoxV2::NextIsSelected` | `1` | The next tab (typically the tab on the right) is selected.
`QStyleOptionToolBoxV2::PreviousIsSelected` | `2` | The previous tab (typically the tab on the left) is selected.

See also selectedPosition.
