## Detailed Description

The QStyleOptionFrameV3 class is used to describe the parameters necessary for drawing a frame in Qt 4.1 or above.

QStyleOptionFrameV3 inherits QStyleOptionFrameV2

An instance of the QStyleOptionFrameV3 class has type SO_Frame and version 3. 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.

See also QStyleOptionFrameV2 and QStyleOption.
