Detailed Description

The QStyleOptionGroupBox class describes the parameters for drawing a group box.

QStyleOptionButton contains all the information that QStyle functions need the various graphical elements of a group box.

It holds the lineWidth and the midLineWidth for drawing the panel, the group box's title and the title's alignment and color.

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.

For an example demonstrating how style options can be used, see the Styles example.
