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.

Member Type Documentation

enum QStyleOptionGroupBox::StyleOptionType

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

Constant	Value	Description
QStyleOptionGroupBox::Type	SO_GroupBox	The type of style option provided (SO_GroupBox 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.

See also StyleOptionVersion.

enum QStyleOptionGroupBox::StyleOptionVersion

This enum is used to hold information about the version of the style option, and is defined for each QStyleOption subclass.

Constant	Value	Description
QStyleOptionGroupBox::Version	1	1

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.
