Detailed Description
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, there are few member functions and the access to the member variables is direct (i.e., using the . or -> operator). This makes the structures straightforward to use and emphasizes that these are simply parameters used by the style functions.

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.
See also StyleOptionType.

See also QFrame::lineWidth.
int QStyleOptionGroupBox::midLineWidth
This variable holds the mid-line width for drawing the panel
The mid-line width is usually used when drawing sunken or raised group box frames. The value of this variable is, currently, always 0.
See also QFrame::midLineWidth.
QString QStyleOptionGroupBox::text
