The QStyleOptionGroupBox class describes the parameters for drawing a group box. More...
|qmake:||QT += widgets|
This class was introduced in Qt 4.1.
For performance reasons, the access to the member variables is direct (i.e., using the
-> 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
This enum is used to hold information about the type of the style option, and is defined for each QStyleOption subclass.
|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.
This enum is used to hold information about the version of the style option, and is defined for each QStyleOption subclass.
