Detailed Description
QStyleOptionTitleBar contains all the information that QStyle functions need to draw the title bar of a QMdiSubWindow.
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.
See also QStyleOption, QStyleOptionComplex, and QMdiSubWindow.
Member Type Documentation
enum QStyleOptionTitleBar::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 |
|---|---|---|
QStyleOptionTitleBar::Type | SO_TitleBar | The type of style option provided (SO_TitleBar 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 QStyleOptionTitleBar::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 |
|---|---|---|
QStyleOptionTitleBar::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.
