Detailed Description

the palette that should be used when painting the controlthe text layout direction that should be used when drawing text in the controlthe font metrics that should be used when drawing text in the controlthe area that should be used for various calculations and paintingthe style flags that are used when drawing the controlthe option type of the style optionthe version of the style optionThe QStyleOptionFocusRect class is used to describe the parameters for drawing a focus rectangle with QStyle.

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 {widgets/styles}{Styles} example.

Member Enumeration Documentation

enum QStyleOptionFocusRect::StyleOptionType

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

Type The type of style option provided ({SO_FocusRect} 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

Reimplemented from QStyleOption.

Definition at line 81 of file qstyleoption.h.

{ Type = SO_FocusRect };

enum QStyleOptionFocusRect::StyleOptionVersion

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

Version 1

The version is used by QStyleOption subclasses to implement extensions without breaking compatibility. If you use qstyleoption_cast(), you normally don't need to check it.
