Detailed Description

QStyleOptionToolButton contains all the information that QStyle functions need to draw QToolButton.

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 QStyleOptionToolButton::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
QStyleOptionToolButton::Type	SO_ToolButton	The type of style option provided (SO_ToolButton 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 QStyleOptionToolButton::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
QStyleOptionToolButton::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.

enum QStyleOptionToolButton::ToolButtonFeatureflags QStyleOptionToolButton::ToolButtonFeatures

Describes the various features that a tool button can have.

Constant	Value	Description
QStyleOptionToolButton::None	0x00	A normal tool button.
QStyleOptionToolButton::Arrow	0x01	The tool button is an arrow.
QStyleOptionToolButton::Menu	0x04	The tool button has a menu.

QStyleOptionToolButton::HasMenu	0x10	The button has a popup menu.
