Detailed Description

The QStyleOptionButton class is used to describe the parameters for drawing buttons.

QStyleOptionButton contains all the information that QStyle functions need to draw graphical elements like QPushButton, QCheckBox, and QRadioButton.

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.


Type Documentation

QStyleOptionButton.ButtonFeature

This enum describes the different types of features a push button can have.

Constant Value Description
QStyleOptionButton.None 0x00 Indicates a normal push button.
QStyleOptionButton.Flat 0x01 Indicates a flat push button.
QStyleOptionButton.HasMenu 0x02 Indicates that the button has a drop down menu.
QStyleOptionButton.DefaultButton 0x04 Indicates that the button is a default button.

The ButtonFeatures type is a typedef for QFlags<ButtonFeature>. It stores an OR combination of ButtonFeature values.

See also features.

QStyleOptionButton.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
QStyleOptionButton.Type SO_Button The type of style option provided (SO_Button 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.

QStyleOptionButton.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
QStyleOptionButton.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.
