Detailed Description

\variable QStyleOptionToolButton::features

an OR combination of the tool button's features

The default value is \l None.

See also: ToolButtonFeature

\variable QStyleOptionToolButton::icon

the icon for the tool button

The default value is an empty icon, i.e. an icon with neither a pixmap nor a filename.

See also: iconSize

\variable QStyleOptionToolButton::iconSize

the size of the icon for the tool button

The default value is QSize(-1, -1), i.e. an invalid size.

\variable QStyleOptionToolButton::text

the text of the tool button

This value is only used if toolButtonStyle is Qt::ToolButtonTextUnderIcon, Qt::ToolButtonTextBesideIcon, or Qt::ToolButtonTextOnly. The default value is an empty string.

\variable QStyleOptionToolButton::arrowType

the direction of the arrow for the tool button

This value is only used if \l features includes \l Arrow. The default value is Qt::DownArrow.

\variable QStyleOptionToolButton::toolButtonStyle

a Qt::ToolButtonStyle value describing the appearance of the tool button

The default value is Qt::ToolButtonIconOnly.

See also: QToolButton::toolButtonStyle()

\variable QStyleOptionToolButton::pos

the position of the tool button

The default value is a null point, i.e. (0, 0)

\variable QStyleOptionToolButton::font

the font that is used for the text

This value is only used if toolButtonStyle is Qt::ToolButtonTextUnderIcon, Qt::ToolButtonTextBesideIcon, or Qt::ToolButtonTextOnly. By default, the application's default font is used.

The QStyleOptionComboBox class is used to describe the parameter for drawing a combobox.

\inmodule QtWidgets

QStyleOptionButton contains all the information that QStyle functions need to draw QComboBox.

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.

Member Enumeration Documentation

◆ StyleOptionType

enum QStyleOptionComboBox::StyleOptionType

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

\value Type The type of style option provided (\l{SO_ComboBox} 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.

Definition at line 575 of file qstyleoption.h.

◆ StyleOptionVersion

enum QStyleOptionComboBox::StyleOptionVersion

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

\value Version 2

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.
