Detailed Description

\variable QStyleOptionDockWidget::title

the title of the dock window

The default value is an empty string.

\variable QStyleOptionDockWidget::closable

whether the dock window is closable

The default value is true.

\variable QStyleOptionDockWidget::movable

whether the dock window is movable

The default value is false.

\variable QStyleOptionDockWidget::floatable

whether the dock window is floatable

The default value is true.

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.

◆ 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.
