Detailed Description

QStyleOptionSpinBox contains all the information that QStyle functions need to draw QSpinBox and QDateTimeEdit.

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.

For an example demonstrating how style options can be used, see the Styles example.

See also QStyleOption and QStyleOptionComplex.

Member Type Documentation

enum QStyleOptionSpinBox::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
QStyleOptionSpinBox::Type SO_SpinBox The type of style option provided (SO_SpinBox 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 QStyleOptionSpinBox::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
QStyleOptionSpinBox::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.
