Detailed Description

QStyleOptionSpinBox包含QStyle函数绘制QSpinBox和QDateTimeEdit所需的所有信息。
出于性能考虑，对成员变量的访问是直接的(即，使用。或->运算符)。这种低级的感觉使结构易于使用，并强调这些结构只是样式函数使用的参数。
有关演示如何使用样式选项的示例，请参见Styles示例。

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

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.
