详细描述

QStyleOptionSpinBox class is used to describe the parameters necessary for drawing a spin box.

QStyleOptionSpinBox contains all the information that QStyle 函数需要绘制 QSpinBox and QDateTimeEdit .

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.

enum QStyleOptionSpinBox:: StyleOptionType

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

常量	值	描述
`QStyleOptionSpinBox::Type`	`SO_SpinBox`	提供样式选项的类型 ( SO_SpinBox 对于此类)。

类型内部使用通过 QStyleOption ，其子类，和 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.

enum QStyleOptionSpinBox:: StyleOptionVersion

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

常量	值	描述

版本的使用通过 QStyleOption 子类以实现扩展在不破坏兼容性的情况下。若使用 qstyleoption_cast (), you normally do not need to check it.
