详细描述

The QStyleOptionComplex class is used to hold parameters that are common to all complex controls.

This class is not used on its own. Instead it is used to derive other complex control options, for example QStyleOptionSlider and QStyleOptionSpinBox .

For performance reasons, the access to the member variables is direct (i.e., using the . or -> operator).

成员类型文档编制

enum QStyleOptionComplex:: 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 描述
QStyleOptionComplex::Type SO_Complex 提供样式选项的类型 ( SO_Complex 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 QStyleOptionComplex:: 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 描述
QStyleOptionComplex::Version 1 1

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 (),通常不需要校验它。

成员函数文档编制

QStyleOptionComplex:: QStyleOptionComplex ( int version = QStyleOptionComplex::Version, int type = SO_Complex)

构造 QStyleOptionComplex 的指定 type and version , initializing the member variables to their default values. This constructor is usually called by subclasses.

QStyleOptionComplex:: QStyleOptionComplex (const QStyleOptionComplex & other )

构造副本为 other 样式选项。
