This class is not used on its own. Instead it is used to derive other complex control options, for example QStyleOptionSlider and QStyleOptionSpinBox .
齣於性能原因,有很少成員函數,且對成員變量的訪問是直接的 (即:使用
.
or
->
operator). This makes the structures straightforward to use and emphasizes that these are simply parameters used by the style functions.

This enum is used to hold information about the type of the style option, and is defined for each QStyleOption 子類。
| 常量 | 值 | 描述 |
|---|---|---|
QStyleOptionComplex::Type
|
SO_Complex
|
提供樣式選項的類型 ( SO_Complex 對於此類)。 |
類型內部使用通過 QStyleOption ,其子類,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.

This enum is used to hold information about the version of the style option, and is defined for each QStyleOption 子類。
| 常量 | 值 | 描述 |

版本的使用通過 QStyleOption 子類以實現擴展在不破壞兼容性的情況下。若使用 qstyleoption_cast (),通常不需要校驗它。

Constructs a QStyleOptionComplex of the specified type and version , initializing the member variables to their default values. This constructor is usually called by subclasses.
