The QStyleOptionToolBox class is used to describe the parameters needed for drawing a tool box.
QStyleOptionToolBox contains all the information that QStyle functions need to draw QToolBox .
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 函数。
For an example demonstrating how style options can be used, see the 样式 范例。
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 |
|---|---|---|
| QStyleOptionToolBox.Type | SO_ToolBox | The type of style option provided ( SO_ToolBox for this class). |
The type is used internally by QStyleOption , its subclasses, and qstyleoption_cast () 到 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 子类。
| 常量 | 值 | 描述 |
|---|---|---|
| QStyleOptionToolBox.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.
