PySide.QtGui.QStyleOptionHeader class is used to describe the parameters for drawing a header.
PySide.QtGui.QStyleOptionHeader contains all the information that PySide.QtGui.QStyle functions need to draw the item views' header pane, header sort arrow, and header label.
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.

The version is used by PySide.QtGui.QStyleOption subclasses to implement extensions without breaking compatibility. If you use qstyleoption_cast() , you normally do not need to check it.

| 常量 | 描述 |
|---|---|
| QStyleOptionHeader.Type | The type of style option provided ( SO_Header for this class). |
The type is used internally by PySide.QtGui.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 PySide.QtGui.QStyleOption subclass and your own styles.
