PySide.QtGui.QStyleOptionViewItemV4 class is used to describe the parameters necessary for drawing a frame in Qt 4.4 or above.
PySide.QtGui.QStyleOptionViewItemV4 继承 PySide.QtGui.QStyleOptionViewItemV3 .
An instance of the PySide.QtGui.QStyleOptionViewItemV4 class has type SO_ViewItem and version 4. 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. 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.
