继承者： QStyleOptionTabV3
PySide.QtGui.QStyleOptionTabV2 class is used to describe the parameters necessary for drawing a tabs in Qt 4.1 or above.
An instance of the PySide.QtGui.QStyleOptionTabV2 class has type SO_Tab and version 2. 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.
If you create your own PySide.QtGui.QStyle subclass, you should handle both PySide.QtGui.QStyleOptionTab and PySide.QtGui.QStyleOptionTabV2 . One way to achieve this is to use the PySide.QtGui.QStyleOptionTabV2 copy constructor. For example:
if isinstance(option, QStyleOptionTabV2):
tabV2 = QStyleOptionTabV2(option)
# draw the tab using tabV2
In the example above: If tabOption ‘s version is 1, the extra member ( iconSize ) will be set to an invalid size for tabV2 。若 tabOption ‘s version is 2, the constructor will simply copy the tab ‘s iconSize .

构造 PySide.QtGui.QStyleOptionTabV2 .
构造 PySide.QtGui.QStyleOptionTabV2 copy of the other style option which can be either of the PySide.QtGui.QStyleOptionTabV2 or PySide.QtGui.QStyleOptionTab 类型。
If the other style option's version is 1, the new style option's iconSize is set to an invalid value. If its version is 2, its iconSize value is simply copied to the new style option.
构造副本为 other 样式选项。
This enum is used to hold information about the version of the style option, and is defined for each PySide.QtGui.QStyleOption 子类。
