继承者： QStyleOptionFrameV3
PySide.QtGui.QStyleOptionFrameV2 class is used to describe the parameters necessary for drawing a frame in Qt 4.1 or above.
PySide.QtGui.QStyleOptionFrameV2 继承 PySide.QtGui.QStyleOptionFrame which is used for drawing several built-in Qt widgets, including PySide.QtGui.QFrame , PySide.QtGui.QGroupBox , PySide.QtGui.QLineEdit ，和 PySide.QtGui.QMenu .
An instance of the PySide.QtGui.QStyleOptionFrameV2 class has type SO_Frame 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.QStyleOptionFrame and PySide.QtGui.QStyleOptionFrameV2 . One way to achieve this is to use the PySide.QtGui.QStyleOptionFrameV2 copy constructor. For example:
option = QStyleOptionFrame()
if isinstance(option, QStyleOptionFrameV2):
frameOptionV2 = QStyleOptionFrameV2(option)
# draw the frame using frameOptionV2
In the example above: If the frameOption ‘s version is 1, QStyleOptionFrameV2.FrameFeature is set to None for frameOptionV2 。若 frameOption ‘s version is 2, the constructor will simply copy the frameOption ‘s QStyleOptionFrameV2.FrameFeature 值。

构造 PySide.QtGui.QStyleOptionFrameV2 对象。
构造 PySide.QtGui.QStyleOptionFrameV2 copy of the other style option which can be either of the PySide.QtGui.QStyleOptionFrameV2 or PySide.QtGui.QStyleOptionFrame 类型。
若 other style option's version is 1, the new style option's QStyleOptionFrameV2.FrameFeature value is set to QStyleOptionFrameV2.None . If its version is 2, its QStyleOptionFrameV2.FrameFeature value is simply copied to the new style option.
