The QStyleOptionViewItemV4 class is used to describe the parameters necessary for drawing a frame in Qt 4.4 or above.
QStyleOptionViewItemV4 inherits QStyleOptionViewItemV3.
An instance of the QStyleOptionViewItemV4 class has type SO_ViewItem and version 4. The type is used internally by 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 QStyleOption subclass and your own styles. 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.
See QStyleOptionViewItemV3's detailed description for a discussion of how to handle "V3" classes.

This enum is used to represent the placement of the item on a row.
This can be used to draw items differently depending on their placement, for example by putting rounded edges at the beginning and end, and straight edges in between.
