Detailed Description

The QStyleOptionViewItemV2 class is used to describe the parameters necessary for drawing a frame in Qt 4.2 or above.

QStyleOptionViewItemV2 inherits QStyleOptionViewItem.

An instance of the QStyleOptionViewItemV2 class has type SO_ViewItem and version 2. 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 QStyleOptionFrameV2's detailed description for a discussion of how to handle "V2" classes.

This enum is used to hold information about the version of the style option, and is defined for each QStyleOption subclass.

Constant Value Description
QStyleOptionViewItemV2.Version 2 2

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.

QStyleOptionViewItemV2.ViewItemFeature

This enum describes the different types of features an item can have.

Constant Value Description
QStyleOptionViewItemV2.None 0x00 Indicates a normal item.

Constructs a QStyleOptionViewItemV2 object.

QStyleOptionViewItemV2.__init__ (self, QStyleOptionViewItemV2 other)

Constructs a copy of other.

QStyleOptionViewItemV2.__init__ (self, QStyleOptionViewItem other)

Constructs a QStyleOptionViewItemV2 copy of the other style option which can be either of the QStyleOptionViewItemV2 or QStyleOptionViewItem types.

If the other style option's version is 1, the new style option's ViewItemFeature value is set to QStyleOptionViewItemV2.None. If its version is 2, its ViewItemFeature value is simply copied to the new style option.
