Detailed Description

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

Since: 4.2

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.

Enumerations

◆ StyleOptionVersion

enum QStyleOptionViewItemV2::StyleOptionVersion

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

Version 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.

◆ ViewItemFeature

enum QStyleOptionViewItemV2::ViewItemFeature

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

None Indicates a normal item.
WrapText Indicates an item with wrapped text.
Alternate Indicates that the item's background is rendered using alternateBase.
HasCheckIndicator Indicates that the item has a check state indicator.
HasDisplay Indicates that the item has a display role.
HasDecoration Indicates that the item has a decoration role.

◆ QStyleOptionViewItemV2() [3/4]

QStyleOptionViewItemV2::QStyleOptionViewItemV2 ( const 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.
