Detailed Description

The QStyleOptionViewItem class is used to describe the parameters used to draw an item in a view widget.

QStyleOptionViewItem contains all the information that QStyle functions need to draw the items for Qt's model/view classes.

For performance reasons, the access to the member variables is direct (i.e., using the . or -> operator). This low-level feel makes the structures straightforward to use and emphasizes that these are simply parameters used by the style functions.

For an example demonstrating how style options can be used, see the Styles example.

See also QStyleOption and Model/View Programming.

Member Enumeration Documentation

enum QtGui.QStyleOptionViewItem.Position

This enum describes the position of the item's decoration.

See also decorationPosition.

Enumerator:

Bottom	Below the text.
Left	On the left of the text.
Right	On the right of the text.
Top	Above the text.

enum QtGui.QStyleOptionViewItem.StyleOptionType

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

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.

See also StyleOptionVersion.

Enumerator:

Type	The type of style option provided (SO_ViewItem for this class).

enum QtGui.QStyleOptionViewItem.StyleOptionVersion

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

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 also StyleOptionType.

Property Documentation

new Qt.AlignmentFlag QtGui.QStyleOptionViewItem.DecorationAlignment

getset

This variable holds the alignment of the decoration for the item.

The default value is Qt::AlignLeft.

new QStyleOptionViewItem.Position QtGui.QStyleOptionViewItem.DecorationPosition

getset

This variable holds the position of the decoration for the item.

The default value is Left.

See also Position.

new QSize QtGui.QStyleOptionViewItem.DecorationSize

getset

This variable holds the size of the decoration for the item.

The default value is QSize(-1, -1), i.e. an invalid size.

See also decorationAlignment and decorationPosition.

new Qt.AlignmentFlag QtGui.QStyleOptionViewItem.DisplayAlignment

getset

This variable holds the alignment of the display value for the item.

The default value is Qt::AlignLeft.

new QFont QtGui.QStyleOptionViewItem.Font

getset

This variable holds the font used for the item.

By default, the application's default font is used.

See also QFont.

new bool QtGui.QStyleOptionViewItem.ShowDecorationSelected

getset

This variable holds whether the decoration should be highlighted on selected items.

If this option is true, the branch and any decorations on selected items should be highlighted, indicating that the item is selected; otherwise, no highlighting is required. The default value is false.

See also QStyle::SH_ItemView_ShowDecorationSelected and QAbstractItemView.

new Qt.TextElideMode QtGui.QStyleOptionViewItem.TextElideMode

getset

This variable holds where ellipsis should be added for text that is too long to fit into an item.

The default value is Qt::ElideMiddle, i.e. the ellipsis appears in the middle of the text.

See also Qt::TextElideMode and QStyle::SH_ItemView_EllipsisLocation.
