See the documentation for classQDecoration for a detailed description. This subclass ofQDecoration provides standard icons for the decoration regions.

Note that this class is non-portable and only available inQt for Embedded Linux.

Member Function Documentation

QDecorationDefault::QDecorationDefault()

Default constructor.

[virtual]QDecorationDefault::~QDecorationDefault()

The constructor deletes the static pixmaps.

[virtual]bool QDecorationDefault::paint(QPainter * painter, constQWidget * widget,int decorationRegion = All,DecorationState state = Normal)

Reimplemented fromQDecoration::paint().

Paints the border and title decoration for the top-levelwidget using thepainter provided and the decorationstate. The value ofdecorationRegion is a combination of the bitmask values of enumDecorationRegion.

Note that Qt for Embedded Linux expects this function to return true if any of the widget's decorations are repainted; otherwise it returns false.

[virtual protected]void QDecorationDefault::paintButton(QPainter * painter, constQWidget * widget,int buttonRegion,DecorationState state, constQPalette & palette)

Paints a region of the top-levelwidget. The region is painted in the specified decorationstate using thepainter andpalette provided. The region to be painted is specified bybuttonRegion, which is a combination of the bitmask values ofDecorationRegion. If the value ofbuttonRegion is one ofHelp,Menu,Close,Minimize,Maximize, andNormalize, the button pixmap for that region is painted.

See alsopixmapFor().

[virtual protected]QPixmap QDecorationDefault::pixmapFor(constQWidget * widget,int decorationRegion,int & xoff,int & yoff)

Returns a pointer to theQPixmap for the widget specified bywidget anddecorationRegion. The returnedQPixmap is constructed from the default X pixmap obtained fromxpmForRegion().

xoff andyoff specify the offset for the pixmap.

The value ofdecorationRegion must be one of a subset of the values of enumDecorationRegion. The supported values areHelp,Menu,Close,Minimize,Maximize, andNormalize. Other values ofdecorationRegion return 0.

See alsoQDecoration::DecorationRegion.

[virtual]QRegion QDecorationDefault::region(constQWidget * widget, constQRect & rect,int decorationRegion = All)

Reimplemented fromQDecoration::region().

Returns the region specified bydecorationRegion for the top-levelwidget.rect specifies the rectangle the decoration wraps. The value ofdecorationRegion is a combination of the bitmask values of enumDecorationRegion.

[virtual protected]int QDecorationDefault::titleBarHeight(constQWidget * widget)

Returns the title bar height in pixels for the givenwidget. It is the greater of 20, or the sum of the application font's line spacing value plus a border width fudge factor.

[virtual protected]constchar ** QDecorationDefault::xpmForRegion(int region)

Returns a pointer to the X pixmap for the icon specified byregion. An X pixmap is an ASCII-text-based image. The value ofregion must be one of a subset of the values of enumDecorationRegion. The supported values areHelp,Menu,Close,Minimize,Maximize, andNormalize. Other values ofregion cause zero to be returned.
