Detailed Description

Object look-and-feel class.

Library: ilvadvgdt

The predefined object look-and-feel handlers of the matrix gadget are subclasses of this class. It defines several methods of the base class that are common to all predefined looks.

		const IlvRegion *	clip
	)		const

virtual

Is called to draw the background of a matrix.

Parameters

matrix	The matrix.
dst	The destination port.
t	The transformer.
clip	The clipping region.

Implements IlvMatrixLFHandler.

◆ drawFrame()

virtual void IlvDefaultMatrixLFHandler::drawFrame	(	const IlvMatrix *	matrix,
		IlvPort *	dst,
		const IlvTransformer *	t,
		const IlvRegion *	clip
	)		const

virtual

Is called to draw the frame of a matrix.

Parameters

matrix	The matrix.
dst	The destination port.
t	The transformer.
clip	The clipping region.

Implements IlvMatrixLFHandler.

◆ drawItem()

virtual void IlvDefaultMatrixLFHandler::drawItem	(	const IlvMatrix *	matrix,
		IlvPort *	dst,
		IlUShort	colno,
		IlUShort	rowno,
		const IlvRect &	itembbox,
		const IlvRect &	clip
	)		const

virtual

Is called to draw a matrix item.

Parameters

matrix	The matrix.
dst	The destination port.
colno	The column number.
rowno	The row number.
itembbox	The rectangle where to draw the item.
clip	The clipping rectangle.

Implements IlvMatrixLFHandler.

Reimplemented in IlvMatrixCSSLFHandler.

◆ getInsensitivePalette()

virtual const IlvPalette* IlvDefaultMatrixLFHandler::getInsensitivePalette	(	const IlvMatrix *	,
		const IlvAbstractMatrixItem *	item
	)		const

virtual

Returns the palette used to draw the selection in the matrix.

Parameters

matrix	The matrix.
item	Matrix item that the palette is used for. CSS look and feel specific, allows different style for each item. if set null, matrix style is used. Classic look and feel handlers ignore the parameter.

Returns: IlvPalette used to draw the relief in the matrix.

Implements IlvMatrixLFHandler.

Reimplemented in IlvMatrixCSSLFHandler.

◆ getReliefPalette()

virtual const IlvPalette* IlvDefaultMatrixLFHandler::getReliefPalette	(	const IlvMatrix *	,
		const IlvAbstractMatrixItem *	item
	)		const

virtual

Returns the palette used to draw the relief in the matrix.

Parameters

matrix	The matrix.
item	Matrix item that the palette is used for. CSS look and feel specific, allows different style for each item. if set null, matrix style is used. Classic look and feel handlers ignore the parameter.

Returns: IlvPalette used to draw the relief in the matrix.

Implements IlvMatrixLFHandler.

Reimplemented in IlvMatrixCSSLFHandler.

◆ getWindowBackground()

virtual const IlvPalette* IlvDefaultMatrixLFHandler::getWindowBackground ( const IlvMatrix * matrix ) const

virtual

Returns the palette used to draw the background of the matrix.

Parameters

matrix The matrix.

Returns: The palette used to draw the background of the matrix.

Implements IlvMatrixLFHandler.

◆ handleMatrixEvent()

virtual IlBoolean IlvDefaultMatrixLFHandler::handleMatrixEvent	(	IlvMatrix *	matrix,
		IlvEvent &	event
	)		const

virtual

Is called to handle the events of a matrix.

Parameters

matrix	The matrix.
event	The event to handle.

Returns: IlTrue if the event has been consumed.

Implements IlvMatrixLFHandler.

◆ itemBBox()

virtual void IlvDefaultMatrixLFHandler::itemBBox	(	const IlvMatrix *	matrix,
		IlUShort	col,
		IlUShort	row,
		IlvRect &	r,
		const IlvTransformer *	t
	)		const

overridevirtual

Calculates matrix item bounding box.

Parameters

matrix	The matrix.
col	Column
row	Row
r	Rect of item bbox
t	Transformer

Implements IlvMatrixLFHandler.

Reimplemented in IlvMatrixCSSLFHandler.

◆ stylePalette()

virtual const IlvPalette* IlvDefaultMatrixLFHandler::stylePalette	(	const IlvPalette *	base,
		const IlvMatrix *	matrix,
		const IlvAbstractMatrixItem *	item
	)		const

virtual

Adds look and feel styling to a palette. CSS look and feel specific, allows different style for each matrix item. Classic look and feel handlers return the palette unmodified.

Parameters

base	The palette that will be used as a base (default)
matrix	The matrix.
item	Matrix item that the palette is used for.

Returns: IlvPalette with styling.

Implements IlvMatrixLFHandler.
