Detailed Description

Matrix item class.

Library: ilvadvgdt

Use this class to define a matrix item as a floating-point value with a filled background.

See also: IlvMatrix, IlvPalette.

Constructor & Destructor Documentation

◆ IlvFilledFloatMatrixItem() [1/3]

IlvFilledFloatMatrixItem::IlvFilledFloatMatrixItem	(	IlvPalette *	palette,
		IlFloat	value
	)

Constructor.

Initializes a new instance of the class IlvFilledFloatMatrixItem.

Parameters

palette	The matrix item palette.
value	The floating-point value encapsulated by the item.

◆ IlvFilledFloatMatrixItem() [2/3]

IlvFilledFloatMatrixItem::IlvFilledFloatMatrixItem	(	IlvMatrix *	matrix,
		IlFloat	value
	)

Constructor.

Initializes a new instance of the class IlvFilledFloatMatrixItem.

Parameters

matrix	The matrix to which the item belongs. This parameter is used to compute the palette of the item.
value	The floating-point value encapsulated by the item.

◆ IlvFilledFloatMatrixItem() [3/3]

IlvFilledFloatMatrixItem::IlvFilledFloatMatrixItem	(	IlFloat	value,
		IlvPalette *	palette,
		IlvPalette *	invpal
	)

Constructor.

Initializes a new instance of the IlvFilledFloatMatrixItem class.

Parameters

value	The floating-point value encapsulated by the item.
palette	The matrix item palette.
invpal	The inverted palette used by the matrix item when it is selected. When using other constructors, the inverted palette is automatically computed from the matrix item palette.

Member Function Documentation

◆ copy()

virtual IlvAbstractMatrixItem* IlvFilledFloatMatrixItem::copy ( ) const

virtual

Copies this object.

Allocates and returns a copy of this object.

Returns: A copy of the object.

See also: IlvPredefinedMatrixItemIOMembers().

Reimplemented from IlvFloatMatrixItem.

◆ draw()

virtual void IlvFilledFloatMatrixItem::draw	(	const IlvMatrix *	matrix,
		IlUShort	col,
		IlUShort	row,
		IlvPort *	dst,
		const IlvRect &	bbox,
		const IlvRect *	clip
	)		const

virtual

Is called to draw the matrix item.

The default implementation of the method calls IlvAbstractMatrixItem::drawLabel.

Parameters

matrix	The matrix to which the item belongs.
col	The column where the matrix item is located.
row	The row where the matrix item is located.
dst	The destination drawing port.
bbox	The bounding box of the matrix item.
clip	The clipping area.

See also: IlvAbstractMatrix::drawItem, drawLabel().

Reimplemented from IlvAbstractMatrixItem.

◆ getInvertedPalette()

IlvPalette* IlvFilledFloatMatrixItem::getInvertedPalette ( ) const

Returns the palette used to display this matrix item when it is selected.

Returns: The palette used to display this matrix item when it is selected.

See also: getPalette().

◆ getLabel()

virtual const char* IlvFilledFloatMatrixItem::getLabel ( ) const

virtual

Returns the label that identifies this matrix item.

Returns: The label that identifies this matrix item. The returned string must not be deleted or modified.

See also: setLabel().

Reimplemented from IlvFloatMatrixItem.

◆ getPalette()

IlvPalette* IlvFilledFloatMatrixItem::getPalette ( ) const

Returns the palette used to display this matrix item.

Returns: The palette used to display this matrix item.

See also: getInvertedPalette().

◆ minimumSize()

virtual void IlvFilledFloatMatrixItem::minimumSize	(	const IlvMatrix *	matrix,
		IlvDim &	width,
		IlvDim &	height
	)		const

virtual

Returns the preferred size of the item.

The preferred size is the size that the item must have for its content to be entirely visible. Uses width and height to return the preferred size of this item when stored in matrix. This method is called by the member functions IlvMatrix::getColumnFittingSize and IlvMatrix::getRowFittingSize.

Parameters

matrix	The matrix to which the item belongs.
width	The returned preferred width of the item.
height	The returned preferred height of the item.

See also: IlvMatrix::getColumnFittingSize(), IlvMatrix::getRowFittingSize().

Reimplemented from IlvAbstractMatrixItem.

◆ setBackground()

virtual void IlvFilledFloatMatrixItem::setBackground ( IlvColor * color )

virtual

Sets the background color of this matrix item.

The default implementation does nothing.

Parameters

color The new background color.

See also: setPalette(), setForeground(), setFont(), IlvFilledLabelMatrixItem, IlvFilledIntMatrixItem, IlvFilledFloatMatrixItem, IlvFilledDoubleMatrixItem.

Reimplemented from IlvAbstractMatrixItem.

◆ setFont()

virtual void IlvFilledFloatMatrixItem::setFont ( IlvFont * font )

virtual

Sets the font of this matrix item.

The default implementation does nothing.

Parameters

font	The new font.

See also: setPalette(), setForeground(), setBackground(), IlvFilledLabelMatrixItem, IlvFilledIntMatrixItem, IlvFilledFloatMatrixItem, IlvFilledDoubleMatrixItem.

Reimplemented from IlvAbstractMatrixItem.

◆ setForeground()

virtual void IlvFilledFloatMatrixItem::setForeground ( IlvColor * color )

virtual

Sets the foreground color of this matrix item.

The default implementation does nothing.

Parameters

color The new foreground color.

See also: setPalette(), setBackground(), setFont(), IlvFilledLabelMatrixItem, IlvFilledIntMatrixItem, IlvFilledFloatMatrixItem, IlvFilledDoubleMatrixItem.

Reimplemented from IlvAbstractMatrixItem.

◆ setLabel()

virtual void IlvFilledFloatMatrixItem::setLabel	(	const char *	label,
		IlBoolean	copy = `IlTrue`
	)

virtual

Sets the label of the matrix item.

Parameters

label	The label of the matrix item.
copy	Specifies whether a label should be copied. If the value is `IlFalse`, then you must allocate some memory for the label because in any case the label characters are deleted from the memory by the `IlvAbstractMatrixItem`.

See also: getLabel().

Reimplemented from IlvFloatMatrixItem.

◆ setPalette()

virtual void IlvFilledFloatMatrixItem::setPalette ( IlvPalette * palette )

virtual

Sets the palette of this matrix item.

The default implementation does nothing.

Parameters

palette The new palette.

See also: setBackground(), setForeground(), setFont(), IlvFilledLabelMatrixItem, IlvFilledIntMatrixItem, IlvFilledFloatMatrixItem, IlvFilledDoubleMatrixItem.

Reimplemented from IlvAbstractMatrixItem.

◆ write()

virtual void IlvFilledFloatMatrixItem::write ( IlvOutputFile & file ) const

virtual

Writes an object description to a file.

Writes out, in a file, the object description. This description contains all the information necessary to create an exact copy of this object by means of the member function readItem().

Parameters

file	The name of the file to be written to.
