Constructor & Destructor Documentation

IlvFilledIntMatrixItem::IlvFilledIntMatrixItem	(	IlvPalette *	palette,
		IlInt	value
	)

Constructor.

Initializes a new instance of the class IlvFilledIntMatrixItem.

Parameters:

	palette	The matrix item palette.
	value	The integer value encapsulated by the item.

IlvFilledIntMatrixItem::IlvFilledIntMatrixItem	(	IlvMatrix *	matrix,
		IlInt	value
	)

Constructor.

Initializes a new instance of the class IlvFilledIntMatrixItem.

Parameters:

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

IlvFilledIntMatrixItem::IlvFilledIntMatrixItem	(	IlInt	value,
		IlvPalette *	palette,
		IlvPalette *	invpal
	)

Constructor.

Initializes a new instance of the class IlvFilledIntMatrixItem.

Parameters:

	value	The integer value of the item.
	palette	The palette of the item.
	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

virtual IlvAbstractMatrixItem* IlvFilledIntMatrixItem::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 IlvIntMatrixItem.

virtual void IlvFilledIntMatrixItem::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.

IlvAbstractMatrix::drawItem, drawLabel

Reimplemented from IlvAbstractMatrixItem.

IlvPalette* IlvFilledIntMatrixItem::getInvertedPalette

(

)

const

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

Returns:

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

See also:

getPalette

virtual const char* IlvFilledIntMatrixItem::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 IlvIntMatrixItem.

IlvPalette* IlvFilledIntMatrixItem::getPalette

(

)

const

Returns the palette used to display this matrix item.

Returns:

The palette used to display this matrix item.

See also:

getInvertedPalette

virtual void IlvFilledIntMatrixItem::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.

IlvMatrix::getColumnFittingSize, IlvMatrix::getRowFittingSize

Reimplemented from IlvAbstractMatrixItem.

static IlvAbstractMatrixItem* IlvFilledIntMatrixItem::readItem	(	IlvInputFile &	file,
		IlvDisplay *	display
	)			[static]

Reads an object description from a file.

Reads an object description from the file input. It reads the information that was saved by the member function write to be able to create a new instance of this object. Usually, because of the availability of the constructor that expects an IlvInputFile, readItem should be equivalent to :

 IlvAbstractMatrixItem*
 MyClass::readItem(IlvInputFile& file, IlvDisplay* display)
 {
     return new MyClass(file, display);
 }

Parameters:

	file	The file to be read from.
	display	The display used to create the object.

See also:

DeclareMatrixItemInfoRO, DeclareMatrixItemInfo, IlvPredefinedMatrixItemIOMembers.

Warning:

[note] The readItem method is not capitalized like other static methods so that it is consistent with the write method.

Reimplemented from IlvIntMatrixItem.

virtual void IlvFilledIntMatrixItem::setBackground

(

IlvColor *

color

)

[virtual]

Sets the background color of this matrix item.

The default implementation does nothing.

Parameters:

color

The new background color.

Reimplemented from IlvAbstractMatrixItem.

virtual void IlvFilledIntMatrixItem::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.

virtual void IlvFilledIntMatrixItem::setForeground

(

IlvColor *

color

)

[virtual]

Sets the foreground color of this matrix item.

The default implementation does nothing.

Parameters:

color

The new foreground color.

setPalette, setBackground, setFont, IlvFilledLabelMatrixItem, IlvFilledIntMatrixItem, IlvFilledFloatMatrixItem, IlvFilledDoubleMatrixItem

Reimplemented from IlvAbstractMatrixItem.

virtual void IlvFilledIntMatrixItem::setLabel	(	const char *	label,
		IlBoolean	copy = IlTrue
	)			[virtual]

Sets the label of the matrix item.

Parameters:

	label	The label of the matrix item.
	copy	A Boolean value specifying 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.

getLabel

Reimplemented from IlvIntMatrixItem.

virtual void IlvFilledIntMatrixItem::setPalette

(

IlvPalette *

palette

)

[virtual]

Sets the palette of this matrix item.

The default implementation does nothing.

Parameters:

palette

The new palette.

Reimplemented from IlvAbstractMatrixItem.

virtual void IlvFilledIntMatrixItem::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.
