Detailed Description

Matrix item class.

Library: ilvadvgdt

Use this class to define a matrix item as a graphic object.

See Also
IlvGraphic, IlvMatrix.

Constructor & Destructor Documentation

IlvGraphicMatrixItem::IlvGraphicMatrixItem ( IlvGraphic graphic)

Constructor.

Initializes a new instance of the class IlvGraphicMatrixItem.

Parameters
graphicThe graphic object encapsulated by this item.

Member Function Documentation

virtual IlvAbstractMatrixItem* IlvGraphicMatrixItem::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 IlvAbstractMatrixItem.

Reimplemented in IlvGadgetMatrixItem.

virtual void IlvGraphicMatrixItem::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
matrixThe matrix to which the item belongs.
colThe column where the matrix item is located.
rowThe row where the matrix item is located.
dstThe destination drawing port.
bboxThe bounding box of the matrix item.
clipThe clipping area.
See Also
IlvAbstractMatrix::drawItem, drawLabel

Reimplemented from IlvAbstractMatrixItem.

Reimplemented in IlvGadgetMatrixItem.

IlvGraphic* IlvGraphicMatrixItem::getGraphic ( ) const

Returns a pointer to the graphic object stored in this matrix item.

Returns
A pointer to the graphic object stored in this matrix item.
See Also
setGraphic
virtual const char* IlvGraphicMatrixItem::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 IlvAbstractMatrixItem.

Reimplemented in IlvGadgetMatrixItem.

virtual IlBoolean IlvGraphicMatrixItem::handleSelectionDrawing ( ) const
virtual

Indicates whether the selection drawing is handled by the matrix item.

Returns
IlTrue if the selection drawing is handled by the matrix item and not by the matrix to which it belongs. In this case, the member function IlvMatrix::drawSelection is not called. The default implementation returns IlFalse.
See Also
IlvMatrix::drawSelection

Reimplemented from IlvAbstractMatrixItem.

virtual void IlvGraphicMatrixItem::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
matrixThe matrix to which the item belongs.
widthThe returned preferred width of the item.
heightThe returned preferred height of the item.
See Also
IlvMatrix::getColumnFittingSize, IlvMatrix::getRowFittingSize

Reimplemented from IlvAbstractMatrixItem.

Reimplemented in IlvGadgetMatrixItem.

virtual void IlvGraphicMatrixItem::setBackground ( IlvColor color)
virtual

Sets the background color of this matrix item.

The default implementation does nothing.

Parameters
colorThe new background color.

Reimplemented from IlvAbstractMatrixItem.

virtual void IlvGraphicMatrixItem::setFont ( IlvFont font)
virtual

Sets the font of this matrix item.

The default implementation does nothing.

Parameters
fontThe new font.
See Also
setPalette, setForeground, setBackground, IlvFilledLabelMatrixItem, IlvFilledIntMatrixItem, IlvFilledFloatMatrixItem, IlvFilledDoubleMatrixItem

Reimplemented from IlvAbstractMatrixItem.

virtual void IlvGraphicMatrixItem::setForeground ( IlvColor color)
virtual

Sets the foreground color of this matrix item.

The default implementation does nothing.

Parameters
colorThe new foreground color.
See Also
setPalette, setBackground, setFont, IlvFilledLabelMatrixItem, IlvFilledIntMatrixItem, IlvFilledFloatMatrixItem, IlvFilledDoubleMatrixItem

Reimplemented from IlvAbstractMatrixItem.

void IlvGraphicMatrixItem::setGraphic ( IlvGraphic graphic)

Sets the graphic object stored in this matrix item.

The old graphic object that was stored in this matrix item is deleted.

Parameters
graphicThe new graphic object.
See Also
getGraphic
virtual void IlvGraphicMatrixItem::setLabel ( const char *  label,
IlBoolean  copy = IlTrue 
)
virtual

Sets the label of the matrix item.

Parameters
labelThe label of the matrix item.
copyA 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 IlvAbstractMatrixItem.

Reimplemented in IlvGadgetMatrixItem.

virtual void IlvGraphicMatrixItem::setPalette ( IlvPalette palette)
virtual

Sets the palette of this matrix item.

The default implementation does nothing.

Parameters
paletteThe new palette.
See Also

Reimplemented from IlvAbstractMatrixItem.

virtual void IlvGraphicMatrixItem::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
fileThe name of the file to be written to.
