Detailed Description

Matrix item class.

Library: ilvadvgdt

Use this class to define a matrix item as a bitmap.

See Also
IlvBitmap, IlvMatrix.

Constructor & Destructor Documentation

IlvBitmapMatrixItem::IlvBitmapMatrixItem ( IlvBitmap bitmap,
IlBoolean  transparent = IlFalse,
IlvPalette palette = 0 
)

Constructor.

Initializes a new instance of the class IlvBitmapMatrixItem.

Parameters
bitmapThe bitmap displayed by the matrix item. This bitmap is locked.
transparentSpecifies whether the bitmap should be transparent (IlTrue) or not (IlFalse).
paletteThe palette used to draw the bitmap.

Member Function Documentation

virtual IlvAbstractMatrixItem* IlvBitmapMatrixItem::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.

virtual void IlvBitmapMatrixItem::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.

IlvBitmap* IlvBitmapMatrixItem::getBitmap ( ) const

Returns a pointer to the bitmap displayed by the matrix item.

Returns
A pointer to the bitmap displayed by the matrix item.
See Also
setBitmap(), IlvBitmap.
virtual const char* IlvBitmapMatrixItem::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.

IlBoolean IlvBitmapMatrixItem::isTransparent ( ) const

Indicates whether the bitmap displayed by the matrix item is transparent.

Returns
IlTrue if the bitmap is transparent and IlFalse otherwise.
See Also
setTransparent(), IlvBitmap::setTransparentColorIndex().
virtual void IlvBitmapMatrixItem::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.

virtual void IlvBitmapMatrixItem::setBackground ( IlvColor color)
virtual

Sets the background color of this matrix item.

The default implementation does nothing.

Parameters
colorThe new background color.
See Also
setPalette(), setForeground(), setFont(), IlvFilledLabelMatrixItem, IlvFilledIntMatrixItem, IlvFilledFloatMatrixItem, IlvFilledDoubleMatrixItem.

Reimplemented from IlvAbstractMatrixItem.

virtual void IlvBitmapMatrixItem::setBitmap ( IlvBitmap bitmap)
virtual

Sets the bitmap displayed by this matrix item.

Parameters
bitmapThe bitmap to be displayed by this matrix item. The old bitmap is unlocked, and the new one is locked.
See Also
getBitmap(), IlvBitmap.
virtual void IlvBitmapMatrixItem::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.

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

Sets the label of the matrix item.

Parameters
labelThe label of the matrix item.
copySpecifies 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 IlvAbstractMatrixItem.

virtual void IlvBitmapMatrixItem::setPalette ( IlvPalette palette)
virtual

Sets the palette of this matrix item.

The default implementation does nothing.

Parameters
paletteThe new palette.
See Also
setBackground(), setForeground(), setFont(), IlvFilledLabelMatrixItem, IlvFilledIntMatrixItem, IlvFilledFloatMatrixItem, IlvFilledDoubleMatrixItem.

Reimplemented from IlvAbstractMatrixItem.

void IlvBitmapMatrixItem::setTransparent ( IlBoolean  val)

Specifies whether the bitmap displayed by the matrix item should be transparent.

Parameters
valSpecifies whether the bitmap displayed by this matrix item should be transparent (IlTrue) or not (IlFalse).
See Also
isTransparent(), IlvBitmap::setTransparentColorIndex().
virtual void IlvBitmapMatrixItem::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.
