Method Details

paintLayer

public void paintLayer(ILayer natLayer,
 org.eclipse.swt.graphics.GC gc,
 int xOffset,
 int yOffset,
 org.eclipse.swt.graphics.Rectangle rectangle,
 IConfigRegistry configuration)

Specified by:

paintLayer in interface ILayerPainter

Parameters:

natLayer - The layer to paint.

gc - GC used for painting

xOffset - x offset of the layer from the origin of the table

yOffset - y offset of the layer from the origin of the table

rectangle - area the layer can paint in

configuration - IConfigRegistry in use by NatTable. Useful for looking up associated painters.

processLayerPainterInformation

protected void processLayerPainterInformation(ILayerPainter painter)

Process the information stored in a ILayerPainter of a composite region. Needed to avoid that the information is lost if the same painter is used in all regions, e.g. the FillHandleLayerPainter.

Parameters:

painter - The ILayerPainter of a composite region.

adjustCellBounds

public org.eclipse.swt.graphics.Rectangle adjustCellBounds(int columnPosition,
 int rowPosition,
 org.eclipse.swt.graphics.Rectangle cellBounds)

Description copied from interface: ILayerPainter

This method is used to adjust the cell bounds when painting the layer. This is most often used to reduce the size of the cell to accommodate grid lines.

Specified by:

adjustCellBounds in interface ILayerPainter

Parameters:

columnPosition - The column position.

rowPosition - The row position.

cellBounds - The actual cell bounds.

Returns:

The adjusted cell bounds.
