Interface ILayerPainter

All Known Implementing Classes:

CellLayerPainter, CompositeLayer.CompositeLayerPainter, GridLineCellLayerPainter, NatGridLayerPainter, NatLayerPainter, SelectionLayerPainter

public interface ILayerPainter

Classes implementing this interface are responsible for painting to the relevant Device. Every layer has a layer painter. A layer can contribute to painting by providing its own painter.

Method Detail

paintLayer

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

Parameters:

natLayer -

gc - GC used for painting

xOffset - of the layer from the origin of the table

yOffset - of the layer from the origin of the table

rectangle - area the layer can paint in

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

adjustCellBounds

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

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.
