ILayerPainter (Nebula NatTable 2.0.0-SNAPSHOT API)

All Known Implementing Classes:

CellLayerPainter, ColumnGroupHeaderGridLineCellLayerPainter, CompositeFreezeLayerPainter, CompositeLayer.CompositeLayerPainter, CopySelectionLayerPainter, FillHandleLayerPainter, GridLineCellLayerPainter, NatGridLayerPainter, NatLayerPainter, RowGroupHeaderGridLineCellLayerPainter, 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.

```
void paintLayer(ILayer natLayer,
                org.eclipse.swt.graphics.GC gc,
                int xOffset,
                int yOffset,
                org.eclipse.swt.graphics.Rectangle rectangle,
                IConfigRegistry configuration)
```
    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.
  - 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.
    
    Parameters:
    
    columnPosition - The column position.
    
    rowPosition - The row position.
    
    cellBounds - The actual cell bounds.
    
    Returns:
    
    The adjusted cell bounds.
