Method Detail

paintCell

void paintCell(ILayerCell cell,
               org.eclipse.swt.graphics.GC gc,
               org.eclipse.swt.graphics.Rectangle bounds,
               IConfigRegistry configRegistry)

getPreferredWidth

int getPreferredWidth(ILayerCell cell,
                      org.eclipse.swt.graphics.GC gc,
                      IConfigRegistry configRegistry)

Get the preferred width of the cell when rendered by this painter. Used for auto-resize.

Parameters:

cell - The cell for which the preferred width is requested.

gc - The GC that is used for rendering.

configRegistry - The IConfigRegistry that contains the configuration used for rendering.

Returns:

The preferred width of the given cell when rendered by this painter.

getPreferredHeight

int getPreferredHeight(ILayerCell cell,
                       org.eclipse.swt.graphics.GC gc,
                       IConfigRegistry configRegistry)

Get the preferred height of the cell when rendered by this painter. Used for auto-resize.

Parameters:

cell - The cell for which the preferred height is requested.

gc - The GC that is used for rendering.

configRegistry - The IConfigRegistry that contains the configuration used for rendering.

Returns:

The preferred height of the given cell when rendered by this painter.

getCellPainterAt

ICellPainter getCellPainterAt(int x,
                              int y,
                              ILayerCell cell,
