Class BaseTileBoard

  • All Implemented Interfaces:
    IColorPicker, org.eclipse.swt.graphics.Drawable
    Direct Known Subclasses:
    CustomTileBoardWidget, PredefinedTileBoardWidget
    public class BaseTileBoard
extends org.eclipse.swt.widgets.Canvas
implements IColorPicker
    This is a base class for a concrete tile board. It renders the provided array of colors as a board filled with color tiles. It deals mouse selection events and keyboard navigation events. The widget informs its clients with ColorChangedEvent on color selection. Alternatively, one can use JFace data binding. Then, perhaps ColorObservables#observeColorWidget(IColorPicker) will be useful.
