Bug 178105 [Viewers] Cell highlighting not customizable for users
I just tried to make implement a TableCursor stragety and found that we need maybe some more API. I'm not happy with the setup-methods but currently maybe Boris has an idea.
bundles/org.eclipse.jface/src/org/eclipse/jface/viewers/SWTFocusCellManager.java
private CellNavigationStrategy navigationDelegate;
	private ColumnViewer viewer;
	private ViewerCell focusCell;
	/**
	 * @param viewer
	 * @param focusDrawingDelegate
	 * @param navigationDelegate
	 */
	public SWTFocusCellManager(ColumnViewer viewer,
			FocusCellHighlighter focusDrawingDelegate,
			CellNavigationStrategy navigationDelegate) {
		this.viewer = viewer;
		this.navigationDelegate = navigationDelegate;
		hookListener(viewer);
	}
	private void handleMouseDown(Event event) {
		ViewerCell cell = viewer.getCell(new Point(event.x, event.y));
