[news.eclipse.platform.swt] Re: Skipping Columns, Highlite selected Cell

[te@xxxxxxxxxxxxxx (Thomas Eichstädt-Engelen)]

hmm, that is exactly the Snippet i have used. It makes use of the 
FocusCellOwnerDrawHighlighter which highlites the focused cell only. What 
i'd like to achieve is highlite the row _and_ highlite the focused cell.

however tab-editing does not work. Here is the peace of code which create 
the Editors:
		TreeViewerFocusCellManager focusCellManager = new 
TreeViewerFocusCellManager(treeViewer,new MyCellHighliter(treeViewer));
		ColumnViewerEditorActivationStrategy actSupport = new 
ColumnViewerEditorActivationStrategy(treeViewer) {
			protected boolean 
isEditorActivationEvent(ColumnViewerEditorActivationEvent event) {
				return event.eventType == ColumnViewerEditorActivationEvent.TRAVERSAL
						|| event.eventType == 
ColumnViewerEditorActivationEvent.MOUSE_DOUBLE_CLICK_SELECTION
						|| (event.eventType == ColumnViewerEditorActivationEvent.KEY_PRESSED 
&&
								(event.keyCode >= 48 /*Zahl 0*/ && event.keyCode <= 57 /* Zahl 9*/ 
|| event.keyCode == 44 /*Komma*/))
						|| event.eventType == ColumnViewerEditorActivationEvent.PROGRAMMATIC;
			}
		};
		
		TreeViewerEditor.create(treeViewer, focusCellManager, actSupport,
				ColumnViewerEditor.TABBING_HORIZONTAL
				| ColumnViewerEditor.TABBING_MOVE_TO_ROW_NEIGHBOR
				| ColumnViewerEditor.TABBING_VERTICAL
				| ColumnViewerEditor.KEYBOARD_ACTIVATION);


MyCellHighliter is merely a copy of FocusCellOwnerDrawHighlighter.

Regarding "5" and there is now way to make it work in 3.4 (the dirtier the 
better ;-) )

Thanks,
