问题 I have a TreeViewer used in an eclipse plugin that uses a content provider and a label provider that implements all of ( ITableLabelProvider , IFontProvider , IColorProvider ).

The problem is that TreeViewer does not automatically clear the selection if you click into empty space. Is there any clean way how to achieve this? My current approach would be to simply hook up a MouseListener to the tree with the following mouseDown method:
