[news.eclipse.platform.swt] Re: how to underline tree item when mouse ho

[Tom Schindl <tom.schindl@xxxxxxxxxxxxxxx>]

You'll need to switch the tree to owner draw mode (which means you'll 
need to draw the content of the cell your own). Afterwards install a 
mouse-move listener on the tree, check with TreeItem-cell-index you are 
hovering (TreeItem#getBounds(int)) and trigger a redraw of the hovered 
cell (the same is true of course also when you leave the cell you need 
to redraw without underline).
