A Tree with a MeasureItem listener doesn't support the horizontal scroll wheel event of a 4-way scrolling mouse.

In the Eclipse SDK, this e.g. makes horizontal scrolling via mouse wheel work in the navigator view, but not in the Package Explorer and Project Explorer (bug 201984 comment 9).

Removing the "bits |= OS.TVS_NOHSCROLL;" in Tree#_addListener(..) makes the horizontal scrolling work, but it also creates a second scroll bar.

This bug hasn't had any activity in quite some time. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet.

If you have further information on the current state of the bug, please add it. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant.
