OwnerDrawLabelProvider ignores setting event.height [message #727637]

I'm currently trying to increase our table row heights by setting a larger value to event.height in OwnerDrawLabelProvider.measure (Windows XP and Windows 7, SWT/JFace 3.7.0). Unfortunately, no matter what value I set, the table row height remains the same. I've debugged a little bit and found out, that in Table.sendMeasureItemEvent always setItemHeight is invoked with the designed height, so for some magic reason Windows (?) ignores it. Does anybody has a (vague) idea what could be the reason?

Did you looked at
http://dev.eclipse.org/viewcvs/viewvc.cgi/org.eclipse.jface.snippets/Eclipse%20JFace%20Snippets/org/eclipse/jface/snippets/viewers/Snippet010OwnerDraw.java?view=markup
which controls the height of a table-rows.

My current wild guess is that you miss a line like this:

OwnerDrawLabelProvider.setUpOwnerDraw(viewer);

I've tried this sample yesterday and it worked fine, even when uncommenting the deprecated OwnerDrawLabelProvider.setUpOwnerDraw(viewer);

Ownerdraw works fine in our project, too. Only the event.height is ignored, event.width is respected.
