I see that bug 106472 = 106730 reporting post-drag cheese on a Sash with
SWT.HORIZONTAL is closed, and indeed all the Sashes I can find (in my
RCP or in Eclipse its own self) that are SWT.HORIZONTAL seem to behave
correctly. (Is Bug 28530 also about SWT.HORIZONTAL?)
However, I am unable to find an example of a Sash with SWT.VERTICAL in
Eclipse its own self, and my Sash with SWT.VERTICAL definitely cheeses
up (see attachment). [Nothing much special about what I have in the two
Sashes: GridLayout, two CheckBox-Table/Tree's above, and one Table
below, which has an OwnerDrawLabelProvider; the whole thing is created
using FormToolkit.]
New bug? (I tried a small amount of static analysis of
SashForm.onDragSash() and did not *see* a problem ...)
