Hi,
how can i hide the selection (not the row or cell) in a table ?
Deselect() doesnt work as expected, my example should result in showing
no selection at all.
(I want to hide the selection made by swt and code my own that simply
colors the clicked cells.)

Thanks in advance,
Yves

I have figured out the bug:
replace
table.addListener (SWT.Selection, new Listener () {
with
table.addListener (SWT.MouseDown, new Listener () {
