Hello,
I have a table. Odd rows are one color even another. The table has 3 columns.
I use a Label,button(push),button(check) as the editors for the respective columns.
After some reading it seems label or text can not inherit the background color or be transparent, the parts thats not text that is. Is there some other way to do this? Or have I been misinformed? In short I'm hoping for somthing like JLabel with setOpaque(false)

Thank You,
Jason

		table.setLayoutData(new Bag().fillBoth().get());

Hi Jason,

Showing these controls transparently isn't possible, but you should be able
to get close to what you want with a couple of changes:
- Is there a reason that you're embedding Label controls in the first
column? I can't think of advantages that these would give over simply
setting the TableItem's image and text. If you switched to do this then you
would get the correct background.
- There isn't a way to make the push button transparent, which is platform
behaviour.
- For the last column you could give the check Button no text and pack it,
and use custom draw to draw the item text at the correct location to the
right of the checkbox. The only part that would not be transparent would be
the checkbox itself. For info about custom drawing of Table/Tree items see
http://www.eclipse.org/articles/article.php?file=Article-Cus tomDrawingTableAndTreeItems/index.html .

Hopefully these changes can get you reasonably close to what want (?).
