Description Stephan Mann CLA 2010-07-20 04:36:25 EDT 
For some reason, a ColumnFormatter that returns an image in any other than the first column results in an empty space in the first column, exactly as wide as the image in the other column. Additionally, if a ColumnFormatter is set to the first column, the properties of that image seem to "leak" to any other ColumnFormatter that is used in this table.

I've attached screenshots and a snippet to reproduce this behavior. Let me know if you need anything else.

Thanks, I will investigate this approx. next week.

> a ColumnFormatter that returns an image in any other than the first column results in an empty space in the first column

By the way -- if my memory does not fail me: 1st issue should be a known SWT bug.
Comment 6 Elias Volanakis CLA 2010-07-26 17:25:08 EDT 
Potentially, it could turn out that the images MUST have the same size or even only 16x16 -- I'll investigate what SWT supports.
Comment 7 Elias Volanakis CLA 2010-07-26 17:25:55 EDT 
You can also try it yourselft by using Table and TableItem only (no ridget / viewer / labelprovider).
Comment 8 Stephan Mann CLA 2010-08-17 03:51:54 EDT 
As expected, you're right. This is a known Windows "bug". There is a workaround for Windows but this would require to write OS specific code. So I guess we have to live with it.

Since Christian marked this bug as blocked by bug43910 I'm attaching my SWT only snippet to reproduce this behavior. This bug was observed under Windows 7 using SWT 3.6.0 and JDK 1.6.0 update 20.
