Hi all,
I want to show an image only in the selected item of a Table.
Attached there are two code snippets.
In RapTest1, when I select the first item the image shows correctly. But
when I select other item that the first, no image shows.
In RapTest2, if I select the second or the third item the image shows
correctly. When I select the first item and then the second item, the
image disappear.
It seems that images are only displayed if the first item of the Table
has the image.
Is this a bug of RWT Table control?
Thanks,
Enrico

Hi Enrico,
I've reproduced it with the RAP Control Demo - Table. If there is no
image set to the first item, the image is not set to the rest. This
appear to be a bug. As a workaround you can set an transparent empty
image (16x16) instead of null when there is no image.
Best,
Ivan

Hi,
This is rather a 'feature' than a bug, since SWT on Windows shows
this behavior.
From a sensible point of view, I also would consider this to be a bug.
But, as RWT implements a subset of SWT, not only in terms of API but
also semantically, it also adheres to its limitations.
Cheers,
Rüdiger

Hi Rüdiger,
I'm not sure it's a 'feature' in SWT.
Running code snippet in SWT 3.3 and 3.4 on Windows, the Table initially
shows no icons. The first time I click on an item the icon appears and
remains, even clicking second and third item.
This is the behavior I expect that, even in RAP.
Regards,
Enrico

Enrico,
you are right, this should work. It was a misunderstanding on my
side. I file this bug:
237740: [Table] Changing image with selection does not work
