Hi All,

When I use ComboViewer composite in my project, I need to add one image for one certain item in the list, then I set related LabelProvider to the ComboViewer like below:
ComboViewer inforViewer = new ComboViewer(diagramCom0, SWT.DROP_DOWN | SWT.BORDER);
inforViewer.setLabelProvider(new MyLabelProvider());
inforViewer.setContentProvider(new ArrayContentProvider());
inforViewer.setInput(inforList);

The related code in class MyLabelProvider please see below:

public Image getImage(Object element) {
//return one image to use
}

But when I did one debug the code, I find the getImage() methond is never called by any client, why?
Am I wrong or this is one bug? or ComboViewer is not supported to do this thing?

Thanks for your time.
Best Regards,
Devin

Looks like only Tables and Trees support decorating with images.

Hi Brian,
Thanks very much for your replay.

I also checked the sorce code of ComboViewer, you are right, for ComboViewer, there is no ability to decorate with images.

Best Regards,
Devin
