[news.eclipse.newcomer] Re: Table or TableViewerer - cell renderer

[Tom Schindl <tom.schindl@xxxxxxxxxxxxxxx>]

Hi,

Well Table/TableViewer is IMHO not 100% suited to display a lot of 
images because all images have to have the same size besides that what 
you need what you want to do Ownerdraw is not really needed.

If I where you and have to diplay images in Table like fashion I'd look 
at the http://www.eclipse.org/nebula/widgets/gallery/gallery.php it's 
designed for exactly this purpose.

If you still want to use a native table you should take a look at the 
CellLabelProvider-API which can return a background color for a cell (or 
if you are on pre 3.3 IColorProvider/ITableColorProvider).
