disposing widgets in a tableviewer [message #643601]

Hello,

I have a tableviewer that can be refreshed and the structure (n. rows/columns) changes each time. The table contains only swt images generated using GC from a ModelProvider.

Even though I dispose the GC images in the ModelProvider, after a number of refreshes the table won't display more images (3 dots instead) and no error message is printed on the console.

What else should I dispose? (i am not getting any no more handles message)

Thanks!

Actually I found that I was not disposing the images...looks like it works now.

This is probably to much hand-waving, we need to see more code to help
here. Without any further information I assume that you forgot to
dispose the images after each new creation. It can also be a refresh
problem - Where does the drawing happen?
