Hi,

i've a little troubles with my SWT application. I've a little window where
i'm trying to display images which are dynamic loaded ...
Everything works fine, but only for two times. It means, i do the request to
display a image on canvas, then i do redraw and image is updated. Whenn i do
the same next time it works also, but on next time it doesn't do redraw ?
I've added a PaintListener to do the image drawing ... and so i can see that
whenn i call the redraw() method on third time nothing happens.
I must resize the windows with mouse to update the image (then it calls self
the redraw() method).
I tred everythin what i found on internet but without result ...

Any idea ? Please help ...

Thanks peter_

Hi,

Try to call the update() method, after redraw().

Regards,
Boby
