Hello,
I want to update the progressMonitor (message and work) in the statusbar
during a call to Figure.paintChildren(). I cannot get it to work however.
Nothing is displayed.
Is it possible? Did anyone have any luck doing the same?

Does that imply that all these processes which do use a progressbar on the
statusline are working as background jobs? Or are are they doing
Display.getCurrent().readAndDispatch() at regular intervals? I tried
readAndDispatch in the paintChildren() method, but that results in rather
messy displays...

If your painting is so slow (and there are valid cases I'm sure), you should
be rendering to an Image, and then just painting that Image. Otherwise,
closing a dialog box or context menu will take too long.
You could then create a job that updates the cached image.
