ProgressbarGadget not updating

[Joestes]

At the begin of my application I load quite a lot of data. I'm showing a Progressbargadget to show the progress. The problem is that it doen't update in steps, I only see it's being filled at the end, when all data is loaded... Is there a wait to update it during the process?

Thanks!
