TChain::Draw, ProgressBar and gSystem->ProcessEvents()

Hi all,

is it possible (like in TTreeViewer) to get a TGProgressBar setup when doing TChain::Draw (btw: in TTreeViewer it shows the progress 'per-file'). Is it possible - in a precompiled program - that TChain::Draw somehow calls gSystem->ProcessEvents() (regularily, eg 25 times a second) so that a GUI doesn't stop to respond...
