Hi, I'm developing a histogram browser for MINOS online monitoring system, using Qt ROOT layer - btw I think it's great that it has been included in the standard ROOT distribution. It has been very helpful (at least for me) I've used Qt designer to create gui main app window with two ROOT canvases embedded as TQtWidgets - a screenshot of how the browser looks is in http://www.slac.stanford.edu/~avva/OmHistory.png The question I have - I can't figure out how to process mouse clicks in TQtWidget embedded ROOT canvases - I'd like to make it possible to select a certain histogram bin by clicking on it. Is there any example/tutorial around that shows how to do it? Thanks, Sergei Avvakumov
