Dear ROOTers, I was wondering what would be the best SIGNAL that could be send by QtRoot to say that the current Pad has been changed or something new happened in the current pad (the purpose is to retrieve the informations of the histograms contained in this current Pad). I was thinking of gPad->IsModified()... however, in the QtRoot Version that I have (downloaded from the GSI-Go4 website), there is no signal avalaible from the class TQRootCanvas except Destroy(). Is there any version of QtRoot that are more advanced and would have the feature I'm looking for ? Thanks for your continuous help, it is very much appreciated. Fred (TRIUMF)
