TQtWidget updates only on mouse click

ROOT
1

Hey all,

I am building a root based qt application using the TQtWidget class. Right now I am trying to plot points in real time as data is acquired from another thread in the program. Is there a reason why using TGraph::Set and TGraph::SetPoint do not update the plot until clicked?

Sorry I am kind of new to ROOT… any suggestions would be welcomed about the proper way to relay new data to be plotted in the TGraph.

Thanks,
pavlovsky

Welcome to Root. The first suggestion is to post in the right forum. This one is for working applications.
