Dear Rooters In TCanvas "option" menu, if "Event Status" is selected, coordinate information can be shown at the bottom of the Canvas. It's something like the following exmple: Pad example TFrame 122,333, x=1.97,y=3.06 In above example, "x" and "y" give the position of your mouse in a TFrame that contains the histogram. Could you tell me how to get the value of "x" and "y" in my code. I did not manage to find answer in the source code of TCanvas. Sincerely yours Xie
