I am using root 3.01-06, RedHat 6.2, Linux kernel 2.2.19-6.2.7 This is an elementary question about root GUI's. I want to show data periodically (say, once per 5 seconds), and have the user press "Start" to start the whole thing. Users will also press other buttons, e.g. to change to another page of display, etc. But the data should be updated period- ically and automatically. I have learned how to "ProcessMessage" and to request the "NeedRedraw" which successfully updates data in my GUI, but how to make this automatic ? Is the general idea to start a "TThread" try to make "NeedRedraw" requests there, or to have my thread send messages back to the GUI window ? thanks, Robert ------------------------------------------------------ Robert W.
