I am writing a user interface using ROOT which will update a histogram on the reception of some events. Once the user presses a button the program should wait for messages and update the histogram based on the data contains in the message.
I was able to get this working, but during the time the program is waiting for messages, the user interface is not refreshing. (If I move another window on top of the user interface the things get erased including the histograms).
I am using Fedora 7 and ROOT version 5.12/00e.
Could someone please help me to find a solution to this problem?
