Execuse me but I didn't understand why this
" class LiveObject: public TTimer "
doesn't work for you ?
Could you send me (not to roottalk) the further information to
figure your needs out.
Have a look at the last version of ROOT 2.00/10
It says:
//
// 18/07/1998 19.17.01 by Fons Rademakers

- TSystem: new method ProcessEvents(). Call this method regularly in
tight calculation loops. It allows the processing of GUI, socket and
timer events. Most importantly it allows the clean interruption of
such a tigh loop. That is, it returns kTRUE when the users wants to
terminate the loop. Currently the user can terminate the loop by
selecting the canvas menu View/Interrupt or by hitting any key in
the canvas. The interrupt flag is set via the routine
TROOT::SetInterrupt(). Of course, this method can be called via any
GUI button.
- TROOT: new methods SetInterrupt() and IsInterrupted(). Used to
toggle
the variable TROOT::fInterrupt.
- TRootCanvas: new menu item View/Interrupt (see above).
- hsimple.C: calls gSystem->ProcessEvents() in main loop.
