Mouse event queue flushing/blocking window movement ?

[frank zeppenfeldt]

We are trying to build a robust user interface for some real time
applications and have some questions about SunView.

1. Is it possible to flush the event queue from the mouse to avoid
   buffering of button presses etc? I tried with the CONSUME-mask disabling
   and enabling but this does not work for canvases. In these you always have
   to CONSUME the basis mouse events.

2. Is it possible to disable the moving of windows if you press the middle
   mouse button  ?

3. It seems that if you are moving windows, the other processes do nothing
   anymore. Is this related to the priority of SunView ? We tried running
   SunView at a higher/lower priority but it does not make any difference.

4. Would things like tailoring your user interface exactly to your needs
   become easier if we switch to OpenWindows ?

5. Does anyone have some experience in building very robust interfaces ,
   in a real-time environment ( using X or SunView ) ?

Thanks in advance for any help or comments, Frank.
