Ardhan,

In general, no other care than with any other RT application.
Do you wish the GUI to immediately and smoothly reflect important
states of your control application? In this case, you should
consider that the display only changes, if both the GTK+ application
and the X server react in time. For this purpose, it is sometimes
recommended to set the priority of the X server a little less
than that of the control application. Never assign the highest
priority of the system to the X server, since this may completely
block the server. A priority of < 49, however, is normally safe.
Carsten.
