	To assign a signal handler (a callback} first click on the object for which you want to assign a handler. Look on the left side of the screen. There will be a properties inspector window. This allows you to change the various attributes of the window primitive. The next tab is the signal handlers tab. from this tab, double-click on the event you want to attach ~~code~~ to.

			For GalaxSee, I have written a simple python client/server architecture. The qt interface makes a system call that launches the python client that sends a Galaxsee job to the server where the mpiexec call is executed.

			It looks like this might not be necessary, as Matt is implementing a Galaxsee server that listens for job requests on a tcp port. When this materializes, the server functionality, ie parsing the command and running the appropriate application with the right parameters can be moved to the python client running on the touchscreen host.

I have successfully built a qt interface for GalaxSee using qt designer. the current versions are located in svn. When the binary is executed, the window fits perfectly on the touchscreen display at 64O x 48O resolution.
