I think the problem is my main thread does not finish and no GUI 
callbacks are run. No pushbutton callbacks are executed. My thread ends 
with infinite cycle - reading zeromq messages.

Please what would be a recommended way to solve such problem? Would 
running the GUI thread and the reading thread side by side with parallel 
package help? The message reading loop thread must have access to the 
GUI handles currently stored in a global struct.

Thanks a lot for help with principles of using the octave UI elements.

Best regards,

Pavel.
