Thank you for the response. I think I haven't been as clear as can bee in my previous mail.
I'd like to do this "from Octave" (as a script or in the Octave's command shell): 0. % this is a Octave script: 1. gtk_imshow (x, r,c); 2. pause 3. gtk_imshow (x.*2, r,c); 4. pause 5. gtk_imshow (a_beautiful_filter(x), r,c); Where x is a r x c matrix. r,c = # of rows and columns. gtk_imshow will call Gtk+ application to show the x image. Now I can call a Gtk+ application from Octave but I'd like the Gtk+ application to: - Not to die when the image is shown. - Be able to represent another image in the same created window. - Die with another command from Octave ... Note: - One time the user has called gtk_imshow from Octave's command shell, the control returns to the Octave's prompt (how can I do this?) - The present Octaves's imshow implementation do this: I think the question is more clear now. If not let me know please. I'm very interesting in do this little application.
