This is the GtkAda version of the C testgtk program, demonstrating the use of most of the GtkAda widgets. Many improvements have been made compared to the original C implementation. This is both a test program, a source of examples, and a nice demo of the GtkAda technology. To build it under unix, simply type make after having configured GtkAda. To build it under windows, use the following command: gnatmake -I../lib -Iopengl -Ipixbuf testgtk -largs -llw -lopengl32 -lglu32
