Hi, I'm not a very experienced programmer but just giving the Gtk-server, BASH, Glade combination a try. The GUI I made in Glade has a calendar widget and I can retrieve it's widget ID and access it's day_clicked event: # Get calendar widget ID and connect signal gtk "gtk_server_glade_widget calendar1" calendar1_ID=$RESULT gtk "gtk_server_connect $calendar1_ID day-selected calendar_clicked" But when I try to use get_date I am getting "-1" returned: # Initialize EVENT variable EVENT=0 # Mainloop while [[ $EVENT != "main_window" && $EVENT != "button_exit" ]] do gtk "gtk_server_callback WAIT" EVENT=$RESULT if [[ $EVENT = "calendar_clicked" ]] then gtk "gtk_calendar_get_date $calendar1_ID" text="'$RESULT'" echo $text # this is printing "-1" on console fi done It may be that I need to process the $RESULT more as the GTK docs say it returns a tuplet of three integers for year month day, but may BASH knowlege is also limited at this stage, or is it because the calendar widget needs to be setup in the gtk-server.cfg to be usable. Anyone else have experience with this widget? Regards Bill
