Create a Front Panel configuration file /etc/dt/appconfig/types/language/name.fp.
Define the system-wide control in the file.
Use the CONTAINER_NAME and CONTAINER_TYPE fields to specify the container for the control:
CONTROL control_name { CONTAINER_NAME subpanel_name CONTAINER_TYPE SUBPANEL … }
Save the configuration file.
Choose Restart Workspace Manager from the Workspace menu.
For example, the following control defined in a new file /etc/dt/appconfig/types/language/DigitalClock.fp adds the DigitalClock (in the Desktop_Tools application group) to the Personal Applications subpanel for all users.
CONTROL DigitalClockControl { TYPE icon CONTAINER_NAME PersAppsSubpanel CONTAINER_TYPE SUBPANEL ICON Dtdgclk PUSH_ACTION DigitalClock PUSH_RECALL True }
