Is my terminal an X-device from IDL? [message #1648] Tue, 04 January 1994 08:18

Is there any way (other than waiting for the error message on trying to open a window or a widget) to tell from within IDL whether the user is using an X-terminal or workstation.

The particular problem I have in mind is a piece of software which can be run either from widgets or via a command line interface, with the widget interface to start up if possible. This works nicely by using the !D.FLAGS to check if widgets are available for the current device, but I haven't been able to find a way (suitable for unsophisticated users) to check whether the X-device can be opened.
