The Contact Display
A contact-display is created by the open-contact-display function. open-contactdisplay has one required
argument: a symbol which acts as the name of your program. Technically, this is
a resource name which is used to access the values of
resources associated with your program. CLUE resource
management is explained later in Section
. Generally
speaking, this program resource name is used to distinguish your program from
other application programs that may also be running. open-contact-display
has several optional keyword arguments (mainly the same ones used by the CLX
open-display function), but the most frequently used is the host, a
string which gives the network name for the X server host to which you are
connecting.
(setf display
(open-contact-display
'blink ; Application name
:host "server-host")) ; Server host name
contact-display objects are really a subclass of the display data
type defined by CLX2.
The CLX function close-display should always be used
to close the server connection when the program terminates.
