[yurh <yurh 1web necst nec co jp>]

To all:
        Now I have a problem about display.
        envirament: system: Red Hat9.0
                    GTK Version: GTK+-1.2.10
                    Glib Version: glib1.2.10

Following is what I want to do?
One process to show two display(DISPLAY1: 127.0.0.1:1.0 
                                  DISPLAY2: 127.0.0.1:2.0)


How can I do for it?

PS: if I init two different displays for gtk when Gtk init, and every
thread use one of it? can it solute it??
(what variable do defalut display use ?)

wait for your answer.

Best regards to you all!
