Dear xperts, Any light you can shed on this topic would be most appreciated. I am writing a toolkit-based application which creates *thousands* of widgets over the lifetime of the program. This client will only create widgets and never do an XtDestroyWidget(). It will simply XtUnmanageChildren() and then re-XtManageChildren(), i.e. it will display only certain groups of widgets at a time. To complicate matters, I need approximately 12 instances of this program to run simultaneously. One quickly realizes the need and advantages of using a shared memory architecture for this kind of application. What I am trying to do is pre-allocate (create) all the needed widgets in the shared memory segment, then, have each instance of the program attach to that segment and instantiate by Managing and Realizing its own "copy" of the widgets. Has anyone written or have examples of using widgets under any shared memory scheme? I've tried writing some short programs without success. Any help will be useful. Thanks, "WOOOSH! If they only knew what I was up to." Basil Hashem hashem@mars.jpl.nasa.gov Jet Propulsion Laboratory La Canada Flintridge, CA

I can't imagine how you could use shared memory segments with either Xhp or Motif widgets. Can't you just have one application thread with up to 12 connections? --- Ben
