Wcl users,


A question to you Wcl users.  I would like to read multiple
resource files while in one application loop.  Considering my
first run through the code would look like this:
____________________________________________________________


    /*  -- Initialize Toolkit creating the application shell */
    topShell = XtInitialize (appName, appClass, /* app name and class              */
                             NULL, 0,           /* description of cmd line options */
                             &argc, argv);

    app_context = XtWidgetToApplicationContext (topShell);

    /*  -- Register all application specific callbacks and widget classes */
    RegisterApplicationCallbacks (app_context);

    /*  -- Register all Motif classes and constructors */
    XmpRegisterAll ( app_context );

    /*  -- Create widget tree below toplevel shell using Xrm database */
    WcWidgetCreation (topShell);

    /*  -- Realize the widget tree and enter the main application loop */
    XtRealizeWidget (topShell);

    /*  -- Enter my own main application loop */
    Main_Loop_ACT (display, app_context);



______________________________________________________________________

How do I go about reading in other resource file while the current
display is up at running?  I've tried this, but maybe I'm just grasping
at potential problems, any help?
______________________________________________________________________


    /*  -- Create the Application Shell */

    appShell = XtAppCreateShell(appName, appClass,
                                applicationShellWidgetClass, 
                                display, 
                                NULL, 0);

    resfile = (char *) malloc (strlen(window_file) + 1);
    strcpy (resfile, window_file);
    WcLoadResourceFileCB (appShell, resfile, NULL);

    /*  -- Create widget tree below toplevel shell using Xrm database */
    WcWidgetCreation (appShell);

    /*  -- Realize the widget tree and enter the main application loop */
    XtRealizeWidget (appShell);



________________________________

I'm getting the following error:
________________________________


Warning; WcWidgetCreation (xxxxxx) - Failed
             Problem: No children defined in Xrm database.
             Possible: resource file not found (XENIRONEMENT not set?),
             Possible: top level widget in resource file not name xxxxxx

Error: Shell widget xxxxxx has zero width and/or height


___________________________________________________

What do I need to include in the callback source ?
Let's assume I want a new window when I click on
a pushbutton.  How about this?
____________________________________________________


    /* -- open display, build Xrdb, add to app context */
    dpy = XtOpenDisplay(app, clean, appName, appClass, NULL, 0, &largc, largv );





               THANKS FOR ANY HELP*$&(@#&$(@$^
