3436.0. "Setting the cursor on a 3520" by TOOK::F_MESSINGER () Fri Oct 05 1990 14:12

My application brings up a window and sets the cursor for that window.  When 
the user moves the cursor out of that window the server does the 
following when running on a 3520:

The application works fine on MicroVax 2000s, VaxStation 3100s and every 
other machine I've tried it on.

This is what I'm doing to set the cursor for the window:

   Display		*dpy;
   Font	                cursorfont;
   Cursor		drawcursor;
   XColor      		white = {0, 65535, 65535, 65535,
                       		DoRed | DoGreen | DoBlue};    /* white */
   XColor     		black = {0, 0, 0, 0,
	                        DoRed | DoGreen | DoBlue};    /* black */
   int			name1;


   dpy = pml_console_globals.display;
   name1 = name + 1;

   cursorfont = XLoadFont ( dpy, "decw$CURSOR");
   if (cursorfont != NULL)
   {
       map_info->window_cursor = XCreateGlyphCursor(dpy,
			    cursorfont, cursorfont,
			    name, name1,
			    &black, &white);
       XUnloadFont(dpy, cursorfont);
       XDefineCursor(dpy, 
                     XtWindow(GobeGetWorkWidget(map_info->map_widget)), 
                     map_info->window_cursor);
    }



Any Ideas?

Thanks,
Fred

  What version of VMS are ya runnin' ?  I've been able to change the cursor
without any problems (from both C and Ada).

  Also...how many planes is your 3520 ?

  The configuration that I use is an 8-plane 3520 running VMS V5.3-1 with
48M.

Jim,
Sorry it took so long to reply,  I had to wait for someone to return from a 
week of classes.

The 3520 is an 8 plane machine running VMS 5.3-2

Not good news, huh?

Thanks,
Fred

  Do ya have a small example program ?

  I will forward you an example in Ada and in C that change the cursor.
