   A closer look at olwm reveals that it is looking at an  _OL_WIN_ATTR window
   property to set the decorations (see pages 70-72 of OLIT Widget Set
   Programmer's Guide).  I was going to set the "menu_type" atom to
   _OL_MENU_LIMITED for all of our popups but I have been working on a bigger
   problem.  None of our option menus work correctly they popup but then pop right
   back down.

I have finally solved this problem for our application.  I had to set the _OL_WA_WIN_TYPE
property to _OL_WT_OTHER (which tells the window manager not to add anything) then
add the decorations myself.  The following code pieces are from my application:


#include <X11/Xatom.h>
#include <X11/Protocols.h>
#include <Xol/OlClients.h>  
OLWinAttr   *wmWinAttr;
Atom    wmWinAttrAtom;
Atom    wmWtCmd;
Atom    wmWtOther;
long    wmMenuLimited;
Atom    wmDecorAdd;
Atom    wmDecorResize;
Atom    wmDecorHeader;
Atom	wmProtocols;

  ..../* toplevel has been created and 
	display has been opened successfully */

  wmProtocols = XInternAtom(display, "WM_PROTOCOLS", True);

  if (wmProtocols == None) {
    wmWinAttr = NULL;
    wmWinAttrAtom = None;
    wmWtOther = None;
    wmWtCmd = None;
    wmMenuLimited = 0;
    wmDecorAdd = None;
    wmDecorResize = None;
    wmDecorHeader = None;
  }
  else {
    wmWinAttrAtom = XInternAtom(display, "_OL_WIN_ATTR", True);
    wmWtOther = XInternAtom(display, "_OL_WT_OTHER", True);
    wmWtCmd = XInternAtom(display, "_OL_WT_CMD", True);
    wmWinAttr = (OLWinAttr *) malloc(sizeof(OLWinAttr));
    wmWinAttr->win_type = wmWtOther;
    wmDecorAdd = XInternAtom(display, "_OL_DECOR_ADD", True);
    wmDecorResize = XInternAtom(display, "_OL_DECOR_RESIZE", True);
    wmDecorHeader = XInternAtom(display, "_OL_DECOR_HEADER", True);
  }


  ..... /* a dialog box "dbx" has been created ... */

  Atom protocols[2];


    if (!XmIsMotifWMRunning(toplevel)) {
      XChangeProperty(display, XtWindow(XtParent(dbx)), wmWinAttrAtom, XA_ATOM, 
		      32, PropModeReplace, (unsigned char *)wmWinAttr, OLWinAttrNum32s);
      protocols[0] = wmDecorResize;
      protocols[1] = wmDecorHeader;
      XChangeProperty(display, XtWindow(XtParent(dbx->widget)), wmDecorAdd,
	              XA_ATOM, 32, PropModeReplace, (unsigned char *) protocols, 2);
    }





This works great for me except the titles are not quite right.  The title is in
the title area of the dialog box, but I have to resize the box (i.e., widen it) 
to see it.

Hope this helps!
