[comp.windows.x] Programatically Dispensing with MWM Decorations

ries@venice.SEDD.TRW.COM (Marc Ries) (12/22/89)

[In response to my plea for help, the following code was emailed to
me.  Unfortunately, my mailer doesn't recognize the senders email
address so I could not respond directly. I have left out the orig.
senders name.  Thanks to the sender for at least responding 8-)]

The problem is, the code doesn't work, at least on our HP 360's
running HP MOTIF under HPUX 7.0.  I ran the following code, and
on our system, I still got a pushbutton widget with a full set of
MWM decorations around it?!?!?  

Is it HP MOTIF or me or ????

================================================================
/* mwm3.c - change mwm borders and frames. Based on pushb.c */
#include <stdio.h>
#include <X11/Intrinsic.h>
#include <X11/Shell.h>
#include <X11/AtomMgr.h>
#include <X11/Protocols.h>
#include <X11/MwmUtil.h>
#include <Xm/Xm.h>
#include <Xm/PushB.h>

void Exit (widget, closure, call_data)
Widget widget;
caddr_t closure, call_data;
{
printf ("About to Exit\n");
exit();
}

main (argc, argv)
int argc;
char *argv[];
{
Widget toplevel, pushb;
Arg arglist[10];
int n;

toplevel = XtInitialize(argv[0], "Motif", NULL, 0, &argc, argv);

pushb = XmCreatePushButton (toplevel, "Close", NULL,0);
XtManageChild (pushb);
XtAddCallback (pushb, XmNactivateCallback, Exit, NULL);
XtRealizeWidget (toplevel);

  {
  Display *display = XtDisplay (toplevel);
  Atom Motif_atom = XmInternAtom (display, _XA_MWM_HINTS, False);
  PropMwmHints data;

  data.flags = MWM_HINTS_DECORATIONS;
  /* leave out resize handles, title, system menu, zoom */
  data.decorations = MWM_DECOR_BORDER | MWM_DECOR_TITLE 
				| MWM_DECOR_MINIMIZE;

  /* property will stay there, present for when Mwm finally runs */
  XChangeProperty (display, XtWindow(toplevel), Motif_atom,
	Motif_atom, 32, PropModeReplace, (unsigned char *) &data, 
	PROP_MOTIF_WM_HINTS_ELEMENTS); 
  }

XtMainLoop();
}
================================================================


    Am I missing something or is HP Motif screwed up?  In either case,
    I typed in the above code verbatim and ran it and none of the
    border attributes changed (ie, I still had a push-button widget
    appear with a full MWM border decorations).

    Thanks,

    Marc Ries (ries@venice)
