XmtHelpIn...ontextHelp(3)  Library Functions Manual  XmtHelpIn...ontextHelp(3)

NAME
       XmtHelpInstallContextHelp(),  XmtHelpContextHelpCallback()  -  keyboard
       bindings	for context help.

SYNOPSIS
       #include	<Xmt/Help.h>

       void XmtHelpInstallContextHelp(Widget root, XtCallbackProc proc,
		      XtPointer	data)

       void XmtHelpContextHelpCallback(Widget w, XtPointer unused1, XtPointer
		      unused2)

ARGUMENTS
       INPUTS

       root   The root of the widget tree for which the	specified context help
	      callback is to be	registered.

       proc   The callback procedure to	register.

       data   The data to register with	the callback procedure.

       w      For XmtHelpContextHelpCallback(),	the widget for	which  context
	      help is to be displayed.

       unused1,	unused2
	      These arguments to XmtHelpContextHelpCallback() are unused.

DESCRIPTION
       XmtHelpInstallContextHelp()   recursively  traverses  the  widget  tree
       rooted at root and registers the	callback procedure  proc  with	client
       data  data on the XmNhelpCallback callback list of every	widget that is
       a Motif widget or a subclass and	that has its  XmNtraversalOn  resource
       set  to True. That is, it calls XtAddCallback() for the XmNhelpCallback
       for every wid get that can have the keyboard focus. All	Motif  widgets
       and  their  Xmt	subclasses  have an XmNhelpCallback callback list, and
       invoke the procedures registered	on that	list whenever  they  have  the
       keyboard	focus and the user strikes the Help key	(usually bound to F1).

       XmtHelpContextHelpCallback()  is	 a  convenience	 function  that	 calls
       XmtHelpDisplayContextHelp() to display context help on  the  widget  w.
       This  function  is of type XtCallbackProc, so it	can be directly	regis-
       tered on	the XmNhelpCallback callback list supported by all  Motif  and
       Xmt  widgets.  It  can also be passed to	XmtHelpInstallContextHelp() to
       register	it on many widgets at once.
