NAME
       _Xm* - LessTif Internal Functions

DESCRIPTION
       When the	LessTif	project	began some discussion was undertaken about the
       use of the previously undocumented internal _Xm..  functions  in	 Motif
       1.2.  Apparently	many of	those functions	have been transformed to Xme..
       functions in OSF/Motif(R) 2.x and are also documented.  As many	people
       use  these  functions in	their code (especially widget writers) the im-
       plementation of	the  _Xm..  functions  is  important  to  the  LessTif
       project.

       Below is	a (outdated!) list of functions	currently taken	from the Less-
       Tif header files.

CONVENIENCE FUNCTIONS
       void _XmCalcLabelDimensions(Widget w);

       Sets the	core width and height values to	the values needed  to  display
       the  current  label  contents.  It takes	into account the label type as
       well as all of the margin resources.

       Boolean _XmGetInDragMode(Widget w);

       returns True, if	the widget (e.g. push button,...)  resides in  a  menu
       and the user is currently dragging the mouse with button	1 pressed over
       the menu	items.	This way a widget can figure out, whether it must  re-
       draw  itself in the armed state if the widget gets a PrimitiveEnter ac-
       tion.

       Boolean _XmIsEventUnique(XEvent *event);

       Unknown Function

       Widget _XmGetRC_PopupPosted(Widget w);

       Returns the widget id of	the parent  of	the  menu  that	 is  currently
       posted by any of	the children of	w.  In other words the id of the shell
       that is cascaded	from menu w.

       void _XmRecordEvent(XEvent *event);

       Unknown Function

       void _XmSetInDragMode(Widget w, Boolean flag);

       this is used to enter or	leave the dragging mode	within the  menu  sys-
       tem.

       XmFontListEntry	 _XmFontListEntryFromTag(XmFontList   fontlist,	  char
       *tag);

       Unknown Function

       void _XmConfigureObject(Widget g, Position  x,  Position	 y,  Dimension
       width, Dimension	height,	Dimension border_width);

       _XmConfigureObject is a wrapper around XtConfigureWidget(3) which insu-
       lates a widget writer from the burden of	checking whether an object  is
       a  widget  or  a	gadget.	 The way for a manager widget (any subclass of
       XmManager; they're supposed to do geometry management for  their	 chil-
       dren)  to  set  the  layout of a	child is to use	this function.	In the
       case of a widget, XtConfigureWidget is called.  For a gadget, the geom-
       etry fields are manipulated directly.

       Unknown Function

       int _XmMicroSleep(long secs);

       Unknown Function

       void _XmInternAtomAndName(Display *display, Atom	atom, String name);

       Associates  an  atom  name with an atom id (and vice versa) without the
       need to query the X server first	for the	atom id.  This way any name to
       id  mapping  (as	 well as the id	to name	mapping) can be	set on a given
       display.

       void  _XmVirtualToActualKeysym(Display  *Dsp,   KeySym	VirtualKeysym,
       KeySym *RealKeysymReturn, Modifiers *ModifierReturn);

       For  the	 given	virtual	 keysym	 (which	must be	one of the = osfXK_xxx
       keysyms)	returns	the real keysym	as well	as the modifiers which make up
       that  particular	 virtual  keysym.   If	asked  for  an invalid virtual
       keysym, _XmVirtualToActualKeysym	returns	NoSymbol for the real keysym.

       int _XmVirtKeysLoadFallbackBindings(Display *Dsp, String	*Bindings);

       Installs	the default key	bindings for a specific	display.  If  th=  ere
       are any vendor specific default bindings	available, then	the appropiate
       one= will be installed instead of the fallback key bindings.  Addition-
       ally,  the  bindings  installed are returned in Bindings. The caller is
       responsible for freeing the space occupied by this key binding descrip-
       tion  string. The return	code seems to be always	zero. At least LessTif
       will always retur= n a zero...

       Boolean _XmVirtKeysLoadFileBindings(String filename,  String  *binding=
       );

       Reads  in  a file containing a description of the virtual key bindings.
       If succesful, returns True and the description string. The  caller=  is
       responsible for freeing the memory lateron.

       void _XmVirtKeysInitialize(Widget w);

       Sets  up	 the  virtual key bindings for a display. The widget specified
       must be a XmDisplay widget, otherwise _XmVirtKeysInitialize  will  deny
       the  attempt to set up the key bindings.	The function first checks sev-
       eral places in order to catch up	key binding description. If all	fails,
       it will install fallback	key bindings. This internal function is	called
       during when initializing	a XmDisplay widget.

       void _XmVirtKeysDestroy(Widget w);

       Cleanup any leftovers from the virtual binding mechanism	when  destroy-
       ing a XmDisplay widget.

       void  _XmVirtKeysHandler(Widget w, XtPointer Data, XEvent *Event, Bool-
       ean *ContDispatch);

       This handler is installed on every widget. It just records the  current
       key press event in an widget instance field private to a	XmDisplay wid-
       get.
