NAME
LessTif Internal Functions
DESCRIPTION
When the LessTif project began some discussion was under-
taken about the use of the previously undocumented internal
_Xm.. functions in Motif 1.2. Apparently these functions
have been transformed to Xme.. functions in OSF/MotifO 2.0
and are also documented. As many people use these functions
in their code (especially widget writers) the implementation
of the _Xm.. functions is important to the LessTif project.
Below is a list of functions currently taken from the
LessTif 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 redraw itself in the armed state
if the widget gets a PrimitiveEnter action.
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 system.

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 insulates 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 children) 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
geometry fields are manipulated directly.

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 Virtu-
alKeysym, 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, _XmVirtualToActu-
alKeysym 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. Additionally, the bindings installed
are returned in Bindings. The caller is responsible for
freeing the space occupied by this key binding description
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 _XmVirtKey-
sInitialize will deny the attempt to set up the key bind-
ings. The function first checks several 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 destroying a XmDisplay widget.
void _XmVirtKeysHandler(Widget w, XtPointer Data, XEvent
*Event, Boolean *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 widget.
