LessTif Internal Functions
<A NAME="lbAC">&nbsp;</A>
<H2>DESCRIPTION</H2>

When the LessTif project began some discussion was undertaken
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/Motif&#174; 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.
<P>

Below is a list of functions currently taken from the LessTif header files. 
<A NAME="lbAD">&nbsp;</A>
<H2>CONVENIENCE FUNCTIONS</H2>

<P>

<B>void _XmCalcLabelDimensions(Widget w);</B>

<P>

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.
<P>

<B>Boolean _XmGetInDragMode(Widget w);</B>

<P>

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. 
<P>

<B>Boolean _XmIsEventUnique(XEvent *event);</B>

<P>

Unknown Function 
<P>

<B>Widget _XmGetRC_PopupPosted(Widget w);</B>

<P>

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.
<P>

<B>void _XmRecordEvent(XEvent *event); </B>

<P>

Unknown Function 
<P>

<B>void _XmSetInDragMode(Widget w, Boolean flag);</B>

<P>

Unknown Function 
<P>

<B>void _XmConfigureObject(Widget g, Position x, Position y, Dimension width, Dimension height, Dimension border_width);</B>

<P>

_XmConfigureObject is a wrapper around
<B><A HREF="XtConfigureObject.html">XtConfigureObject</A></B>(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 
<P>

<B>int _XmMicroSleep(long secs);</B>

<P>

Unknown Function 
<P>

<B>void _XmInternAtomAndName(Display *display, Atom atom, String name);</B>

<P>

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. 
<P>

<B>void _XmVirtualToActualKeysym(Display *Dsp, KeySym VirtualKeysym, KeySym *RealKeysymReturn, Modifiers *ModifierReturn);</B>

<P>

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. 
<P>

<B>int _XmVirtKeysLoadFallbackBindings(Display *Dsp, String *Bindings);</B>

<P>

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... 
<P>

<B>Boolean _XmVirtKeysLoadFileBindings(String filename, String *binding= );</B>

<P>

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. 
<P>

<B>void _XmVirtKeysInitialize(Widget w);</B>

<P>

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 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. 
<P>

<B>void _XmVirtKeysDestroy(Widget w);</B>

<P>

Cleanup any leftovers from the virtual binding mechanism when destroying a XmDisplay widget. 
<P>

<B>void _XmVirtKeysHandler(Widget w, XtPointer Data, XEvent *Event, Boolean *ContDispatch);</B>

<P>

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.
