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
implementation of the _Xm.. functions is important to the LessTif
project.
Below is a (outdated!) 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.
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
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 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.
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 _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.
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.
