The Xmu Library is a collection of miscellaneous (some might say random)
utility functions that have been useful in building various applications
and widgets.  This library is required by the Athena Widgets.

Starting in XFree86 4.1.0, and incorporated into X11R6.7 and later releases,
a subset of the functions that do not rely on the Athena Widgets (libXaw)
or X Toolkit Instrinsics (libXt) are provided in a second library, libXmuu.
    </p><p>
Programs using either of these libraries are encouraged to determine the
correct compiler and linker options via the <strong class="userinput"><code>xmu</code></strong> or

This function converts a string to an integer shape style.  The string
"rectangle" converts to
<span class="symbol">XmuShapeRectangle</span>,
"oval" converts to
<span class="symbol">XmuShapeOval</span>,
"ellipse" converts to
<span class="symbol">XmuShapeEllipse</span>,
and "roundedRectangle" converts to
<span class="symbol">XmuShapeRoundedRectangle</span>.
The case of the string does not matter.  To use this converter,
include the following in your widget's ClassInitialize procedure:

      </p><pre class="programlisting">

The shape is bounded by the outside edges of the rectangular extents of the
widget.  If the shape is a rounded rectangle, corner_width and corner_height
specify the size of the bounding box that the corners are drawn inside of
(see
<a class="link" href="#XmuFillRoundedRectangle"><code class="function">XmuFillRoundedRectangle</code></a>);
otherwise, corner_width and corner_height are ignored.
The origin of the widget within its parent remains unchanged.

This function converts a string to an immediate child widget of the parent
widget passed as an argument.  Note that this converter only works for
child widgets that have already been created; there is no lazy evaluation.
The string is first compared against the
names of the normal and popup children, and if a match is found the
corresponding child is returned.  If no match is found, the string is
compared against the classes of the normal and popup children, and if a
match is found the corresponding child is returned.  The case of the string
is significant.  To use this converter, include the following in your
widget's ClassInitialize procedure:

      </p><pre class="programlisting">
static XtConvertArgRec parentCvtArg[] = {
  {XtBaseOffset, (XtPointer)XtOffset(Widget, core.parent), sizeof(Widget)},

This converter is identical in functionality to
<a class="link" href="#XmuCvtStringToWidget"><code class="function">XmuCvtStringToWidget</code></a>, except
that it is a new-style converter, allowing the specification of a cache type
at the time of registration.
Most widgets will not cache the conversion results, as the application may
dynamically create and destroy widgets, which would cause cached values to
become illegal.  To use this converter, include the following in the widget's
class initialize procedure:

To create all of the appropriate standard colormaps for every visual of
every screen on a given display, use
<code class="function">XmuAllStandardColormaps</code>.
    </p><p>
This function defines and retains as permanent resources all standard
colormaps which are meaningful for the visuals of each screen of the
display.  It returns 0 on failure, non-zero on success.  If the property of
any standard colormap is already defined, this function will redefine it.
    </p><p>
This function is intended to be used by window managers or a special client
at the start of a session.
    </p><p>
The standard colormaps of a screen are defined by properties associated with
the screen's root window.  The property names of standard colormaps are
predefined, and each property name except
<span class="property">RGB_DEFAULT_MAP</span> may describe at
most one colormap.
    </p><p>
The standard colormaps are: <span class="property">RGB_BEST_MAP</span>,
<span class="property">RGB_RED_MAP</span>, <span class="property">RGB_GREEN_MAP</span>,
<span class="property">RGB_BLUE_MAP</span>, <span class="property">RGB_DEFAULT_MAP</span>,
 and <span class="property">RGB_GRAY_MAP</span>.  Therefore a screen may
have at most 6 standard colormap properties defined.
    </p><p>
A standard colormap is associated with a particular visual of the screen.  A
screen may have multiple visuals defined, including visuals of the same
class at different depths.  Note that a visual id might be repeated for more
than one depth, so the visual id and the depth of a visual identify the
visual.  The characteristics of the visual will determine which standard
colormaps are meaningful under that visual, and will determine how the
standard colormap is defined.  Because a standard colormap is associated
with a specific visual, there must be a method of determining which visuals
take precedence in defining standard colormaps.
    </p><p>
The method used here is: for the visual of greatest depth, define all
standard colormaps meaningful to that visual class, according to this order
of (descending) precedence:
<span class="symbol">DirectColor</span>;
<span class="symbol">PseudoColor</span>;
<span class="symbol">TrueColor</span>
and
<span class="symbol">GrayScale</span>;
and finally
<span class="symbol">StaticColor</span>
and
<span class="symbol">StaticGray</span>.
    </p><p>This function allows success, on a per screen basis.  For example, if a map
on screen 1 fails, the maps on screen 0, created earlier, will remain.
However, none on screen 1 will remain.  If a map on screen 0 fails, none
will remain.
    </p><p>

To create all of the appropriate standard colormaps for a given visual on a
given screen, use
<code class="function">XmuVisualStandardColormaps</code>.

This function defines all appropriate standard colormap properties for the

<span class="symbol">True</span>,
any previous definition will be removed.
If retain is

To create a standard colormap if one does not currently exist, or replace
the currently existing standard colormap, use
<code class="function">XmuLookupStandardColormap</code>.

Given a screen, a visual, and a property, this function will determine the
best allocation for the property under the specified visual, and determine
the whether to create a new colormap or to use the default colormap of the
screen.
    </p><p>
If replace is True, any previous definition of the property will be
replaced.  If retain is True, the property and the colormap will be made
permanent for the duration of the server session.  However, pre-existing
property definitions which are not replaced cannot be made permanent by a
call to this function; a request to retain resources pertains to newly
created resources.
    </p><p>
This function returns 0 on failure, non-zero on success.  A request to
create a standard colormap upon a visual which cannot support such a map is
considered a failure.  An example of this would be requesting any standard
colormap property on a monochrome visual, or, requesting an
<span class="property">RGB_BEST_MAP</span> on
a display whose colormap size is 16.

To create any one standard colormap, use
<code class="function">XmuStandardColormap</code>.
    </p><p>
This function creates a standard colormap for the given screen, visualid,
and visual depth, with the given red, green, and blue maximum values, with
the given standard property name.  Upon success, it returns a pointer to an
<code class="function">XStandardColormap</code>
structure which describes the newly created colormap.
Upon failure, it returns <span class="symbol">NULL</span>.
If cmap is the default colormap of the screen, the standard colormap
will be defined on the default colormap; otherwise a new colormap is created.
    </p><p>
Resources created by this function are not made permanent; that is the
caller's responsibility.

To create any one colormap which is described by an
<span class="structname">XStandardColormap</span>
structure, use
<code class="function">XmuCreateColormap</code>.
    </p><p>
This function returns 0 on failure, and non-zero on success.  The base_pixel
of the colormap is set on success.  Resources created by this function are
not made permanent.  No argument error checking is provided; use at your own
risk.
    </p><p>
All colormaps are created with read-only allocations, with the exception of
read-only allocations of colors which fail
to return the expected pixel value, and these are individually defined as
read/write allocations.  This is done so that all the cells defined in the
colormap are contiguous, for use in image processing.  This typically
happens with White and Black in the default map.
    </p><p>
Colormaps of static visuals are considered to be successfully created if the
map of the static visual matches the definition given in the standard
colormap structure.

The functions defined in this section are for building a description of
the structure of and resources associated with a hierarchy of widget classes.
This package is typically used by applications that wish to manipulate the
widget set itself.
    </p><p>
The definitions needed to use these interfaces are in the header file
&lt;<code class="filename">X11/Xmu/WidgetNode.h</code>&gt;
<a id="idp38774224" class="indexterm"></a>.
To call these functions, you need to link against the libXmu library.
The following function must be called before any of the others described
below:

      </p><div class="funcsynopsis"><p><code class="funcdef">void <strong class="fsfunc">XmuWnInitializeNodes</strong>(</code>XmuWidgetNode *<var class="pdparam">node_array</var>, int <var class="pdparam">num_nodes</var><code>)</code>;</p></div><p>

    </p><p>
Each widget class inherits the resources of its parent.  To count the number
of resources contributed by a particular widget class, use:
