-A resource is a field in the widget record with a corresponding
-resource entry in the \fIresources\fP list of the widget or any of its
-superclasses.
-This means that the field is
-settable by
-.PN XtCreateWidget
-(by naming the field in the argument list), by an
-entry in a resource file (by using either the name or class), and by
-.PN XtSetValues .
-In addition, it is readable by
-.PN XtGetValues .
-Not all fields in a widget record are resources.
-Some are for bookkeeping use by the
-generic routines (like \fImanaged\fP and \fIbeing_destroyed\fP).
-Others can be for local bookkeeping,
-and still others are derived from resources 
-(many graphics contexts and pixmaps).
-.LP
-Widgets typically need to obtain a large set of resources at widget
-creation time.
-Some of the resources come from the argument list supplied in the call to
-.PN XtCreateWidget ,
-some from the resource database,
-and some from the internal defaults specified by the widget.
-Resources are obtained first from the argument list,
-then from the resource database for all resources not specified
-in the argument list,
-and last, from the internal default, if needed.

-A resource entry specifies a field in the widget,
-the textual name and class of the field that argument lists
-and external resource files use to refer to the field,
-and a default value that the field should get if no value is specified.

-.PN XtResource

-When the resource list is specified as the
-.PN CoreClassPart ,
-.PN ObjectClassPart ,
-.PN RectObjClassPart ,
-or
-.PN ConstraintClassPart
-\fIresources\fP field, the strings pointed to by \fIresource_name\fP,
-\fIresource_class\fP, \fIresource_type\fP, and \fIdefault_type\fP must
-be permanently allocated prior to or during the execution of the class
-initialization procedure and must not be subsequently deallocated.
-
-.LP
-The \fIresource_name\fP field contains the name used by clients to access the field
-in the widget.
-By convention, it starts with a lowercase letter
-and is spelled exactly like the field name,
-except all underscores (_) are deleted and the next letter is replaced by its 
-uppercase counterpart.
-For example, the resource name for background_pixel becomes backgroundPixel.
-Resource names beginning with the two-character
-sequence ``xt'', and resource classes beginning with the two-character
-sequence ``Xt'' are reserved to the \*(xI for future standard and
-implementation-dependent uses.
-Widget header files typically contain a symbolic name for each resource name.
-All resource names, classes, and types used by the \*(xI are named in
-.Pn < X11/StringDefs.h >.
-The \*(xI's symbolic resource names begin with
-``XtN''
-and are followed by the string name (for example, XtNbackgroundPixel
-for backgroundPixel).
-
-.LP
-The \fIresource_class\fP field contains the class string used in resource
-specification files to identify the field.
-A resource class provides two functions:
-.IP \(bu 5
-It isolates an application from different representations that widgets 
-can use for a similar resource.
-.IP \(bu 5
-It lets you specify values for several actual resources with a single name.
-A resource class should be chosen to span a group of closely related fields.
-.LP
-For example,
-a widget can have several pixel resources: background, foreground,
-border, block cursor, pointer cursor, and so on.
-Typically, the background defaults to white
-and everything else to black.
-The resource class for each of these resources in the resource list
-should be chosen so that it takes the minimal number of entries
-in the resource database to make the background ivory
-and everything else darkblue.
-.LP
-In this case, the background pixel should have a resource class of
-``Background''
-and all the other pixel entries a resource class of
-``Foreground''.
-Then, the resource file needs only two lines to
-change all pixels to ivory or darkblue:
-.LP
-.Ds 5
-.TA .5i 1.5i
-.ta .5i 1.5i
-*Background:	ivory
-*Foreground:	darkblue
-.De
-.LP
-Similarly, a widget may have several font resources (such as normal and bold),
-but all fonts should have the class Font.
-Thus, changing all fonts simply requires only a single line in the 
-default resource file:
-.LP
-.Ds 5
-.TA .5i 3i
-.ta .5i 3i
-*Font:	6x13
-.De
-.LP
-By convention,
-resource classes are always spelled starting with a capital letter
-to distinguish them from resource names.
-Their symbolic names are preceded with
-``XtC''
-(for example, XtCBackground).
-.LP
-The \fIresource_type\fP field gives the physical representation type of the resource
-and also encodes information about the specific usage of the field.
-By convention, it starts with an uppercase letter and is
-spelled identically to the type name of the field.
-The resource type is used when resources are fetched to
-convert from the resource database format (usually
-.PN String )
-or the format of the resource default value
-(almost anything, but often
-.PN String )
-to the desired
-physical representation (see Section 9.6).
-The \*(xI define the following resource types:

-convenience for widgets, although they do not have any corresponding
-data type assigned:
-.PN XtREditMode ,
-.PN XtRJustify ,
-and
-.PN XtROrientation .
-.LP
-The \fIresource_size\fP field is the size of the physical representation in bytes;
-you should specify it as
-.PN sizeof (\fItype\fP)
-so that the
-compiler fills in the value.
-The \fIresource_offset\fP field is the offset in bytes of the field 
-within the widget.
-You should use the
-.PN XtOffsetOf
-macro to retrieve this value.
-The \fIdefault_type\fP field is the representation type of the default
-resource value.
-If \fIdefault_type\fP is different from \fIresource_type\fP and the default value
-is needed,
-the resource manager invokes a conversion procedure from \fIdefault_type\fP
-to \fIresource_type\fP.
-Whenever possible,
-the default type should be identical to the resource type in order
-to minimize widget creation time.
-However, there are sometimes no values of the type that the program 
-can easily specify.
-In this case,
-it should be a value for which the converter is guaranteed to work (for example, 
-.PN XtDefaultForeground
-for a pixel resource).
-The \fIdefault_addr\fP field specifies the address of the default resource value.
-As a special case, if \fIdefault_type\fP is
-.PN XtRString ,
-then the value in the \fIdefault_addr\fP field is the pointer to
-the string rather than a pointer to the pointer.
-The default is used if a resource is not specified in the argument list
-or in the resource database or if the conversion from the representation
-type stored in the resource database fails,
-which can happen for various reasons (for example, a misspelled entry in a
-resource file).
-.LP
-Two special representation types 
-(XtRImmediate
-and
-XtRCallProc)
-are usable only as default resource types.
-XtRImmediate
-indicates that the value in the \fIdefault_addr\fP field is the actual value of
-the resource rather than the address of the value. 
-The value must be in the correct representation type for the resource,
-coerced to an
-.PN XtPointer .
-No conversion is possible, since there is no source representation type.
-XtRCallProc
-indicates that the value in the \fIdefault_addr\fP field is a procedure
-pointer.
-This procedure is automatically invoked with the widget,
-\fIresource_offset\fP, and a pointer to an
-.PN XrmValue

-In general, if a widget resource field is declared in a superclass,

-If the set_values procedure needs to call any routines that operate on

-Before calling the set_values procedures, the \*(xI modify the

-After calling all the set_values procedures,
