XmPrimitive - The Primitive widget class
#include <Xm/Xm.h>
Primitive is a widget class used as a supporting superclass for other widget classes. It handles border drawing and highlighting, traversal activation and deactivation, and various callback lists needed by Primitive widgets.
Primitive inherits behavior and resources from Core class.
The class pointer is xmPrimitiveWidgetClass.
The class name is XmPrimitive.
The following table defines a set of widget resources used by the
programmer to specify data. The programmer can also set the resource
values for the inherited classes to set attributes for this widget. To
reference a resource by name or by class in a .Xdefaults
file, remove the XmN or XmC prefix
and use the remaining letters. To specify one of the defined values
for a resource in a .Xdefaults
file, remove the
Xm prefix and use the remaining letters (in either
lowercase or uppercase, but include any underscores between words).
The codes in the access column indicate if the given resource can be
set at creation time (C), set by using XtSetValues
(S), retrieved by using XtGetValues (G), or is not
applicable (N/A).

When a parent widget has an XmNnavigationType of XmEXCLUSIVE_TAB_GROUP, traversal of non-tab-group widgets within the group is based on the order of those widgets in their parent's XmNchildren list.
When any widget in a hierarchy has an XmNnavigationType of XmEXCLUSIVE_TAB_GROUP, traversal of tab groups in the hierarchy proceeds to widgets in the order in which their XmNnavigationType resources were specified as XmEXCLUSIVE_TAB_GROUP or XmSTICKY_TAB_GROUP, whether by creating the widgets with that value, by calling XtSetValues, or by calling XmAddTabGroup.
XmNunitType can have the following values:
The foreground, background, top shadow, bottom shadow, and highlight color resources are dynamically defaulted. If no color data is specified, the colors are automatically generated. On a single-plane system, a black and white color scheme is generated. Otherwise, four colors are generated, which display the correct shading for the 3-D visuals. If the background is the only color specified for a widget, the top shadow and bottom shadow colors are generated to give the 3-D appearance. Foreground and highlight colors are generated to provide sufficient contrast with the background color.
Colors are generated only at creation. Resetting the background through XtSetValues does not regenerate the other colors. XmChangeColor can be used to recalculate all associated colors based on a new background color.
Primitive inherits behavior and resources from the following superclass. For a complete description of each resource, refer to the man page for that superclass.

A pointer to the following structure is passed to each callback:
typedef struct { int reason; XEvent * event; } XmAnyCallbackStruct;
The XmPrimitive translations are listed below. These translations may not directly correspond to a translation table.
Note that for buttons in menus, altering translations in #override or #augment mode is undefined.

The XmPrimitive action routines are described below:
