NAME
Core - The Core widget class.
SYNOPSIS
#include <Xm/Xm.h>
DESCRIPTION
Core is the Xt Intrinsic base class for windowed widgets. The Object and
RectObj classes provide support for windowless widgets.
Classes
All widgets are built from Core.
The class pointer is widgetClass.
The class name is Core.
New Resources
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).

XmNaccelerators
Specifies a translation table that is bound with its actions in the
context of a particular widget. The accelerator table can then be
installed on some destination widget.

XmNancestorSensitive
Specifies whether the immediate parent of the widget receives input
events. Use the function XtSetSensitive to change the argument to
preserve data integrity (see XmNsensitive below). For shells, the
default is copied from the parent's XmNancestorSensitive resource
if there is a parent; otherwise, it is True. For other widgets,
the default is the bitwise AND of the parent's XmNsensitive and
XmNancestorSensitive resources.
XmNbackground
Specifies the background color for the widget.
XmNbackgroundPixmap
Specifies a pixmap for tiling the background. The first tile is
placed at the upper left-hand corner of the widget's window.
XmNborderColor
Specifies the color of the border in a pixel value.
XmNborderPixmap
Specifies a pixmap to be used for tiling the border. The first
tile is placed at the upper left-hand corner of the border.
XmNborderWidth
Specifies the width of the border that surrounds the widget's
window on all four sides. The width is specified in pixels. A
width of zero means that no border shows.
XmNcolormap
Specifies the colormap that is used for conversions to the type
Pixel for this widget instance. When changed, previously generated
pixel values are not affected, but newly generated values are in
the new colormap. For shells without parents, the default is the
default colormap of the widget's screen. Otherwise, the default is
copied from the parent.
XmNdepth
Specifies the number of bits that can be used for each pixel in the
widget's window. Applications should not change or set the value
of this resource as it is set by the Xt Intrinsics when the widget
is created. For shells without parents, the default is the default
depth of the widget's screen. Otherwise, the default is copied
from the parent.
XmNdestroyCallback
Specifies a list of callbacks that is called when the widget is
destroyed.
XmNheight
Specifies the inside height (excluding the border) of the widget's
window.

XmNinitialResourcesPersistent
Specifies whether or not resources are reference counted. If the
value is True when the widget is created, the resources referenced
by the widget are not reference counted, regardless of how the
resource type converter is registered. An application that expects
to destroy the widget and wants to have resources deallocated
should specify a value of False. The default is True, implying an
assumption that the widget will not be destroyed during the life of
the application.
XmNmappedWhenManaged
If set to True it maps the widget (makes it visible) as soon as it
is both realized and managed. If set to False, the client is
responsible for mapping and unmapping the widget. If the value is
changed from True to False after the widget has been realized and
managed, the widget is unmapped.
XmNscreen
Specifies the screen on which a widget instance resides. It is
read only. When the Toolkit is initialized, the top-level widget
obtains its default value from the default screen of the display.
Otherwise, the default is copied from the parent.
XmNsensitive
Determines whether a widget receives input events. If a widget is
sensitive, the Xt Intrinsics' Event Manager dispatches to the
widget all keyboard, mouse button, motion, window enter/leave, and
focus events. Insensitive widgets do not receive these events.
Use the function XtSetSensitive to change the sensitivity argument.
Using XtSetSensitive ensures that if a parent widget has
XmNsensitive set to False, the ancestor-sensitive flag of all its
children is appropriately set.
XmNtranslations
Points to a translations list. A translations list is a list of
events and actions that are to be performed when the events occur.
XmNwidth
Specifies the inside width (excluding the border) of the widget's
window.
XmNx Specifies the x-coordinate of the upper left outside corner of the
widget's window. The value is relative to the upper left inside
corner of the parent window.
XmNy Specifies the y-coordinate of the upper left outside corner of the
widget's window. The value is relative to the upper left inside
corner of the parent window.
