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

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. 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.
Specifies the background color for the widget.
Specifies a pixmap for tiling the background. The
first tile is placed at the upper left-hand corner
of the widget's window. Specifies the color of the
border in a pixel value. Specifies a pixmap to be
used for tiling the border. The first tile is
placed at the upper left-hand corner of the border.
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. 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. 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. Specifies
a list of callbacks that is called when the
widget is destroyed. Specifies the inside height
(excluding the border) of the widget's window.
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. 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. 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. 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 ancestorsensitive
flag of all its children is appropriately
set. Points to a translations list. A translations
list is a list of events and actions that are
to be performed when the events occur. Specifies
the inside width (excluding the border) of the widget's
window. 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. 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.
