Core(3X)Core(3X)NAMECore - The Core widget class
SYNOPSIS
#include <Xm/Xm.h>
DESCRIPTIONCore 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 pro‐
grammer to specify data. The programmer can also set the resource val‐
ues 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 wid‐
get'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 cre‐
ated, the resources referenced by the widget are not reference
counted, regardless of how the resource type converter is regis‐
tered. 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 wid‐
get 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 Tool‐
kit 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 Intrin‐
sics' Event Manager dispatches to the widget all keyboard, mouse
button, motion, window enter/leave, and focus events. Insensi‐
tive widgets do not receive these events. Use the function
XtSetSensitive to change the sensitivity argument. Using XtSet‐
Sensitive ensures that if a parent widget has XmNsensitive set
to False, the ancestor-sensitive flag of all its children is
appropriately set. Points to a translations list. A transla‐
tions list is a list of events and actions that are to be per‐
formed 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 win‐
dow. 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.
Translations
There are no translations for Core.
