Shell is a top-level widget (with only one managed child) that encapsulates
the interaction with the window manager.
At the time the shell's child is managed, the child's width is used
for both widgets if the shell is unrealized and no width has been
specified for the shell. Otherwise, the shell's width is used for
both widgets. The same relations hold for the height of the shell and
its child.
Classes
Shell inherits behavior and resources from Composite
and Core.
The class pointer is shellWidgetClass.
The class name is Shell.
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).

XmNallowShellResize
Specifies that if this resource is False, the Shell widget instance
returns XtGeometryNo to all geometry requests from its children.
XmNcreatePopupChildProc
Specifies the pointer to a function that is called when the Shell
widget instance is popped up by XtPopup.
The function creates the child widget when the shell is popped up
instead of when the application starts up.
This can be used if the child needs to be reconfigured each time the
shell is popped up.
The function takes one argument, the popup shell, and returns no result.
It is called after the popup callbacks specified by
XmNpopupCallback.
XmNgeometry
Specifies the desired geometry for the widget instance. This resource
is examined only when the widget instance is unrealized and the number
of its managed children is changed. It is to change the values
of the XmNx, XmNy, XmNwidth, and
XmNheight resources.
XmNoverrideRedirect
Specifies this is True if the widget instance is a temporary
window which should be ignored by the window manager. Applications and
users should not normally alter this resource.
XmNpopdownCallback
Specifies a list of callbacks that is called when the widget instance
is popped down by XtPopdown.
XmNpopupCallback
Specifies a list of callbacks that is called when the widget instance
is popped up by XtPopup.
XmNsaveUnder
Specifies a True value if it is desirable to save the contents of the
screen beneath this widget instance, avoiding expose events when the
instance is unmapped. This is a hint, and an implementation may save
contents whenever it desires, including always or never.
XmNvisual
Specifies the visual used in creating the widget.
Inherited resources
Shell inherits behavior and resources from the following
superclass. For a complete description of each resource, refer to the
man page for that superclass.
