NAMEShell — The Shell widget class
SYNOPSIS
#include <Xm/Xm.h>
#include <X11/Shell.h>
DESCRIPTIONShell is a top-level widget (with only one managed child) that encapsu‐
lates 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 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).

XmNallowShellResize
Specifies that if this resource is False, the Shell widget
instance returns XtGeometryNo to all geometry requests from
its children. All Motif convenience create dialog functions
override this default value and set XmNallowShellResize to
True.
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 unreal‐
ized and the number of its managed children is changed. It is
used to change the values of the XmNx, XmNy, XmNwidth, and
XmNheight resources. When XtGetValues is called on this
resource, the returned value is a pointer to the actual
resource value and should not be freed. In addition, this
resource is not copied on creation or by XtSetValues. The
application must ensure that the string remains valid until
the shell is realized.
XmNoverrideRedirect
If True, specifies that the widget instance is a temporary
window that should be ignored by the window manager. Applica‐
tions 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. The second argument to
XtPopup must be XtGrabNone.
XmNsaveUnder
If True, specifies that 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, includ‐
ing always or never.
XmNvisual Specifies the visual used in creating the widget.
Inherited Resources
Shell inherits behavior and resources from the superclass described in
the following table. For a complete description of each resource,
refer to the reference page for that superclass.
