Shell

NAME

Shell — The Shell widget class "Shell" "widget class" "Shell"

SYNOPSIS

#include <Xm/Xm.h>
#include <X11/Shell.h>

DESCRIPTION

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. 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 unrealized 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. 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. 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, including 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.
