NAME
XmMainWindow — The MainWindow widget class "XmMainWindow" "widget class" "MainWindow"
SYNOPSIS
#include <Xm/MainW.h>
DESCRIPTION
MainWindow provides a standard layout for the primary window of an application. This layout includes a
MenuBar, a CommandWindow, a work region, a MessageWindow, and ScrollBars. Any or all of these areas are
optional. The work region and ScrollBars in the MainWindow behave identically to the work region and
ScrollBars in the ScrolledWindow widget. The user can think of the MainWindow as an extended
ScrolledWindow with an optional MenuBar and optional CommandWindow and MessageWindow.
In a fully loaded MainWindow, the MenuBar spans the top of the window horizontally. The CommandWindow
spans the MainWindow horizontally just below the MenuBar, and the work region lies below the
CommandWindow. The MessageWindow is below the work region. Any space remaining below the MessageWindow
is managed in a manner identical to ScrolledWindow. The behavior of ScrolledWindow can be controlled by
the ScrolledWindow resources. To create a MainWindow, first create the work region elements, a MenuBar,
a CommandWindow, a MessageWindow, a horizontal ScrollBar, and a vertical ScrollBar widget, and then call
XmMainWindowSetAreas with those widget IDs.
MainWindow can also create three Separator widgets that provide a visual separation of MainWindow's four
components. The user can specify resources in a resource file for the automatically created gadgets that
contain the MainWindow separators. The name of the first separator gadget is Separator1; the second is
Separator2; and the third is Separator3.
MainWindow also provides the following three child types for layout at creation time:
• XmMENU_BAR
• XmCOMMAND_WINDOW
• XmMESSAGE_WINDOW
MainWindow can use these child types at creation time instead of their associated resource values.
MainWindow uses the XmQTmenuSystem trait.
Descendants
MainWindow automatically creates the descendants shown in the following table. An application can use
XtNameToWidget to gain access to the named descendant. In addition, a user or an application can use the
named descendant when specifying resource values.
┌─────────────────┬───────────────────┬───────────────────────────┐

Classes
MainWindow inherits behavior and resources from Core, Composite, Constraint, XmManager, and
XmScrolledWindow.
The class pointer is xmMainWindowWidgetClass.
The class name is XmMainWindow.
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).
