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).
