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).
