NAME

       Tk::MainWindow - Root widget of a widget tree

SYNOPSIS

	   use Tk;

	   my $mw = MainWindow->new( ... options ... );

	   my $this = $mw->ThisWidget -> pack ;
	   my $that = $mw->ThatWidget;
	   ...

	   MainLoop;

DESCRIPTION

       Perl/Tk applications (which have windows associated with them) create one or more MainWindows which act as the containers and parents of
       the other widgets.

       Tk::MainWindow is a special kind of Toplevel widget. It is the root of a widget tree. Therefore "$mw->Parent" returns "undef".

       The default title of a MainWindow is the basename of the script (actually the Class name used for options lookup, i.e. with basename with
       inital caps) or 'Ptk' as the fallback value.  If more than one MainWindow is created or several instances of the script are running at the
       same time the string " #n" is appended where the number "n" is set to get a unique value.

       Unlike the standard Tcl/Tk's wish, perl/Tk allows you to create several MainWindows.  When the last MainWindow is destroyed the Tk
       eventloop exits (the eventloop is entered with the call of "MainLoop"). Various resources (bindings, fonts, images, colors) are maintained
       or cached for each MainWindow, so each MainWindow consumes more resources than a Toplevel. However multiple MainWindows can make sense when
       the user can destroy them independently.

METHODS

       You can apply all methods that a Toplevel widget accepts.

       The method $w->MainWindow applied to any widget will return the MainWindow to which the widget belongs (the  MainWindow belongs to itself).

MISSING

       Documentation is incomplete.  Here are some missing items that should be explained in more detail:

       o   The new mechanism for MainWindows is slightly different to other widgets.

       o   There no explanation about what resources are bound to a MainWindow (e.g., ClassInit done per MainWindow)

       o   Passing of command line options to override or augment arguments of the "new" method (see Tk::CmdLine).

NAME

       XmVaCreateMainWindow, XmVaCreateManagedMainWindow -- A MainWindow widget convenience creation functions.

SYNOPSIS

       #include <Xm/MainW.h>

       Widget XmVaCreateMainWindow(
       Widget parent,
       String name,
       ...);

       Widget XmVaCreateManagedMainWindow(
       Widget parent,
       String name,
       ...);

DESCRIPTION

       These  functions  create  an instance of a MainWindow widget and returns the associated widget ID.  These routines use the ANSI C variable-
       length argument list (varargs) calling convention.

       The XmVaCreateMainWindow function is a convenience routine that calls XtCreateWidget.

       The XmVaCreateManagedMainWindow function is a convenience routine that calls XtCreateManagedWidget.

       parent	 Specifies the parent widget ID.

       name	 Specifies the name of the created widget.

       ...	 Specifies the variable argument list to override the resource defaults.

       For a complete definition of MainWindow and its associated resources, see XmMainWindow(3).

RETURN

       Returns the MainWindow widget ID.
