NAME
       PDL::Graphics::TriD::Tk - A Tk widget interface to the
       PDL::Graphics::TriD.

SYNOPSIS
        #
        # Opens a Tk window with an embedded TriD window - that's all
        # see Demos/TkTriD_demo.pm for a better example
        #
        use PDL;
        use PDL::Graphics::TriD;
        use PDL::Graphics::TriD::GL;
        use Tk;
        use PDL::Graphics::TriD::Tk;

        my $MW = MainWindow->new();
        my $TriDW = $MW->Tk( )->pack(-expand=>1, -fill=>'both');
        $TriDW->MainLoop;


DESCRIPTION
       The widget is composed of a Frame and the Display device
       of the TriD output.  It inherits all of the attributes of
       a Tk Frame.  All of the events associated with this window
       are handled through Tk with the exception of the <expose>
       event which must be handled by TriD because the Frame is
       never exposed.  Default Mouse bindings, defined for but-
       ton1 and button3, control TriD object orientation and size
       respectively.

FUNCTIONS
       Populate

       Used for widget initialization by Tk, this function should
       never be called directly

       MainLoop

       Should be used in place of the Tk MainLoop.  Handles all
       of the Tk callbacks and calls the appropriate TriD display
       functions.

       GLinit

       GLinit is called internally by a Configure callback in
       Populate.  This insures that the required Tk::Frame is
       initialized before the TriD::GL window that will go
       inside.

       refresh

       refresh() causes a display event to be put at the top of
       the TriD work que.  This should be called at the end of
       each user defined TriD::Tk callback.

       AUTOLOAD

       Trys to find a subroutine in PDL::Graphics::TriD when it
       is not found in this package.




       buttonmotion

       Default bindings for mousemotion with buttons 1 and 3
