TriD::Tk(3pm)

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
button1 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
