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
