Welcome to SEAT.
All functionality of python and this application is available through this command line
the variable 'window' contains a reference to your current window
here are some commands to get you started:
window.canvas.quickTextDraw('hello world',0,0); window.canvas.update();
window.canvas.displayData
happy scripting
