on.paint

The function on.paint(gc) is called when the script's window needs to be painted.
'gc' is the Graphics Context, passed by default to the function.

This function can be flagged to fire by calling the platform.window:invalidate function.

Example

Below is an example of a program that uses on.paint(gc) to draw a line to the screen:

function on.paint(gc) --Define a function for the event with the default argument
	gc:drawLine(5,5,200,1) --Draw a line on the screen
end
