Please help. Kindly explain thoroughly what each line does and if there is any better alternative to this lines of python code. I am trying to learn how to integrate Leap with a GUI using Tkinter. Many thanks! -------------------------------------------------------------------------------------------------------------------------- 

from Tkinter import Frame, Canvas, YES, BOTH import Leap class TouchPointListener(Leap.Listener): def on_init(self, controller): print "Initialized" def on_connect(self, controller): print "Connected" def on_frame(self, controller): self.paintCanvas.delete("all") frame = controller.frame() interactionBox = frame.interaction_box for pointable in frame.pointables: normalizedPosition = interactionBox.normalize_point(pointable.tip_position) if(pointable.touch_distance > 0 and pointable.touch_zone != Leap.Pointable.ZONE_NONE): color = self.rgb_to_hex((0, 255 - 255 * pointable.touch_distance, 0)) elif(pointable.touch_distance <= 0): color = self.rgb_to_hex((-255 * pointable.touch_distance, 0, 0)) #color = self.rgb_to_hex((255,0,0)) else: color = self.rgb_to_hex((0,0,200)) self.draw(normalizedPosition.x * 800, 600 - normalizedPosition.y * 600, 40, 40, color) def draw(self, x, y, width, height, color): self.paintCanvas.create_oval( x, y, x + width, y + height, fill = color, outline = "") def set_canvas(self, canvas): self.paintCanvas = canvas def rgb_to_hex(self, rgb): return '#%02x%02x%02x' % rgb class PaintBox(Frame): def __init__( self ): Frame.__init__( self ) self.leap = Leap.Controller() self.painter = TouchPointListener() self.leap.add_listener(self.painter) self.pack( expand = YES, fill = BOTH ) self.master.title( "Touch Points" ) self.master.geometry( "800x600" ) # create Canvas component self.paintCanvas = Canvas( self, width = "800", height = "600" ) self.paintCanvas.pack() self.painter.set_canvas(self.paintCanvas) def main(): PaintBox().mainloop() if __name__ == "__main__": main()
