Create a frame and assign callbacks to event handlers

frame = simplegui.create_frame("Draw", 500, 500) frame.set_canvas_background('white') frame.add_label('- Please select shape - ') frame.add_button('circle',circle,100) frame.add_button("square", square,100) frame.add_button("triangle", triangle,100) frame.add_label(' ') color_input = frame.add_input('- Please input color as red/blue/#FF00EE',color_input,100) color_input.set_text('red') frame.add_label(' ') frame.add_button('review-by-step',review_step,200) frame.add_label(' ') interval_input = frame.add_input('- review interval as millisecond',set_interval,100) interval_input.set_text('500') frame.add_button('auto review/stop review',auto_review,200) frame.set_draw_handler(draw) frame.set_mouseclick_handler(click) timer = simplegui.create_timer(interval,timer_handler)

Start the frame animation

frame.start()
