[PYTHON/COMMON] Canvas 클래스 : bind_all 메소드를 사용해 이벤트 핸들러 설정하기

■ Canvas 클래스의 bind_all 메소드를 사용해 이벤트 핸들러를 설정하는 방법을 보여준다.

▶ 예제 코드 (PY)


from tkinter import *

tk = Tk()

canvas = Canvas(tk, width = 500, height = 500)

canvas.pack()

canvas.create_polygon(10, 10, 10, 60, 50, 35)

def moveTriangle(event):
    if event.keysym == "Up":
        canvas.move(1, 0, -3)
    elif event.keysym == "Down":
        canvas.move(1, 0, 3)
    elif event.keysym == "Left":
        canvas.move(1, -3, 0)
    else:
        canvas.move(1, 3, 0)

canvas.bind_all("<KeyPress-Up>"   , moveTriangle)
canvas.bind_all("<KeyPress-Down>" , moveTriangle)
canvas.bind_all("<KeyPress-Left>" , moveTriangle)
canvas.bind_all("<KeyPress-Right>", moveTriangle)

tk.mainloop()
