1、鼠标和键盘事件

2、event 对象常用属性

3、源代码

from tkinter import *

window = Tk()
window.geometry("500x200")

w1 = Canvas(window, width=200, height=200, bg="red")
w1.pack()


def MouseTest(event):
    print("鼠标左键点击位置(相对于父容器):{0},{1}".format(event.x, event.y))
    print("鼠标左键点击位置(相对于屏幕):{0},{1}".format(event.x_root, event.y_root))
    print("事件绑定的组件:{0}".format(event.widget))


def TestDrag(event):
    w1.create_oval(event.x, event.y, event.x+1, event.y+1)


def KeyboardTest(event):
    print("键的keycode:{0}, 键的char:{1}, 键的keysym:{2}"
          .format(event.keycode, event.char, event.keysym))


def press_a_test(event):
    print("press a")


def release_a_test(event):
    print("release a")


w1.bind("<Button-1>", MouseTest)
# 将鼠标事件绑定到 MouseTest 方法
w1.bind("<B1-Motion>", TestDrag)

window.bind("<KeyPress>", KeyboardTest)
window.bind(("<KeyPress-a>", press_a_test))
window.bind("<KeyRelease-a>", release_a_test)

window.mainloop()
