如何通过 tkinter 模块中的绑定传递我的变量？

  • 772

资源：

from tkinter import Tk, Button, Canvas

root = Tk()

c = Canvas(root,width=100,height=100)
c.pack()

def opt(event):
    print(url1)

url1 = "vk.com"
url2 = "ok.ru"

but1 = Button(text="Vk")
but1.bind(sequence="<Button-3>",func=opt)
but1.pack()

but2 = Button(text="Ok")
but2.bind(sequence="<Button-3>",func=opt)
but2.pack()

root.mainloop()

如何做到这一点，以便在单击按钮时将 vk 传递给url1 = "vk.com" 函数并写入"vk.com".

如果你点击 ok，那么 url 就会被传输url2 = "ok.ru" 并写入"ok.ru"

只需要按"<Button-3>"

    利用 lambda

    from tkinter import Tk, Button, Canvas


def opt(items):
    print(items)


root = Tk()

c = Canvas(root, width=100, height=100)
c.pack()

url1 = "vk.com"
url2 = "ok.ru"

but1 = Button(text="Vk")
but1.bind(sequence="<Button-3>", func=lambda event: opt(url1))
but1.pack()

but2 = Button(text="Ok")
but2.bind(sequence="<Button-3>", func=lambda event: opt(url2))
but2.pack()

root.mainloop()
