按钮代码:

感谢任何帮助.

b1 = Button(window, text = "Import", width = 12, command = functionOne)
b1.grid(row = 0, column = 2)

推荐答案

你可以这样做 - 而不是设置按钮的 command 关键字参数，只需将按钮捕获的不同事件绑定到不同的职能.这里有一些关于事件和绑定事件的更多信息.

You can do something like this - Instead of setting the button's command keyword argument, just bind different events captured by the button to different functions. Here's some more info about events and binding events.

import tkinter as tk


class Application(tk.Tk):

    def __init__(self, *args, **kwargs):
        tk.Tk.__init__(self, *args, **kwargs)
        self.title("Test")
        self.geometry("128x32")
        self.resizable(width=False, height=False)

        self.button = tk.Button(self, text="Try Me")
        self.button.pack()

        self.button.bind("<Button-1>", self.normal_click)
        self.button.bind("<Shift-Button-1>", self.shift_click)

    def normal_click(self, event):
        print("Normal Click")

    def shift_click(self, event):
        print("Shift Click")


def main():

    application = Application()
    application.mainloop()

    return 0


if __name__ == "__main__":
    import sys
    sys.exit(main())
