Python 3 和 tkinter 通过单击按钮打开新窗口

Question

当用户单击 Tkinter 和 Python 3 中的按钮时如何打开新窗口？

Answer 1

您可以通过创建 Tkinter 类的新实例来打开新窗口 Toplevel .

例如:

import Tkinter as tk

class View(tk.Frame):
    count = 0
    def __init__(self, *args, **kwargs):
        tk.Frame.__init__(self, *args, **kwargs)
        b = tk.Button(self, text="Open new window", command=self.new_window)
        b.pack(side="top")

    def new_window(self):
        self.count += 1
        id = "New window #%s" % self.count
        window = tk.Toplevel(self)
        label = tk.Label(window, text=id)
        label.pack(side="top", fill="both", padx=10, pady=10)

if __name__ == "__main__":
    root = tk.Tk()
    view = View(root)
    view.pack(side="top", fill="both", expand=True)
    root.mainloop()
