当用户单击Tkinter和Python 3中的按钮时,如何打开新窗口?
You can open a new window by creating a new instance of the Tkinter class Toplevel .
For example:
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()
