可以使用^{}方法设置窗口的大小(可以是Tk实例或Toplevel实例)：
^{1}$
或者：
^{pr2}$
另外，使用几何方法还可以确定窗口的左上角：window.geometry('+{}+{}'.format(16, 32))
或者两者兼而有之：#identical to window.geometry('512x256+16+32')
window.geometry('{}x{}+{}+{}'.format(512, 256, 16, 32))
{a2的子窗口通常可以从一个更容易设置的窗口中使用}：widget.winfo_toplevel().geometry('{}x{}+{}+{}'.format(512, 256, 16, 32))
示例
下面是一个通过子控件的引用设置窗口的大小和位置坐标的示例：try: # In order to be able to import tkinter for
import tkinter as tk # either in python 2 or in python 3
except ImportError:
import Tkinter as tk
def on_button_press(widget):
width = 512
height = 256
x = 16
y = 32
widget.winfo_toplevel().geometry('{}x{}+{}+{}'.format(width, height, x, y))
if __name__ == '__main__':
root = tk.Tk()
window = tk.Toplevel(root)
button = tk.Button(window, text="Resize & Place")
#the line below is related to calling a method when a button is pressed
button['command'] = lambda w=button: on_button_press(w)
button.pack()
tk.mainloop()
