Python TksimpleDialog 定位在根窗口旁边 [英] Python TksimpleDialog positioning next to the root window

问题描述

我正在尝试打开一个简单的对话窗口，用户可以在其中根据根窗口上显示的菜单输入一个选项.然而，当我运行代码时，对话框会直接在根窗口中的菜单上方打开，使其看不见.有没有办法打开对话框，使其在根窗口旁边打开，如附图所示.

I am trying to open a simple dialog window, in which the user enters a choice based on a menu presented on the root window. When I run the code however the dialog opens directly above the menu in the root window obscuring it from sight. Is there a way to open the dialog so it opens next to the root window as shown in the attached image.

我已经检查了这个link 似乎没有任何定位简单对话框的参数.我也尝试过使用 toplevel，但是打开多个窗口时它变得混乱.

I have checked this link and it does not seem there is any positioning arguments for simple dialogs. I have also tried with toplevel but it got messy with multiple windows open.

我的代码如下:

from Tkinter import *
import tkSimpleDialog

root = Tk()
root.lift()


Label(root, text = "Menu Choices:").grid(row=1, column =0)
Label(root, text='1. Baloney and cheese').grid(row=2, column=0, pady=4)
Label(root, text='2. Roast chicken and gravy').grid(row=3, column=0, pady=4)
Label(root, text='3. Pear salad').grid(row=4, column=0, pady=4)
Label(root, text='4. Cateloupe and brocoli soup').grid(row=5, column=0, pady=4)

people = ["Liam","Henry","Paula"]

menuChoice = []

for i in people:
    c = tkSimpleDialog.askinteger('Franks Restaurant', 'Please choose your meal?', parent = root)
    menuChoice.append(c)

root.mainloop()

推荐答案

虽然 Tk 库名义上是私有的"，但它实际上有一个执行此操作的函数.您可以按如下方式使用它.

the Tk library actually has a function that does this although it is nominally 'private'. You can use it as follows.

import tkinter as tk

root = tk.Tk()
root.wm_geometry("800x600")
dialog = tk.Toplevel(root)
root_name = root.winfo_pathname(root.winfo_id())
dialog_name = dialog.winfo_pathname(dialog.winfo_id())
root.tk.eval('tk::PlaceWindow {0} widget {1}'.format(dialog_name, root_name))
root.mainloop()

这会将您的对话框置于指定窗口(在本例中为根窗口)上方的中心.

This will place your dialog centred over the specified window (in this case th root window).
