如何在不同的窗口中获取条目文本? [英] How to fetch the entry text on a different window?
问题描述
我正在尝试创建一个允许用户通过条目小部件输入用户名"的游戏.撇开整个游戏方面不谈，现在我只需要一个加载标题屏幕的程序，然后单击一个按钮会出现一个新的设置"窗口，提示我输入我的用户名，然后单击一个按钮，设置窗口就会出现离开，我有我的游戏窗口，上面有一个标签，上面写着用户名:[你的名字在这里]".
谁能帮我解决这个问题?
(这是我目前正在处理的代码

我希望这段代码能够帮助您弄清楚如何实现弹出文本对话框.这个例子的工作方式是在主窗口(root)中实现一个按钮，当你点击它时，弹出的对话框会出现MyDialog类对象，会被创建，然后会使用wait_window() 等待它完成.可以看到弹出的对话框是如何实现的，就是一个简单的, stackoverflow，tutorialspoint, daniweb
I am trying to create a game that allows the user to input a "username" through an entry widget. Setting aside the whole game aspect, for now I just need a program that loads up a title screen, then on clicking a button a new "setup" window appear prompting me to enter my username, then on clicking a button there the setup window goes away and I have my game window, with a label that reads "USERNAME: [your name here]".
Can anyone help me with this?

Sorry for the code being half in spanish, you should still get what's going on though).
I hope this piece of code will able to help you figure out how to implement the pop up text dialog box. The way of this example work by implementing a button in the main window (root), when you click on it, the pop up dialog will appear MyDialog class object, will be created, then it will use wait_window() to wait until it is finish. You can see how the pop up dialog box is implemented, it is an simple TopLevel widget, it is just like another frame you can think of, you pack your label, your Entry field, and finally a button mySubmitButton.
Look down to the send function, it is pretty much just getting the entry using simple .get() method from the Entry. And then you will destory() the window, and resume back the main window. You can do it as many time as you want.
import tkinter as tk
class MyDialog:
def __init__(self, parent):
top = self.top = tk.Toplevel(parent)
self.myLabel = tk.Label(top, text='Enter your username below')
self.myLabel.pack()
self.myEntryBox = tk.Entry(top)
self.myEntryBox.pack()
self.mySubmitButton = tk.Button(top, text='Submit', command=self.send)
self.mySubmitButton.pack()
def send(self):
global username
username = self.myEntryBox.get()
self.top.destroy()
def onClick():
inputDialog = MyDialog(root)
root.wait_window(inputDialog.top)
print('Username: ', username)
username = 'Empty'
root = tk.Tk()
mainLabel = tk.Label(root, text='Example for pop up input box')
mainLabel.pack()
mainButton = tk.Button(root, text='Click me', command=onClick)
mainButton.pack()
root.mainloop()
In the sample output I did it two times. Entered George and Sam (my friend) as username, and the username will be updated everytime you open up a new dialog box.
Output:
>>> ================================ RESTART ================================
>>>
Username: George
Username: Sam
Edit: The submit button seems to be buggy? It sometimes doesn't want to be appear. It is clickable, but it does not appear until it is clicked. It appears to be only problem for Mac OS.
