使用交互式ipython Notebook运行Tkinter [英] Running Tkinter with interactive ipython notebook

问题描述

我想创建一个交互式的python编码游戏，用户可以在其中输入命令到jupyter笔记本中，并在GUI上实时查看结果.这似乎在常规的python交互式shell中可以正常工作.我运行它的方式如下:

I want to create an interactive python coding game, where users can enter commands into a jupyter notebook and see the result on a GUI in real time. This seems to work fine in the regular python interactive shell. The way I get this to run is the following:

1. 我制作了一个文件，使用以下代码将其命名为example.py:

import tkinter as tk


def create_canvas():
    root = tk.Tk()
    root.resizable(False, False)
    root.title("Karel")
    frame = tk.Frame(root)
    frame.pack()
    canvas = tk.Canvas(frame, bg="white", width=500, 
        height=500)
    canvas.pack()
    return canvas


def create_oval(canvas):
    return canvas.create_oval(150, 150, 155, 155, fill='#000')



def move(canvas, oval):
    canvas.move(oval, 0, -50)

1. 然后在交互式python shell中执行以下操作:

>> import example
>> canvas = example.create_canvas()
>> oval = example.create_oval(canvas)

但是，当我尝试在ipython中使用它时，我没有看到GUI(我假设这是因为我不执行tkinters mainloop函数).但是，如果我确实执行了mainloop函数，那么我将无法再在交互式python shell中输入用户类型.

However, when I try to get this working in ipython, I don't see a GUI (I'm assuming this is because I don't execute tkinters mainloop function). But if I do execute the mainloop function, then I can't have the user type in an interactive python shell anymore.

所以我的问题是，如何使ipython(以便可以使用jupyter笔记本)表现得像python并显示GUI而不阻止来自控制台的用户输入?

So my question, is how do I get ipython (so I can use jupyter notebooks) to behave like python and display the GUI without blocking user input from the console?

:我想出了如何使用ipython做到这一点. 我必须输入ipython --gui 'tk'，但是如何将ipython选项传递给jupyter笔记本服务器，以便可以在笔记本中完成所有操作?

: I figured out how to do it with ipython. I have to type ipython --gui 'tk' but how do I pass ipython options to a jupyter notebook server so that I can do this all in a notebook?

推荐答案

好的，我知道了.

关键是要添加以下行: %gui tk在笔记本的开头.这样做与ipython的--gui 'tk选项类似.

The key is to put the line: %gui tk at the start of the notebook. This does something similar to the --gui 'tk option for ipython.
