从主文件打开另一个 tkinter 程序 [英] Open another tkinter program from a main file

问题描述

我已经在我的主程序中尝试过

I have try this in my main program

from tkinter import *
import tkinter.filedialog
import os
root = Tk()
def open():
    PathPy = tkinter.filedialog.askopenfilename(title="Open a file",filetypes=[('PYTHON file','.py')])
    os.system(PathPy)
B = Button(root, text="Open a file", command=open).pack()
root.mainloop()

就在我的第二个文件中:

and just this in my second file:

from tkinter import *
root2 = Tk()
root2.mainloop()

当我选择 python 文件时，什么也没有发生......你能告诉我如何解决这个问题吗?

When I choose the python file, nothing happens... Can you please, tell me how to fix this ?

推荐答案

向您的代码添加两个内容可能会得到预期的结果.

os.system 需要一个命令"操作系统:

os.system expects a "command" for the operating system:

在子shell中执行命令(一个字符串).

Execute the command (a string) in a subshell.

像python3 myscript.py.

但是，由于您使用的是自定义 Python 编程环境，因此请传递 EduPython 的路径python.exe 到 os.system:

However, since you are using a custom python programming environment, pass the path of the EduPython's python.exe to os.system:

from tkinter import *
import tkinter.filedialog
import os
import sys

root = Tk()
pyexec = sys.executable

def open():
    PathPy = tkinter.filedialog.askopenfilename(title="Open a file",filetypes=[('PYTHON file','.py')])
    os.system('%s %s' % (pyexec, PathPy))

B = Button(root, text="Open a file", command=open).pack()
root.mainloop()

其次，将最后一行 root2.mainloop() 添加到您的第二个脚本中，使第二个 Tk 窗口出现.

Second, add the last line root2.mainloop() to your second script to make the second Tk window appear.

希望这会有所帮助.
