TKinter 打开文件对话框是否有替代方案？

Question

我正在使用 pygame 制作一个小型 2d 游戏引擎，我想打开文件对话框。我能找到的唯一选择是 tkinter，当我运行这段代码时

root = Tk()
*code here*
filedialog.askopenfile(initialdir="/", title="Select A File",
                                                      filetypes=(
                                                          ("Png Files", "*.png"), ("Jpg Files", "*.jpg"))).name
*code here*
root.mainloop()

除了另一个白色 GUI 正在打开之外，一切都按预期工作，所以我删除了 mainloop() 和 root = Tk() 行，但它给了我一个错误

错误是这样的：

Answer 1

#! /usr/bin/env python3
import easygui as g

title = 'Choose your destiny'
filename = g.fileopenbox( title )

file = open( filename )

Python 有打开文件的能力，实际上就是file = open('filename.ext') 但是 pygame 不会为你做文件系统遍历。

因此，您需要找到一个可以打印目录内容的库，并允许您从该列表中进行选择，或者进行选择。 EasyGUI 简化了该过程，因为您不必寻找解决方案，只要它就在那里。

在不涉及 pygame 的情况下运行这段代码， 这样你就可以看到它做了什么。如果它给你一个对话框，并返回文件，那么你很高兴。只需从该点初始化 pygame，然后从那里开始。
