我正在尝试使用tkinter创建一个GUI来选择文本文件，最终结果是文件名以及用于其他程序的路径。文本文件可能不在同一文件夹中 GUI目前能够：
我为路径和文件名携带一个单独的StringVar，它与显示所选文件名的列表框小部件的索引匹配，或至少尝试。我没有找到一种方法来简单地添加或删除StringVar中的'line'，就像列表或数组一样。所以我尝试“提取”文件（通过将字符串转换回列表），以便使用.set将它们重写为相同的StringVar，但这并不是很好。主要问题是每次重写列表时我都会加倍'\'。
如果有人知道更容易/更好的实现方式，我希望，我在描述我会非常感谢输入或指导其他资源。如果您想使用它，则会附加代码。我也是python和tkinter的新手，所以如果你看到任何可以做得更好的事情，我也想听到。感谢您的任何意见。

答案 0 :(得分：0)
我会将我的值保存在iterable / sequence中，并通过调用以下函数绘制listbow小部件：
def redraw_listbox(w, seq):
w.delete(0, "end")
for i, elem in enumerate(seq):
w.insert(i, str(elem))
