Tkinter 树视图显示和选择行问题

Question

我想将以下字符串插入到树视图中并显示完整的字符串，但是当我运行代码时，该字符串没有完全显示在树视图中。我还想选择树视图中的行来取回字符串，该字符串在某种程度上是正确的，但与最初插入的字符串不同。我正在使用Python 3.6。下面是我正在使用的代码和我观察到的一些示例输出。请就两件事向我提出建议：

1. 如何保证插入的字符串在treeview中显示一模一样？
2. 当我选择该行数据并按回车键时，如何将其恢复为最初插入的字符串？

import tkinter as tk
import tkinter.ttk
selected_from_list = []
def select():
    curItems = tree.selection()
    for x in curItems:
        print(x)
        selected_from_list.append(tree.item(x)['values'])
        print(selected_from_list)
    print(selected_from_list)
    print([str(tree.item(i)['values']) for i in curItems])
    tk.Label(root, text="\n".join([str(tree.item(i)['values']) for i in curItems])).pack()

root = tk.Tk()
tree = tkinter.ttk.Treeview(root, height=4)

tree['show'] = 'headings'
tree['columns'] = ('File path')
tree.heading("#1", text='Badge Name', anchor='w')
tree.column("#1", stretch="no")
tree.pack()

tree.insert("", "end", values="C:/Users/PB/PyProjects/VA_PY_36/Python Excel project/people 1.xlsx")
tree.insert("", "end", values="C:/Users/PB/PyProjects/VA_PY_36/Python Excel project/people 2.xlsx")
tree.insert("", "end", values="C:/Users/PB/PyProjects/VA_PY_36/Python Excel project/people 3.xlsx")

tree.bind("<Return>", lambda e: select())

root.mainloop()

感谢您抽出时间来指导新手编码器！我非常感谢您的意见！

我尝试调整树视图宽度，但似乎没有什么区别

Answer 1

请注意，

columns

和

values

选项都需要一个元组/列表，但您向它们传递了一个字符串。看起来字符串将被底层 TCL 解释器隐式地用空格分割，您将得到发布图像中显示的内容。

将正确的类型传递给以下两个选项：

...
tree['columns'] = ('File path',)  # changed to tuple by adding a comma before the ending )
...
tree.column("#1", stretch="no", width=400) # set larger width to show the content
...
# pass list to values option
tree.insert("", "end", values=["C:/Users/PB/PyProjects/VA_PY_36/Python Excel project/people 1.xlsx"])
tree.insert("", "end", values=["C:/Users/PB/PyProjects/VA_PY_36/Python Excel project/people 2.xlsx"])
tree.insert("", "end", values=["C:/Users/PB/PyProjects/VA_PY_36/Python Excel project/people 3.xlsx"])
...

结果：
