Python

Question

他们是用来说明一些树的方法吗：

from anytree import Node, RenderTree

udo = Node("Udo")
marc = Node("Marc", parent=udo)
lian = Node("Lian", parent=marc)
dan = Node("Dan", parent=udo)
jet = Node("Jet", parent=dan)
jan = Node("Jan", parent=dan)
joe = Node("Joe", parent=dan)

在 tkinter 中作为表单的树视图：

[+]Udo
 ├──[+] Marc
 │   └──[+] Lian
 └── [+]Dan
      ├──[+] Jet
      ├──[+] Jan
      └──[+] Joe

与属性一起，单击 [+] 打开按钮本身右侧的节点子树。下图大概是我心目中的treeview：

找到了一些方法，但不知道他们是否有更好的方法来解决问题。

代码：

from anytree import Node, RenderTree, AsciiStyle, PreOrderIter
from tkinter import *
from tkinter import ttk


udo = Node("Udo")
marc = Node("Marc", parent=udo)
lian = Node("Lian", parent=marc)
dan = Node("Dan", parent=udo)
jet = Node("Jet", parent=dan)
jan = Node("Jan", parent=dan)
joe = Node("Joe", parent=dan)



class TreeView(Frame):
    def __init__(self, parent, tree):
        self.tree = tree
        self.treeview = ttk.Treeview(parent, height = 7)

    def generate(self):
        self.treeview.pack()

        index = 0

        for node in PreOrderIter(self.tree):
            self.treeview.insert('',f'{index}', node.name, text = node.name)
            index = index + 1

        for node in PreOrderIter(self.tree):
            for child in node.children:
                self.treeview.move(child.name, node.name, 'end')


root = Tk()

tv = TreeView(root, udo)
tv.generate()

root.mainloop()

输出：
