Question

我试图在选择事件时返回tkinter树视图选择的父级，因此如果选择更改为＆＃34; child＆＃34;我希望打印＆＃34; parent＆＃34;，下面的工作示例，目前它打印的是选择，而不是选择的父级：

try:
    import tkinter as tk
    import tkinter.ttk as ttk
except ImportError:
    import Tkinter as tk
    import ttk

class App:
    def __init__(self):
        self.root = tk.Tk()
        self.tree = ttk.Treeview(selectmode='browse')
        self.tree.pack(side="top", fill="both")
        self.tree.bind('<<TreeviewSelect>>', self.tree_select_event)
        self.parent_iid = self.tree.insert("", "end", text="Parent")
        self.child_iid = self.tree.insert(self.parent_iid, "end", text="Child")

        self.root.mainloop()

    def tree_select_event(self, event):
        print (self.tree.item(self.tree.selection()[0])['text'])

if __name__ == "__main__":
    app = App()

目前在选择Child时打印：

"Child"

选择孩子时所需的输出：

"Parent"

试试这个：

def tree_select_event(self, event):
    item_iid = self.tree.selection()[0]
    parent_iid = self.tree.parent(item_iid)

    if parent_iid:
        print(self.tree.item(parent_iid)['text'])
    else:
        print(self.tree.item(item_iid)['text'])

..并且记录良好here。
