Tkinter Treeview小部件上的右键菜单

Question

我正在尝试右键单击带有TTK的Treeview表中的特定行时，出现一个弹出菜单，该菜单对于每一行都是唯一的。

我发现了一些代码here，该代码可以满足我的需求，但是我不确定该代码是否有可能在一行或另一行的右键单击之间进行区分。下面是我的完整代码。

from tkinter import *
from tkinter import ttk
import sys

class Main:
    def __init__(self, root):
        pass

    def treeview_sort_column(self, tv, col, reverse):
        l = [(tv.set(k, col), k) for k in tv.get_children('')]
        try:
            l.sort(key=lambda t: int(t[0]), reverse=reverse)

        except ValueError:
            l.sort(reverse=reverse)

        for index, (val, k) in enumerate(l):
            tv.move(k, '', index)
        tv.heading(col, command=lambda: self.treeview_sort_column(tv, col, not reverse))

    def createWindow(self):
        self.popup = Menu(root, tearoff=0)
        self.popup.add_command(label="Shutdown") # , command=next) etc...
        self.popup.add_command(label="Edit Name")
        self.popup.add_separator()
        self.popup.add_command(label="Exit", command=lambda: self.closeWindow())

        Button(root, text="Exit", command=lambda: self.closeWindow()).pack()

        self.columns = ('Name', 'Age', 'Height')
        self.treeview = ttk.Treeview(root, columns=self.columns, show='headings')
        self.treeview.pack()
        self.treeview.insert('', 'end', values=("Josh", "18", "198"))
        self.treeview.insert('', 'end', values=("LJ", "36", "167"))
        self.treeview.insert('', 'end', values=("Klaudia", "12", "200"))
        self.treeview.insert('', 'end', values=("David", "74", "134"))

        self.treeview.bind("<Button-3>", self.do_popup)

        for col in self.columns:
            self.treeview.heading(col, text=col, command=lambda _col=col: \
                             self.treeview_sort_column(self.treeview, _col, False))

    def closeWindow(self):
        root.destroy()
        sys.exit()

    def do_popup(self, event):
        try:
            self.popup.tk_popup(event.x_root, event.y_root, 0)
        finally:
            self.popup.grab_release()

root = Tk()
X = Main(root)
X.createWindow()

root.mainloop()

您正在寻找的是树视图的identify_row()方法：

def do_popup(self, event):
    item = self.treeview.identify_row(event.y)
    print('clicked item:', item)
    try:
        self.popup.tk_popup(event.x_root, event.y_root, 0)
    finally:
        self.popup.grab_release()
