        finally:
            self.popup_menu.grab_release()

Answer 1

您正在将一个str传递给delete_selected，然后尝试读取它的x和y属性。不要将"<Button-3>"字符串传递给方法。相反，在lambda中接收event参数并将其传递给delete_selected。

self.popup_menu.add_command(label="stop process", command=lambda event:self.delete_selected(event))

或者简单地删除lambda并直接传递函数：

self.popup_menu.add_command(label="stop process", command=self.delete_selected)

Answer 2

这对我来说很管用

self.popup_menu.add_command(label="stop process",
                                    command=self.delete_selected)

        self.tree.bind('<Button-3>', self.popup)



def delete_selected(self):

    try:
        curItem = self.tree.item(self.tree.focus())
        item = self.tree.selection()[0]
        self.kill_process(curItem['values'])
        self.tree.delete(item)

    except:
         pass
