从运动绑定事件更新tkinter标签中的文本

Question

我能够将数据从一个类帧移动到另一个类帧，遗憾的是，我无法更新新帧中的文本。我只能将新数据打包到原始包装

之下

class LabelApp(tk.Frame):
    def __init__(self, master, xy_motion=[-1,-1]):
        tk.Frame.__init__(self, master )
        self.pack()
        print('LapApp: ' + str(xy_motion[0]))
        self.master = master
        self.xy_motion=xy_motion
        self.xlabel = tk.Label(text=self.xy_motion[0])
        self.xlabel.pack()


    def update_label(self, xy_motion ):
        self.xlabel.config(text=xy_motion[0])

上面的print语句显示正确的数据

传递数据的代码

class VideoDisplayApp(tk.Frame):
    def __init__(self, master):
        tk.Frame.__init__(self, master)
        self.pack()
        self.master = master
        self.image_label = tk.Label(master=self.master)  # label for the vide.
..
.
.

def motion(self, event):
    x, y = event.x, event.y
    self.xy_motion = [x,y]
    print('{}, {}'.format(x, y))
    self.motion=tk.Frame(self.master)
    self.app = LabelApp(self.motion, self.xy_motion )

主窗口

class MainWindow(tk.Frame):
    def __init__(self, master):
        tk.Frame.__init__(self, master)
        self.pack(padx=15, pady=15)
        self.master.title("Mob")
        self.master.resizable(False, False)
        self.master.tk_setPalette(background='#e6e6e6')

        frame_video = tk.Frame(self)
        frame_video.grid(row=0, column=0)
        # frame_video.geometry("200x200")
        VideoDisplayApp(frame_video)
        #
        frame_bottom = tk.Frame(self)
        frame_bottom.grid(row=1, column=0)
        LabelApp(frame_bottom)
        #
        frame_left = tk.Frame(self)
        frame_left.grid(row=0, column=1)
        ClickOnFrame(frame_left)
