Python tkinter框架画布调整大小

我正在尝试调整画布大小，以便当用户在窗口边缘使用“单击并拖动”调整窗口大小时，画布会填满整个窗口，但我没有成功 .

我看过以下其他问题：

问题＃1（之前发布，但没有帮助）

这个发送给我的是我认为正确的方向，因为我在画布上绑定了一个Configure . 但是，我得到一个错误，“'画布'没有在FrameWidth中定义 . ”

Tkinter: How to get frame in canvas window to expand to the size of the canvas?

如果我修改了函数调用和函数，那么我得到错误“TypeError：FrameWidth（）缺少1个必需的位置参数：'canvas'”修改是

canvas.bind('<Configure>', self.FrameWidth(canvas))

def FrameWidth(self, event, canvas):

问题＃2（之前发布，但没有帮助）

我也看了这个问题：

Python Tkinter Scrollbar Shaky Scrolling

但是这个问题正在解决一个不规则行为的滚动条 .

问题＃3（之前发布，但没有帮助）

我也看过这些问题并加权= 1，但这没有帮助：

Python TKinter: frame and canvas will expand horizontally, but not vertically, when window is resized

任何意见，将不胜感激 .

这是我的MWE：
