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 . ”

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('', 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：

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：

任何意见，将不胜感激 .

这是我的MWE：
