我试图在tkinter上做一个可调整大小的可滚动画布框架。
问题出在第一次迭代中。我构建了一个窗口和一个画布，并将事件绑定到"<Configure>"，以将其大小扩展到窗口的大小。
我创建了一个Frame，然后使用create_window将其放入画布，但是由于某种原因，该方法的参数无法正常工作，或者我不知道它是如何工作的。
我给它的尺寸为200 x 200，并带有height和width参数，框架显示为100x100。 这是因为未在x = 0，y = 0处显示该框架，而是在此下方显示。我已将其位置指定为0,0。
我现在不知道为什么会遇到这个问题，但是它使我发疯，如果有人可以帮助我，我就把代码留在这里。

我找到了一种使用画布制作我的响应式可滚动框架而没有定位问题的方法。
我从垂直滚动框架的git页面中获取了代码。因此，感谢Eugene Bakin做到了这一点。 https://gist.github.com/EugeneBakin/76c8f9bcec5b390e45df
因此，请对该代码段进行一些修改以适应我的必需品。
这是我的Scrollable Resizable Tkinter Frame的代码。
