在Tkinter中使用背景图像后，按钮放错了位置

如何解决在Tkinter中使用背景图像后，按钮放错了位置

每当我使用背景图像运行此代码时，按钮网格就会放错位置并推向底部。幸运的是，当不添加背景时，它可以按预期工作。我希望它们在执行时覆盖背景。供参考的图片添加如下。非常感谢您的帮助。

第一个图像是错误。第二张图片是必需的输出。 注意：我仍然是Python和Tkinter的初学者，因此各种术语和方法可能超出我的范围。如果考虑在内，将不胜感激。

如果需要，您可能会知道这是一个tkinter项目，用于从A * A网格中拾取奇数一张图像。

解决方法

我自己得到了答案，因此可以共享以供将来使用。

C = Canvas(root,bg="blue",height=250,width=300)

此部分绘制250 * 300尺寸的画布，因此不允许按钮在其上绘制。

只需将其更改为

C = Canvas(root,height=0,width=0)

获得理想的结果
