Question

这不是实际的代码，我删除了许多项目只是为了分享完整的代码来重现问题。以下是重现问题的步骤。

选中/取消选中启用配置文件图像复选框。（启用或禁用工作正常）
单击“设置”按钮并重试取消选中复选框以从 Canvas 隐藏项目。这次它只是删除了图片而不是画布上的所有项目。当有人取消选中复选框时，我希望一切都消失。

这里的问题是，当第一次在 init 中加载设置功能时，它工作得很好，但是如果您单击任何其他按钮并再次返回设置以隐藏画布项目，它只是隐藏图像而不是画布上的其他两个项目。

app = AppLayout(path,'red','green')

app.mainloop()

grid_forget 或 grid_remove 不会隐藏画布上的所有小部件
