[我正在使用 python Tkinter 及其与 sqlite3 的数据库连接。我能够将我的整个代码保存在数据库中，但我不知道如何在 canvas 下获取绘图并将其保存在我的数据库中。 我还希望当我在数据库中搜索我的其他数据时，与之相关的绘图也将在 canvas 上获取。]
这是此处输入链接描述的可能副本。 和你的有一点不同，你想把它保存到 sqlite。 在这种情况下，PIL 以字节为单位存储图像数据。 然后您可以将其存储在 varchar 或 blob 中的 sqlite 中。
使用 sqlite3 和 tkinter 我做了这个小型库存管理系统，问题是数据库的条目总是 null
[英]Using sqlite3 and tkinter i have made this small inventory management system, the problem is the entry to the database is always null
