PyQt 绘制自定义日期格式
我正在使用sqlmodel在qtableview中显示来自sql服务器的一些信息。
我设置了一个自定义的代理来处理数据的编辑。
我希望在表格首次加载时,日期能以特定的格式显示,现在日期显示成这样:
20011-04-30
但是当我编辑日期并点击单元格外部以确认后,日期就变成了:
30/04/2011
这就是它在数据库中存储的格式,也是我希望一开始就显示的格式。我不知道为什么编辑后格式会改变。
我猜我需要重新实现那一列的绘制方法,我之前在进度条上做过类似的事情,但我不知道如何处理文本。
这是我目前的代理代码,注意它为其他列设置了一些编辑器,但我主要的问题只涉及如何正确显示日期。

谢谢,汤姆。

为什么editor.setDisplayFormat("yyyy/MM/dd")这行代码被注释掉了呢?难道这不是应该负责格式化的吗?
