PyQt Paint自定义日期格式

Question

我正在使用sqlmodel在qtableview中显示来自sql server的一些信息。

我已经设置了一个自定义委托来处理数据的编辑。

我想在一个特定的格式来显示我的日期，当他们表第一次加载日期显示为这样： 20011-04-30 但是，当我修改的日期和点击关闭单元的接受日期则显示像： 30/04/2011 这是如何将其存储在数据库中，我希望如何显示它开始，我不知道为什么它编辑后更改格式。

我猜我必须重新实现该列的paint方法我已经做了一些类似的进度条，但我不知道如何去做文本。

这是我的代表，因为它代表着，注意是有一些编辑器设置为其他列，但我的主要问题只涉及如何正确显示日期。

为什么editor.setDisplayFormat（“yyyy/MM/dd”）被注释掉了？不应该照顾格式？
