Undo after save. How?

Martian · Post by **Martian** » Thu Apr 28, 2016 8:40 pm

In my app I always save document when user switches to another app or minimize.
It's very uncomfortable to lose undo after save.
So how to do it in TRichViewEdit?

TRichViewEdit does not lose undo after save.

Hm. But for some reason my undo button became inactive after save. Gonna check my code then.

I found the reason why I lose undo every time I save my document.
It's because of

Code: Select all

RichViewEdit1.DeleteUnusedStyles(True,True,True);

I wrote this code several years ago and maybe it's not really necessary in the latest versions of RVE?

This code still may reduce the file size.
But it still clears undo buffer.
So I recommend to call it on loading instead of on saving.
