StyleRange Persistence [message #1701425]

I am using the StyledText widget in my application. I persist the text string in a database, but I also need to persist the formatting (i.e., the StyleRange data). Using myStyleRange.writeObject() would seem to suffice, but StyleRange is not serializable. So, how do I go about doing this?

StyledText doesn't support any way of serializing information like that out of the box: it's flexible in allowing arbitrary objects (including SWT controls) that there's no format to store a perfect representation. From what I've seen, apps that use StyledText maintain a parallel model that is used to update the StyledText, and the app serializes out their model instead.

That said, StyledText can serialize out to RTF via the clipboard (RTFTransfer). The representation will be imperfect if you have controls or images, and it overwrites the clipboard contents (though you could try to save and then restore the clipboard).

Okay, thanks. It looks like I'll just have to roll my own!
