Hi,

I have a custom editor extending a TextEditor, and managing structured data above what is manipulated by the user in the text editor area.
E.G. when the user enters the text $a_local_code$ , my editor already enables the user to trigger a dialog providing an editable form for manipulating the structured data associated with a_local_code.

So far, this works great.

What I want now is the ability to make the structured data associated with the text $a_local_code$ "follow" the text during copy|cut / paste operations.
I would like to be able to participate in these operations, by adding, along with the usual TextTransfer and RTFTransfer contents, my own Transfer type for adding a more structured "view" of what is
copied/cut.

By looking at the StyledText widget, I can't imagine a way to do that, so I'm asking here: how and where could I plug my code ?

Currently, I'm thinking about something along those lines: find a way to be notified right after the copy/cut/paste operation occurs, and take that opportunity to 1. get the current types and contents
from the Clipboard, 2. create my additional related transfer content if relevant 3. set the content of the clipboard with the old content plus my additional content.

Is there a non hackish way of doing this, if at all ?

Thanks in advance,
