Listening to TextRange string

Hi everybody,

Is there a way to be notified when the content (the string,
I mean) of a 
TextRange is changed ?

I feel that the answer is negative, from some mails I've
read in this 
list, but in case there is a miracle...

TextRange publishes XPropertySet, which enables registration
of a 
property listener, but there is no such thing as a
'string' property (at 
least, documented).

Thank you if you know a trick on this,

Julien Galand

As far as I know there is no way to be notified when a
specific  
XTextRange is changed.

The PropertyChanged event is called for "bound"
properties and the  
PropertyVeto event is called for "constrained"
properties. The  
XPropertySet has as far as I know neither of them and so the
 
Listeners will never be called anyway.

If you are "just" after changes via UI you could
add a ModifyListener  
to your document and in case it is called you could get the 

ViewCursor and so have the currently changed TextRange.

Hope that helps
