protecting regions of java code from editing [message #181341]

Hi

how could I prevent some "parts" of a java source from being
edited/changed while leaving the rest of the file normally editable ??

TIA,
Edo

PS - I had defining a custom annotation and a custom marker,
and then lattaching listsners to the sourceviewer to set doit=false to
verify events.
this only stops some typing in the java editor, while other actions (eg
text move/up and down) are still doable and "screw" the source.

So I am looking at some "veto" coming frm the Document or ... the Java
Model/Java DOM/AST ?

Tom,

(don't know how to get to that thread using the hyperlink you posted,
anyway)
that was a thread I started some time ago and I thank you for your answer.

The problem I have is that there are lots of "actions" (*)
that do not fire VerifyEvent event and so I can't block them.

I must also worry about refactorings - as my source would be changed
even if there is no editor open on it!!

this is why I am tring to block these changes at a different level.

any ideas (from anyone in the community) ?

Edo

(*)e.g. cut (this may be a bug I submitted in bugzilla),
move selected lines up/down etc
refactorings!

That is why I suggested blocking the events from inside a custom
document, which is the model behind what you see in the editor and
receives all changes, including refactorings and others that operate
directly on the document.

The problem with this is that there is no veto-mechanism similar to the
one offered by VerifyEvent - I am afraid there is currently no easy
solution for this.
