Description Jan Jancura 2001-12-03 13:49:26 UTC
We (debugger) need to add some annotations to newly opened editor pane. But
there is no way how to listen on editor pane open / close. See property:

So we must add all existing annotations during startup of IDE. Thats really bad
for startup performance. Do you know some beter workarround?
Can it be fixed for NB3.3.1?
Comment 1 _ ttran 2001-12-03 13:57:22 UTC
Jan, it's really bad that you start filing such kind of bugs that late
in release cycle.  It's even worse that it requests API changes.

No way we will do it for NB 3.3.x
Comment 2 Jan Jancura 2001-12-03 14:54:04 UTC
Why is it bad to file some bug during feature freeze? Do we have some
bugfreeze? ;-)

Ou, sorry I understand.
But our original bug is one weak old, so I added bug to core as soon
as I investigated the problem. Its up on you when it will be fixed and
if its RFE or bug. But I think that you agree that its good to have it
in issuezilla as soon as possible.
Comment 3 Peter Zavadsky 2001-12-03 15:33:20 UTC
I think there is a way:
You should listen on TopComponent.Registry, i.e. particulary on
PROP_OPENED event fired and in that case retrieve what you need.
Eithre directly TC's from Registry.getActivated or getOpened methods, or
from getActivatedNodes and retrieve the editor cookie accordingly.

The rest what you need should maintain in your module.

CC Yarda, who knows much more about it, maybe he knows better solution.
If there should be the API changed later? Passing the question to
Yarda too.

Peter, you are right, this is a solution. Hanz, if you can build your
code around what Peter suggested, but separate it somehow so when
something better will be implemented you will not have problems to
change your implementation.
Comment 5 Jan Jancura 2001-12-04 09:27:00 UTC
I will try it.
Comment 6 Peter Zavadsky 2002-01-29 09:54:38 UTC
Eval.: The need is to have a possibility to get LineCookie (for
setting annotations), from opened/closed editor.

Currently TopComponent.Regitsry fires a PROP_OPENED prop change where
is possible to retrieve the TC's which were and are opened, thus which
are closed as well. But there is no nice way to get Node (DataObject)
which belong to the TC, thus not nice way to get LineCookie etc.

The solution probably will imply an API change. So there is needed to
discuss it, whether it is enough to make some possiblity to get from
TC to which node (dataobject) belongs if there is such. Moreover if
this is suffiecient for solving of this issue. (e.g. whether there
should be also fired a something like "PROP_CLOSED", saving the
necessary extraction from PROP_OPENED old/new values... or some other
Comment 7 Jaroslav Tulach 2002-01-29 12:30:37 UTC
TopComponent.getActivatedNodes ()[i].getCookie (DataObject.class) will
give you the top component.
Comment 8 Peter Zavadsky 2002-01-29 16:45:03 UTC
As I understood Hans the right way, he needs to take actions when TC's
are opened and closed, i.e. it isn't enough for him to listen just on
activated nodes, but rather on PROP_OPENED. And then somehow get the
related nodes(dataObjects) to the just opened/closed TC's, to do his work.
Comment 9 Jaroslav Tulach 2002-01-30 09:07:28 UTC
What is what I am talking about: Find the opened component and then
do: tc.getActivatedNodes ()[i].getCookie (DataObject.class) on the

I guess he is missing method like getOpenedNodes() (?? well sounds
