hi
i would like to know if it is possible to know if an active instance of a
view is running or not?
in fact i wrote a program that consist in 3 views that are refreshed by
another program. the problem is that when i close a view all the program
bugs.
also what i need is this :

each view when is launched register itself to the main program. if this
view is visible and is in accept mode the main program serves him
otherwise no.
i need also that even if the view is not visible that the data that the
main prog send to it have not to be lost.

to be more clear :
one of my views has a text area that display messages from an udp
connexion.
when the view is visible the message appears. but when i close the view
and reopen it there's no more messages displayed.

thanks....and sorry for my approximative english

I would structure your plugin to have a view-independent model object
representing the log of messages from the UDP connection. Then the view,
when created, would obtain the current list of messages from the model, and
would register itself as a listener for further entries in the model. When
closed, the view would unhook its listener in its dispose() method.
