Re: [ jEdit-devel ] How to tell if a message is meant for me

[Colin C. <co...@ex...>]

I understand about loose coupling and not wanting to know who the receiver is 
but I would have thought part of this should be some way for me to determine 
if this message effects me.

For example, on the properties page; I seem to be getting a updated 
properties notification whenever any properties are changed for any plug in. 

The same for Dockable window; whenever a new plugin dockable window is 
created I seem to be receiving a message; shouldn't this only be a new 
Dockable window associated with my Plug in is created ? 

Thanks, Colin
