Hello,

I created a new morph with several buttons to be used as the man machine
interface.
This morph use a file to log events and operator actions.

The morph is created with "new openInWorld"

How do I destroy my morph properly ?
I know I can use the delete message, but how to tell my morph to log a last
message and to close the log file before quitting ?
I can also create a quit button and create a method to do the job, but in
case of the operator use the pink Halo (move to trash) how to call a
cleaning method automatically ?
Looking around I found the "release" method.  Do I need to create one ?
When is this method called ?
I created a release method, but it isn't called when I use the pink halo.

I use Squeak 3.6 .

Thanks

Joseph
