Another problem I found.
The documents inside the frames are not closed properly.
Should I do smth like this :
doc = xFrame.getComponent()
doc.close()
everytime I close a frame?
I think I have a problem with understanding which components
are disposed when the container they belong to is disposed
and which aren't.
One frame knows one controller and one controller knows one model.
But one model knows several controllers, and each of these controller
object referr to one frame.
It's designed using the Model-Controller-View paradigm.
a) closing the frame
If you close the frame it disposes the controller.
And the controller will deregister itself from the model.
If this disposed controller was the last one, the model will be closed
too ... otherwise the model will stay alive - because its referenced by
other freme/controller pairs.
b) closing the model
If you close the model it iterates over all registered controller.
There it asks for the assigned frame and close it.
This will reuse the mechanism of a) !
As you can see: nothing will stay alive if you close one of these
resources. (Excepting if you try to close one controller explicitly by
calling dispose() there ... That's not allowed and will make trouble.
It's defined, that the frame is the owner of the controller and it's not
allowed to close the controller directly.)
Cheers,
Andrzej.
