I have found some unexpected behaviour with the storing of form data.

I have two forms, the second form is shown from the first one (just a

I have looked on how to solve the problem, but I'm not really good in
this, hence my question. I would like to expand the
TFormPropertyStorage >> class, so data is stored on destroy (or should it
be free). Proposed >> changes are;

- add a fhtDestroy to TFormHandlerType
- add a AddHandlerDestroy to TCustomForm
- add a destroy handler in TFormPropertyStorage.Create
- add a destroy method in TFormPropertyStorage

Have I forgotten anything, or am I on the wrong track?

I'm not sure that handling it in the ondestroy event is a good idea: it
may be 'too late' at that time.

Correct.
Maybe instead TFormPropertyStorage should save, when the
Application.MainForm is closed.

What do you do with other forms then ? I create my forms dynamically,
and they should have their stuff saved when they are closed, because
right after that, they are destroyed.

I meant instead of saving on destroy.
The Storage must be saved on Closing a form _and_ closing all forms (=close
mainform).
Maybe when the application shuts down, all open forms should trigger an
OnClose?

This is not Delphi compatible, so I would advise against it...
(I tested a delphi app: secondary forms do not get an onclose.
They are simply destroyed.

Michael.
