@short declaration of special continuation for filter selection
|
|
@descr Sometimes filter detection during loading document failed. Then we need a possibility
|
|
to ask user for his decision. These continuation transport selected filter by user to
|
|
code user of interaction.
|
|
|
|
@attention This implementation could be used one times only. We don't support a resetable continuation yet!
|
|
Why? Normaly interaction should show a filter selection dialog and ask user for his decision.
|
|
He can select any filter - then instances of these class will be called by handler ... or user
|
|
close dialog without any selection. Then another continuation should be slected by handler to
|
|
abort continuations ... Retrying isn't very useful here ... I think.
