Hi,
I'm after a design/code pattern for handling ENTER and ESC for dialogs
(modal) as well as PushButtons performing the same function. When I
press ENTER or ESC the dialog is closed and I can find out in the
DialogStateListener which one was pressed (true,false) which I guess is
the default behaviour of pivot. There I can get the dialog result to see
if I should "commit" or "rollback" the changes in the dialog or not ( I
use Cayenne ORM). I also have pushbuttons in the dialog that will yield
the same functionality, i.e. close the dialog and send a true/false result.
Now to my question, I was thinking of vetoing the close if the dialog
values are not correct, but I cannot determine if it is ENTER, ESCAPE or
the pushbuttons that caused the "close". I need to know that because if
Cancel or ESC was pressed I will never veto the close.
Hmm a little unstructured there, but how do you go about doing this i.e.
handling the keyboard ENTER, ESC as well as pushbuttons that does the
same functionality ?
Thanks for any help,
Tomas
