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. I use this 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. In
this way I handle both ENTER, ESC and the pusbuttons the same way
without having to listen to any keystrokes etc.
Now to my question, I was thinking of vetoing the close if the values in
controls in the dialog are not correct. But I cannot determine if it is
ENTER, ESCAPE or the pushbuttons that caused the "close" in the "veto"
method in the listener. I need to know that because if
Cancel-pushbutton or ESC was pressed I will never veto the close.
Hmm i'm a little unstructured here, but how do you go about doing this
i.e. handling the keyboard ENTER, ESC as well as pushbuttons that does
the same functionality ? Am I going about this in the wrong way, i.e.
how to handle ENTER, ESC to make them perform the same
Thanks for any help,
Tomas
