Catching Keyboard events

Hi All,

How do you catch keyboard events going to a specific control on a form?
What I want to do is catch the Insert key when a listview has the current
focus. I've had a scout round but nothing seems obvious. I've tried "wiring  
up" the #keyTyped event but nothing happens. The only other clue I've got
is to either su-class the ListView view or presenter, but this seems like
overkill. Any clues would be appreciated.

Cheers

Try catching the #keyPressed: event (instead of #keyTyped).  Something like
the following:

    listViewPresenter
        when: #keyPressed:
        send: onKeyPressedInList:
        to: self.

Hi Chris,

Thanks for the suggestion, but it dosen't work. Nothing happens. I even
placed a self halt in the event handling method and it doesn't even get
there. I think this was one of the things I tried before I posted my
original message as this is how I would of expected it work too.

Regards

Barry

Are you sure you've typed the #keyPressed: event name correctly (including
the colon at the end). Try this:

lp := ListPresenter show.
lp when: #keyPressed: send: #beep to: Sound.

Set focus to the list presenter and hit the Insert key. You should hear a
beep.

Cheers Andy!

The colon on the end of #keyPressed: was the missing ingredient!
