KeyEvent management differs depending browser [message #766084]

Hi,

after creating a check button , and adding a keyListener on this one, i don't have the same behaviour when hitting the return key when the button has the focus:

on Opera and Firefox :
- the methods keyPressed and keyReleased of the listener are called

on IE, Chrome, and Safari :
- None of these methods are called.

Note : when hitting alpha numeric caracters, the keyEvent is sent.

How can i do for sending the return key keyEvent ?

Thanks,
Bertram

Hi Bertram,
what is the use case of adding a key listener to the check button? If you want to be notified when check button is selected, use selection listener. The check button changes its state (selected/deselected) by using ENTER or SPACE.
Best,
Ivan

Hi Yvan,

thanks for the quick reply.

I've got a login dialog with a composite containing :
- a button for connection
- a group with
- a text login
- a text password
- a check buton for administrator

with the tab navigation when i focus the check button, and with the space button i can can change the selection of the check button. without focusing the connection button, i want to select the connection button when hitting the return key.

so waht i do was : add a keylistener on the check button, and if the keycode is equal to SWT.CR, i send a selection Event on the connction button.

This works on FF and opera, but not in IE , Safari and Chrome.

Can you tell me what is the correct behaviour ?

If there is no solution, i will change the check button by a combo box.

Thanks
Bertram

Hi Bertram,
the current implementation of key events has some drawbacks. We have plans to address them soon. Please file a bugzilla [1] about this cross-browser inconsistency.
