I fiddled with this quite a bit a while back, and I just upgraded to 2.1 so I panicked when I read this. However, I just tested in Safari and Firefox (both on Mac) and everything still works.
The key, as Dominic mentioned, is to handle KEY_ENTER in a handler for KeyDownEvent instead of KeyPressEvent. Actually, I also just noticed that I'm not using event.getCharCode(). I'm using event.getNativeEvent().getKeyCode(). In fact, looking at the JavaDoc for KeyCode, it says, "Contains the native key codes ...", so that gives me some confidence that getting the key code from the native event is the way to go. I suspect that it's the combination of using KeyDownEvent and event.getNativeEvent().getKeyCode(). Character codes are probably more to represent printable characters. While you could consider a new line a printable character, the enter key doesn't translate to a new line in all input contexts. I suspect you're in one of those contexts (if you're trying to add some behavior for it), so it makes sense that you want the native event in this case instead of whatever character it would be interpreted as. -Brian On Fri, Dec 3, 2010 at 7:57 AM, aditya sanas <[email protected]>wrote: > hi dominic, > > > I m receiving key press event in all the browser the thing that i have > noticed which doesn't work in GWT 2.1 is - > > *if(event.getCharCode()==KeyCodes.KEY_ENTER){ * > > the o/p of event.getCharCode() in GWT 2.1 is nothing not even 0 so i cnt > compare it with KeyCodes.KEY_ENTER > > i had tried one more new method that has been introduced in GWT 2.1 which > getUnicodeCode() which gives 0 whenever i presses ENTER but this is not the > right because i m getting 0 even when i m pressing any arrow key. > > how to figure this out...? > > > -- > Aditya > > > > On Fri, Dec 3, 2010 at 5:46 PM, dominic jansen > <[email protected]>wrote: > >> hi aditya, >> >> i ve noticed that there are different behaviours for the >> KeyPressHandler for each browser (e.g. for me the safari browser did >> not recognize the keypressevent). >> >> maybe you can use the KeyDownHandler or KeyUpHandler instead of the >> KeyPressHandler. this worked for me.... >> >> best, dom >> >> >> >> 2010/12/3 Aditya <[email protected]>: >> > Hi, >> > >> > I have updated my GWT version to 2.1 and faced some of the problems >> > regarding textbox' key press handlers... >> > >> > the code which works completely fine in previous version is >> > >> > txtPassword.addKeyPressHandler(new >> > KeyPressHandler() { >> > @Override >> > public void onKeyPress(KeyPressEvent event) { >> > >> > >> if(event.getCharCode()==KeyCodes.KEY_ENTER){ >> > // some processing here to send >> > username password to server >> > } >> > // class closures. >> > >> > whenever user presses an ENTER key the code from 'if' condition gets >> > executed but this does nt work in GWT 2.1 >> > is there any other way to perform this validation to know user has >> > striked ENTER or not...? >> > >> > Thanks, >> > Aditya >> > >> > -- >> > You received this message because you are subscribed to the Google >> Groups "Google Web Toolkit" group. >> > To post to this group, send email to >> [email protected]. >> > To unsubscribe from this group, send email to >> [email protected]<google-web-toolkit%[email protected]> >> . >> > For more options, visit this group at >> http://groups.google.com/group/google-web-toolkit?hl=en. >> > >> > >> >> -- >> You received this message because you are subscribed to the Google Groups >> "Google Web Toolkit" group. >> To post to this group, send email to [email protected]. >> To unsubscribe from this group, send email to >> [email protected]<google-web-toolkit%[email protected]> >> . >> For more options, visit this group at >> http://groups.google.com/group/google-web-toolkit?hl=en. >> >> > -- > You received this message because you are subscribed to the Google Groups > "Google Web Toolkit" group. > To post to this group, send email to [email protected]. > To unsubscribe from this group, send email to > [email protected]<google-web-toolkit%[email protected]> > . > For more options, visit this group at > http://groups.google.com/group/google-web-toolkit?hl=en. > -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
