Return

i new java , in our code using gwt. we using keypressevent process key_enter request. seems, each enter request, 2 events fired keypressevent . expect 1 event should fired, since enter 1 time. the following code. please check , let me know, need correct .. void onenter(keypressevent event) { if(event.getnativeevent().getkeycode() == keycodes.key_enter) { //(seems times code called) //domy stuff } } if use event.getcharcode() instead of event.getnativeevent().getkeycode() , returns 0. any idea how fix. thanks, i prefer using keyupevent because user can't distinguish keypressevent here solution: void onkeyup(keyupevent event) { if(event.getnativekeycode() == keycodes.key_enter) { // handle key press } }
