Do you use UiBinder for the DialogBox content widget? If so you can add
more than one widget to @UiHandler:
@UiHandler({"box1", "box2", "box3"})
void maybeTriggerSave(KeyUpEvent event) {
//check for ENTER and trigger save
}
Without UiBinder the above is equivalent to:
KeyUpHandler maybeTriggerSaveOnKeyUp = new KeyUpHanlder() { ...... };
box1.addKeyUpHandler(maybeTriggerSaveOnKeyUp);
box2.addKeyUpHandler(...)
....
If you instantiate the TextBoxes yourself you could replace "new TextBox()"
with "createTextBox()" and add the key handler inside that method.
Alternatively you could listen for Key events on your content widget
(addDomHandler()) of your DialogBox and then figure out if the event source
was a TextBox and not a TextArea.
