object --+ | util.EventObject --+ | ui.component.Event --+ | TextChangeEvent
TextChangeEvents are fired when the user is editing the text content of a field. Most commonly text change events are triggered by typing text with keyboard, but e.g. pasting content from clip board to a text field also triggers an event.
TextChangeEvents differ from ValueChangeEvent
s so that they are triggered
repeatedly while the end user is filling the field. ValueChangeEvents are
not fired until the user for example hits enter or focuses another field.
Also note the difference that TextChangeEvents are only fired if the
change is triggered from the user, while ValueChangeEvents are also fired
if the field value is set by the application code.
The ITextChangeNotifiers implementation may decide when exactly TextChangeEvents are fired. TextChangeEvents are not necessary fire for example on each key press, but buffered with a small delay. The TextField component supports different modes for triggering TextChangeEvents.
