    text
    copied!<p>I would like to change a behavior of SuggestBox in GWT. I want submit value by pressing ENTER. However the SuggestBox have a KeyHandler, which catches any enter key and sets a new Selection. I am looking for a solution to remove/overide this Handler.</p> <p>This method is called by constructor in SuggestBox</p> <pre><code>private void addEventsToTextBox() { class TextBoxEvents extends HandlesAllKeyEvents implements ValueChangeHandler&lt;String&gt; { public void onKeyDown(KeyDownEvent event) { switch (event.getNativeKeyCode()) { case KeyCodes.KEY_DOWN: display.moveSelectionDown(); break; case KeyCodes.KEY_UP: display.moveSelectionUp(); break; case KeyCodes.KEY_ENTER: case KeyCodes.KEY_TAB: Suggestion suggestion = display.getCurrentSelection(); if (suggestion == null) { display.hideSuggestions(); } else { setNewSelection(suggestion); } break; } delegateEvent(SuggestBox.this, event); } public void onKeyPress(KeyPressEvent event) { delegateEvent(SuggestBox.this, event); } public void onKeyUp(KeyUpEvent event) { // After every user key input, refresh the popup's suggestions. refreshSuggestions(); delegateEvent(SuggestBox.this, event); } public void onValueChange(ValueChangeEvent&lt;String&gt; event) { delegateEvent(SuggestBox.this, event); } } TextBoxEvents events = new TextBoxEvents(); events.addKeyHandlersTo(box); box.addValueChangeHandler(events); </code></pre> <p>}</p> <p>Is it possible to remove this Handler from box by using HandlerRegistration? Is there any nice solution by extending class and overriding private method?</p>
