Re: Trigger button on ENTER inside a TextBox?

2013-03-14 Thread Kody 
Thanks Jens. Yes I use uibinder, did not know I can register more than one
widget to the same handler method. Will go for this approach.

 sure you must add keyListener for all TextBox .
 But if you create one method,it 's smart.

 example for

 private void addListeners(ListTextBox textboxs ,Listener listener){
 for(int i=0;itextboxs.size;i++){
  textboxs.get(i).addKeyListener(listener);
 }
 }

 Hi,

 I have a popup with a bunch of TextBox and TextArea fields. Also 3 Buttons
 like Save, Cancel, Reset.
 For the TextBoxes I would like to trigger the Save action if ENTER is
 hit while inside a TextBox (not for the TextAreas).

 Would I have to register a KeyDownHandler for all the TextBoxes (which
 would be lots of boilerplate code)? Or is there anything native in GWT
 catching ENTER key in TextBoxes?

Re: Trigger button on ENTER inside a TextBox?

2013-03-13 Thread Jens 
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.
