Re: How do you call JS oninput event from a GWT textfield

Hi Jen,

Thank you for responding.

I have tried the ChangeHandler and doesn't do what the use case needs. 

I have tried implementing addBitlessDomHandler but I can't quite get it to work either.

Looking over what i wrote I wasn't specific on the behavior.  The button will be disabled until the user begins to type in the textbox.  I have found when you drag n drop text in to the textbox the button doesn't enable until you do a key down or key up action.  I have also found cutting text from the textbox with the mouse the button does not disable.

Thank you,

You can define your own InputEvent + InputHandler and then use textBox.addBitlessDomHandler(new InputHandler() { ... }, InputEvent.TYPE).

To see how you would implement an InputEvent you can take a look at existing DOM Events like com.google.gwt.event.dom.client.ChangeEvent / com.google.gwt.event.dom.client.ChangeHandler.
