Question

Buttons in flex can be pressed with the space key, but a client would like to press enter instead of space. This can be achieved by programming each button, but it would be very time consuming.

Does anyone have an idea how to do this in the less amount of time?

thanks.

Answer 1

I created a KeyPressForwarder that “forwards” the key press as a click:

package com.sophware.backend
{
    import flash.events.IEventDispatcher;
    import flash.events.KeyboardEvent;
    import flash.events.MouseEvent;
    import flash.ui.Keyboard;

    public class KeyPressForwarder
    {   

        public function dispatchAsClickEvent(evt:KeyboardEvent):void
        {       
            if(evt.keyCode == Keyboard.ENTER)
            {           
                var dispatcher:IEventDispatcher = evt.target as IEventDispatcher;
                dispatcher.dispatchEvent(new MouseEvent(MouseEvent.CLICK));
            }           
        }       

    }   
}

And then setup a binding:

<mx:Button
    id="Name"
    keyUp="_keyPressForwarder.dispatchAsClickEvent(event)"
    click="addOrModifyEntry(event)"
    />

You could eliminate the class and just use the function as the concept is generic. Just make sure you have a click handler to handle the forwarded event.
