Apache Royale : How to detect enter key on j:textInput

Question

I have this code :

<j:TextInput localId="ti_pass"  >
    <j:beads><j:PasswordInput/></j:beads>
</j:TextInput>

Unfortunaly looking at https://apache.github.io/royale-docs/component-sets/jewel/textinput I didn't find a bead for KeyDown event. Is there a specific event to listen for it ?

Is there a way to know if enter key has been hit ?

Thanks Regards

Answer 1

I must say that there's a better solution to your problem, but I completely forgot due to focus on keydown. Sorry.

You have an enter event in TextInput that you can use directly. Example is in Tour De Jewel in TextInputPlayGround.

private function enterPress(event:Event):void
{
    trace("enter pressed");
}

<j:TextInput text="A TextInput" enter="enterPress(event)"/>

you need to listen for KeyboardEvent.KEY_DOWN on the strand (TextInput).

If you are in MXML, first add a listener for initComplete in the surrounding container for listenKeyDown:

initComplete="listenKeyDown()"

Then in the Script part add:

public function listenKeyDown():void {
    the_textinput.addEventListener(KeyboardEvent.KEY_DOWN, keyDownEventHandler)
}

protected function keyDownEventHandler(event:KeyboardEvent):void
{
    trace("Any key:", event.key);

    if(event.key === KeyboardEvent.KEYCODE__DOWN)
    {
        trace("Down key:", event.key);
    }
}
