actionscript 3 - Add MXML event listener on component's child -


i'm not sure if possble, add event listener on sub component mxml. this:

my component

<s:group>     <s:button id="mybtn" label="click me" /> </s:group>

main application

<local:mycomponent>     <local:mybtn click="dosomething()" /> </local:mycomponent>

i know can in code, want know if it's possible in mxml. if it's possible, correct syntax?

it possible, requires lot of setup.

first add event metadata mycomponent:

<s:group>   <fx:metadata>         [event(name="click", type="flash.events.mouseevent")]   </fx:metadata>     <s:button id="mybtn" label="click me" /> </s:group>

in theory should make sure component dispatches click event; since click bubble default not need else event.

now, main component show event in mxml code hinting, , compiler not complain:

<local:mycomponent click="dosomething()> </local:mycomponent>

generally, not recommend trying drill down component in order place listeners on events dispatched component's children. break of encapsulation. parent component should not know implementation details of children.
