ActionScript Language Reference

Once the required objects and constants have been defined according to the MASCA API, a

component depicts interface interaction in accessible terms via sendEvent(). For example,

the setLabel() method of the radio button component uses sendEvent() to notify a screen

reader when the button’s label changes:

FRadioButtonClass.prototype.setLabel = function(label)

{

this.fLabel_mc.setLabel( label );

this.txtFormat();

// ACCESSIBILITY

if(Accessibility.isActive()){

Accessibility.sendEvent( this, 0, this.EVENT_OBJECT_NAMECHANGE );

}

}
