Ever wonder how you could create an Alert control but make the text be non-selectable (without subclassing the Alert control, that is)? Well, here’s how.
By using the hidden powers of the “mx_internal” namespace, you can access the Alert control’s internal alertForm property (an AlertForm object — for more information see the AlertForm.as class in the mx.controls.alertClasses package) and from there modify the internal textField property (a UITextField object), and set the selectable property to false.
Taa-daa! Non-selectable text.
