How to display an Alert synchronously ?

Question

The Alert.show() function displays an alert asynchronously in
Flex (the code line which follows the Alert.show() statement is
executed well before the alert actually appears on screen).
Anybody knows a way to force this alert to show itself
syncronously instead please?
Thank you in advance.

Answer 1

In the following example an Alert box is popped up with a
Yes/No question. At no time is the Flash Player (your Flex SWF)
paused or waiting. This is purely event driven.
private function showChoiceAlert() : void
Alert.show("This is a choice. Either pick Yes or No,
please", "Choices",
Alert.YES | Alert.NO, null,
alertHandler);
You call this function as the result of some action, such as
a button click. When either of the Alert's Yes or No buttons are
picked, the function, alertHandler(), is called:
private function alertHandler( event:mx.events.CloseEvent ) :
void
// the event.detail indicates which button was pressed.
Compare it
// to the static values in the Alert class.
if( event.detail == Alert.YES ) {
result.text = "You picked Yes";
} else if( event.detail == Alert.NO ) {
result.text = "You picked No";
} else {
result.text = "I don't know what you picked!";
In this example, the alertHandler fills a Label component's
text property.
In other words, you cannot 'wait' for the user to do
something. The 'waiting' is simply the Flash Player doing whatever
it does until the user picks a button on the Alert dialog which
fires an event.
