Here's what I've got... I have an 'if' statement that calls a boolean function
-- problem is, that function pops up a Yes/No Alert window. In order to know
what button the user clicked, the handler-function must be called from the
Alert pop-up, thereby preventing the boolean function from returning a proper
value based on the outcome of the Alert window...
Lemme 'splain a bit better with an example:
private myMainFunction():void {
//many things going on here before we get to the 'if' statement below.
if (myBooleanFunction()) {
//set a local-to-this-function variable here.
} else {
//set a local-to-this-function variable to something else.
}
//More things going on here that need the above-referenced
local-to-this-function variable to be set before they can run.
}
private function myBooleanFunction():Boolean {
Alert.show("Do you want to do this?","Alert...",(Alert.YES | Alert.NO, this,
alertHandler, null, Alert.NO);
//Flex is expecting a true/false return HERE, but I can't give one because I
don't know the result until the alertHandler has run.
}
private function alertHandler(event:CloseEvent):void{
if (event.detail == Alert.YES) {
return true; //of course alertHandler isn't a boolean, so this doesn't
work.
} else {
return false; //of course alertHandler isn't a boolean, so this doesn't
work.
}
Of course the above example does NOT work, because the alertHandler function is
of type void, and the myBooleanFunction doesn't return anything. So, how do I
get the myBooleanFunction to return true/false based on the outcome of the
alertHandler function? Is there any way to do this? If not, what's my
alternative? Is there a way to stop the program's running until alertHandler
sets a public variable, perhaps? What's the proper way to handle this?
