Actionscript/Flex 3 - Passing information from popup title window to main app

Asked by: jrwalker2

I am having a problem getting information back from a popup title window to the main app. During debugging, I was able to see that the value was set in the custom popup but it doesnt get back to the main app. Can you please help? Am I missing something? Thanks

//From the main app
private function setDefaults():void
{
             var pop1:StuffWindow = StuffWindow(PopUpManager.createPopUp(this, StuffWindow, true));
            
            // Set properties of the ArrayEntryFormEvents custom control.
            PopUpManager.centerPopUp(pop1);
            
            int var myStuff:int = pop1.stuff;
            
}
 
 
 
 
 
 
//Title Window for popup
<?xml version="1.0" encoding="utf-8"?>
<mx:TitleWindow xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" width="304" height="274" showCloseButton="true" borderAlpha="1" title="Stuff Window" close="removeMe()">

				//Closes the popup window
				removeMe();
				
			}
			
			//Cancel button click event listener.
	        private function removeMe():void 
	        {
	            PopUpManager.removePopUp(this);
	        }

int var myStuff:int = pop1.stuff;
you gotta call this upon window close so you get the value updated. also put that info in a variable outside the scope of the function so its available

by: julianopolitoPosted on 2008-04-05 at 06:33:05ID: 21288112

also, do not precede ther var with int. it should be only var myStuff:int = pop1.stuff;
I'm taking a deeper look into your code now, I was about to sleep when first answered.

by: julianopolitoPosted on 2008-04-05 at 06:37:11ID: 21288140

using your StuffWindow component , i did this example and it shows the stuff property correctly.

Is this what you want or, you wanted the inverse, to send a value to the window? Also if you wanted to bound the stuff var to the nummeric stepper,

Sorry for the late response julianopolito...I just woke up. This is what I am looking for, but whenever I tried to access the stuff variable outside of the setDefaults() method in the main app, it was always getting the initial value and not the new value (the updated numeric stepper value). It seemed to be reset back to the initialized value. For instance, I placed a button in the main app and set its click event to call results(). In results, I try to get the updated stuff value (after the changing the value in the numeric stepper and pressing OK), but I get the old value of 30.

But...I just realized why. The popup window instance only had scope to the setDefaults() method. When I gave it scope to the entire class, I was then able to access the latest stuff variable (after a change to the numeric stepper). Thanks

yes, that's what i told you in my first post. you should scope the variable to the application. also you should bind stuff to the numericstepper. there was no need to keep reference to the window though, if you keep the myStuff variable as an application property.

by: jrwalker2Posted on 2008-04-05 at 20:51:32ID: 21290620

I discovered that if you use event listeners to listen to the button clicks of the popup from within the main app, you have more control of the value that's set in the popup and it seems to sync the changing values up nicely. Thanks
