RE: [flexcoders] Proper login window handling?

What you describe sounds like it should work.  If you suspect scoping issues, you are probably correct.  Use delegate() to make sure the handler function executing the viewstack.selectedIndex =  n call knows about the viewstack.

Subject: [flexcoders] Proper login window handling?

 

Hello,

 

I've build a LoginWindow.mxml consisting of a <mx:TitleWindow ...> tag and related code.  I call this from my main application as such:

 

  function show_login():Void
  {
   var parent = this;
   var isModal:Boolean = true;
   var initObj = {};
   var login = PopUpManager.createPopUp(parent, LoginWindow, isModal, initObj);
   login.parentObject = this;  // store a reference to this Application
   login.centerPopUp();
  }

So far so good.  When the user wants to login, I call a remote object with the username and password supplied by the user which queries a database and passes the return value to a loginResult function:

 

  function loginResult(result):Void
  {
   if (result == true)
   {
    // switch to a different panel in the stack
    //
    parentObject.main_stack.selectedChild = parentObject.login_ok_panel;
    this.deletePopUp();
   }
   
   else
   {
    login_result.text = "Sorry, your login details are incorrect.";
   }
  }

And this works fine, but it seems like a hack. I originally wanted to get this to work with events.  I setup an event handler on the "login" variable, the LoginWindow fires off an event if the login is successful, and the application handles the event and switches to a different panel in the stack.  The problem is, this didn't work.  I could display an alert dialog, but the call to switch the stack didn't execute.  I assume this has something to do with how it's being references (eg: event handlers are outside of the scope of the code in which they're created) but after an hour of fiddling with broadcast handlers and various other mechanisms, I couldn't seem to get main_stack to update.

 

Is this the only way to do it, is the event model cleaner, or is there a better methodology for displaying modal dialogs like a login screen?  Any pointers would be appreciated.

 

Thanks,

 

Blake
