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();
}
{
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.";
}
}
{
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
