Cool! In my case I was looking for an extensible framework that would
allow any of my views that get plugged into a tab to contain the logic
that determines whether they can currently be tabbed away from or not.
If you don't need anything quite so elaborate, it looks like the
solution you are using will do the job.

Thanks for that suggestion.
I was able to cancel the TabNavigator change by doing the following:
In my main app (where the TabNavigator is contained) in the
creationComplete event, I add a listener:
myTabNavigator.addEventListener
(MouseEvent.CLICK,handleTabNavigatorClick,true);
Then within that click event I call:
event.stopImmediatePropagation();
event.stopPropagation();
event.preventDefault();

When I did this (for validation purposes) I had to extend the
TabNavigator and override the selectedIndex setter method. I then
provided an inteface (ITabChild) that my views could implement.
When
the setter is called, you can then check if the child is an
ITabChild
and if so call the methods you define in that interface before
actually
setting the selected tab.

Thanks for the reply,
That doesn't work though. If I set up an IndexChangedEvent event
listener, calling event.preventDefault() doesn't stop the tab
from
changing.

Hi,
you can add an eventListener on the TabNavigator, listening for
an
IndexChangedEvent and do all your validations...
And if you need to cancel the current change, you could try an
evt.preventDefault();
private function changeIndex(evt:IndexChangedEvent):void
{
evt.preventDefault(); // cancel the changing
}

Assunto: [flexcoders] TabContainer with modules - how to cancel
Tab
change
I have a Flex Application that has a TabNavigator. Each tab
contains a
moduleLoader that loads a corresponding Module.
On some of these modules, I have a basic Form with Validators
connected
to it. I want to be able to make sure that the form values are
valid
before the user navigates away from the currently selected tab
by
clicking a new tab.
In other words, I want the Validator to fire when the user
clicks
on a
new tab and if there are any invalid values I want to prompt the
user
to fix them and stop the event propogation so the TabNavigator
stays on
the current tab.
How can I cancel the TabNavigator change?
