Question

I’m working on an application in Flex 3.2, and I need to be able to tell whether the current focus is a textbox or not. How would I go about doing this? There’s more than one textbox in my application, so I can’t really set multiple event handlers for focusOut, etc.

Thanks,
Matt

You can accomplish this by using the stage.focus property. It holds the instance of whatever object has the focus.

So in whatever spot you want to do the check, just do this:

if(stage.focus is TextField){
    //do whatever you'd like to do
}

I’m not really a flex user, but I’m pretty sure the text components use TextFields inside them and that the focus will still be a TextField class. Someone please correct me if I’m mistaken.
