This morning I had what seemed like a very simple task to complete, add a tab order to a small login form in an AIR app we're building. Several hours later I still had not accomplished this. I'm the first to admit that after a year or so of managing a team and not doing much hands on development my Flex skills are a bit rusty but this was ridiculous. The login form is in a modal popup window. Turns out that was m problem. When I would hit "Tab" the focus would jump back to the fields in the main application window. To fix this I created a FocusManager instance for the login screen and then activated it when the screen loaded. Once the screen was "activated" it held the focus while I tabbed through the form fields on that screen. Happy day. The FocusManager snippet is below, it's pretty simple, only two lines.
//grab focus for the popup window so tabIndex works. var fm:FocusManager = new FocusManager(this); fm.activate();
Thanks you just saved me loads of time.
For some reason that didn’t quite work for me, as the first tabstop component wasn’t selected.
What did work is this:
In creationComplete:
this.setFocus();
var comp:IFocusManagerComponent = focusManager.getNextFocusManagerComponent();
if (comp)
{
focusManager.setFocus(comp);
}
Be careful. Creating a new FocusManager can have unintended side effects (like the defaultButton processing might mysteriously stop working).
I had the exact same issue — at app startup, a login screen popped up over the main window, but Tabbing in the popup returned the focus to controls in the main application, not the popup. After setting breakpoints in FocusManager.as, I realized that the main application’s FocusManager was getting re-activated after the popup was created. It all had to do with the timing of the creation of the popup. I moved the creation of the popup to after all of the main application windows had been created, and presto! Tabbing and defaultButton worked again.
I was just looking for the exact same problem. Thanks for sharing mate!!!
