[Flashcoders] setSelection() with TextInput?
Hi all.
I've been beating my head against the wall for a bit, trying to get
Selection.setSelection() to work inside a component.
I've got this code, inside a component which happens to contain a TextInput:
private function focusIn(){
trace(answer_ti.text + ] received focus);
answer_ti.setFocus();
Selection.setSelection(0, answer_ti.text.length);
}
Which gets runs when answer_ti fires a focusIn event. This just doesn't
seem to work... the trace statement comes up, but I can't see the
selection change.
Is there anything I've overlooked? I tried to use Delegate for event
handling, but it didn't make a difference.
Thanks.

Re: [Flashcoders] setSelection() with TextInput?
Hi Haikal,
I've just been doing exactly the same thing for the past day -
beating my head against the wall for this same reason. I am not
working with any components, but trying to use setSelection within a
class to select text in a text field nested within a movieClip - and
getting the same non-result. Infuriating.
So, what I finally came up with that is a lame hack but seems to work
is using a setInterval to call setSelection a tenth of a second
later. So basically it's this:
class myClass
{
... (var declarations, constructor, etc.) ...
private function onMouseUp ():Void
{
clearInterval(selectionRunner);
selectionRunner = setInterval(this, selectString, 10);
}
private function selectString ()
{
clearInterval(selectionRunner);
Selection.setFocus(myField_txt);
Selection.setSelection(0, myField_txt.text.length);
}
... (mode methods, etc.) ...
}
If anyone else has a better solution (or even better, an explanation
why this problem occurs in the first place) I'd love to hear it.
Cheers,
-DB

Aha! That gives me an idea... I might try using doLater(), a method
available to components and see if that works.
Thanks for the tip.
