Working with QFocusData

[Crazy Sage]

Hi all.

I have folowing question:
As I understood this->focusData() returns tabbing order list for all widgets that are childs to the parent of this.

If this is right, then why following code goes to the infinite loop
@QFocusData* data=this->focusData();
data->home();
while(data->focusWidget()!=this)
data->next();@

If I don't understand principles by which QFocusData works, then how can I get widget that is after or before this in tabbing order? (this can have no focus at the moment, so findNextPrevChild doesn't work).--

Understood most problems, only problem with QFocusData remains.
