You don't have to subclass it, just connect some slot to
void QApplication::focusChanged ( QWidget * old, QWidget * now )
Check if "new" is you lineedit and do whatever you must.

I however agree that clearing is likely a bad idea (assume you just wanted to 
fix a one char typo) - you might want to selectAll() instead?


Cheers,
Thomas
