Where are you doing that findChild? A non-native QFileDialog is lazily 
populated. Typically you need to wait until a show event gets delivered 
and handled by it to be sure you'll have the widgets created.

Random notes:

1) As many others have told you, this may be symptomatic of bad design...

2) That's an API abuse, hence totally unsupported and can break again at 
any time.

HTH,
