I'm subclassing a QFileDialog. I need to get a pointer to the filename box. I was doing this with findChild<QLineEdit*>() with Qt4 but with Qt5 this returns null. Any suggestions?
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.
