Accessing elements of the child user interface in the Qt interface

Question

I defined a UI (let me have myUI) to use the Qt constructor and use it in my applications. I need to access all sub-widgets ( QToolButtons) in myUI. I want to get all the subspecies as QObjectList.

Is there any way to do this?

QObject::children()does not work here because the Qt UI compiler, when converting a .ui file to a C ++ class, does not define the ui_myUI class as a subclass of any derived class QObject. Is there a way to get this to do this and then use the function children()?

Thank.
