You could use the findChildren function of QObject and get a list of all children of a widget that can be casted to the given type. Eg

QList<QTableView*> allTableViews = glWidget->findChildren<QTableView *>();
// Iterate in order to find the table view either by checking the name, the parent etc....

Another approach would be the one Simon suggests, subclassing and adding public access function to the members you want to be reachable from top level widgets.
