Cannot connect (null)::selectionChanged to QTableView

Question

I have the following promoted QTableView:

class QRightClickableTableView : public QTableView {
  Q_OBJECT
public:
  explicit QRightClickableTableView(QWidget         


        

Answer 1

The signal slot connection has failed since table->selectionModel() has returned null.

If you set the model for your table before making signal slot connection, table->selectionModel() will return a valid model, making the signal slot connection successful.
