Profiling an application in Mac OS X

Finding which process to profile

If your system is running slowly, perhaps a process is using too much CPU time and won't let other processes run smoothly. To find out which processes are taking up a lot of CPU time, you can use Apple's Activity Monitor.

The CPU pane shows how processes are affecting CPU (processor) activity:

class FooTableModel : public QAbstractTableModel {
    Q_OBJECT
   public:
    FooTableModel(QObject *parent = nullptr);
    // readonly tables
    Qt::ItemFlags flags(const QModelIndex &index)
        const override;  // editable can return: Qt::ItemIsEditable
    QVariant data(const QModelIndex &index,
                  int role = Qt::DisplayRole) const override;
