How to correctly inherit a QT widget?

Question

Qt

The task is to make a slot to call the function by double clicking on the widget from QWidgetList.
With the help of qt designer, I kind of made promoted widgets, this is how the header file described:

class FilesView : public QWidget
{
    Q_OBJECT;
public:
    FilesView(QWidget *parent = 0);
};

and the implementation itself

FilesView::FilesView(QWidget* parent)
        : QListWidget(parent)
{}

when compiling, it gives errors about the absence of QListWidget methods. Aren't they inherited? CHADNT?

Answer 1

You need to inherit from QListWidget ...
