How do draw a frame in QListView?

[wysota]

Can we see the code along with the class declaration?

[someralex]

class myView : public QListView
{
    Q_OBJECT
public:
    myView(QWidget *parent = 0);
protected:
    void paintEvent(QPaintEvent *event);
private:
 
};
 
myView::myView(QWidget *parent)
    : QListView(parent)
{
}
 
void myView::paintEvent(QPaintEvent *event)
{
    QPainter painter(this);
    QPen pen(Qt::green, 10, Qt::SolidLine, Qt::RoundCap, Qt::RoundJoin);
    painter.setPen(pen);
    painter.drawRect(rect());
    QListView::paintEvent(event);
}

class myView : public QListView
{
    Q_OBJECT
public:
    myView(QWidget *parent = 0);
protected:
    void paintEvent(QPaintEvent *event);
private:

};

myView::myView(QWidget *parent)
    : QListView(parent)
{
}

void myView::paintEvent(QPaintEvent *event)
{
    QPainter painter(this);
    QPen pen(Qt::green, 10, Qt::SolidLine, Qt::RoundCap, Qt::RoundJoin);
    painter.setPen(pen);
    painter.drawRect(rect());
    QListView::paintEvent(event);
}

To copy to clipboard, switch view to plain text mode 

[wysota]

The code looks correct. You don't call the paintEvent yourself, do you?

[jpn]

It should be:

QPainter painter(viewport());

QPainter painter(viewport());

To copy to clipboard, switch view to plain text mode 

Which is mentioned in the docs QAbstractScrollArea::paintEvent():

Note: If you open a painter, make sure to open it on the viewport().
