QGraphicsView issue - c++

Question

I dont understand what`s going on: when i create QGraphicsView object directly and adding scene with a pixmap, all is ok, pixmap appears on the screen:
scene.addPixmap(pix);
QGraphicsView graphicsView;
graphicsView.setScene(&scene);
But when i try to inherit QGraphicsView class with purpose of reimplementing events, nothing happend and i got white screen without pixmap, but events like changing cursor is working:
scene.addPixmap(pix);
DrawArea graphicsView;
graphicsView.setScene(&scene);
.h file:
class DrawArea : public QGraphicsView
{
Q_OBJECT
public:
DrawArea(QWidget *parent = 0);
~DrawArea();
signals:
public slots:
void mousePressEvent(QMouseEvent * e);
void paintEvent(QPaintEvent *);
void enterEvent(QEvent *e);
private:
QPoint coord;
};
.cpp file:
DrawArea::DrawArea(QWidget *parent)
: QGraphicsView(parent){
}
DrawArea::~DrawArea(){
}
void DrawArea::mousePressEvent(QMouseEvent * event){
}
void DrawArea::paintEvent(QPaintEvent *event){
}
void DrawArea::enterEvent(QEvent *event){
viewport()->setCursor(Qt::CrossCursor);
}
Tell me if something missed, Thanks in advance.

Answer 1

You should process your events. Try this:
void DrawArea::mousePressEvent(QMouseEvent * event)
{
//some actions
QGraphicsView::mousePressEvent(event);
}
void DrawArea::paintEvent(QPaintEvent *event)
{
//some actions
QGraphicsView::paintEvent(event);
}
Also I think that you don't need paintEvent at all, do all needed things in the scene.
