Creating Custom Ellipse Button

[VireX]

I tried this code then did QEllipseButton b; b.setText("woot"); b.show(); in a simple window of Qt, and it will not show the area. I tried r3, and r1, update,setting a background... but it wont make me a button with a different size.

Like I would like to make an egg shaped button that works just like a pushbutton, but has a nice background image on it.

class QEllipseButton : public QPushButton {
  public:
    QEllipseButton(QWidget * parent = 0): QPushButton(parent){
    }
  protected:
    void paintEvent ( QPaintEvent * event ){
     QRegion r1(QRect(200, 50, 500, 400),    // r1: elliptic region
                QRegion::Ellipse);
     QRegion r2(QRect(200, 70, 90, 30));    // r2: rectangular region
     QRegion r3 = r1.intersected(r2);        // r3: intersection
 
     QPainter painter(this);
     painter.setClipping(true);
     painter.setClipRegion(r1);
     //QBrush brush(QColor(255,0,0,255));
     //painter.setBackground(brush);
     //update();
    }
};

class QEllipseButton : public QPushButton {
  public:
    QEllipseButton(QWidget * parent = 0): QPushButton(parent){
    }
  protected:
    void paintEvent ( QPaintEvent * event ){
     QRegion r1(QRect(200, 50, 500, 400),    // r1: elliptic region
                QRegion::Ellipse);
     QRegion r2(QRect(200, 70, 90, 30));    // r2: rectangular region
     QRegion r3 = r1.intersected(r2);        // r3: intersection

     QPainter painter(this);
     painter.setClipping(true);
     painter.setClipRegion(r1);
     //QBrush brush(QColor(255,0,0,255));
     //painter.setBackground(brush);
     //update();
    }
};

To copy to clipboard, switch view to plain text mode 

thx for help.
