Bordered Line/ Point or any closed Figure

Hi,
As for many days I was trying to get a line or point or any closed figure which will have borders around it. By use of QPainter with specific QPen or QBrush it is drawing (using drawLine, drawpoint, drawPolyline etc) only single color figure.
Is there any way to get closed figure with border around line. Attachment 12453

Use QPainterPath

Actually I searched for possibility of doing this but could find any way, even with QPainterPath. Can you please tell me how to use QPainterPath for the same?

Not sure what exactly what you want to do, anyway here is an example to use QPainterPath.

Code:

class MyWidget : public QWidget
{
public:
    explicit MyWidget(QWidget * parent = 0)
        : QWidget(parent) { }
 
protected:
    void paintEvent(QPaintEvent * event)
    {
        QPainter painter(this);
 
        QPainterPath path;
 
        const QRect rect = event->rect();
        const QPoint center = rect.center();
        const int height = rect.height() / 4;
        const int width = rect.width() / 4;
 
        path.moveTo(center);
        path.moveTo(center.x()          , center.y() - height);
        path.lineTo(center.x() + width  , center.y() - height);
        path.lineTo(center.x() + width  , center.y());
        path.lineTo(center.x() + width  , center.y() + height);
        path.closeSubpath();
 
        painter.setPen(QPen(QBrush(Qt::red), 5));
        painter.drawPath(path);
        painter.fillPath(path, QBrush(Qt::CrossPattern));
    }
};
 
int main(int argc, char *argv[])
{
    QApplication app(argc, argv);
 
    MyWidget widget;
    widget.show();
 
    return app.exec();
}
