QRubberBand class to draw a line

[vermarajeev]

Hi how to use QRubberBand class to draw a line. According to docs, we can either draw a rectangle or a line. I'm able to draw a rectangle but not a line. Here is the sample code I have tried

Myline::Myline(  QWidget *parent, Qt::WFlags flags)
: QWidget(parent, flags){
	RBand = 0;
}
 
void Myline::mousePressEvent(QMouseEvent *event){
     first_pt = event->pos();
     last_pt = event->pos();
     if (!RBand)
	 RBand = new QRubberBand(QRubberBand::Line, this);
     RBand->setGeometry(QRect(first_pt, last_pt));
     RBand->show();
 }
 
 void Myline::mouseMoveEvent(QMouseEvent *event) {
	last_pt = event->pos();	
	RBand->setGeometry(QRect(first_pt, last_pt));
 }
 
 void Myline::mouseReleaseEvent(QMouseEvent *event) {
	last_pt = event->pos();
    RBand->hide();
 }

Myline::Myline(  QWidget *parent, Qt::WFlags flags)
: QWidget(parent, flags){
	RBand = 0;
}

void Myline::mousePressEvent(QMouseEvent *event){
     first_pt = event->pos();
     last_pt = event->pos();
     if (!RBand)
	 RBand = new QRubberBand(QRubberBand::Line, this);
     RBand->setGeometry(QRect(first_pt, last_pt));
     RBand->show();
 }

 void Myline::mouseMoveEvent(QMouseEvent *event) {
	last_pt = event->pos();	
	RBand->setGeometry(QRect(first_pt, last_pt));
 }

 void Myline::mouseReleaseEvent(QMouseEvent *event) {
	last_pt = event->pos();
    RBand->hide();
 }
