drawing points based on mouse clicks, how to create handle event for mouse clicks

[Not Fast Enough]

hi, I have a small problem in knowing the position of a mouse on a QGraphicsViewScene. How can i know the x,y and handle clicks to draw points in their place and later create a shape filled with black color.
regards

You use the mouse events of the scene.

thanks, i was alble to use mousePressEvent and was able to update the cooirdinates in a lable but i couldn't use QGraphicsSceneMouseEvent, i changed (QMouseEvent to QGraphicsSceneMouseEvent) but it didnt return anything. the problem is that the cooirdinates are relative to the main window not my GraphicsView. please see attached image for demonstration.

void MainWindow::mousePressEvent(QMouseEvent *mouseEvent)
 
{
 
        QVariant x(mouseEvent->x());
        QVariant y(mouseEvent->y());
        ui->lblX->setText(x.toString());
        ui->lblY->setText(y.toString());
}

void MainWindow::mousePressEvent(QMouseEvent *mouseEvent)

{

        QVariant x(mouseEvent->x());
        QVariant y(mouseEvent->y());
        ui->lblX->setText(x.toString());
        ui->lblY->setText(y.toString());
}

for any one who reads this i did it using QEventFilter.
this topic was helpful: http://www.qtcentre.org/threads/6272...cking-on-image

this is the code i use:
in header file:

bool eventFilter(QObject *o, QEvent *e);

bool eventFilter(QObject *o, QEvent *e);

in .cpp

//filter mouse tracking to the selection area only
bool MainWindow::eventFilter(QObject *o, QEvent *e){
  if(o!= lblScrollImage) return false;
  if(e->type()==QEvent::MouseMove){
    QMouseEvent *mev = static_cast<QMouseEvent*>(e);
    QVariant x(mev->pos().x());
    QVariant y(mev->pos().y());
    ui->lblX->setText(x.toString());
    ui->lblY->setText(y.toString());
    //polyPoints << QPoint(x.toInt(), y.toInt());
  }
  else if (e->type()==QEvent::MouseButtonPress)
  {
      QMouseEvent *mev = static_cast<QMouseEvent*>(e);
      QVariant x(mev->pos().x());
      QVariant y(mev->pos().y());
      ui->lblX->setText(x.toString());
      ui->lblY->setText(y.toString());
      ui->lineEditX->setText(x.toString());
      ui->lineEditY->setText(y.toString());
      polyPoints << QPoint(x.toInt(), y.toInt());
  }
  return false;
}

//filter mouse tracking to the selection area only
bool MainWindow::eventFilter(QObject *o, QEvent *e){
  if(o!= lblScrollImage) return false;
  if(e->type()==QEvent::MouseMove){
    QMouseEvent *mev = static_cast<QMouseEvent*>(e);
    QVariant x(mev->pos().x());
    QVariant y(mev->pos().y());
    ui->lblX->setText(x.toString());
    ui->lblY->setText(y.toString());
    //polyPoints << QPoint(x.toInt(), y.toInt());
  }
  else if (e->type()==QEvent::MouseButtonPress)
  {
      QMouseEvent *mev = static_cast<QMouseEvent*>(e);
      QVariant x(mev->pos().x());
      QVariant y(mev->pos().y());
      ui->lblX->setText(x.toString());
      ui->lblY->setText(y.toString());
      ui->lineEditX->setText(x.toString());
      ui->lineEditY->setText(y.toString());
      polyPoints << QPoint(x.toInt(), y.toInt());

  return false;
