mouseMoveEvent works only if mouse is clicking

  • Hi,
    i'm trying to use mouseMoveEvent function in order to tracking the position of the mouse. But it works only if i hold the mouse button. I need it works always.
    Thank you

    MainWindow::MainWindow(QWidget *parent) :
    ui(new Ui::MainWindow)



    delete ui;

    void MainWindow::mouseMoveEvent(QMouseEvent *event){

    QPoint pos=mapFromGlobal(QCursor::pos());
    qDebug() << pos << endl;
    if(QWidget::childAt(pos.x(),pos.y())) ui->INFO->setText(QWidget::childAt(pos.x(),pos.y() )->whatsThis());
    else ui->INFO->clear();

    You are not calling the base class implementation nor are you handling the event itself so it gets lost.
