mouseMoveEvent works only if mouse is clicking

FED27

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) :
QMainWindow(parent),
ui(new Ui::MainWindow)
{

ui->setupUi(this);
setMouseTracking(true);

}

MainWindow::~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();

}

Hi,

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