mouseMoveEvent(QMouseEvent* event), event->button()

[faraslacks]

I realise drag&drop actions on QTableView. My reimplemented mouseMoveEvent() looks so:

void
MyClass::mouseMoveEvent(QMouseMove* event)
{
    qDebug() << event->button();
    if (event->button() == Qt::LeftButton) {
        int distance = (event->pos() - fPressPos).manhattanLength();
        if (distance > QApplication::startDragDistance()) {
            startDrag();
        }
    }
    QTableView::mouseMoveEvent(event);
}

void
MyClass::mouseMoveEvent(QMouseMove* event)
{
    qDebug() << event->button();
    if (event->button() == Qt::LeftButton) {
        int distance = (event->pos() - fPressPos).manhattanLength();
        if (distance > QApplication::startDragDistance()) {
            startDrag();
        }
    }
    QTableView::mouseMoveEvent(event);
}

I execute my application and tried to move mouse with pressed left button above my widget. In debug messages I see 0. And function did not enter first condition. So move event called, but QMouseEvent not contains information about buttons pressed. I have not idea why it happening.

Oops, I solved my trouble myself... The condition must looks like this:

if (event->buttons() & Qt::LeftButton) {
    // code here
}

if (event->buttons() & Qt::LeftButton) {
    // code here
}
