[Interest] Wrong mouse move events.

[Igor Mironchik]

Hi guys,

In the following code:

//! Pressed?
bool pressed;
//! Position.
QPoint pos;
//! Mouse move delta.
int delta;

void
Envelope::mousePressEvent( QMouseEvent * e )
{
        if( e->button() == Qt::LeftButton )
        {
                d->pressed = true;
                d->pos = e->pos();
                d->delta = 0;
        }

        e->accept();
}

void
Envelope::mouseMoveEvent( QMouseEvent * e )
{
        if( d->pressed )
        {
                const QPoint delta = d->pos - e->pos();

                d->delta += delta.manhattanLength();

                d->pos = e->pos();

                e->accept();

                emit moved( delta.x() );
        }
        else
                e->ignore();
}

emit moved( delta.x() ) emits the next deltas with one direction mouse  
move:

12
-10
11
-9

etc.

I can't understand what I am doing wrong. Is this my mistake, or my mouse  
is broken, or something else?

Thank you.
