You're making an array of 10 QPointF's. The first element of the array  
contains mousePosX,mousePosY; the rest would contain default- 
constructed QPointF's. Then you draw it. You're getting only one  
QPointF in your array, the latest mouse press.

You need to build the array (or a QPolygon) inside mousePressEvent().
