Hello there,

i have a problem with QGraphicsItem tranformation there is a link what i expect and what is happening http://i52.tinypic.com/mvn5gz.png, and here is the code ;

Qt Code:

Switch view

//origin point is center of item
QTransform newTransform =  QTransform().translate( origin.x(), origin.y() ).scale( 2, 1 )
                              .translate( -origin.x(), -origin.y() );
    setTransform( newTransform, true);
 
//origin point could be change here but for now same center of item.
    newTransform = QTransform().translate( origin.x(), origin.y() ).rotate( 90 )
                        .translate( -origin.x(), -origin.y() );
    setTransform(newTransform, true);

//origin point is center of item
QTransform newTransform =  QTransform().translate( origin.x(), origin.y() ).scale( 2, 1 )
                              .translate( -origin.x(), -origin.y() );
    setTransform( newTransform, true);

//origin point could be change here but for now same center of item.
    newTransform = QTransform().translate( origin.x(), origin.y() ).rotate( 90 )
                        .translate( -origin.x(), -origin.y() );
    setTransform(newTransform, true);
