I am trying to implement my own pan functionality in osg scene using Qt.
Please tell me if it is right ?.....But it's not happening.
Check my snippet.
void CSGraphicsView::mousePressEvent(QMouseEvent *e)
{
lastPos = e->pos();
}
void CSGraphicsView::mouseMoveEvent(QMouseEvent *e)
{
float dx = (e->y() - lastPos.y());
float dy = (e->x() - lastPos.x());
const bool panFlag = ( e->buttons() & Qt::MidButton );
const bool rotateFlag = ( e->buttons() & Qt::LeftButton );
const bool zoomFlag = ( e->buttons() & Qt::RightButton );
if ( zoomFlag )
{
zoom( dy );
}
else if ( rotateFlag )
{
rotate( dx, dy );
}
else if ( panFlag )
{
pan( dx, dy );
}
viewer->frame();
lastPos = e->pos();
}
void CSGraphicsView::pan( int dx, int dy )
{
viewer->getView()->getCamera()->setViewMatrix(osg::Matrix::translate(dx,dy,0));
}
//viewer is composite viewer osg
//getView() returns the osgViewer::View
//but my object is not moving what s wrong in this. please help.
