I am trying to translate my objects in scene, when the right mouse button
is pressed. But it is not moving. Pls check the snippet.
[code]
//CSGraphicsView
//.h
class CSGraphicsView : public osgQt::GLWidget
{
Q_OBJECT
public:
CSGraphicsView(QWidget* parent=0);
~CSGraphicsView();
virtual void mousePressEvent(QMouseEvent *e);
virtual void mouseReleaseEvent(QMouseEvent *e);
virtual void mouseMoveEvent(QMouseEvent *e);
};
#endif // GVIEW_H
////////////////////////////////////////////.cpp
void CSGraphicsView::mousePressEvent(QMouseEvent *e)
{
if(e->button()==Qt::LeftButton)
{
QMessageBox msg;
msg.setText("Left Mouse pressed");
msg.exec();
}
else if(e->button()==Qt::RightButton)
{
//QMessageBox msg;
//msg.setText("Right Mouse pressed");
//msg.exec();
ViewerWidget* viewerWid = qobject_cast<ViewerWidget*>(parent());
viewerWid->getView()->getCamera()->setViewMatrix(::osg::Matrix::translate(1000.5,
0.0, 0.0));
}
else if(e->button()==Qt::MiddleButton)
{
QMessageBox msg;
msg.setText("Middle Mouse pressed");
msg.exec();
}
else
return;
}

Please tell me why is it not moving ??.....I want to implement a rotate
functionality on right mouse press button, a pan function on middle mouse
press function and a zoom function on wheel event. Any help is highly
appreciated. Thanks Sujan
