[osg-users] moving camera from FirstPersonManipulator/StandardManipulator without mouse button

[OpenSceneGraph Users]

Found out!

Just needed to change the performMovement() function of the derived class, 
and add an extra else in the end:

    if( buttonMask == osgGA::GUIEventAdapter::LEFT_MOUSE_BUTTON )
    {
        return performMovementLeftMouseButton( eventTimeDelta, dx, dy );
    }
    else if( ( buttonMask == osgGA::GUIEventAdapter::MIDDLE_MOUSE_BUTTON ) 
||
             ( buttonMask == osgGA::GUIEventAdapter::RIGHT_MOUSE_BUTTON && 
modKeyMask & osgGA::GUIEventAdapter::MODKEY_CTRL ) ||
             ( buttonMask == (osgGA::GUIEventAdapter::LEFT_MOUSE_BUTTON | 
osgGA::GUIEventAdapter::RIGHT_MOUSE_BUTTON) ) )
    {
        return performMovementMiddleMouseButton( eventTimeDelta, dx, dy );
    }
    else if( buttonMask == osgGA::GUIEventAdapter::RIGHT_MOUSE_BUTTON )
    {
        return performMovementRightMouseButton( eventTimeDelta, dx, dy );
    }
    else
    {
        return performMovementLeftMouseButton( eventTimeDelta, dx, dy ); // 
<-- HERE
    }
