void rviz::InteractiveMarkerControl::handle3DCursorEvent ( ViewportMouseEvent  event,
const Ogre::Vector3 &  cursor_3D_pos,
const Ogre::Quaternion &  cursor_3D_orientation 
) [virtual]

This is the main entry-point for interaction using a 3D cursor.

The ViewportMouseEvent struct is used to "fake" a mouse event. An event must have the panel, viewport, and type members filled in. The acting_button and buttons_down members can be specified as well, if appropriate. All other fields are currently ignored.

A sample construction of a "right-button mouse-up" event:

 ViewportMouseEvent event;
 event.panel = context_->getViewManager()->getRenderPanel();
 event.viewport = context_->getViewManager()->getRenderPanel()->getRenderWindow()->getViewport(0);
 event.type = QEvent::MouseButtonRelease;
 event.acting_button = Qt::RightButton;
 event.buttons_down = Qt::NoButton;

For more examples, see the implementation in the interaction_cursor_rviz package.

Parameters:
eventA struct holding certain event data (see description above).
cursor_posThe world-relative position of the 3D cursor.
cursor_rotThe world-relative orientation of the 3D cursor.
control_nameThe name of the child InteractiveMarkerControl calling this function.

void rviz::InteractiveMarkerControl::interactiveMarkerPoseChanged ( Ogre::Vector3  int_marker_position,
Ogre::Quaternion  int_marker_orientation 
)

Update the pose of the interactive marker being controlled, relative to the reference frame. Each InteractiveMarkerControl maintains its pose relative to the reference frame independently, so when the parent InteractiveMarker mvoes, it calls this function on all its child controls.

Represents the local frame of this control relative to reference node/frame. There is no intermediate InteractiveMarker node or frame, each control keeps track of its pose relative to the reference frame independently. In INHERIT mode, this will have an identical pose as the rest of the interactive marker, otherwise its orientation might be different.
