Member Function Documentation

BaseSceneNode * SceneNode::get_child (  void   )  [virtual]

this one always returns NULL for BaseSceneNode. SceneNode and GroupNode override this function. Reimplemented from BaseSceneNode.

bool SceneNode::handle_event (  Event *   )  [virtual]

call the base event handler in all nodes because it provides checks for node visibility and mouse event fitting into bounding rectangle. Reimplemented from BaseSceneNode. Reimplemented in CursorPolicyNode, EventFilter, AreaFilter, and ZoomSceneNode< ZP, maxzoom >.

Here is the call graph for this function:

bool SceneNode::handle_message (  Message *   )  [virtual]

messages are intended to a certain node but can be processed by nodes directly higher up (i.e. decorator nodes). Beware that this can be slow for large graphs but using smart group nodes can help. Reimplemented from BaseSceneNode.

Here is the call graph for this function:

void SceneNode::get_boundrect (  double &  , double &  , double &  , double &  )  [virtual]

This function should be overloaded in every node to provide for event handling and repaint. Implements BaseSceneNode.

Here is the call graph for this function:

bool SceneNode::check_event_fitspixels (  Event *   )  [virtual]

This function should be overloaded in every node to provide for event handling. Implements BaseSceneNode.

Here is the call graph for this function:

void SceneNode::register_event_listener (  const char *  , EventListener *  )  [virtual]

Reimplemented from EventHub.

Here is the call graph for this function:

void SceneNode::unregister_event_listener (  const char *  , EventListener *  )  [virtual]

Reimplemented from EventHub.

Here is the call graph for this function:

void SceneNode::translate (  double  dx, double  dy )  [virtual]

Reimplemented from BaseSceneNode.

Here is the call graph for this function:

void SceneNode::rotate (  double  ax, double  ay, double  rad )  [virtual]

Reimplemented from BaseSceneNode.

Here is the call graph for this function:

void SceneNode::move (  double  newx, double  newy )  [virtual]

Reimplemented from BaseSceneNode.

Here is the call graph for this function:

void SceneNode::add_child (  BaseSceneNode *   )
