Member Function Documentation

virtual void LeafNode::paint (  Camera *   )  [pure virtual]

Implemented in ActiveLeaf.

virtual void LeafNode::get_boundrect (  double &  , double &  , double &  , double &  )  [pure virtual]

You must override this function to provide an accurate estimation of the bounding rectangle. Make sure the function is as "light" as possible because it will be called very often. Implements BaseSceneNode.

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

Reimplemented from BaseSceneNode.

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

Reimplemented from BaseSceneNode.

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

Reimplemented from BaseSceneNode.

bool LeafNode::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. Reimplemented in ActiveLeaf.

Here is the call graph for this function:

bool LeafNode::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 ActiveLeaf.

Here is the call graph for this function:

bool LeafNode::handle_event (  MouseEvent *   )

bool LeafNode::handle_event (  RepaintEvent *   )
