Constructor & Destructor Documentation

Member Function Documentation

bool DefaultCursorNode::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.

Here is the call graph for this function:

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

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