void GroupNode::recompute_boundrect (  void   )  [protected]

Here is the call graph for this function:

void GroupNode::recompute_scenerect (  void   )  [protected]

Here is the call graph for this function:

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

The default Event handler passes all events down to its children Reimplemented from BaseSceneNode. Reimplemented in BorderLayer< SP >, ContainerNode, HUDGroupNode, and LayerNode.

Here is the call graph for this function:

bool GroupNode::handle_event (  RepaintEvent *   )

Here is the call graph for this function:

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

The default Message handler just passes the request down to its children in hope that the target is one of them. Reimplemented from BaseSceneNode.

Here is the call graph for this function:

void GroupNode::reserve (  long   )

void GroupNode::add_child (  SceneNode *   )

Here is the call graph for this function:

void GroupNode::remove_child (  SceneNode *   )

Here is the call graph for this function:

void GroupNode::remove_child (  int  idx  )

void GroupNode::remove_all_children (  void   )

Here is the call graph for this function:

void GroupNode::add_child (  GroupNode *   )

Here is the call graph for this function:

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

This function should be overloaded in every node to provide for event handling and repaint. Implements BaseSceneNode. Reimplemented in BorderLayer< SP >, and HUDGroupNode.

Here is the call graph for this function:

void GroupNode::get_scenerect (  double &  , double &  , double &  , double &  )  [virtual]

This function is used to compute scene bounds. Certain types of nodes, e.g. HUDGroups will return an invalid rect here. get_boundrect() is aliased to get_boundrect in BaseSceneNode and there is normally no need to override it. Reimplemented from BaseSceneNode. Reimplemented in HUDGroupNode.

Here is the call graph for this function:

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

Reimplemented from BaseSceneNode.

Here is the call graph for this function:

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

Reimplemented from BaseSceneNode.

Here is the call graph for this function:

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

Reimplemented from BaseSceneNode.

Here is the call graph for this function:

bool GroupNode::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 GroupNode::listen_event (  Event *   )  [virtual]

Reimplemented from EventListener. Reimplemented in HUDGroupNode.

Here is the call graph for this function:

void GroupNode::toggle_dynamic (  bool   )

Here is the call graph for this function:

bool GroupNode::dynamic_boundrect [protected]

recomputing the boundrect at initial loading stage may slow down the app. Turn dynamic_boundrect off when you first load the children, then make sure to turn it back on if you have a dynamic scene. Default is true.

bool GroupNode::cache_boundrect [protected]

recomputing the boundrect at initial loading stage may slow down the app. Turn dynamic_boundrect off when you first load the children, then make sure to turn it back on if you have a dynamic scene. Default is true.
