A class for iterating over the node tree.

Functions

afterDraw void afterDraw(Node node, Rectangle space, Rectangle paddingBox, Rectangle contentBox)
void afterDraw(Node node, Rectangle space): Called after each drawImpl call of any node in the tree, so supplying children nodes before their parents.
afterDrawImpl void afterDrawImpl(Node node, Rectangle space, Rectangle paddingBox, Rectangle contentBox): internal
afterInput void afterInput(bool keyboardHandled): Hook that triggers after processing input. Useful if post-processing is necessary to, perhaps, implement fallback input.
afterResize void afterResize(Node node, Vector2 viewportSpace): Called after a node is resized.
afterResizeImpl void afterResizeImpl(Node node, Vector2 viewport): Undocumented in source. Be warned that the author may not have intended to support it.
afterTree void afterTree(): Called after the tree is drawn. Called before input events, so they can assume actions have completed.
afterTreeImpl void afterTreeImpl(): Undocumented in source. Be warned that the author may not have intended to support it.
beforeDraw void beforeDraw(Node node, Rectangle space, Rectangle paddingBox, Rectangle contentBox)
void beforeDraw(Node node, Rectangle space): Called before each drawImpl call of any node in the tree, so supplying parent nodes before their children.
beforeDrawImpl void beforeDrawImpl(Node node, Rectangle space, Rectangle paddingBox, Rectangle contentBox): internal
beforeResize void beforeResize(Node node, Vector2 viewportSpace): Called before a node is resized.
beforeResizeImpl void beforeResizeImpl(Node node, Vector2 viewport): Undocumented in source. Be warned that the author may not have intended to support it.
beforeTree void beforeTree(Node root, Rectangle viewport): Called before the tree is drawn. Keep in mind this might not be called if the action is started when tree iteration has already begun.
beforeTreeImpl void beforeTreeImpl(Node root, Rectangle viewport): Undocumented in source. Be warned that the author may not have intended to support it.
clearSubscribers void clearSubscribers(): Remove all event handlers attached to this tree.
filterAfterDraw bool filterAfterDraw(Node node): Determine whether beforeDraw and afterDraw should be called for the given node.
filterAfterTree bool filterAfterTree(): Determine whether beforeTree and afterTree should be called.
filterBeforeDraw bool filterBeforeDraw(Node node): Determine whether beforeDraw and afterDraw should be called for the given node.
filterBeforeTree bool filterBeforeTree(): Determine whether beforeTree and afterTree should be called.
inStartNode bool inStartNode()
inTree bool inTree()
started void started(): Called whenever this action is started — added to the list of running actions in the LayoutTree or TreeContext.
stop void stop(): Stop the action.
stopped void stopped(): Called whenever this action is stopped by calling stop.
subscribe void subscribe(Subscriber!() subscriber): Undocumented in source. Be warned that the author may not have intended to support it.

Variables

generation int generation;: Keeps track of the number of times the action has been started or stopped. Every start and every stop bumps the generation number.
startNode Node startNode;: Node to descend into; beforeDraw and afterDraw will only be emitted for this node and its children.
toStop bool toStop;: If true, this action is complete and no callbacks should be ran.
