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.
afterTree void afterTree(): Called after the tree is drawn. Called before input events, so they can assume actions have completed.
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 root, Vector2 viewportSpace): Called before the tree is resized. Called before beforeTree.
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.
stop void stop(): Stop the action

Variables

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.
