Functions

afterInput

void afterInput(bool )

afterTree

void afterTree()

beforeResize

void beforeResize(Node , Vector2 )

A branch action can only hook to draw calls of specific nodes. It cannot bind into these hooks.

beforeTree

void beforeTree(Node , Rectangle )

A branch action can only hook to draw calls of specific nodes. It cannot bind into these hooks.

filterAfterDraw

bool filterAfterDraw(Node node)

Branch action excludes the start node from results.

filterBeforeDraw

bool filterBeforeDraw(Node node)

Branch action excludes the start node from results.

stopped

void stopped()

Undocumented in source. Be warned that the author may not have intended to support it.

Inherited Members

From TreeAction

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.

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.

inStartNode

bool inStartNode()

inTree

bool inTree()

clearSubscribers

void clearSubscribers()

Remove all event handlers attached to this tree.

subscribe

void subscribe(Subscriber!() subscriber)

Undocumented in source. Be warned that the author may not have intended to support it.

stop

void stop()

Stop the action.

started

void started()

Called whenever this action is started — added to the list of running actions in the LayoutTree or TreeContext.

stopped

void stopped()

Called whenever this action is stopped by calling stop.

filterBeforeTree

bool filterBeforeTree()

filterAfterTree

bool filterAfterTree()

Determine whether beforeTree and afterTree should be called.

filterBeforeDraw

bool filterBeforeDraw(Node node)

filterAfterDraw

bool filterAfterDraw(Node node)

Determine whether beforeDraw and afterDraw should be called for the given node.

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.

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.

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.

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

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

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.

afterInput

void afterInput(bool keyboardHandled)

Hook that triggers after processing input. Useful if post-processing is necessary to, perhaps, implement fallback input.
