Functions in detail

HandlerDispatcher.activateDispatcher! ( in Key key, io Boolean isAccepted )

Activates a specific dispatcher within the manipulation tree and its parents and children dispatcher. Must be called from the manipualtion-tree root dispatcher.

注釈

This is applied to the manipulation tree leaves, e.g. the tools.

HandlerDispatcher.activateHandlers! ( io Key key, io Boolean switchDisableNone, io Boolean switchDisableOthers, io Boolean switchDisableAll, io Boolean isAccepted )

Activates one or several handlers within this dispatcher stack. Recursive call that visit the whole manipulation tree. Must be called from the manipualtion-tree root dispatcher.

注釈

This is applied to the manipulation tree leaves, e.g. the tools.

Ref<EventHandler> HandlerDispatcher.getActiveHandler? ()

Gets a reference to the current handler.

String HandlerDispatcher.getHandlerName? ( in Ref<EventHandler> handler )

Gets the handler’s name.

Boolean HandlerDispatcher.hasHandler? ( in String name )

Gets true if a handler with the given name has been registered.

HandlerDispatcher.processKeyEvent! ( io Event event )

Process a key event + manages tool switching.

HandlerDispatcher.processMouseEvent! ( io Event event )

Process a mouse event.

HandlerDispatcher.registerHandler! ( in String name, io Ref<EventHandler> handler )

Registers a new handler with a given name.

HandlerDispatcher.sceneChanged! ()

Updates the manipulation-tree as the scene might have changed.

HandlerDispatcher.setActiveHandler! ( in Ref<EventHandler> handler )

Activates a specific handler in the stack. It will receive the events.

HandlerDispatcher.setActiveHandler! ( in String name )

Activates a specific handler in the stack. It will receive the events.

HandlerDispatcher.unregisterHandler! ( in Ref<EventHandler> handler )

Unregisters an existing handler.

HandlerDispatcher.unregisterHandler! ( in String name )

Unregisters an existing handler.
