Halcyon is JavaFX framework for designing dockable multiple window applications. It supports legacy Swing components and accomodates other non Swing/JavaFX components.

Halcyon provides basic interfaces which are Console and TreePanel. ConsolePane is linked with standard out and standard error streams. TreePanel contains all other HalcyonNode instances.

This framework consists of model and view/controller.

Halcyon holds normally three basic types of nodes, which are Console, ToolBar and TreePanel. HalcyonFrame is the entry point to create GUI based on JavaFX stage. Console is used as console output/error as well as logging printing panel. ToolBar is used for providing control panels where user can operate tasks. TreePanel is a kind of hub to manage all the other mission specific jobs. For example, we can use this as DeviceTree where multiple devices appear in a tree structure. Each device is shown by clicking the specific tree node and controlled in the device panel.

Halcyon is based MVC pattern where Model/View/Controller are separated and linked by EventHandlers.

1. HalcyonNode - JavaFX based node
2. HalcyonSwingNode - Swing based node
3. HalcyonOtherNode - neither JavaFX nor Swing based (e.g. OpenGL window)

1. HalcyonNodeRepository - Halcyon node collection

1. NodeProperty - holds a javafx.scene.Node instance in HalcyonNode.

1. HalcyonPanel - contains HalcyonNode.
2. ConsolePanel - used for Console output.
3. TreePanel - holds multiple HalcyonPanel containing one of HalcyonNode in a tree structure. When clicking specific node, the corresponding HalcyonNode opens an appropriate GUI component.

1. ViewManager - a controller for coordinating view and model according to user interactions.

1. RunFX - can run all RunnableFX the inherited class.
2. RunnableFX - an interface which can be run by RunFX.

1. DemoHalcyonMain - an entry point of the demo application.
2. DemoHalcyonNodeType - has custom-made HalcyonType enumeration elements. This will be used for mapping the icons in the TreePanel.
3. DemoResourceUtil - a resource access utility only for demonstration. It contains where the icon files are located.
4. DemoToolbarPanel - contains a user-defined Toolbar which will be located in Toolbar Area in the Pane.
