Lucy comes with a variety of customizable frontend implementations. This diverse offering ensures that you can integrate Lucy in different kinds of applications.

To help choose your frontend, first ask yourself these questions:

  • Do I want to use the hardware-accelerated 2D/3D Lightspeed map or the non-accelerated 2D GXY map? Choose your technology stack discusses these options.

  • Is the map the main focus of the application?

  • Is the application limited to a single map or should it show more than one map?

  • In what way does the end-user need to customize the frontend?

The dockable frontends of Lucy and Lucy GXY

The dockable frontend offers a flexible, dockable application pane configuration with these features:

  • The end-user can dock, undock, move, and resize panes.

  • You can save custom layouts into the workspace.

  • You can open many maps at the same time.

  • It supports 2D/3D Lightspeed maps, or 2D GXY maps in the case of Lucy GXY.

The frontend is suitable for applications where the map is just a part of a larger application that displays many extra user interface components to cover other requirements.

This frontend is the default frontend used by the TLcyMain class. To start it from a LuciadLightspeed release, simply run Lucy.bat or, depending on your operating system.

To start a dockable frontend configured with a 2D Lucy GXY map, run the appropriate GXY equivalent script: LucyGXY.bat or In Lucy GXY, you can still start a 3D map alongside the initially launched 2D map.

The Lucy user guide offers a visual overview of the dockable frontend.

The map-centric frontend

The map-centric frontend gives the map a central role in the application. It has these features:

  • Most of the screen real estate is dedicated to the map.

  • It uses a dark look and feel, putting even more focus on the map.

  • It uses a single map that can easily switch between 2D and 3D visualization.

  • The toolbar and menu bar of the dockable frontend merge into just one bar in the map-centric frontend. It offers a smaller set of functions, focused on loading and exploring data.

  • Various tasks require less user interaction:

    • The table view and profile view are always available below the map. Users can expand them when necessary.

    • Auxiliary panels such as the Map layers and Object properties in the screenshot are overlaid on the map. Users can expand them when necessary.

    • Time controls automatically appear when time-related data is available.

    • Users can access an extra toolbar to draw annotations on the map.

  • These features are all available as sample code. As a result, you can use it as a starting point for your own application and fully customize it where necessary.

To launch a map-centric configuration of Lucy, you can start Lucy Map Centric from the LuciadLightspeed launcher, or you can start the LucyMapCentric script.

LuciadLightspeed comes with more sample frontends:

  • samples.lucy.frontend.tabbedpanes: a simpler version of the dockable frontend based on JTabbedPane, offering less complexity and less flexibility to the end-user

  • samples.lucy.frontend.internalframes: a multiple-document interface (MDI) frontend that models panes as JInternalFrame instances

  • samples.lucy.frontend.granteddockableframes: a sample frontend implementation with the same features as the default dockable frontend

You can start all these frontends as samples from the LuciadLightspeed launcher.

Designing a custom frontend

You can also write a completely custom frontend with unlimited flexibility with respect to the user interface. See Creating a custom front-end application for an explanation. This article also discusses technical details of the available sample frontends.
