Interface ApplicationListener

All Known Implementing Classes:
ApplicationCore
public interface ApplicationListener

An ApplicationListener is called when the Application is created, resumed, rendering, paused or destroyed. All methods are called in a thread that has the OpenGL context current. You can thus safely create and manipulate graphics resources.

The ApplicationListener interface follows the standard Android activity life-cycle and is emulated on the desktop accordingly.

  • Method Details

    • init

      default void init()
      Called when the Application is first created. Only gets called if the application is created before the listener is added.

    • resize

      default void resize(int width, int height)
      Called when the Application is resized. This can happen at any point during a non-paused state but will never happen before a call to init().
      Parameters:
      width - the new width in pixels
      height - the new height in pixels

    • update

      default void update()
      Called when the Application should update itself.

    • pause

      default void pause()
      Called when the Application is paused, usually when it's not active or visible on screen. An Application is also paused before it is destroyed.

    • resume

      default void resume()
      Called when the Application is resumed from a paused state, usually when it regains focus.

    • dispose

      default void dispose()
      Called when the Application is destroyed. Preceded by a call to pause().

    • exit

      default void exit()
      Called when the applications exits gracefully, either through `Core.app.exit()` or through a window closing. Never called after a crash, unlike dispose().

    • fileDropped

      default void fileDropped(Fi file)
      Called when an external file is dropped into the window, e.g from the desktop.
