init

public void init(GLAutoDrawable drawable)

Description copied from interface: GLEventListener

Called by the drawable immediately after the OpenGL context is initialized. Can be used to perform one-time OpenGL initialization per GLContext, such as setup of lights and display lists.

Note that this method may be called more than once if the underlying OpenGL context for the GLAutoDrawable is destroyed and recreated, for example if a GLCanvas is removed from the widget hierarchy and later added again.

Specified by:

init in interface GLEventListener

reshape

public void reshape(GLAutoDrawable drawable,
           int x,
           int y,
           int width,
           int height)

Description copied from interface: GLEventListener

Called by the drawable during the first repaint after the component has been resized. The client can update the viewport and view volume of the window appropriately, for example by a call to GL.glViewport(int, int, int, int); note that for convenience the component has already called glViewport(x, y, width, height) when this method is called, so the client may not have to do anything in this method.

Specified by:

reshape in interface GLEventListener

display

public void display(GLAutoDrawable drawable)

Description copied from interface: GLEventListener

Called by the drawable to initiate OpenGL rendering by the client. After all GLEventListeners have been notified of a display event, the drawable will swap its buffers if setAutoSwapBufferMode is enabled.

Specified by:

display in interface GLEventListener

dispose

public void dispose(GLAutoDrawable drawable)

Description copied from interface: GLEventListener

Notifies the listener to perform the release of all OpenGL resources per GLContext, such as memory buffers and GLSL programs.

Called by the drawable before the OpenGL context is destroyed by an external event, like a reconfiguration of the GLAutoDrawable closing an attached window, but also manually by calling destroy.

Note that this event does not imply the end of life of the application. It could be produced with a followup call to GLEventListener.init(GLAutoDrawable) in case the GLContext has been recreated, e.g. due to a pixel configuration change in a multihead environment.

Specified by:

dispose in interface GLEventListener

keyPressed

public void keyPressed(KeyEvent e)

Description copied from interface: KeyListener

A key has been pressed, excluding auto-repeat modifier keys. See KeyEvent.

Specified by:

keyPressed in interface KeyListener

keyReleased

public void keyReleased(KeyEvent e)

Description copied from interface: KeyListener

A key has been released, excluding auto-repeat modifier keys. See KeyEvent.

To simulated the removed keyTyped(KeyEvent e) semantics, simply apply the following constraints upfront and bail out if not matched, i.e.:

        if( !e.isPrintableKey() || e.isAutoRepeat() ) {
            return;
        }
