Method Summary

Modifier and Type	Method and Description
public void	display(GLAutoDrawable drawable) Called by the drawable to initiate OpenGL rendering by the client.
public void	dispose(GLAutoDrawable drawable) Notifies the listener to perform the release of all OpenGL resources per GLContext, such as memory buffers and GLSL programs.
public void	init(GLAutoDrawable drawable) Called by the drawable immediately after the OpenGL context is initialized.
public void	reshape(GLAutoDrawable the triggering `GLAutoDrawable` drawable, int viewport x-coord in pixel units x, int viewport y-coord in pixel units y, int viewport width in pixel units width, int viewport height in pixel units height) Called by the drawable during the first repaint after the component has been resized.

Method Detail

display	back to summary
public void display(GLAutoDrawable drawable) 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.

dispose back to summary

dispose	back to summary
public void dispose(GLAutoDrawable drawable) 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 `init(GLAutoDrawable)` in case the GLContext has been recreated, e.g. due to a pixel configuration change in a multihead environment.

public void dispose(GLAutoDrawable drawable)

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 init(GLAutoDrawable) in case the GLContext has been recreated, e.g. due to a pixel configuration change in a multihead environment.

init	back to summary
public void init(GLAutoDrawable drawable) 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.

public void init(GLAutoDrawable drawable)

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.

reshape	back to summary
public void reshape(GLAutoDrawable drawable, int x, int y, int width, int height) Called by the drawable during the first repaint after the component has been resized. The client can update it's viewport associated data and view volume of the window appropriately. For efficiency the GL viewport has already been updated via `glViewport(x, y, width, height)` when this method is called. Parameters drawable:GLAutoDrawable the triggering `GLAutoDrawable` x:int viewport x-coord in pixel units y:int viewport y-coord in pixel units width:int viewport width in pixel units height:int viewport height in pixel units

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

Called by the drawable during the first repaint after the component has been resized.

The client can update it's viewport associated data and view volume of the window appropriately.

For efficiency the GL viewport has already been updated via glViewport(x, y, width, height) when this method is called.

Parameters

drawable:GLAutoDrawable: the triggering GLAutoDrawable
x:int: viewport x-coord in pixel units
y:int: viewport y-coord in pixel units
width:int: viewport width in pixel units
height:int: viewport height in pixel units
