public AWTGLCanvas()
            throws LWJGLException

Constructor using the default PixelFormat.

Throws:

LWJGLException

AWTGLCanvas

public AWTGLCanvas(PixelFormat pixel_format)
            throws LWJGLException

Create an AWTGLCanvas with the requested PixelFormat on the default GraphicsDevice.

Parameters:

pixel_format - The desired pixel format. May not be null

Throws:

LWJGLException

AWTGLCanvas

public AWTGLCanvas(java.awt.GraphicsDevice device,
                   PixelFormat pixel_format)
            throws LWJGLException

Parameters:

device - the device to create the canvas on.

pixel_format - The desired pixel format. May not be null

Throws:

LWJGLException

AWTGLCanvas

public AWTGLCanvas(java.awt.GraphicsDevice device,
                   PixelFormat pixel_format,
                   Drawable drawable)
            throws LWJGLException

Create an AWTGLCanvas with the requested PixelFormat on the specified GraphicsDevice.

Parameters:

device - the device to create the canvas on.

pixel_format - The desired pixel format. May not be null

drawable - The Drawable to share context with

Throws:

LWJGLException

AWTGLCanvas

public AWTGLCanvas(java.awt.GraphicsDevice device,
                   PixelFormat pixel_format,
                   Drawable drawable,
                   ContextAttribs attribs)
            throws LWJGLException

Create an AWTGLCanvas with the requested PixelFormat on the specified GraphicsDevice.

Parameters:

device - the device to create the canvas on.

pixel_format - The desired pixel format. May not be null

drawable - The Drawable to share context with

attribs - The ContextAttribs to use when creating the context. (optional, may be null)

Throws:

LWJGLException

Method Detail

getContext

public org.lwjgl.opengl.Context getContext()

This method should only be called internally.

Specified by:

getContext in interface Drawable

addNotify

public void addNotify()

Overrides:

addNotify in class java.awt.Canvas

removeNotify

public void removeNotify()

Overrides:

removeNotify in class java.awt.Component

setSwapInterval

public void setSwapInterval(int swap_interval)

Set swap interval.

setVSyncEnabled

public void setVSyncEnabled(boolean enabled)

Enable vsync

swapBuffers

public void swapBuffers()
                 throws LWJGLException

Swap the canvas' buffer

Throws:

LWJGLException

releaseContext

public void releaseContext()
                    throws LWJGLException

Throws:

LWJGLException

makeCurrent

public void makeCurrent()
                 throws LWJGLException

Make the canvas' context current. It is highly recommended that the context is only made current inside the AWT thread (for example in an overridden paintGL()).

Throws:

LWJGLException

initGL

protected void initGL()

Override this to do initialising of the context. It will be called once from paint(), immediately after the context is created and made current.

paintGL

protected void paintGL()

Override this to do painting

paint

public final void paint(java.awt.Graphics g)

The default paint() operation makes the context current and calls paintGL() which should be overridden to do GL operations.

Overrides:

paint in class java.awt.Canvas

exceptionOccurred

protected void exceptionOccurred(LWJGLException exception)

This method will be called if an unhandled LWJGLException occurs in paint(). Override this method to be notified of this.

Parameters:

exception - The exception that occurred.
