Throws:

LWJGLException

AWTGLCanvas

public AWTGLCanvas(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(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.

Returns:

the Drawable's Context

createSharedContext

public org.lwjgl.opengl.Context createSharedContext()
                                             throws LWJGLException

This method should only be called internally.

Returns:

a Context shared with the Drawable's Context.

Throws:

LWJGLException

addNotify

public void addNotify()

Overrides:

addNotify in class Canvas

removeNotify

public void removeNotify()

Overrides:

removeNotify in class 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

isCurrent

public boolean isCurrent()
                  throws LWJGLException

Description copied from interface: Drawable

Returns true if the Drawable's context is current in the current thread.

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

releaseContext

public void releaseContext()
                    throws LWJGLException

Description copied from interface: Drawable

If the Drawable's context is current in the current thread, no context will be current after a call to this method.

Throws:

LWJGLException

destroy

public final void destroy()

Destroy the OpenGL context. This happens when the component becomes undisplayable

setCLSharingProperties

public final void setCLSharingProperties(PointerBuffer properties)
                                  throws LWJGLException

Description copied from interface: Drawable

Sets the appropriate khr_gl_sharing properties in the target PointerBuffer, so that if it is used in a clCreateContext(FromType) call, the created CL context will be sharing objects with this Drawable's GL context. After a call to this method, the target buffer position will have advanced by 2 to 4 positions, depending on the implementation.

Parameters:

properties - The target properties buffer. It must have at least 4 positions remaining.

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(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 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.
