javax.media.opengl.awt.GLJPanel
public class GLJPanel
A lightweight Swing component which provides OpenGL rendering support. Provided for compatibility with Swing user interfaces when adding a heavyweight doesn't work either because of Z-ordering or LayoutManager problems.
The GLJPanel can be made transparent by creating it with a
GLCapabilities object with alpha bits specified and calling setOpaque(boolean)(false). Pixels with resulting OpenGL alpha values less
than 1.0 will be overlaid on any underlying Swing rendering.
Notes specific to the Reference Implementation: This component
attempts to use hardware-accelerated rendering via pbuffers and
falls back on to software rendering if problems occur.
Note that because this component attempts to use pbuffers for
rendering, and because pbuffers can not be resized, somewhat
surprising behavior may occur during resize operations; the GLEventListener.init(javax.media.opengl.GLAutoDrawable) method may be called multiple times as the
pbuffer is resized to be able to cover the size of the GLJPanel.
This behavior is correct, as the textures and display lists for
the GLJPanel will have been lost during the resize operation. The
application should attempt to make its GLEventListener.init()
methods as side-effect-free as possible.
Please read Java2D OpenGL Remarks.

public final Object getUpstreamWidget()
GLAutoDrawableGLAutoDrawable instance, if exist.
Currently known Java UI toolkits and it's known return types are:

This method may also return null if no UI toolkit is being used,
as common for offscreen rendering.
getUpstreamWidget in interface GLAutoDrawablepublic void display()
GLAutoDrawableCauses OpenGL rendering to be performed for this GLAutoDrawable in the following order:
display(..) for all
registered GLEventListeners. GLRunnable,
enqueued via GLAutoDrawable.invoke(boolean, GLRunnable).
May be called periodically by a running GLAnimatorControl implementation,
which must register itself with GLAutoDrawable.setAnimator(javax.media.opengl.GLAnimatorControl).
Called automatically by the window system toolkit upon receiving a repaint() request,
except an GLAnimatorControl implementation GLAnimatorControl.isAnimating().
This routine may also be called manually for better control over the
rendering process. It is legal to call another GLAutoDrawable's
display method from within the display(..) callback.
In case of a new generated OpenGL context,
the implementation shall call init(..) for all
registered GLEventListeners before making the
actual display(..) calls,
in case this has not been done yet.

GLAutoDrawablelistener to the end of this drawable queue.
The listeners are notified of events in the order of the queue.
The newly added listener's init(..)
method will be called once before any other of it's callback methods.
See GLAutoDrawable.getGLEventListenerInitState(GLEventListener) for details.

IndexOutOfBoundsException - If the index is not within (0 <= index && index < size()), or -1public boolean getGLEventListenerInitState(GLEventListener listener)
GLAutoDrawablelistener is initialized or not.
After adding a GLEventListener it is
marked uninitialized and added to a list of to be initialized GLEventListener.
If such uninitialized GLEventListener's handler methods (reshape, display)
are about to be invoked, it's init(..) method is invoked first.
Afterwards the GLEventListener is marked initialized
and removed from the list of to be initialized GLEventListener.
This methods returns the GLEventListener initialized state,
i.e. returns false if it is included in the list of to be initialized GLEventListener,
otherwise true.
getGLEventListenerInitState in interface GLAutoDrawablelistener - the GLEventListener object to query it's initialized state.
public void setGLEventListenerInitState(GLEventListener listener,
boolean initialized)
GLAutoDrawablelistener's initialized state.
This methods allows manually setting the GLEventListener initialized state,
i.e. adding it to, or removing it from the list of to be initialized GLEventListener.
See GLAutoDrawable.getGLEventListenerInitState(GLEventListener) for details.
Warning: This method does not validate whether the given listener's
is member of this drawable queue, i.e. added.
This method is only exposed to allow users full control over the GLEventListener's state
and is usually not recommended to change.
One use case is moving a GLContext and their initialized GLEventListener
from one GLAutoDrawable to another,
where a subsequent init(..) call after adding it
to the new owner is neither required nor desired.
See swapGLContextAndAllGLEventListener(..).
setGLEventListenerInitState in interface GLAutoDrawablelistener - the GLEventListener object to perform a state change.initialized - if true, mark the listener initialized, otherwise uninitialized.
public GLEventListener disposeGLEventListener(GLEventListener listener,
boolean remove)
GLAutoDrawablelistener via dispose(..)
if it has been initialized and added to this queue.
If remove is true, the GLEventListener is removed from this drawable queue before disposal,
otherwise marked uninitialized.
If an GLAnimatorControl is being attached and the current thread is different
than the animator's thread, it is paused during the operation.
Note that this is an expensive operation, since dispose(..)
is decorated by GLContext.makeCurrent() and GLContext.release().
Use removeGLEventListener(listener) instead
if you just want to remove the listener and don't care about the disposal of the it's (OpenGL) resources.
Also note that this is done from within a particular drawable's
GLEventListener handler (reshape, display, etc.), that it is not
guaranteed that all other listeners will be evaluated properly
during this update cycle.
disposeGLEventListener in interface GLAutoDrawablelistener - The GLEventListener object to be disposed and removed if remove is trueremove - pass true to have the listener removed from this drawable queue, otherwise pass false
public GLEventListener removeGLEventListener(GLEventListener listener)
GLAutoDrawablelistener from this drawable queue.
This is an inexpensive operation, since the removed listener's
dispose(..) method will not be called.
Use disposeGLEventListener(listener, true)
instead to ensure disposal of the listener's (OpenGL) resources.
Note that if this is done from within a particular drawable's
GLEventListener handler (reshape, display, etc.), that it is not
guaranteed that all other listeners will be evaluated properly
during this update cycle.

public void setAnimator(GLAnimatorControl animatorControl)
GLAutoDrawable
Registers the usage of an animator, an GLAnimatorControl implementation.
The animator will be queried whether it's animating, ie periodically issuing GLAutoDrawable.display() calls or not.
This method shall be called by an animator implementation only,
e.g. AnimatorBase.add(javax.media.opengl.GLAutoDrawable), passing it's control implementation,
and AnimatorBase.remove(javax.media.opengl.GLAutoDrawable), passing null.
Impacts GLAutoDrawable.display() and GLAutoDrawable.invoke(boolean, GLRunnable) semantics.

GLAutoDrawableGLRunnable,
which will be executed within the next GLAutoDrawable.display() call
after all registered GLEventListeners

methods has been called.
If no GLAnimatorControl is animating (default),
or if the current thread is the animator thread,
a GLAutoDrawable.display() call is issued after enqueue the GLRunnable,
hence the GLRunnable will be executed right away.
If an animator is running,
no explicit GLAutoDrawable.display() call is issued, allowing the animator to perform it when it's due.
If wait is true the call blocks until the glRunnable
has been executed by the animator, otherwise the method returns immediately.
If wait is true and
GLDrawable.isRealized() returns false or GLAutoDrawable.getContext() returns null,
the call is ignored and returns false.
This helps avoiding deadlocking the caller.
The internal queue of GLRunnable's is being flushed with GLAutoDrawable.destroy()
where all blocked callers are being notified.

GLAutoDrawable
The GLContext share need not be associated with this
GLDrawable and may be null if sharing of display lists and other
objects is not desired. See the note in the overview
documentation on
context sharing.
This GLAutoDrawable implementation holds it's own GLContext reference,
thus created a GLContext using this methods won't replace it implicitly.
To replace or set this GLAutoDrawable's GLContext you need to call GLAutoDrawable.setContext(GLContext).
The GLAutoDrawable implementation shall also set the
context creation flags as customized w/ GLAutoDrawable.setContextCreationFlags(int).
createContext in interface GLAutoDrawablecreateContext in interface GLDrawablepublic void setRealized(boolean realized)
GLDrawablesetRealized on a GLCanvas, a GLJPanel, or a
GLPbuffer, as these perform the appropriate calls on their
underlying GLDrawables internally.
Developers implementing new OpenGL components for various window
toolkits need to call this method against GLDrawables obtained
from the GLDrawableFactory via the GLDrawableFactory.getGLDrawable() method. It must typically be
called with an argument of true when the component
associated with the GLDrawable is realized and with an argument
of false just before the component is unrealized.
For the AWT, this means calling setRealized(true) in
the addNotify method and with an argument of
false in the removeNotify method.
GLDrawable implementations should handle multiple
cycles of setRealized(true) /
setRealized(false) calls. Most, if not all, Java
window toolkits have a persistent object associated with a given
component, regardless of whether that component is currently
realized. The GLDrawable object associated with a
particular component is intended to be similarly persistent. A
GLDrawable is intended to be created for a given
component when it is constructed and live as long as that
component. setRealized allows the
GLDrawable to re-initialize and destroy any
associated resources as the component becomes realized and
unrealized, respectively.
With an argument of true,
the minimum implementation shall call
NativeSurface's lockSurface() and if successfull:
GLCapabilities, which are associated with
the attached NativeSurface's AbstractGraphicsConfiguration.NativeSurface's unlockSurface().NativeSurface's lockSurface()
ensures resolving the window/surface handles, and the drawable's GLCapabilities
might have changed.
Calling this method has no other effects. For example, if
removeNotify is called on a Canvas implementation
for which a GLDrawable has been created, it is also necessary to
destroy all OpenGL contexts associated with that GLDrawable. This
is not done automatically by the implementation.

isRealized in interface GLDrawablepublic GLContext setContext(GLContext newCtx)
GLAutoDrawablenewCtx.setGLDrawable(drawable, true);.
drawable might be an inner GLDrawable instance if using a delegation pattern,
or this GLAutoDrawable instance.
If the old or new context was current on this thread, it is being released before switching the drawable. The new context will be made current afterwards, if it was current before. However the user shall take extra care that no other thread attempts to make this context current.
Be aware that the old context is still bound to the drawable, and that one context can only be bound to one drawable at one time!
In case you do not intend to use the old context anymore, i.e. not assigning it to another drawable, it shall be destroyed before setting the new context, i.e.:
GLContext oldCtx = glad.getContext();
if(null != oldCtx) {
oldCtx.destroy();
}
glad.setContext(newCtx);
This is required, since a context must have a valid drawable at all times
and this API shall not restrict the user in any way.

If this method is called outside of the GLEventListener's callback methods (init, display, etc.) it may
return null. Users should not rely on the identity of the
returned GL object; for example, users should not maintain a
hash table with the GL object as the key. Additionally, the GL
object should not be cached in client code, but should be
re-fetched from the GLAutoDrawable at the beginning of each call
to init, display, etc.

GLAutoDrawableGL pipeline object this GLAutoDrawable uses.
This should only be called from within the GLEventListener's

implementations currently expect the GLJPanel to be completely
cleared (e.g., by glClear(GL_COLOR_BUFFER_BIT |

implementations which use OpenGL internally, it may be possible
to perform OpenGL rendering using the GLJPanel into the same
OpenGL drawable as the Swing implementation uses.
