Description Sven Gothel 2010-03-24 07:45:44 CET


---- Reported by moussaba 2003-08-07 13:31:39 ----

When GLcanvas added to a JInternalFrame, when frame is iconized and restored it 
crashes and generates the following exception:

net.java.games.jogl.GLException: Error swapping buffers
	at 
net.java.games.jogl.impl.windows.WindowsOnscreenGLContext.swapBuffers
(WindowsOnscreenGLContext.java:137)
	at net.java.games.jogl.impl.GLContext.invokeGL(GLContext.java:187)
	at net.java.games.jogl.GLCanvas.displayImpl(GLCanvas.java:179)
	at net.java.games.jogl.GLCanvas.display(GLCanvas.java:84)
	at net.java.games.jogl.Animator$1.run(Animator.java:104)
	at java.lang.Thread.run(Thread.java:534)

Below is example source code that generates the exception

*
 * Lesson06.java
 * Modified on August 07, 2003
 * Reproduces the GLException: Error Swapping Buffers when
 * Using JInternalFrame.  Iconize the Internal Frame, restore it and you will
 * get the above mentioned exception.  This does not occur when the main window
 * is iconized.

Sorry for not investigating this bug until now. JOGL had proper
addNotify/removeNotify tracking added a while ago and the current JOGL source
runs the enclosed demo correctly. Please reopen this bug or file a new one if
you are still seeing problems.
