public void paint(final Graphics g)

Overrides java.awt.Canvas.paint.

Overridden to cause OpenGL rendering to be performed during repaint cycles. Subclasses which override this method must call super.paint() in their paint() method in order to function properly.

Parameters

public void removeNotify()

Overrides java.awt.Component.removeNotify.

Doc from java.awt.Component.removeNotify.

Makes this Component undisplayable by destroying it native screen resource.

This method is called by the toolkit internally and should not be called directly by programs. Code overriding this method should call super.removeNotify as the first line of the overriding method.
