Similar to JFrame's closing behavior, the following components window closing follow the new WindowClosingProtocol: - GLCanvas - GLJPanel - NEWT Window, GLWindow - NEWT NewtCanvasAWT
The implementation obeys either 1) the user value set by this interface, 2) an underlying toolkit set user value (JFrame, ..) 3) or it's default, eg. {@link #DO_NOTHING_ON_CLOSE DO_NOTHING_ON_CLOSE} within an AWT environment.
If none of the above determines the operation, this protocol default behavior {@link #DISPOSE_ON_CLOSE DISPOSE_ON_CLOSE} shall be used.
