        btnTabSil.addActionListener(new ActionListener() {
            public void actionPerformed(ActionEvent arg0) {


                TestFrame.this.getPanel1().removeAll();
                Activator.graphPanel.revalidate();

                 // where it throws the exception is below
                TestFrame.this.getPanel1().add(Activator.graphPanel);
                TestFrame.this.revalidate();
                TestFrame.this.repaint();
                TestFrame.this.setVisible(true);
            }
        });
    }
    return btn;
}

}

在上面的激活器类中，我将 (JPanel) graphpanel添加到 (JPannel) testFrame.getPanel1()然后使用 testFrame 类中的一个按钮，我使用removeAll()方法并再次添加静态 graphPannel，但出现以下错误。

当我调试它时，我看到 GLcanvas 失去了 peer。我找不到解决方案。

请切换到 JOGL 2.3.1。然后，将“javax.media”替换为“com.jogamp”以避免任何编译错误。

当您从其父容器中删除 AWT GLCanvas 时，它会失去它的对等体并且它的 OpenGL 上下文被破坏。这是使用这种画布时无法避免的。如果这不是所需的行为，请切换到 NEWT。

在某些特定情况下，在某些硬件上创建另一个上下文可能会失败。如果您仍然使用最新版本的 JOGL 获得相同的堆栈跟踪，请填写错误报告：http: //jogamp.org/wiki/index.php/Jogl_FAQ#Bugreports_.26_Testing
