MouseEvent

Olá pessoal,
Tenho uma classe que faz o Painel e nela te uma ação de Mouse que no método mouseClicked, cria um objeto da classe que é um OpenGL. Não consigo colocar de jeito nenhum a bendita janela do OpenGL no Painel.

Alguém me ajuda…

O erro:

Exception in thread “AWT-EventQueue-0” net.java.games.jogl.GLException: Unable to lock surface

O código:

public void mouseClicked(MouseEvent me)

{

if ( me.getSource() == JLabel_1 )

{

this.criaGraficoLinha();

}

}

E a classe do OpenGL:

public class GraficoLinha implements GLEventListener

{

public GLCanvas canvas = null;

public GraficoLinha()
{
	GLCapabilities capabilities = new GLCapabilities();
	capabilities.setHardwareAccelerated(true);
	capabilities.setDoubleBuffered(true);
	
	canvas = GLDrawableFactory.getFactory().createGLCanvas(capabilities);
	
	canvas.addGLEventListener(this);
	
	canvas.setSize(400, 300);
	canvas.setVisible(true);
}
public void init(GLDrawable glDrawable)
{
	GL myGL = glDrawable.getGL();
	myGL.glClearColor(1.0f, 1.0f, 1.0f, 0.0f);
	myGL.glShadeModel(GL.GL_FASTEST);
}
public void display(GLDrawable glDrawable)
{
	GL myGL = glDrawable.getGL();
	myGL.glClear(GL.GL_COLOR_BUFFER_BIT);
}
            public void reshape(GLDrawable glDrawable, int arg1, int arg2, int arg3, int arg4)
{
	GL myGL = glDrawable.getGL();
	int width = canvas.getWidth();
	int height = canvas.getHeight();
	
	// Define a transformacao WINDOW x VIEWPORT
	// Define a vizualização da VIEWPORT
	myGL.glViewport(0,0,width,height);
	myGL.glMatrixMode(GL.GL_PROJECTION);
	myGL.glLoadIdentity();
	// Define a visualização da WINDOW
	myGL.glOrtho(0,width,0,height,-10,0);
}	
public void displayChanged(GLDrawable glDrawable, boolean arg1, boolean arg2)
{
	
}

Alguém faz de um outro jeito me avisa por favor!
Abraçosss
