Question

J'écris mon premier programme opengl et je veux en cliquant sur la souris la couleur de ma forme est changée, mais cela ne fonctionne pas. c'est mon code .... quelle est ma faute?

float red = 1.0f, green = 1.0f, blue = 1.0f; 
public void init(GLAutoDrawable drawable) 
{ 
    GL2 gl=drawable.getGL().getGL2(); 
    gl.glClearColor(0.0f,0.0f,0.0f,0.0f); 
} 
public void display(GLAutoDrawable drawable) 
{ 
    GL2 gl=drawable.getGL().getGL2(); 
    gl.glClear(GL2.GL_COLOR_BUFFER_BIT); 
    gl.glColor3f (red, green, blue); 

    gl.glBegin(GL2.GL_LINES); 
    gl.glVertex3f(0.5f,0.5f,0.1f); 
    gl.glVertex3f(-0.5f,-0.5f,0.0f);
