[gl4java-usergroup] Reshape method never called

[Jan F. <jan...@st...>]

Hi!

Why is my reshape method never called for this GLJPanel, even if the
window is resized?
I'm using GL4Java 2.5.0.

---------------------------------------------------

class GLScreen extends GLJPanel {
  public void init() {
    gl.glClearColor(0.0f, 0.0f, 0.0f, 0.0f);
    gl.glDisableClientState(GL_CULL_FACE);
    gl.glDisable(GL_DEPTH_TEST);
  }

  public void display() {
    gl.glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    gl.glMatrixMode(GL_MODELVIEW);
    gl.glLoadIdentity();

    gl.glBegin(GL_POLYGON);
      gl.glColor3d(1.0, 1.0, 1.0);
      gl.glVertex3d(-0.5, -0.5, 0.0);
      gl.glColor3d(0.0, 1.0, 1.0);
      gl.glVertex3d( 0.5, -0.5, 0.0);
      gl.glColor3d(1.0, 0.0, 0.0);
      gl.glVertex3d(0.0, 0.5, 0.0);
    gl.glEnd();
  }

  public void reshape(int width, int height) {
    gl.glViewport(0, 0, width - 1, height - 1);
    gl.glMatrixMode(GL_PROJECTION);
    gl.glLoadIdentity();
    if(width > height) {
      glu.gluOrtho2D(-(double)width/height, (double)width/height, -1.0,
1.0);
    } else {
      glu.gluOrtho2D(-1.0, 1.0, -(double)height/width,
(double)height/width);
    }
  }

  public GLScreen() {
    super();
  }
}

public class MainWindow extends JFrame implements ActionListener {

  public MainWindow() {
    Container content = getContentPane();
    GLScreen myGLScreen = new GLScreen();

    content.add("Center", myGLScreen);

    setSize(600, 500);
    setTitle("Simple Java OpenGL Application");
    setVisible(true);
  }

  public void actionPerformed(ActionEvent event) {
  }

  protected void processWindowEvent(WindowEvent event) {
    super.processWindowEvent(event);
    if (event.getID() == WindowEvent.WINDOW_CLOSING) {
      System.exit(0);
    }
  }

  public static void main(String[] args) {
    MainWindow theWindow = new MainWindow();
  }
}
