JOGL - GLJPanel 类
本章介绍如何使用 GLJpanel 类绘制 JOGL 基本框架。它是一个轻量级的 Swing 组件,提供 OpenGL 渲染支持。提供它是为了与 Swing 兼容。在这里,我们将实例化一个 JFrame 并使用add()方法将 GLJpanel 对象添加到 JFrame 的实例中。
以下程序使用带有 Swing 窗口的GLJPanel生成一个基本框架-
import javax.media.opengl.GLAutoDrawable;
import javax.media.opengl.GLCapabilities;
import javax.media.opengl.GLEventListener;
import javax.media.opengl.GLProfile;
import javax.media.opengl.awt.GLCanvas;
import javax.swing.JFrame;
public class BasicFrame implements GLEventListener {
@Override
public void display(GLAutoDrawable arg0) {
// method body
}
@Override
public void dispose(GLAutoDrawable arg0) {
//method body
}
@Override
public void init(GLAutoDrawable arg0) {
// method body
}
@Override
public void reshape(GLAutoDrawable arg0, int arg1, int arg2, int arg3, int arg4) {
// method body
}
public static void main(String[] args) {
//getting the capabilities object of GL2 profile
final GLProfile profile = GLProfile.get(GLProfile.GL2);
GLCapabilities capabilities = new GLCapabilities(profile);
// The GLJpanel class
GLJPanel gljpanel = new GLJPanel( glcapabilities );
BasicFrame b = new BasicFrame();
gljpanel.addGLEventListener(b);
gljpanel.setSize(400, 400);
//creating frame
final JFrame frame = new JFrame (" Basic Frame");
//adding canvas to it
frame.getContentPane().add( gljpanel);
frame.setSize(frame.getContentPane().getPreferredSize());
frame.setVisible(true);
}//end of main
}//end of classimport
如果编译并执行上述程序,将生成以下输出。它显示了当我们使用带有摆动窗口的GLJPanel时形成的基本框架-
