本章介绍如何使用Canvas和javax.swing 包中的JFrame类绘制 JOGL 基本框架。在这里,我们将实例化一个 JFrame 并使用add()方法将画布对象添加到 JFrame 的实例中。
将 Canvas 与 AWT 结合使用可为您提供具有重量级功能的图形框架。为了拥有一个轻量级的图形框架,您需要将GLCanvas与 Swing 结合使用。在 Swing 中使用GLCanvas时,您可以将GLCanvas直接放置在JFrame窗口中,也可以将其添加到JPanel中。
下面给出的是结合 JOGL 的GLCanvas类和javax.swing包的JFrame类创建 JOGL 基本框架的程序。
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 canvas final GLCanvas glcanvas = new GLCanvas(capabilities); BasicFrame b = new BasicFrame(); glcanvas.addGLEventListener(b); glcanvas.setSize(400, 400); //creating frame final JFrame frame = new JFrame (" Basic Frame"); //adding canvas to it frame.getContentPane().add(glcanvas); 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。它显示了我们使用GLCanvas和 Swing 窗口时形成的基本框架。
