It is on a JFrame in the center. In the WEST coord of the frame I have a panel with a single button. When I scroll my mouse onto and off of the JButton, it brieflly appears in the GL Context for some reason. Here is the test code public class Main { public Main(){ JFrame frame = new JFrame("Test Frame"); frame.setBounds(10, 10, 500, 500); frame.setLayout(new BorderLayout()); GLCapabilities glCaps = new GLCapabilities(); glCaps.setRedBits(8); glCaps.setBlueBits(8); glCaps.setGreenBits(8); glCaps.setAlphaBits(8); GLJPanel panel = GLDrawableFactory.getFactory().createGLJPanel(glCaps); frame.add(panel, BorderLayout.CENTER); JPanel p = new JPanel(new FlowLayout()); JButton b = new JButton("Test Me"); p.add(b); frame.add(p, BorderLayout.WEST); panel.addGLEventListener(new GLContextRenderer()); final Animator animator = new Animator(panel); frame.addWindowListener(new WindowAdapter() { public void windowClosing(WindowEvent e) { animator.stop(); System.exit(0); } }); frame.setVisible(true); animator.start(); } public static void main(String[] args) { new Main(); } } public class GLContextRenderer implements GLEventListener { GL gl; GLDrawable glDrawable; float xRot; public void init(GLDrawable glDrawable) { this.gl = glDrawable.getGL(); this.glDrawable = glDrawable; gl.glShadeModel(GL.GL_SMOOTH); // Enable Smooth Shading gl.glClearColor(0.0f, 0.0f, 0.0f, 0.5f); // Black Background gl.glClearDepth(1.0f); // Depth Buffer Setup gl.glEnable(GL.GL_DEPTH_TEST); // Enables Depth Testing gl.glDepthFunc(GL.GL_LEQUAL); // The Type Of Depth Testing To Do gl.glHint(GL.GL_PERSPECTIVE_CORRECTION_HINT, GL.GL_NICEST); // Really Nice Perspective Calculations gl.glEnable(GL.GL_TEXTURE_2D); } public void display(GLDrawable glDrawable) { gl.glClear(GL.GL_COLOR_BUFFER_BIT | GL.GL_DEPTH_BUFFER_BIT ); gl.glLoadIdentity(); gl.glTranslatef(0.0f, 0.0f, -6.0f); gl.glColor3f(1.0f, 0.0f, 0.0f ); gl.glRotatef(xRot, 1.0f, 0.0f, 0.0f); gl.glBegin( GL.GL_TRIANGLES ); gl.glVertex3f( 0.0f, 0.0f, 0.0f ); gl.glVertex3f( 1.0f, 0.0f, 0.0f ); gl.glVertex3f( 1.0f, 1.0f, 0.0f ); gl.glEnd(); xRot += .2f; } public void reshape(GLDrawable glDrawable, int x, int y, int width, int height) { final GLU glu = glDrawable.getGLU(); if (height <= 0) // avoid a divide by zero error! height = 1; final float h = (float)width / (float)height; gl.glViewport(0, 0, width, height); gl.glMatrixMode(GL.GL_PROJECTION); gl.glLoadIdentity(); glu.gluPerspective(45.0f, h, 1.0, 20.0); gl.glMatrixMode(GL.GL_MODELVIEW); gl.glLoadIdentity(); } public void displayChanged(GLDrawable glDrawable, boolean b, boolean b1) { //To change body of implemented methods use File | Settings | File Templates. } } ---- Additional Comments From kbr 2005-04-09 17:22:23 ---- Created an attachment Test case that works with 1.4.2 (click button to exhibit bug) ---- Additional Comments From kbr 2005-04-09 17:34:30 ---- The test case specifies alpha bits in the GLCapabilities, which caused the GLJPanel to create a TYPE_INT_ARGB BufferedImage to store the results of the readback of the frame buffer for rendering into the GLJPanel. This appears to not be the correct thing to do, because it causes this BufferedImage to be alpha-blended with whatever other rendering is performed into Java2D's backing store. Therefore when the button was redrawn, its image would show up in this backing store alpha-blended with the OpenGL rendering results since both were redrawn simultaneously. I believe the correct solution is to never create a BufferedImage with an alpha component for the framebuffer readback even if alpha bits are specified in the GLCapabilities. This is what has been implemented in the JOGL source base. --- Bug imported by sgothel@jausoft.com 2010-03-24 07:47 EDT --- This bug was previously known as _bug_ 148 at https://jogl.dev.java.net/bugs/show_bug.cgi?id=148 Imported an attachment (id=44) The original submitter of attachment 44 is unknown.
