Example: I open a JFrame with a JButton inside that, when pressed, triggers the creation of a GLCanvas that is added to the frame's content pane. When the creation of the GLCanvas triggers a reshape (I call setSize), I get the following exception: net.java.games.jogl.GLException: Unable to lock surface (stack trace at end). A workaround that I found is to create a new thread in the actionPerformed of the button-listener (AWT thread), create the GLCanvas in the new thread, while the AWT thread is waiting for the new thread to finish. I've got a modifed gears demo that shows the issue. I'll try to attach it to this issue. --- The full stack trace --- net.java.games.jogl.GLException: Unable to lock surface at net.java.games.jogl.impl.windows.WindowsOnscreenGLContext.lockSurface(WindowsOnscreenGLContext.java:155) at net.java.games.jogl.impl.windows.WindowsOnscreenGLContext.makeCurrent(WindowsOnscreenGLContext.java:107) at net.java.games.jogl.impl.GLContext.invokeGL(GLContext.java:199) at net.java.games.jogl.GLCanvas.reshape(GLCanvas.java:105) at java.awt.Component.setBounds(Component.java:1664) at java.awt.Component.resize(Component.java:1601) at java.awt.Component.setSize(Component.java:1593) at Gears.startGears(Gears.java:74) at Gears$1.actionPerformed(Gears.java:46) at javax.swing.AbstractButton.fireActionPerformed(AbstractButton.java:1786) at javax.swing.AbstractButton$ForwardActionEvents.actionPerformed(AbstractButton.java:1839) at javax.swing.DefaultButtonModel.fireActionPerformed(DefaultButtonModel.java:420) at javax.swing.DefaultButtonModel.setPressed(DefaultButtonModel.java:258) at javax.swing.plaf.basic.BasicButtonListener.mouseReleased(BasicButtonListener.java:245) at java.awt.Component.processMouseEvent(Component.java:5100) at java.awt.Component.processEvent(Component.java:4897) at java.awt.Container.processEvent(Container.java:1569) at java.awt.Component.dispatchEventImpl(Component.java:3615) at java.awt.Container.dispatchEventImpl(Container.java:1627) at java.awt.Component.dispatchEvent(Component.java:3477) at java.awt.LightweightDispatcher.retargetMouseEvent(Container.java:3483) at java.awt.LightweightDispatcher.processMouseEvent(Container.java:3198) at java.awt.LightweightDispatcher.dispatchEvent(Container.java:3128) at java.awt.Container.dispatchEventImpl(Container.java:1613) at java.awt.Window.dispatchEventImpl(Window.java:1606) at java.awt.Component.dispatchEvent(Component.java:3477) at java.awt.EventQueue.dispatchEvent(EventQueue.java:456) at java.awt.EventDispatchThread.pumpOneEventForHierarchy(EventDispatchThread.java:201) at java.awt.EventDispatchThread.pumpEventsForHierarchy(EventDispatchThread.java:151) at java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:145) at java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:137) at java.awt.EventDispatchThread.run(EventDispatchThread.java:100) ---- Additional Comments From fsk456 2003-11-20 00:19:16 ---- Created an attachment Modified gears demo demonstrating issue (and new thread workaround) ---- Additional Comments From kbr 2005-01-30 23:51:07 ---- This issue has been fixed in one of the more recent JOGL builds.
