From ae9a0d04fb865aecbec78b821e1d89d5e59a5437 Mon Sep 17 00:00:00 2001 From: Kenneth Russel Date: Sun, 5 Feb 2006 18:09:26 +0000 Subject: Intermediate checkin for FBO support in Java2D/JOGL bridge. Needed to keep track of server-side OpenGL objects, like textures and display lists, created by the end user to preserve the illusion of independent contexts even though they will all share textures and display lists with the Java2D OpenGL context in order to access its FBO. Added GLObjectTracker class to track creation and destruction of these objects and to support cleanup when the last referring context has been destroyed. Modified GLContextShareSet to create and install GLObjectTrackers when necessary and GLContext to ref and unref tracker appropriately. Changed GlueGen's JavaPrologue and JavaEpilogue directives (and their documentation) to perform argument name substitution. Wrote documentation section on argument name substitution and specified behavior for primitive arrays (converts to string "array_name, array_name_offset" in substitution). Rephrased GlueGen's RangeCheck directives in terms of JavaPrologue directives and deleted old specialized code. Fixed bug in handling of VBO support in GLConfiguration when JavaPrologue was present for affected functions. Added JavaPrologue and JavaEpilogue directives to all existing OpenGL routines creating server-side objects (though it's possible some were missed) to call GLObjectTracker when necessary. Added RangeCheck directives for these routines as well. Worked around bug in JOGL demos where shutdownDemo() was being called more than once. git-svn-id: file:///usr/local/projects/SUN/JOGL/git-svn/../svn-server-sync/jogl-demos/trunk@172 3298f667-5e0e-4b4a-8ed4-a3559d26a5f4 --- src/gleem/ExaminerViewer.java | 10 ++++++---- 1 file changed, 6 insertions(+), 4 deletions(-) (limited to 'src') diff --git a/src/gleem/ExaminerViewer.java b/src/gleem/ExaminerViewer.java index 7c2d39f..a7f3d64 100644 --- a/src/gleem/ExaminerViewer.java +++ b/src/gleem/ExaminerViewer.java @@ -338,10 +338,12 @@ public class ExaminerViewer { } private void removeListeners() { - window.removeMouseMotionListener(mouseMotionListener); - window.removeMouseListener(mouseListener); - window.removeGLEventListener(glListener); - ManipManager.getManipManager().setupMouseListeners(window); + if (window != null) { + window.removeMouseMotionListener(mouseMotionListener); + window.removeMouseListener(mouseListener); + window.removeGLEventListener(glListener); + ManipManager.getManipManager().setupMouseListeners(window); + } } private void passiveMotionMethod(MouseEvent e) { -- cgit v1.2.3
