From ffde862e033a0825e1e9972a89c0f1f80b261a8e Mon Sep 17 00:00:00 2001 From: mark Date: Mon, 14 Aug 2006 23:12:35 +0000 Subject: 2006-08-14 Mark Wielaard Imported GNU Classpath 0.92 * HACKING: Add more importing hints. Update automake version requirement. * configure.ac (gconf-peer): New enable AC argument. Add --disable-gconf-peer and --enable-default-preferences-peer to classpath configure when gconf is disabled. * scripts/makemake.tcl: Set gnu/java/util/prefs/gconf and gnu/java/awt/dnd/peer/gtk to bc. Classify gnu/java/security/Configuration.java as generated source file. * gnu/java/lang/management/VMGarbageCollectorMXBeanImpl.java, gnu/java/lang/management/VMMemoryPoolMXBeanImpl.java, gnu/java/lang/management/VMClassLoadingMXBeanImpl.java, gnu/java/lang/management/VMRuntimeMXBeanImpl.java, gnu/java/lang/management/VMMemoryManagerMXBeanImpl.java, gnu/java/lang/management/VMThreadMXBeanImpl.java, gnu/java/lang/management/VMMemoryMXBeanImpl.java, gnu/java/lang/management/VMCompilationMXBeanImpl.java: New VM stub classes. * java/lang/management/VMManagementFactory.java: Likewise. * java/net/VMURLConnection.java: Likewise. * gnu/java/nio/VMChannel.java: Likewise. * java/lang/Thread.java (getState): Add stub implementation. * java/lang/Class.java (isEnum): Likewise. * java/lang/Class.h (isEnum): Likewise. * gnu/awt/xlib/XToolkit.java (getClasspathTextLayoutPeer): Removed. * javax/naming/spi/NamingManager.java: New override for StackWalker functionality. * configure, sources.am, Makefile.in, gcj/Makefile.in, include/Makefile.in, testsuite/Makefile.in: Regenerated. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@116139 138bc75d-0d04-0410-961f-82ee72b054a4 --- .../classpath/java/awt/dnd/DragSourceContext.java | 191 +++++++++++++++++++-- 1 file changed, 172 insertions(+), 19 deletions(-) (limited to 'libjava/classpath/java/awt/dnd/DragSourceContext.java') diff --git a/libjava/classpath/java/awt/dnd/DragSourceContext.java b/libjava/classpath/java/awt/dnd/DragSourceContext.java index 88607b090ea..1fee5c0c304 100644 --- a/libjava/classpath/java/awt/dnd/DragSourceContext.java +++ b/libjava/classpath/java/awt/dnd/DragSourceContext.java @@ -70,8 +70,8 @@ public class DragSourceContext private Transferable transferable;
