(addNotify): Implemented. * java/awt/Rectangle.java (isEmpty): Fixed reversed logic. * java/awt/RenderingHints.java: New file. * java/awt/Toolkit.java (createComponent): Implemented. (getSystemEventQueue): Delegate to getSystemEventQueueImpl(). * java/awt/Window.java (Window): Two new constructors. Reordered constructor chaining. (getGraphicsConfigurationImpl): New method. (finalize): Call super. (addNotify): Call super. (pack): Do layout stuff. (show): Ensure that peer exists and that component is valid. (dispose): Dispose owned children. (getOwner): Simplify code, casting null pointers is valid. (getGraphicsConfiguration): Ask peer if local value is null. * java/awt/event/ActionEvent.java (getActionCommand): Renamed from getcmd(). * java/awt/image/BufferedImage.java: New file. * java/awt/image/RasterOp.java: New file. * java/awt/peer/ComponentPeer.java (getGraphicsConfiguration): More powerfull replacement for getColorModel(). (getColorModel) Removed. (setEventMask) New method. * Makefile.am: Added new files. * Makefile.in: Rebuilt. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@35748 138bc75d-0d04-0410-961f-82ee72b054a4 --- libjava/gnu/gcj/awt/ComponentDataBlitOp.java | 123 ++++++++++++++++++++++++ libjava/gnu/gcj/awt/GLightweightPeer.java | 134 +++++++++++++++++++++++++++ 2 files changed, 257 insertions(+) create mode 100644 libjava/gnu/gcj/awt/ComponentDataBlitOp.java create mode 100644 libjava/gnu/gcj/awt/GLightweightPeer.java (limited to 'libjava/gnu') diff --git a/libjava/gnu/gcj/awt/ComponentDataBlitOp.java b/libjava/gnu/gcj/awt/ComponentDataBlitOp.java new file mode 100644 index 00000000000..34861c65f1d --- /dev/null +++ b/libjava/gnu/gcj/awt/ComponentDataBlitOp.java @@ -0,0 +1,123 @@ +/* Copyright © 2000 Free Software Foundation + + This file is part of libgcj. + +This software is copyrighted work licensed under the terms of the +Libgcj License.
