ComponentDataBlitOp.java: New file. * gnu/gcj/awt/ComponentDataBlitOp.java: New file. * gnu/gcj/awt/GLightweightPeer.java: New file. * java/awt/BorderLayout.java: Implemented all methods. * java/awt/Button.java (actionListener, actionCommand): Renamed and modifier change. (addNotify): Call super. (dispatchEventImpl): New method. (getListeners): New method. (label): Made package-private, not private. * java/awt/Canvas.java: Implemented class body. * java/awt/Color.java (brighter): New method. (darker): New method. (hashCode): New method. * java/awt/Component.java (visible, enabled, eventMask): Set defaults. (getGraphicsConfiguration): Delegate to getGraphicsConfigurationImpl(). (getGraphicsConfigurationImpl): New method. (getToolkit): Only return value from peer if not null. (isDisplayable): Check with parent. (isShowing): No parent implies not showing. (getForeground): Check parent property if local is null. (getBackground): Likewise. (getFont): Likewise. (setForeground): Inform peer. (setBackground): Likewise (setLocale): Invalidate component. (getColorModel): Implemented. (setLocation): Invalidate, or ignore if no change. (setSize): Invalidate, or ignore if no change. (setBounds): Invalidate, or ignore if no change. (isOpaque): By default, heavyweight implies opaque. (isLightweight): Implemented. (getMaximumSize): Implemented. (doLayout): Implemented, NOP. (validate): Implemented, NOP. (invalidate): Only propagate to parent if parent was valid. (getGraphics): Implemented. (getFontMetrics): Implemented. (update): Implemented. (paintAll): Implemented. (repaint): Implemented all repaint methods. (print): Implemented. (printAll): Implemented. (createImage): Implemented. (dispatchEvent): Give the peer a chance to handle the event. (dispatchEventImpl): Dispatch paint events. (enableEvents): Lightweights enable events on parent component. (coalesceEvents): Coalesce paint events, and select event type using a switch. (coalescePaintEvents): New method. (processEvent): Fix unfortunate ordering of statements, and call correct method for MOUSE_CLICKED. (processPaintEvent): New method. (addNotify): Allow container to notify children before event mask is set in peer. (addNotifyContainerChildren): New method. (removeNotify): Visibility should not change on removeNotify. (paramString): Implemented. (list): Implemented two of the list methods. * Container (myInsets): Removed, insets are managed by peer. (getInsets): Query peer. (addImpl): Fix reparenting, enable events for lightweights, initialize component array. (validate): Call doLayout in validateTree() instead. (validateTree): Do nothing if already valid. Call beginValidate(), endValidate() on peer. Call validateTree() instead of validate() for children that are containers. Mark valid after validation of children. (setFont): Partial implementation. (paint): Implemented. (visitChildren): New method. (visitChild): New method. (update): Implemented. (print): Implemented. (paintComponents): Implemented. (printComponents): Consider translation and clipping. (getComponentAt): Ignore invisible children. Return this if no child match. (addNotify): Call super. (addNotifyContainerChildren): New method. (paramString): Implemented. (list): Implemented. * java/awt/EventQueue (invokeAndWait): Get system event queue the right way. (invokeLater): Likewise. (isDispatchThread): Likewise. * java/awt/FontMetrics (getLeading): Formula change. (getDescent): Consider leading also. (getMaxAscent): Default to getAscent(). (getMaxDescent): Default to getDescent. (getMaxAdvance): Return value signifying unknown. (charWidth): Both methods implemented. (charsWidth): Implemented. (bytesWidth): Implemented. (getWidths): Implemented. * java/awt/Frame.java (NORMAL, ICONIFIED, iconImage, isResizable, state): New fields. (Frame): Rearragend constuctor chaining to disallow null being passed as a graphics configuration. (getTitle): Return empty string if null. (dispose): Removed. (getIconImage): New method. (setIconImage): New method. (finalize): New method. (setMenuBar): Notify peer. (isResizable): New method. (setResizable): New method. (getState): New method. (getFont): Removed. (remove): Implemented. (removeNotify): New method. (getFrames): New method. * java/awt/Graphics.java: Implemented body of class. * java/awt/Graphics2D.java: New file. * java/awt/GraphicsConfiguration.java: Enabled part of the API. * java/awt/Image.java: Implemented body of class. * java/awt/Panel.java (Panel): Call correct super constructor. (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. From-SVN: r35748
