Hi, This implements JTabbedPane and BasicArrowButton. Also many fixes. Cheers, Kim 2004-03-23 Kim Ho <kho@redhat.com> * Makefile.am: New file * Makefile.in: Regenerate * java/awt/Graphics.java: (drawRect): Draw to the correct point. * javax/swing/DefaultSingleSelectionModel.java (isSelected): Return true if the selected index is not -1. * javax/swing/JLabel.java: Do not change mnemonic index if text is null. * javax/swing/JProgressBar.java: Use JComponent's EventListenerList. * javax/swing/JScrollBar.java: Ditto. * javax/swing/JTabbedPane.java: Reimplement. * javax/swing/plaf/basic/BasicLookAndFeel.java: Add defaults for TabbedPane. * javax/swing/plaf/basic/BasicArrowButton.java: Implement * javax/swing/plaf/basic/BasicProgressBarUI.java: (paintDeterminate): Don't paint String if it's empty. (paintIndeterminate): ditto. * javax/swing/plaf/basic/BasicTabbedPaneUI.java: Reimplement.
