2003-02-18  Hans Boehm  <Hans.Boehm@hp.com>

	* gnu/awt/xlib/XToolkit.java (getFontMetrics): initialize
	if necessary.

	* gnu/java/awt/peer/gtk/GtkButtonPeer.java,
	gnu/java/awt/peer/gtk/GtkTextAreaPeer.java,
	gnu/java/awt/peer/gtk/GtkTextFieldPeer.java,
	jni/gtk-peer/gnu_java_awt_peer_gtk_GtkButtonPeer.c,

	jni/gtk-peer/gnu_java_awt_peer_gtk_GtkTextFieldPeer.c
	(setFont, gtkSetFont): add.
	gnu/java/awt/peer/gtk/GtkComponentPeer.java (GtkComponentPeer):
	Propagate font to peer.  (setFont): add FIXME comment.

	* jni/gtk-peer/gnu_java_awt_peer_gtk_GtkTextAreaPeer.c
	(gtkTextGetSize): fix height, width computation.

	* gnu/java/awt/peer/gtk/GtkFontPeer.java (GtkFontPeer):
	Make X font name a bit less bogus.

	* jni/gtk-peer/gnu_java_awt_peer_gtk_GtkScrollBarPeer.c
	(post_adjustment_event): Pass on GTK_SCROLL_NONE.

	* java/awt/Scrollbar.java (setValues): Fix visibleAmount range check.
	(processAdjustmentEvent): Adjust value.

	* java/awt/FlowLayout.java (layoutContainer) Fix 2 indexing and one
	logic errors.

	* java/awt/Component.java (setVisible, show, hide): Call show and
	hide methods in subclasses.
	(getPreferredSize): don't set prefSize before we have peer.

	* java/awt/TextArea.java, java/awt/TextField.java (getPreferredSize):
	Guess (0,0) if we don't have peer.
