2004-01-20  Thomas Fitzsimmons  <fitzsim@redhat.com>

	* gnu/java/awt/peer/gtk/GtkTextFieldPeer.java,
	jni/gtk-peer/gnu_java_awt_peer_gtk_GtkTextFieldPeer.c
	(native create): Add width parameter.
	(create): Calculate text entry width based on current font's
	metrics and number of columns.  Set TextField's font if not
	already set.  Call native create.
	(gtkEntryGetBorderWidth): New native method.
	(gtkEntryGetSize): Remove method.
	(getMinimumSize): Call minimumSize.
	(getPreferredSize): Call preferredSize.
	(minimumSize): Calculate minimum size based on backing
	GtkEntry's borders, font metrics and number of columns.
	(preferredSize): Likewise for preferred size.
	(get_border_width): New static function.
