Handle GTK_FILE_CHOOSER_PROP_USE_PREVIEW_LABEL.

2004-02-29  Federico Mena Quintero  <federico@ximian.com>

	* gtk/gtkfilechooserdefault.c
	(gtk_file_chooser_default_set_property): Handle
	GTK_FILE_CHOOSER_PROP_USE_PREVIEW_LABEL.
	(gtk_file_chooser_default_get_property): Likewise.
	(struct _GtkFileChooserDefault): Added fields for preview_label,
	use_preview_label, preview_display_name, preview_box.  Removed
	preview_frame.
	(set_preview_widget): Reorder the widget in relation to the label.
	(update_preview_widget_visibility): Create or destroy the preview
	label.
	(check_preview_change): Update impl->preview_display_name and the
	label.
	(find_good_size_from_style): Use the preview_box.
	(gtk_file_chooser_default_finalize): Free
	impl->preview_display_name.
	(gtk_file_chooser_default_init): Initialize
	impl->use_preview_label.

	* gtk/gtkfilechooser.c (gtk_file_chooser_class_init): Add a
	"use-preview-label" property.
	(gtk_file_chooser_set_use_preview_label): New function.  This sets
	whether one wants the file chooser to display a stock label with
	the previewed filename.  Apps that do really fancy previews can
	turn this off and draw the name themselves.
	(gtk_file_chooser_get_use_preview_label): New function.
	(gtk_file_chooser_get_preview_widget_active): Documentation fix.

	* gtk/gtkfilechooserutils.h (GtkFileChooserProp): Add a
	GTK_FILE_CHOOSER_PROP_USE_PREVIEW_LABEL value.

	* gtk/gtkfilechooserutils.c
	(_gtk_file_chooser_install_properties): Override the
	"use-preview-label" property.
