[Adrian Feiguin <feiguin magnet fsu edu>]

I am plased to announce the new release of GtkExtra
(http://magnet.fsu.edu/~feiguin/gtk) with the following changes.

19/04/2000 Summary of changes

GtkPlotCanvas
=============

Completely redesigned and re-written, almost from scratch, using the same API.
The new changes will make easier to add new objects in the future, like arrows.

- New structure GtkPlotCanvasItem:

  item->type                     item->data 
------------------------------------------------
GTK_PLOT_CANVAS_PLOT		 GtkPlot *
GTK_PLOT_CANVAS_TITLE		 GtkPlotAxis *
GTK_PLOT_CANVAS_AXIS		 GtkPlotAxis *
GTK_PLOT_CANVAS_LEGEND		 GtkPlot *
GTK_PLOT_CANVAS_TEXT		 GtkPlotText *

- Signals: "select_item", "move_item", "resize_item", "select_region"

- FLAGS: 
  GTK_PLOT_CANVAS_CAN_SELECT       allows to select a region,
                                   a simple box inside a plot.
  GTK_PLOT_CANVAS_CAN_SELECT_ITEM  allows to select objects, 
                                   but not datapoints. 
  GTK_PLOT_CANVAS_CAN_SELECT_POINT allows to select datapoints, 
                                   but not other objects. 
  GTK_PLOT_CANVAS_CAN_DND          allows to DnD objects, 
                                   once selected. 
  GTK_PLOT_CANVAS_CAN_DND_POINT    allows to DnD datapoints, 
                                   once selected. 

If you want to use DnD, you have to set both flags:
GTK_PLOT_CANVAS_CAN_SELECT_ITEM and GTK_PLOT_CANVAS_CAN_DND.
If you set only CAN_SETECT_ITEM, you won't be able to DnD.
If you set only CAN_DND, it won't work if CAN_SELECT_ITEM is off.
Same for datapoints.

You already know that if your signal handler returns the value FALSE,
the selection or action will be ignored.
