* Port to gtk+-2                                                                               
* So many changes, it's hard to keep track of:
  - GtkArgs
  - widgetization of canvas items
  - dozens of fixes and improvements

2002-5-21 Patches by Michael S. Noble (mnoble@space.mit.edu)

*    gtkplotcanvas.c:

     Support the creation of polygon children, via


     These mirror similar functions for rectangles and ellipses, and
     so require points in canvas-space (not pixel- or data-space),
     only more of them.  The draw child code will automatically
     scale/move/etc the polygons when required.

*    The following functions were also added to gtkplotcanvas.c


     to permit language bindings to query the "current/active item" on
     the canvas, without referencing canvas/child struct internals.

*    gtkplot3d.c:
*    gtkplotsurface.c:

     Moved _sqrt() from gtkplot3d.c to gtkplotsurface.c.  It was referenced
     only in the latter file, but having it in the former could cause symbol
     referencing problems (an inlined static) with SparWorks 6.2 (cc
     version 5.3) on Solaris 8.

*    gtkplotps.c:  the inclusion

        #include <wctype.h>

    causes problems with gcc (GCC) 3.1 20020420 (prerelease) bundled with
    the Mac OS/X 10.2 developers toolkit (the file is missing).  Since none
    of the wide character functions from wctype.h are actually being used
    within gtkplotps.c, it was simply removed.

*   gtkplotdt.c: the inclusion

        #include <malloc.h>

    causes similar problems with gcc (GCC) 3.1 20020420 (prerelease) bundled
    with the Mac OS/X 10.2 developers toolkit (again, the file is missing).
    Since malloc.h is not a standard C header file (stdlib.h should be used
    instead), and none of the malloc.h functions are even being used in the

    source module, it was removed.

*   gtkextra.c:  At line 123 the statement

                gboolean *result = *(gboolean **)var_args;

    is unportable to platforms on which va_list is not a void* (e.g.,
    Compaq True64 Unix).  In correcting this problem the GValue collection
    logic was simplified.

    *** Of all the mods this one needs perhaps the most careful review. ***

*   gtkpsfont.c: There's no point in allowing gtk_psfont_unref() to drop
    refcount below zero.  It can cause spurious font init warnings later.

*   gtkplotdata.c: performance enhancement for spline connectors.

    Namely to precompute the number of points and alloate the spline array
    outside of the spline_eval loop.  This simplifies the code and avoids
    numerous repetition of trivial g_realloc(previous_size+2) calls.

    There are other instances in the code where this optimization can be
    applied.  The peformance hit becomes moe apparent when dataset sizes
    scale to 500,000+ points (even on my dual 2-Ghz cpu desktop).

2002-12-31  Toby D. Reeves  <toby@solidstatescientific.com>

       * docs/Makefile.am, gtkextra/Makefile.am : Ensured variables set with == before using +=.

       * gtkextra.spec.in : Make the rpm name a variable. Set rpm name to gtk+extra2
       allowing both 0.99.x and 1.1.x to be installed on same machine.

       * gtkextra/gtkplotcsurface.c : Changed function names to those found function prototypes.
       gtk_plot_csurface_get_level_attributes => gtk_plot_csurface_get_levels_attributes
       gtk_plot_csurface_set_level_attributes => gtk_plot_csurface_set_levels_attributes
       gtk_plot_csurface_get_sublevel_attributes => gtk_plot_csurface_get_sublevels_attributes
       gtk_plot_csurface_set_sublevel_attributes => gtk_plot_csurface_set_sublevels_attributes

2002-07-21  Allin Cottrell <cottrell@wfu.edu>

	- Fix breakage in application of earlier gtkiconfilesel patch

2002-07-18  Toby D. Reeves  <toby@solidstatescientific.com>

	* gtkextra.spec.in : Corrected %install to use DESTDIR.
	Make gtk+extra-devel package require gtk+extra.
	Added *.so to devel files.

	* gtkextra/Makefile.am : Added generated files 	gtkextratypebuiltins.[hc].
	Necessary for proper Python wrappers.
	* gtkextra/gtkextra.c : gtk_extra_check_version --to-- gtkextra_check_version
	* gtkextra/gtkextra.h : Commented addition of "#include <gtkextra/gtkextratypebuiltins.h>".
	Unless Makefile.am is changed to use stamp files, would cause massive
	code rebuilds to often.
	* gtkextra/gtkiconlist.h : Identified an anonymous enum that should be named. Did not know
	what developers might choose. Needed for proper Python wrappers.
	* gtkextra/gtkplotdt.c : gtk_plot_dt_set_quatrilateral --to-- gtk_plot_dt_set_quadrilateral

	* gtkextra/gtkplotdt.h : gtk_plot_dt_set_quadtrilateral --to-- gtk_plot_dt_set_quadrilateral

	* gtkextra/gtkpsfont.[hc] : changed return type of gtk_psfont_get_psfontname() to 
	"const gchar *" instead of "gchar *".
	* gtkextra/gtksheet.h : gtk_sheet_row_resizable --to-- gtk_sheet_rows_resizable

  gtk_signal_connect(GTK_OBJECT(axis), "tick_label", 
                     GTK_SIGNAL_FUNC(parse_tick_label), NULL);

  the return value is a string with the customized label generated in  
  "parse_tick_label", a function defined by the user

  Thanks to Alexander Haväng" <eel@musiknet.se> for the suggestion and
  the patches.

- gtk_plot_data_show/hide removed. We use gtk_widget_show/hide instead.

- All functions called ..._get_visible are now ..._visible 

21/11/2000 Summary of changes

 - New plot subclasses for 3D and polar plots: GtkPlot3d and GtkPlotPolar. 

   GtkPlot3D has its own API, but GtkPlotPolar can be casted as a GtkPlot 
 considering the equivalence x->r, y->angle.

 - GtkPlotData is a widget. The API is almost the same. You may have to
 cast the widget using data = GTK_PLOT_DATA(gtk_plot_data_new());

 - The other Data subclasses are Bar, Box, Flux, Surface and

 - I added new arguments to the datasets (z, dz, a, da): z is obviously for 
 3d plots. However, it is used in GtkPlotBox to specify the size of the boxes.
 "a" is used to determine the size of the symbols, and "da", the color.

 - The color of the symbols, when "da" is specified, is detemined using the
 gradient. the gradient has (min, max) values, and corresponding colors. The
 symbol's color is interpolated between these values using hue/saturation/value
 depending on the gradient_mask.

 - GtkOrientation was replaced with GtkPlotOrientation

 - the fields xticks and yticks were removed from gtkplot.

 - GtkPlotSymbol has a new field GtkPlotLine border and you set/get the
 attributes with gtk_plot_data_set/get_symbol

 - I removed the symbol type: GTK_PLOT_SYMBOL_BAR, because this is a new
 data subclass. I added TRIANGLE_LEFT/RIGHT and DOT.

 - After gtk_plot_canvas_paint, you have to use gtk_plot_canvas_refresh to
 refresh the pixmap in the window. This is because paint can be
 used to print or save plots in other formats, depending on the GtkPlotPC
 you are using (see below).

 - The drawing engine, called GtkPlotPC has been rewritten. Now
 it's a GtkObject, and you can derive subclasses as GtkPlotGdk and
 GtkPlotPS in our case (You can define your own if you want to use a
 different library to draw your plots!). 

 How does it work:
 1) Instead of creating a GdkGC, you create either a GtkPlotGdk or
 2) you do the following replacements:

 gdk_gc_set_foreground -> gtk_plot_pc_set_color
 gdk_gc_set_dash -> gtk_plot_pc_set_dash
 gdk_gc_set_line_attributes -> gtk_plot_pc_set_lineattr
 gdk_gc_draw_... -> gtk_plot_pc_draw_...

 The output will be either on a drawable or a file according to the
 GtkPlotPC you chose.

 All the redundant code for the PS output in gtkplotprint was eliminated!
 Elegant, isn't it?

 - I also added a new widget: gtktogglecombo, a gtkcombobox subclass (See it
 in action in testgtksheet)

 - New demos are included.

- Memory leaks fixed by Allin Cottrell <cottrell@wfu.edu>

12/06/2000 Summary of changes


- GtkPlotCanvasItem struct removed and replaced by GtkPlotCanvasChild

- New policy for handling canvas child objects:
  GtkPlotCanvas has a field GList *childs, replacing the old GList *text.
  Now, it can contain diferent kind of objects, like 

  These childs are predefined in the code, and you don't have to care about.
  You just use the new functions:

  I have included also the type GTK_PLOT_CANVAS_CUSTOM. It allows to
  define your custom childs, like the pixmap in testgtkplot.
  To do this, you should use

  child = gtk_plot_canvas_child_new(GTK_PLOT_CANVAS_CUSTOM);
  and define your drawing and printing routines and redirect as

  child->data = my_data;
  child->draw = my_drawing_code;
  child->print = my_printing_code;

  This should allow to insert images in the plots.
  By default, the child can only be moved. If you also want to allow to
  resize it, you should set the child->flags.
- You can use the following functions to set the childs' attributes

- I added guiding grids to the canvas. This grids can be displayed in the 
  canvas to guide the eyes, but they are not printed.

  To do so use:

- Signal handling for "select_item" has changed. Now the signal handler returns
  a GtkPlotCanvasChild struct. The contentd of the selection are in 
  child->data, and the type is declared in child->type. See the demo.

- gtk_plot_canvas_put_text has a new field "transparent". If TRUE, the text 
  background is not drawn.


- Silly bugfixes

- gtk_plot_put_text has a new field "transparent". If TRUE, the text 
  background is not drawn.


- New functions


- New handling to avoid memory leaks: 
  Every time you plan to use PSfonts you should initialize the tables and
  lists using gtk_psfont_init(); inmediately after gtk_init, or at the
  begining of a subroutine.
  At the end of the program or subroutine you should use gtk_psfont_unref();


- Changed to complain the new gtkpsfont concept.


- Bugfix in the size allocation routine.

08/05/2000 Summary of changes


- GtkPlotLayout was merged with GtkPlotCanvas and removed from the dirtribution.
  All the gtk_plot_layout... functions are now called gtk_plot_canvas...

- GtkPlotCanvas has been changed to be a GtkFixed subclass.

- gtk_plot_canvas_new has a new argument "magnification"

  With gtk_plot_canvas_set_magnification you can choose the page
  magnification. The page, and all the plots contained are rescaled.
  It's completely WYSIWYG. 


Removed from the distribution.


- All the functions "gtk_plot_dataset..." are now "gtk_plot_data..."

- Magnification

- Data labels: you can add individual labels to each point.

- New functions:
  gtk_plot_data_show/hide labels


- GtkIEntry is now called GtkItemEntry. 



- GtkIconList was changed to be a GtkFixed subclass. Much, much faster...
  GtkIconFileSelection is now very usable.

19/04/2000 Summary of changes


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 

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

  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:
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.
