the pref's cursor menu are still dummys.
2000-05-21 Michael Natterer <mitch@gimp.org>
These changes enable help support for 3rd party plug-ins which
install their help files outside GIMP's main help dir.
Instead of calling gimp_help(), gimp_plugin_help_func() etc.,
all help callbacks now have to call gimp_standard_help_func()
which has different implementations in the app and in libgimp.
There is a new function gimp_plugin_help_register() which can
be called during plug-in query. plug_in.c keeps a list of
executable_name/help_path pairs. Plug-ins have to pass their
exec. name to gimp_help() which uses the list to find the plug-in's
help directory.
* app/gimphelp.[ch]: gimp_help() now takes a help_path parameter.
help_path == NULL means the standard help directory. Various
changes to pass the help_path to the help browser.
* app/gimprc.c: save the plug-in's help_path in the pluginrc file.
* app/menus.c: ugly hack to enable help_paths in the "F1" callback.
* app/plug_in.[ch]: many help_path related changes. Use g_basename()
instead of strrchr(str,G_DIR_SEPARATOR), cosmetic cleanups.
* app/internal_procs.c
* app/gimphelp_cmds.c
* tools/pdbgen/pdb/gimphelp.pdb: new procedure
gimp_plugin_help_register(). gimp_help() takes a second parameter
which is the executable name (not the help_path).
* app/color_notebook.c
* app/commands.c
* app/lc_dialog.c
* app/preferences_dialog.c
* app/tools.c: call gimp_standard_help_func() instead of gimp_help().
* libgimp/gimp.c: new function gimp_get_progname() which returns
the full path of the plug-in's executable.
* libgimp/gimp.h: export the new function,
removed gimp_plugin_help_func(), gimp_help() takes the executable
name as second parameter.
* libgimp/gimpcompat.h: added gimp_plugin_help_func().
* libgimp/gimphelp.c: a wrapper for gimp_plugin_help_register(),
changed the calls to gimp_help.
* libgimp/gimphelpui.[ch]: call gimp_standard_help_func() instead
of gimp_help().
* plug-ins/helpbrowser/helpbrowser.c: now called with an additional
help_path parameter. Various changes to enable
help_path != gimp_standard_help_path.
Unrelated stuff:
* app/batch.h: added missing GPL header.
* app/gimpunit.c: had a LGPL header, merged some fprintf's into
one call.
* app/procedural_db.[ch]: cosmetic: g* types, s/g_malloc/g_new/,
prototypes, indentation.
* app/resize.c: use less packing widgets. didn't find the "offset"
redraw bug :(
2000-05-20 Sven Neumann <sven@gimp.org>
* plug-ins/webbrowser/web-browser.scm: added links to
Carey Bunks's "Gimp-Savvy" and "Grokking the GIMP" resources.
* libgimp/gimpwidgets.[ch]: use unsigned integers for the
memsize_entry. Added gimp_uint_adjustment_update().
* gimprc.[ch]
* preferences_dialog.c: use unsigned integers for memsizes
(tile_cache_size and max_new_image_size). Allows to set those
values up to 4GB. Fixes bug #11053.
2000-04-30 Michael Natterer <mitch@gimp.org>
* gimprc.in
* app/gimprc.[ch]: replaced "color-cube" by "min-colors".
* app/app_procs.c: read unitrc/gimprc before displaying the splash.
* app/colormaps.c: set min_colors and install_cmap before
initializing GdkRGB.
* app/gimprc.[ch]
* app/gimpunit.c: don't call the splash's progress_update function.
* app/plug_in.c: pass min_colors instead of color_cube to plugins.
* app/preferences_dialog.c: widget for min_colors.
* libgimp/gimp.[ch]: s/color_cube/min_colors/ but left
gimp_color_cube() there for source level compatibility.
* libgimp/gimpprotocol.[ch]: changed the GPConfig message
accordinly and increased the gimp protocol version number because
the change breaks binary compatibility. Also actually pass the
use_xshm variable over the wire (was only in the GPConfig struct
before).
Was it the right thing to do to increase the version number??
* libgimp/gimpui.c (gimp_ui_init): use the same code as the app
for initializing GdkRGB. Never explicitly activate Gdk's SHM
usage (only switch it off).
* app/main.c
* libgimp/gimp.c: reverted the handling of all signals except
SIGCHLD back to plain old signal() because those signals are
fatal anyway and sigaction() as used by gimp_signal_*() made
debugging (stacktrace) impossible.

2000-04-19 Michael Natterer <mitch@gimp.org>
* app/bucket_fill.c
* app/by_color_select.c
* app/fuzzy_select.c
* app/preferences_dialog.c: made the "default_threshold" gimprc
variable work as advertized:
- initialize the thresholds with it.
- use it for "Reset".
- added a widget to the "Tool Options" preferences page.
- noticed that the "Reset" button of "By Color Select" doesn't
behave like all the other "Reset" buttons and changed it to
reset the ui, not the selection.
(There is now a "None" button and because it was so trivial, I
couldn't resist to add "All" and "Invert" buttons, too)
* libgimp/Makefile.am
* libgimp/gimpui.c: new file.
* libgimp/gimpui.h: new function gimp_ui_init() which will be
called by all plugins which have a ui (not only by those with a
preview because plugins should always follow gimp's colormap
installation policy).
Could someone please check if the FIXME stuff in the function
is the right thing to do (TM). Does GdkRGB allocate the correct
colors for the widgets in all cases or do we have to find another
way to ensure this across processes (gtk instances)?
2000-02-14 Michael Natterer <mitch@gimp.org>
* app/preferences_dialog.c: purely cosmetic.
* libgimp/gimpdialog.c: purely fanatic.
* libgimp/gimpwidgets.c: attach label, scale and spinbutton to the
adjustment returned by gimp_scale_entry_new().
* plug-ins/common/film.c: set reasonable climb_rate's for the
advanced options's spinbuttons.
2000-02-07 Michael Natterer <mitch@gimp.org>
* app/*
* libgimp/*
* plug-ins/*
* tools/pdbgen/*: did a global s/GUnit/GimpUnit/ and
s/GimpSizeEntryUP/GimpSizeEntryUpdatePolicy/
* libgimp/gimpcolorspace.c: renamed the parameter names to match
the names in the header.
* libgimp/gimphelpui.h
* libgimp/gimpimage.c
* libgimp/gimpmatrix.h
* libgimp/gimpsizeentry.[ch]
* libgimp/gimpsizeentry.[ch]
* libgimp/gimpunit.[ch]
* libgimp/gimpunitmenu.[ch]
* libgimp/gimpwidgets.[ch]: added documentation and use g* types
all over the place (enables cross-referencing with the glib and
gtk+ html documentation).
* plug-ins/common/exchange.c
* plug-ins/common/max_rgb.c: small cleanups.
* plug-ins/common/mapcolor.c: the color buttons were attached in
the wrong order.
2000-02-05 Tor Lillqvist <tml@iki.fi>
* gimprc.in: user_install creates the gflare directory as
"gflares" (not "gflare"), so use that form here, too.
* gimprc.win32: Update to match the Unix version.
* app/ops_buttons.c: Include gimpintl.h.
* app/preferences_dialog.c (file_pref_cmd_callback): I18n for the
Pixels/%s string. It used to come out as "Pixels/tuuma" in
Finnish, for instance.
* plug-ins/gflare/gflare.c: Portability.
* libgimp/gimpui.def:
* plug-ins/makefile.{cygwin,msc}
* modules/makefile.{cygwin,msc}: Updates.
2000-02-01 Michael Natterer <mitch@gimp.org>
* app/preferences_dialog.c: applied a (modified) patch from Daniel
which removes the useles word "Settings" from the prefs. dialog.
2000-02-01 Michael Natterer <mitch@gimp.org>
* libgimp/gimpwidgets.[ch]: merged the table attach helper
functions into one function.
* app/*
* plug-ins/*: changed the calls to gimp_table_attach_aligned()
accordingly. Did minimal ui updates (spacing and stuff) in some
files.
2000-01-28 Michael Natterer <mitch@gimp.org>
* libgimp/gimpwidgets.[ch]: added one more option menu constructor
and made the namespace more consistent, minor fixes.
* libgimp/gimpdialog.c
* libgimp/gimpunitmenu.c: minor fixes.
* app/preferences_dialog.c
* plug-ins/borderaverage/borderaverage.c
* plug-ins/common/gif.c
* plug-ins/common/randomize.c: changed according to the above
namespace cleanups.
2000-01-26 Michael Natterer <mitch@gimp.org>
* app/preferences_dialog.c: forgot to correctly set the
tile_cache_size. Only apply show_tool_tips and tile_cache_size if
the prefs settings are not currupt.
2000-01-26 Michael Natterer <mitch@gimp.org>
* app/preferences_dialog.c: made the handling of the values which
can't be changed on the fly consistent:
- Some of the widget callbacks were connected to gimprc variables
instead of pref dialog's "edit_" variables.
- Correctly assign value, edit_value, old_value and save_value for
all of them.
- Separated them from the other values in all functions.
- Reduced the endless "if" madness in some callbacks.
2000-01-26 Michael Natterer <mitch@gimp.org>
* app/preferences_dialog.c: use the int adjustment callback from
libgimp, simplified the confirm dialog signal callbacks.
2000-01-25 Michael Natterer <mitch@gimp.org>
* app/appenv.h: removed BOUNDS, MINIMUM and MAXIMUM. No need to
include both <glib.h> and <gtk/gtk.h>.
* app/*
* tools/pdbgen/pdb/text_tool.pdb: s/BOUNDS/CLAMP/,
same for MIN and MAX.
* app/preferences_dialog.c: the "Check Size" widget was connected
to the transparency_type variable.
* plug-ins/common/sobel.c: removed definitions of MIN and ROUND.
* libgimp/gimp.h: #include "gimplimits.h" and "gimpcolorspace.h".
* plug-ins/*: don't include the two files.
2000-01-13 Michael Natterer <mitch@gimp.org>
* app/gimpui.[ch]
* app/preferences_dialog.c: removed & renamed some functions from
gimpui.[ch] (see below).
* libgimp/Makefile.am
* libgimp/gimpwidgets.[ch]; new files. Functions moved from
app/gimpui.[ch]. Added a constructor for the label + hscale +
entry combination used in many plugins (now hscale + spinbutton).
* libgimp/gimpui.h: include gimpwidgets.h
* plug-ins/megawidget/megawidget.[ch]: removed all functions
except the preview stuff (I'm not yet sure how to implement this
in libgimp because the libgimp preview should be general enough to
replace all the other plugin previews, too).
* plug-ins/borderaverage/Makefile.am
* plug-ins/borderaverage/borderaverage.c

1999-12-19 Michael Natterer <mitch@gimp.org>
* gimprc.in
* app/gimprc.[ch]
* app/preferences_dialog.c: new gimprc variable "help-browser"
which can be either "gimp", or "netscape".
* app/gimphelp.[ch]: depending on the value of help_browser, show
the help page with the webbrowser plugin.
1999-12-18 Michael Natterer <mitch@gimp.org>
* app/preferences_dialog.c: Added a special help function which
shows the help for the active notebook page.

* app/gimprc.c
* app/gimprc.h
* app/info_window.c
* app/info_window.h
* app/preferences_dialog.c
* app/undo_history.c
Info dialog now has option to follow the mouse movements or
the old behaviour of one dialog per display.
This dialog still needs some work.
Undo dialog now obeys the "tab" key in the display.
1999-11-27 Michael Natterer <mitch@gimp.org>
* app/main.c: bind the "gimp-perl" textdomain.
* app/menus.c: try to find a plugin's name in the "gimp-perl"
domain if searching in "gimp-std-plugins" fails.
* app/preferences_dialog.c: factored out a small frame+vbox
creation function from the huge dialog constructor and did some
small changes. Didn't change the logic.
1999-11-20 Michael Natterer <mitch@gimp.org>
* app/preferences_dialog.c: new prefs. page "Help System" because
there will soon be more widgets there (browser selection etc.)
Cleaned up the "Display" and "Interface" pages a bit.
* app/menus.c
* plug-ins/common/plugindetails.c: add "...".
* libgimp/gimpfileselection.c
* libgimp/gimppatheditor.c: a widget shouldn't connect to it's own
"realize" signal. Set widget_class->realize = <widget>_realize
instead.
2nd Try.. First failed due to problems at my end....
Sat Nov 20 00:27:26 GMT 1999 Andy Thomas <alt@gimp.org>
* app/commands.c
* app/gdisplay.c
* app/gimprc.c
* app/gimprc.h
* app/nav_window.c
* app/nav_window.h
* app/preferences_dialog.c
* app/scale.c
* app/scroll.c
Nav dialog now follows auto. There is an option in the
preferences dialog (interface) that allow you to switch
between this behaviour and the "original" way of having
one nav dialog per display.
1999-11-03 Michael Natterer <mitch@gimp.org>
* app/brush_select.[ch]
* app/gradient.c
* app/gradient_select.[ch]
* app/interface.[ch]
* app/palette.c
* app/pattern_select.[ch]: allow dragging a brush/pattern/... from
the selections with mouse2 without changing the active element in
the dialog.
* app/channels_dialog.c

* app/color_panel.c

* app/layers_dialog.c
* app/lc_dialog.c
* app/ops_buttons.[ch]
* app/paths_dialog.c
* app/preferences_dialog.c
* app/tools.[ch]: wrapped gtk_tooltips_set_tip() with
gimp_help_set_help_data() and moved it to gimphelp.[ch].
This should (hopefully) be the final state of the help system. The
New function allows a "private tip" to be set without a visible
tooltip. This way the tooltips inspector (shift+F1) can search for
help data in the parent containers of the clicked widget. E.g. the
ops buttons in the layers dialog have private tips like
"#new_layer" which gets composed with the help data of the layers
dialog notebook page resulting in a complete help path.
Allow mouse2 for all dnd operations. Mouse1 still works like before.
1999-10-03 Michael Natterer <mitch@gimp.org>
The GIMP Help System part II: press "F1" while browsing a menu
to show the help page for the menu entry you're currently over
with the mouse.
* app/color_notebook.c: all color selectors have to register with
a help page now.
* app/color_select.[ch]: register with a help string. Removed
the dialog part of the files because it's use was deprecated
anyway (use color notebooks instead).
* app/colormap_dialog.i.c
* app/colormap_dialog.p.h
* app/palette.c
* app/palette_select.c: use a color notebook instead of a color
selector.
* app/gimphelp.c
* app/gimpui.c: minor changes.
* app/gimprc.c: "use help" defaults to TRUE now.
* app/lc_dialog.c
* app/lc_dialogP.h: a special help function which shows the help
for the currently selected notebook page.
* app/menus.c: some weird code which catches "key_press_event"
in all menu shells and pops up the corresp. help page for the
selected item. Embedded the GtkItemFactoryEntry in a new
GimpItemFactoryEntry to allow a help path to be stored.
Will be partially exported and moved to gimphelp.[ch] later to
catch key_press for plug-in menu items (don't try this now ;-)

The GIMP Help System part 1: Press "F1" in any dialog to pop up
the help page for this dialog.
Moved the widget constructors from preferences_dialog.[ch] and the
query boxes from interface.[ch] to gimpui.[ch].
The dialog constructors take a help_func and a help_data
parameter and install the "F1" accelerator which emits the new
"help" signal.
The "help" signal callback calls help_func(help_data) which finally
has to call gimp_help() which in turn invokes the help browser.
Still have to find a proper way to (1) prevent "F1" being assigned
to some menu item and (2) to catch "F1" while browsing the menu
trees in order to pop up the help for the selected item.
* app/menus.c: a <Toolbox>/File/Help... menu item.
* app/commands.[ch]: a command callback for the "Help..." menu item.
* app/gimprc.[ch]: new boolean gimprc variable "use_help".
* app/info_dialog.[ch]: pass a help function and data to the info
dialog constructor.
* app/tools.[ch]: store the tools help page names in the tool info
structure. Export a special tools_help_func() which shows the help
page for the active tool.
* app/[all files calling a dialog constructor]: pass the dialog's
help page to the constructor.
Most dialogs are now created by gimp_dialog_new() which also sets
up the action_area and the WM delete event callback, so I removed
the resp. code from these files.
Fixed some minor bugs and did some other stuff but didn't change
any logic except dialog creation.
* plug-ins/helpbrowser/helpbrowser.c: don't try to call a running
help browser and don't install any menu path (all done in
app/gimphelp.[ch] now).
