* app/*: chainsaw #include cleanup:
- Never (never!!) include stuff in header files except where we
need access to structures' contents (like derived objects).
- Added prototypes and proper formating in many files.
- The #include order in *all* *.c files is as follows:
#include "config.h"
#include <system stuff>
#include <gtk/gtk.h>
#include "apptypes.h"
#include "gimp stuff"
#include "libgimp stuff"
#include "libgimp/gimpintl.h"
By following this scheme we can easily see a file's dependencies
from it's #include's and can grep for the inclusion to find out
where a file is used.
* tools/pdbgen/app.pl: changed to follow the include scheme above.
* libgimp/Makefile.am
* libgimp/gimpuitypes.h: new file, included from libgimp/gimpui.h
and from app/apptypes.h.

* plug-ins/FractalExplorer/Dialogs.c
* plug-ins/gdyntext/message_window.c
* plug-ins/imagemap/imap_default_dialog.c
* plug-ins/imagemap/imap_file.c: these files used to include
"libgimp/gimpui.h" without including "libgimp/gimp.h". This is
no longer possible because the libgimpui headers don't inlcude
"libgimp/gimpunit.h" any more.

* app/cursorutil.[ch]: new cursor modifiers for bucket_fill.
* app/bucket_fill.c: use the new modifiers. Closes#17871.
* app/convolve.c
* app/dodgeburn.c: added cursor_update functions which update the
tools' "toggled" state before they call the cursor_update "method"
of the paint_core "class" -- eek -- I-want-real-objects!
Closes#17872 and #17873.
* app/tools.h: added SELECTION_ANCHOR to the SelectOps enum.
* app/free_select.c
* app/rect_select.c: use the new enum value in the "oper_update"
and "cursor_update" functions. In the "motion" function, set the
tool's operation type back to SELECTION_REPLACE if the tool is
active and call the "cursor_update" function explicitly.
Closes#17870.
* app/by_color_select.c: fixed warning caused by the new enum value.

2000-04-26 Michael Natterer <mitch@gimp.org>
* app/color_select.c
* app/colormaps.[ch]
* app/context_manager.c: removed unused global variables
[foreground|background]_pixel and [old|new]_color_pixel.
Initialize the colormap and visual stuff with GdkRGB instead of
GtkPreview functions (which are deprecated).
* app/[62 files]: removed #include's (started with colormaps.h and
couldn't stop). Also ordered them consistently and did some small
unrelated cleanups.
Removed variuos <stdlib.h> et.al. but checked the files carefully
before doing so. If I was too radical and you get warnings on your
platform, please flame me or just put them back :)
2000-04-20 Michael Natterer <mitch@gimp.org>
* app/fuzzy_select.c
* app/selection_options.h
* app/tool_options.c: moved the "Threshold" scale from the fuzzy
select options to the selection options structure, so none of the
selection tools needs it's own tools options structure.
* app/bucket_fill.c: moved "Threshold" after "Sample Merged" as in
the fuzzy select options.
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)?
2000-01-25 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.

* app/airbrush.c
* app/apptypes.h
* app/brushes_cmds.c
* tools/pdbgen/pdb/brushes.pdb
* app/bucket_fill.c
* app/clone.c
* app/gimpbrushpipe.c
* app/paint_core.c
* app/patterns.h
* app/patterns_cmds.c
* tools/pdbgen/pdb/patterns.pdb: removed the GimpBrushP and
GPatternP types and use ordinary pointers instead.
The following stuff makes the "no_data" behaviour consistent. As a
side-effect it should make the gimp work when there are _really_ no
brushes/patterns/gradients.
* app/brush_select.c
* app/pattern_select.c: set the initial brush/pattern name to "No
Brushes/Patterns available" instead of "Active".
* app/devices.c: set the device contexts' brush/pattern/gradient
names if we started with no_data, so we find them on refresh.
* app/gimpbrushlist.c: set the name of the standard_brush to
"Standard".
* app/gimpcontext.c: don't replace the current
brush/pattern/gradient's name if the new one to be set is the
standard one. Together with the change in devices.c, this ensures
that we get what is set in devicerc. Minor fixes.
* app/gradient.c: changed gradients_init() to work like the other
data init functions. Only insert a default gradient in the
gradients list when the editor is opened (this means that the
gradients now behave like brushes/patterns when we start with
"no_data").
New function gradient_update() avoids tons of useless redraws of
all clist gradient previews whenever the gradient editor wants to
update it's large preview.
* app/gradient_select.c: don't segfault when the user tries to
drag from an empty gradient list.
* app/patterns.c: set the index of the standard_pattern to -1 to
indicate that it's not part of the pattern list.
* app/app_procs.c: free the brush dialog before freeing the brushes.
* app/blend.c, app/bucket_fill.c: don't include brush_select.h
* app/brush_select.[ch]: add the ability to delete generated brushes.
* app/gimpbrushgenerated.c: save the brush parameters on seperate lines.
* app/gimpbrushlist.c: make sure we don't overwrite other brush
files when saving newly created brushes.
1999-08-23 Michael Natterer <mitschel@cs.tu-berlin.de>
* app/bucket_fill.[ch]: export bucket_fill_region().
* app/channels_dialog.c: enabled dropping a color to a channel.
* app/color_area.c
* app/color_panel.c
* app/gimpdnd.[ch]: the whole color dnd is now done in a generic
function in gimpdnd.c (dnd of other types is still hacked in at
various places but will go to generic functions and callbacks as
well).
* app/disp_callbacks.[ch]
* app/interface.c: drop a color to the display to bucket fill the
selected region.

* app/blend.c

* app/convolve.c
* app/dodgeburn.c
* app/eraser.c
* app/ink.c
* app/paintbrush.c
* app/pencil.c
* app/smudge.c: get opacity/paint mode from the current context
(currently always the user context).
* app/gimage_mask.c: the "stroke" command uses the paintbrush's
settings if the current context is the user context and we are in
per-tool paint options mode.
* app/context_manager.[ch]
* app/paint_options.h
* app/preferences_dialog.c
* app/tool_options.c
* app/tools.c: moved the global/per-tool paint options switching
to the context manager. The tool options themselves only contain
the widgets for them now. This should fix the segfaults happening
in per-tool mode.
Removed the disclaimer from the prefs. dlg. as it seems to work
now. The impl. in the context manager however is still a hack.
* app/brush_select.c
* app/brushes_cmds.c
* tools/pdbgen/pdb/brushes.pdb: same as above.
* app/lc_dialog.c: minimal code reduction. No functionality changed.
1999-07-02 Michael Natterer <mitschel@cs.tu-berlin.de>
* app/[all tools]: the Tool structure is now allocated by a common
constructor which sets default values and provides default tool
action functions. To get rid of much code duplication there should
be a object hierarchy of tools.
* app/context_manager.c
* app/tools.[ch]: create and destroy private contexts for the
paint tools on startup and exit. They are not used yet.
* app/interface.c
* app/menus.c
* app/tools.h: num_tools is now exported in tools.h
* app/commands.c
* app/gdisplay.c
* app/menus.c: made "Toggle Selection" a toggleable menu item.
1999-06-26 Michael Natterer <mitschel@cs.tu-berlin.de>
* app/[all tool related files]
* app/commands.c
* app/disp_callbacks.c
* app/gdisplay.c
* app/gimage.c
* app/interface.c: hopefully fixed the bugs that appeared with my
last fix. And some more changes...
- Slightly changed the conditions which cause the tools to be
re-initialized on button_press events and the global
initialisation functions.
- The dialog tools now explicitly set tool->gdisp_ptr so they can
be properly hidden on display deletion.
- Create the crop info dialog only once and avoid ugly redraw bugs
by blocking the sizeentries' signal when initializing them.
- Standardized the tools_new_<tool>() functions. They are
scheduled to be moved to a common constructor in tools.c
- Various stuff...
1999-06-21 Michael Natterer <mitschel@cs.tu-berlin.de>
* app/context_manager.c: namespace cleanups.
* app/commands.[ch]
* app/menus.c: moved the "Toggle Selection" menu entry to "View",
sprinkled some separators and made the layers/channels/paths popup
menus consistent with Tigert's last ops buttons change.
* app/fileops.c
* app/plug_in.c: check for gdisplay_active() returning NULL in
some more places.
* app/[all tool related files]:
- Turned the ToolAction and ToolState #define's into typedef'ed
enums, so the compiler can do some more sanity checking.
- Removed one more unused global variable "active_tool_layer".
- Removed some #include's from tools.c.
- Standardized the individual tools' structure names.
- Moved showing/hiding the tool options to separate functions.
- Stuff...
* app/commands.c
* app/disp_callbacks.c
* app/gdisplay.c
* app/tools.c: fixed the segfaults which happened when the image
of one of the tools which have dialogs (levels/posterize/...) was
deleted. My approach was to do stricter sanity checking and to set
some gdisplay pointers correctly where appropriate, so I can't
tell exactly where the bug was.
The curves tool now(??) updates on every _second_ display change
only, which is really obscure.
Finding/changing the display to operate on should definitely be
done by connecting to the user context's "display_changed"
signal.
* app/gimpset.c: emit the "remove" signal _after_ removing the
pointer from the set. If this was not a bug but a feature, please
let me know, we'll need two signals then.
worked here due to a bug in icewm. Should work much better now, also it still
isn't perfect (yet).
Had to change the standard toggle key for all toggleable tools to
<Ctrl> since <Shift> collides with line drawing in the Convolver tool.
--Sven
1999-04-24 Michael Natterer <mitschel@cs.tu-berlin.de>
* app/bucket_fill.c: added a "BG Color Fill" radio button.
Toggling FG/BG with <shift> works in both color fill modes now.
* app/brush_select.c: session management sets the size of the
dialog again (depending on the current paint options mode because
bad things happen if the brush preview's size is reduced beyond
it's minimum).
1999-04-22 Michael Natterer <mitschel@cs.tu-berlin.de>
First version of per-tool paint options. No PDB interface yet.
The tool options dialog got rather big when in per-tool mode, so
it will probably have to become a notebook.
It's not yet 100% consistent. If switched off, everything should
behave exactly like before.
* app/Makefile.am
* app/paint_options.h: new file
* app/tool_options.c: PaintOptions gui. Maintain a list of all
paint tools' ToolOptions to enable switching between global and
per-tool paint options.
* app/brush_select.[ch]: changed packing boxes, tables, ...
The paint options in the brush selection can be hidden now.
Moved create_paint_mode_menu() to paint_options.h and
tool_options.c and renamed it to paint_mode_menu_new().
* app/gimage_mask.c
* app/gimpbrush.[ch]
* app/gimpbrushlist.[ch]
* app/paint_core.c: moved gimp_brush_[set|get]_spacing() from
gimpbrushlist.[ch] to gimpbrush.[ch].
Moved gimp_brush_[get|set]_[opacity|paint_mode]() to
paint_options.h and tool_options.c and renamed them to
paint_options_*_*(). They are "global paint options" now.
* app/airbrush.c
* app/blend.c
* app/bucket_fill.c
* app/clone.c
* app/convolve.c
* app/eraser.c
* app/ink.c
* app/paintbrush.c
* app/pencil.c: all paint tools' options are derived from
"PaintOptions" now. Opacity and paint mode are obtained through
macros which take into account the current paint options mode.
* app/buildmenu.h: #include <gtk/gtk.h>
* app/color_picker.c
* app/text_tool.c: changed spacings.
* app/gimprc.[ch]: new gimprc option "global-paint-options"
* app/preferences_dialog.c: Added a "Tool Options" page. Code
cleanup. Some work on the convenience constructors test site.
* app/tools.c: fixed "unused variable" warning.
Tue Apr 20 23:38:26 BST 1999 Austin Donnelly <austin@gimp.org>
* app/bezier_select.c: add the new args to gimp-paintbrush PDB
calls.
* app/blend.c
* app/bucket_fill.c
* app/invert.c: check return from procedural_db_run_proc() rather
than dereferencing NULL.
* app/paintbrush.c: plumb the non-gui fade_out option into the
functions that actually do the work, rather than using
an uninitialised value.
* app/procedural_db.c: better error messages on PDB typecheck fail
in procedural_db_run_proc. Also now valid to
procedural_db_destroy_args() on a NULL pointer.
* app/procedural_db.h: pdb_type_name() function added, plus
comment urging people to keep the enum and strings in step.
* tools/pdbgen/README: added paragraph on how to run pdbgen.pl
* tools/pdbgen/pdb/tools.pdb: fade_out parameter is valid to be 0
* app/tools_cmds.c: new version of generated file
1999-04-18 Michael Natterer <mitschel@cs.tu-berlin.de>
* app/bucket_fill.c
* app/clone.c
* app/convolve.c
* app/flip_tool.c
* app/ink.c
* app/paintbrush.c
* app/transform_tool.c: remember all radio buttons in the
ToolOptions structures. This enables arbitrary default values and
gui feedback for the "toggle key" feature.

* app/Makefile.am
* app/tool_options.[ch]
* app/selection_options.h
* app/tool_options_ui.h: new files.
Ok, this time it's general enough for future extensions:
- The tool options structures are organized like the gtk object
system to allow derived tool options.
- Renamed all create and reset functions to *_options_new() and
*_options_reset() to reflect this.
- Changed tools_register() again. Now it takes just a pointer to a
ToolOptions structure.
- Moved almost the entire tool options gui code to tool_options.c.
- Visually separated the common selection options from the
tool-specific ones. I'd like to do the same with opacity/paint
mode in all paint tool options but I think this needs some more
discussion.
* app/histogram_tool.c: changed packing boxes, label alignments.
* app/paintbrush.c: some more sensitive settings. The gradient
feature can now be toggled with a button. Hopefully didn't break
anything.

Implemented the "reset tool options" feature.
- All tools register with a title string and a reset function now.
- The tool options' variables have two related <var>_d (default)
and <var>_w (widget) variables to restore the default values.
"Standardized" the tool options UI:
- Put the stuff info a frame to give a hint that the dialog's
contents will change.
- table layout, sensitive setting, spacings, borders, ...
As I had them all in my emacs simultaneously, I couldn't resist to
standardize the tools' *.c files declaration parts ;) Ansi stuff.

* i18n markings from Daniel Egger (mostly removal of tags around
PDB stuff), some constification
* I went on a sprintf pogrom. Use g_snprintf or g_strdup_printf
where applicable, to prevent overflows, especially with filenames
and translated strings. suid gimp is now more secure. ;)

Infrastructure to allow gimp dialogs to be controlled from plugins.
Brush dialog can now be invoked multiple times. Dialogs invoked
via plugins do not control the active brush (dialog only used for
selections).
New gimp_interactive_selection_brush() function to popup dialog
Example of usage in the gfig plugin.
Other dialogs should be able to use this method of invocation.
Started separating crud out of drawables.
Isolated the id system of images entirely within pdb. Even the
window titles and menus use pointers instead of ids. Should at
least remind people that this is a developers' version. :)
* redid the error message handling. g_message now calls message_box or prints
to console depending on whether the no_interface is set or not. gimp-message
is also exported to the PDB as a wrapper to g_message, and libgimp has a new
API: gimp_message. libgimp also overrides g_message for all plugins. Converted
lots of messages in app/* to g_message. Made script-fu a little friendlier.
* updated the regex code from grep 2.2
* said goodbye to the old script-fu logo in script-fu.h

* app/gimage.c
* app/tools.c
* app/tools.h: Added a field in the Tools struct, preserve.
During gimage_dirty, if this flag is not set the tool will be
reset. This is good for tools that keep a copy of the image
in cache for local manipulation like transform_core.
* app/bezier_select.c
* app/blend.c
* app/brightness_contrast.c
* app/bucket_fill.c
* app/color_balance.c
* app/color_picker.c
* app/crop.c
* app/curves.c
* app/ellipse_select.c
* app/free_select.c
* app/histogram_tool.c
* app/hue_saturation.c
* app/levels.c
* app/move.c
* app/paint_core.c
* app/posterize.c
* app/rect_select.c
* app/text_tool.c
* app/transform_core.c: Set the preserve flag to the correct
values in the new functions and wrapped calls to functions that
dirty the gimage to prevent tool restarts.
* app/disp_callbacks.c
* app/menus.c: Removed Nether's tool patch.
