2001-02-07 Michael Natterer <mitch@gimp.org>
* app/Makefile.am
* app/gimpimagepreview.[ch]: new object with own implementations
of "create_preview" and "create_popup".
* app/gimpdrawablepreview.c: stuff... still unused.
* app/gimppreview.c: fixed idle rendering crashes, don't
forget popups on GDK_2BUTTON_PRESS.
* app/app_procs.c: gimpbrushlist.h doesn't exist any more.
* app/gimpobject.h: removed the GimpObject typedef because it
is in apptypes.h
2001-01-24 Michael Natterer <mitch@gimp.org>
* Makefile.am
* configure.in
* gimptool.in: added the new library below.
* libgimpwidgets/Makefile.am
* libgimpwidgets/gimpchainbutton.[ch]
* libgimpwidgets/gimpcolorarea.[ch]
* libgimpwidgets/gimpcolorbutton.[ch]
* libgimpwidgets/gimpdialog.[ch]
* libgimpwidgets/gimpfileselection.[ch]
* libgimpwidgets/gimphelpui.[ch]
* libgimpwidgets/gimppatheditor.[ch]
* libgimpwidgets/gimppixmap.[ch]
* libgimpwidgets/gimpquerybox.[ch]
* libgimpwidgets/gimpsizeentry.[ch]
* libgimpwidgets/gimpunitmenu.[ch]
* libgimpwidgets/gimpwidgets.[ch]
* libgimpwidgets/gimpwidgets.def
* libgimpwidgets/gimpwidgetstypes.h: new shared library.
Currently there are some ugly dependencies into libgimp. These
will be removed and go to a "libgimpglue" library which will be
a library for functions which share a common interface between
plug-ins and the app but have different implementations.
Include "libgimp/gimpunit.h" from "libgimpwidgets/gimpwidgetstypes.h"
to simulate this upcoming separation.
* libgimp/Makefile.am
* libgimp/gimpchainbutton.[ch]
* libgimp/gimpcolorarea.[ch]
* libgimp/gimpcolorbutton.[ch]
* libgimp/gimpdialog.[ch]
* libgimp/gimpfileselection.[ch]
* libgimp/gimphelpui.[ch]
* libgimp/gimppatheditor.[ch]
* libgimp/gimppixmap.[ch]
* libgimp/gimpquerybox.[ch]
* libgimp/gimpsizeentry.[ch]
* libgimp/gimpunitmenu.[ch]
* libgimp/gimpwidgets.[ch]: removed from here.
* libgimp/gimpui.h
* libgimp/gimpuitypes.h
* libgimp/makefile.mingw.in
* libgimp/makefile.msc: changed accordingly.
* app/[all ui files]
* app/pdb/palette_cmds.c
* app/pdb/tools_cmds.c
* tools/pdbgen/pdb/palette.pdb
* tools/pdbgen/pdb/tools.pdb: #include "libgimpwidgets/gimpwidgets.h"
and removed useless includes.
* app/apptypes.h: #include "libgimpwidgets/gimpwidgetstypes.h"
* app/Makefile.am
* plug-ins/[all makefiles which link against libgimpui]:
link against libgimpwidgets.la
* po-libgimp/POTFILES.in: changed file locations.
2001-01-22 Michael Natterer <mitch@gimp.org>
* app/Makefile.am
* app/toolbox.[ch]: new files containing most of the code
from app/interface.[ch]
* app/interface.[ch]: only contains create_display_shell() now.
Needs to be somehow merged with other arbitrarily named display
files around.
* app/app_procs.c
* app/menus.c
* po/POTFILES.in: changed accordingly.
* app/asupsample.c
* app/gradient.c
* app/tile.c: cleanup.
2000-12-29 Michael Natterer <mitch@gimp.org>
* app/Makefile.am
* app/channel_pvt.h
* app/drawable_pvt.h
* app/gdisplayF.h
* app/gimpdrawableP.h
* app/gimpimageP.h
* app/layer_pvt.h
* app/toolsF.h: removed these files.
* app/apptypes.h
* tools/pdbgen/enums.pl: added tons of opaque typedefs and enums.
* tools/pdbgen/pdb/brush_select.pdb
* tools/pdbgen/pdb/brushes.pdb
* tools/pdbgen/pdb/channel.pdb
* tools/pdbgen/pdb/color.pdb
* tools/pdbgen/pdb/convert.pdb
* tools/pdbgen/pdb/display.pdb
* tools/pdbgen/pdb/drawable.pdb
* tools/pdbgen/pdb/fileops.pdb

* tools/pdbgen/pdb/image.pdb
* tools/pdbgen/pdb/layer.pdb
* tools/pdbgen/pdb/pattern_select.pdb
* tools/pdbgen/pdb/patterns.pdb
* tools/pdbgen/pdb/selection.pdb
* tools/pdbgen/pdb/tools.pdb
* 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.
* libgimp/gimpcolorbutton.[ch]
* libgimp/gimpdialog.[ch]
* libgimp/gimphelpui.[ch]
* libgimp/gimpparasite.[ch]
* libgimp/gimppatheditor.[ch]
* libgimp/gimpprotocol.c
* libgimp/gimpquerybox.[ch]
* libgimp/gimpsizeentry.[ch]
* libgimp/gimptypes.h
* libgimp/gimpui.h
* libgimp/gimpunit.h
* libgimp/gimpunitmenu.[ch]
* libgimp/gimpwidgets.[ch]: changed accordingly.
* 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.
2000-11-08 Michael Natterer <mitch@gimp.org>
* Makefile.am
* gimp.spec.in
* user_install
* gtkrc_user: new file gtkrc_user which gets installed as
~/.gimp-1-1/gtkrc (We used to parse the same file twice if the
user didn't the change user-specific gtkrc. The new file has
comments only).
* app/app_procs.c: g_free() the user gtkrc filename after use.
* libgimp/gimpui.c: parse the user gtkrc here too.
2000-11-03 Sven Neumann <sven@gimp.org>
* app/app_procs.c (app_init): parse the users gtkrc as found in
~/.gimp-1.1 after the systemwide gtkrc has been parsed.
* user_install.bat: reverted Tor's change since we use the file
again now.
2000-08-09 Michael Natterer <mitch@gimp.org>
* app/app_procs.c: make_initialization_status_window(): reverse
logic for if(!no_interface && !no_splash)
* app/palette.[ch]: removed declarations of the two removed
functions. One more s/gint/gboolean/.
* libgimp/gimpfileselection.[ch]
* libgimp/gimppixmap.[ch]: some consistency fixes (mostly fanatic :)
* libgimp/gimpproceduraldb.c: fixed a compiler warning.
2000-05-07 Michael Natterer <mitch@gimp.org>
* app/app_procs.c
* app/docindex.[ch]: named all public functions document_index_*().
Don't loop/segfault when opening an old "ideas" file but silently
skip the first line.
* app/fileops.[ch]: do some file access sanity checks before
actually calling the load/save proc. Show the full file name
in all error messages. Use a query_boolean_box for the overwrite
warning. Made file_save() static.
Also copied some Win32 #define's from libgimp/gimpenv.c for the
file access stuff. Tor, could you have a look at them please?
2000-05-06 Michael Natterer <mitch@gimp.org>
* po/POTFILES.in
* app/Makefile.am
* app/docindexif.[ch]: removed because it was not doing core/ui
separation at all. UI functions were randomly scattered across
both files.
* app/app_procs.c
* app/docindex.[ch]: swallow all functions from docindex.c,
removed functions which were called just once, replaced the
tree by a list. Actually raise displays of already open images.
When opening a file which is already in the list, move it's entry
to the top; this way the toolbox' last_opened list finally works
as expected.
2000-05-05 Michael Natterer <mitch@gimp.org>
Made the document index a bit more like the rest of the dialogs:
* app/commands.[ch]
* app/menus.c: added a cmd_callback instead of calling a function
in docindex.c directly.
* app/gimprc.c
* app/session.[ch]: added proper session management.
* app/app_procs.c
* app/docindex.[ch]
* app/docindexif.[ch]: removed another bunch of useless variables
and functions. Removed the status bar because it was not telling
very useful stuff. Removed the window position/size from the
"ideas" file.
Note: you have to either remove your ~/.gimp-1.1/ideas file or
remove it's first line or experience a nice endless loop :)
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.
* plug-ins/AlienMap/AlienMap.c

* plug-ins/xjt/xjt.c: use gimp_ui_init().
* plug-ins/Lighting/lighting_ui.c
* plug-ins/MapObject/mapobject_ui.c: only switch Gdk SHM usage off,
never on. Don't use gimp_ui_init() here because of libgck.
* app/app_procs.c: if we cannot load the font we'd like to use,
use the gtk+ default font. Fixes bug #8359.
* app/about_dialog.c
* app/install.c: properly ref/unref fonts
* app/text_tool.[ch]: code cleanup (do not rely on TRUE being 1)
* app/tips_dialog.c: code cleanup and less resizing
--Sven
2000-03-24 Michael Natterer <mitch@gimp.org>
* Makefile.am
* gimp1_0_splash.ppm: added
* gimp1_1_splash.ppm: removed
* gimp_splash.ppm: the image formerly known as gimp1_1_splash.ppm
* app/app_procs.c: load gimp_splash.ppm
The idea if shearing the data_dir between Gimp versions has
vanished, so this seems like the right thing to do (TM).
Keep the 1.0 splash around for sentimental reasons but don't
install it anymore.
* plug-ins/common/autocrop.c: indentation paranoia.
2000-02-22 Michael Natterer <mitch@gimp.org>
* app/gimpcontext.[ch]: it's more intelligent to implement the
parent_context stuff with gtk_signal_connect_object() instead of
having internal callbacks for each context attribute.
Exported the existing gimp_context_*_changed() functions and
changed them to do nothing but emitting the signal.
* app/app_procs.c
* app/tools.c
* app/transform_tool.c: use gimp_context_tool_changed() instead of
gtk_signal_emit_by_name().
2000-02-12 Michael Natterer <mitch@gimp.org>
* app/app_procs.c: fix a warning.
* app/menus.c: don't allow the help menu item accelerators to be
changed. Move all ordinary menu items under "<Toolbox>/Xtns"
before the separator without explicitly naming them.
* app/session.[ch]: minor cleanups without changing any logic.
2000-02-10 Michael Natterer <mitch@gimp.org>
* libgimp/gimpquerybox.[ch]: as all boolean query boxes are
confirmations for deleting/closing something, I added the "eek"
wilber (you can still disable the pixmap by passing FALSE to the
constructor's "eek" parameter).
* app/app_procs.c
* app/gdisplay_ops.c
* app/gradient.c
* app/palette.c
* plug-ins/gflare/gflare.c: pass eek==TRUE to the boolean query
box constructor.
2000-02-10 Michael Natterer <mitch@gimp.org>
* Makefile.am
* pixmaps/wilber.xpm: new file.
* libgimp/gimpdialog.[ch]: uncommented some lines. Depending on
your window manager, you'll figure out what it does without having
to look at the sources...
* app/app_procs.c
* app/gradient.c
* app/menus.c: minor changes to bring the goodie above to all
places. Did dome cleanups.
* app/commands.c: I18N fix.
* app/channels_dialog.c: removed an unused declaration.
2000-01-06 Tor Lillqvist <tml@iki.fi>
* app/app_procs.c (make_initialization_status_window): Finetune
the max_label_length hack, to avoid the splash screen's width
wobbling (on Win32).
* PLUGIN_MAINTAINERS: Added myself as maintainer of gpb, winprint,
winsnap, and wmf.
1999-12-17 Michael Natterer <mitch@gimp.org>
* app/app_procs.c
* app/gdisplay_ops.c: Set "allow_grow" to FALSE for "Really Quit?" and
"Changes were made to ... Close Anyway?".
* app/gimpui.c: fixed a compiler warning.
* app/tips_dialog.c: Same as above and did some code cleanup.
* app/colormap_dialog.i.c
* app/colormap_dialog.p.h: Allow dragging a color with mouse2
without changing the active color. Replaced the "index" entry with
a spinbutton. Code & UI cleanup.
1999-12-17 Michael Natterer <mitch@gimp.org>
* app/menus.c
* app/paths_dialog.c: Minor help system fixes.
* app/app_procs.c: I thought we should have a real splash (without
decoration). Like it???
* app/about_dialog.c
* app/flip_tool.c
* app/gradient.c
* app/levels.c
* app/measure.c
* app/text_tool.c
* app/tools.c
* app/transform_tool.c: Did some code browsing: I18N fixes,
s/gtk_window_position/gtk_window_set_position/g, indentation
paranoia, some g/<type>/g<type>/, various stuff (didn't change any
logic).
1999-12-02 Michael Natterer <mitch@gimp.org>
* app/app_procs.c: Default to "Cancel" in the "Really Quit?" dialog.
* app/app_procs.c
* app/brush_select.c
* app/gimpbrushlist.c: Call brush_select_[freeze|thaw]_all() from
brushes_init() and brushes_free(), so refreshing the brushes from
plugins/scripts is faster.
* app/brightness_contrast.c
* app/color_balance.c
* app/curves.c
* app/file_new_dialog.c
* app/hue_saturation.c
* app/levels.c
* app/posterize.c
* app/threshold.c:
Reorder the action are buttons: [ "OK" "Reset" "Cancel" ]
* app/menus.c: Some more cleanups in the menu code. Reorder
<Image>/Filters/Misc only if ot exists. Generalized
menu_translate() in preparation for correctly supporting catalogs
which only exist sometimes (like gimp-perl).
* app/gradient.c
* app/gradient_select.c: Save some lines of code by using
gtk_clist_new_with_titles() instead of gtk_clist_new().
* libgimp/gimpunitmenu.c: Code cleanup and made the clist titles
of the unit selection un-clickable.
1999-11-23 Michael Natterer <mitch@gimp.org>
* app/app_procs.c
* app/channels_dialog.c
* app/fileops.c
* app/gdisplay.c
* app/gdisplay_ops.c
* app/layers_dialog.c
* app/menus.[ch]
* app/paths_dialog.c
* app/plug_in.c: removed
menus_set_[sensitive|state]_glue(). Removed the N_()'s from all
menu paths which are not eventually passed to
gtk_item_factory_create_item().
* app/tool_options.c: minor updates.
* app/file_new_dialog.c: reordered the action_area buttons.
1999-11-20 Michael Natterer <mitch@gimp.org>
Reorganized the core menu items (everything except
<Image>/Filters). Everything is of course trivial to change again,
so please comment on the new "menu feeling" ;-)
* app/menus.[ch]:
- Applied the suggestions collected by Olof.
- Added "..." to all items which open a dialog.
- Introduced some additional separators (e.g. in "Dialogs").
- Reorder some plugins and the color correct tools after
initialisation.
- A menu entry to invoke the tooltips inspector.
- A debugging menu entry which dumps the menu paths and their help
pages (will of course go away when the help sys is consistent).
There are currently two identical "Help" menus because
<Toolbox>/Help trashes the menu bar if the toolbox is too narrow
(gtk doesn't seem to support multi-line menubars, any idea?)
* app/app_procs.c: call menus_reorder_plugins() after loading the
plugins to beautify the "Xtns" menu.
* app/commands.[ch]: reordered some functions to match the new
menu structure (for easier source navigation) and renamed some to
be consistent (e.g. all help functions are now called help_*).
Show/Hide the rulers with ordinary gtk_widget_[show|hide]()
commands. I've tested it several times and it looks exactly the
same as the old code which used internal gtk knowledge.
* app/gdisplay.c: applied the menu changes to
gdisplay_set_menu_sensitivity().
* app/gimphelp.[ch]: new public function gimp_context_help() which
invokes the tooltips inspector. Code cleanup.
* app/resize.c: changed the dialogs' titles to match the menu entries.
* app/session.c: renamed the gradient selection cmd callback to be
consistent with brushes/patterns.
* app/tools.c: added "..." to the menu paths of the tools which
have dialogs.
* app/fileops.c
* app/channels_dialog.c
* app/layers_dialog.c
* app/paths_dialog.c: added some "...".
* plug-ins/common/align_layers.c
* plug-ins/common/autostretch_hsv.c

* plug-ins/print/print.c
* plug-ins/rcm/rcm.c: changed the menu paths and added "...".
1999-10-30 Michael Natterer <mitch@gimp.org>
* app_procs.c
* app/commands.[ch]
* app/interface.c
* app/menus.c
* app/session.c
* app/tools.[ch]: namespace cleanups: changed the
"tools_options_*" functions to "tool_options_*" and prefixed all
dialog menu callbacks with "dialogs_*".
Allow dropping a tool to the tool options dialog.
* app/bezier_select.c: change the active tool using context
functions.
* app/dialog_handler.[ch]: replaced the uppercase datatype names
by standard mixed upper/lowercase ones. Provide a function to
register the fileload dialog instead of accessing it as global
variable.
* app/disp_callbacks.c: switch to the move tool using context
functions. Fixed the drop color/pattern functions to convert the
dropped thing to the dest. image's color space.
* app/fileops.c: don't export the fileload dialog as global
variable but register it with the dialog handler instead.
* app/paths_dialog.[ch]: replaced all the uppercase struct names
defined here by mixed upper/lowercase. Introduced a
"set_menu_sensitivity" function like in layers/channels instead of
calling single button on/off functions from various places.
Added a menu entry for "Selection to Path".
* app/app_procs.c
* app/gdisplay_color.[ch]
* app/gdisplay_color_ui.c: make the ui usable
* app/gdisplay.c: enable cdisplay support
* modules/Makefile.am
* modules/cdisplay_gamma.c: moved gamma functionality to separate
-Yosh
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 ;-)
* app/app_procs.c
* app/brush_edit.c
* app/brush_select.c
* app/channel_ops.c
* app/channels_dialog.c

* app/pattern_select.c
* app/preferences_dialog.c
* app/qmask.c
* app/resize.c
* app/undo_history.c: changed all dialog constructors to point
to the right place in the new help file structure.
* configure.in
* help/*: the basic new help file structure.
* modules/colorsel_gtk.c
* modules/colorsel_triangle.c
* modules/colorsel_water.c: register a help page.
* plug-ins/helpbrowser/helpbrowser.c: load the help files
according to the new help file structure.
1999-09-27 Michael Natterer <mitch@gimp.org>
* app/Makefile.am
* app/gimphelp.[ch]
* app/gimpui.[ch]: new files
* app/interface.[ch]
* app/preferences_dialog.[ch]
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).
