2001-08-30 Michael Natterer <mitch@gimp.org>
* app/plug_in.c
* libgimpbase/gimpwire.c
* libgimp/gimp.c: removed GIOChannel "channel->funcs->io_foo()"
hacks and use plain g_io_channel_[read|write]_chars(). An
additional g_io_channel_set_buffered (channel, FALSE); is needed
to make the channels work in binary mode. Fixed misc other stuff
in the GIOChannel code.
* app/tools/gimpdrawtool.c
* app/tools/gimpmovetool.c
* app/tools/gimptransformtool.c
* app/widgets/gimpdialogfactory.c
* libgimpwidgets/gimpcolorarea.c
* libgimp/gimpui.c: replaced some deprecated GDK functions.
* app/gui/palette-editor.c: block the color_name entry's "changed"
signal while setting it. Fixes invalid UTF-8 warnings.
2001-08-30 Sven Neumann <sven@gimp.org>
* configure.in: check for bind_textdomain_codeset, use standard
HAVE_FOO semantic for difftime.
* libgimp/gimpintl.h
* libgimp/libgimp-intl.h
* libgimp/stdplugins-intl.h: set encoding of message translations
to UTF-8 if bind_textdomain_codeset() is available. We still
explicitely set LC_NUMERIC to "C" so we can write and parse floats
in a defined way independent of the locale. We might want to find
a cleaner solution for this.
* plug-ins/script-fu/script-fu-server.c: inverted preprocessor logic
from NO_DIFFTIME to HAVE_DIFFTIME.
* plug-ins/script-fu/scripts/trochoid.scm:
fixed parameter description (bug #59760).
2001-08-29 Sven Neumann <sven@gimp.org>
* README.i18n: added a section that mentions the GNOME translation
project that coordinates translation efforts in the GNOME CVS tree.
Mention the fact that po files as well as the tips files need to be
UTF-8 encoded to work with GTK+-2.0.
* tips/gimp_tips.de.txt: converted to UTF-8.
2001-08-29 Sven Neumann <sven@gimp.org>
* README.i18n: added a section that mentions the GNOME translation
project that coordinates translation efforts in the GNOME CVS tree.
2001-08-29 Sven Neumann <sven@gimp.org>
* app/widgets/gtkhwrapbox.[ch]
* app/widgets/gtkvwrapbox.[ch]
* app/widgets/gtkwrapbox.[ch]: make it compile even if you don't
have gle installed ;-)
2001-08-29 Sven Neumann <sven@gimp.org>
* configure.in: added comment how to handle version numbers when
making releases so I don't get it wrong once again.
Removed leftover GIMP_CONTRIBUTORS.
* gimptool.1.in: removed this file.
* docs/Makefile.am
* docs/gimp.1.in: fixed stuff that was left after the removal of
the GIMP_CONTRIBUTORS hack.
2001-08-28 Sven Neumann <sven@gimp.org>
* configure.in: removed the authorgen hack. It broke the build with
autoconf-2.52. Need to come up with a better idea. Until then the
manpages don't show the autors anymore.
Removed the useless definitions of brushdata, palettedata, ...
while I was on it.
* data/Makefile.am
* data/brushes/Makefile.am
* data/gradients/Makefile.am
* data/palettes/Makefile.am
* data/patterns/Makefile.am: do it the conventional way and list all
data files in the Makefiles.
2001-08-28 Sven Neumann <sven@gimp.org>
* acinclude.m4: removed redefinitions of libtool macros. We use the
installed libtool now. If this breaks the build for your system,
upgrade libtool. If that does not help, let us know.
* ltconfig
* ltmain.sh: removed these files. Newer versions of libtool don't use
ltconfig and ltmain.sh is taken from your libtool installation.
* autogen.sh: check for presence of libtool.
* Makefile.am
* configure.in
* gimp-remote.1.in
* gimp.1.in
* gimprc.5.in: removed man-pages from toplevel dir ...
* docs/Makefile.am
* docs/gimp-remote.1.in
* docs/gimp.1.in
* docs/gimprc.5.in
* docs/gimptool-1.4.1.in: ... and added them back here.
* gimp-1.4.m4: removed from toplevel dir ...
* m4macros/Makefile.am
* m4macros/gimp-1.4.m4: ... and added it back here.
2001-08-19 Sven Neumann <sven@gimp.org>
* app/devices.h
* app/disp_callbacks.c
* app/interface.c: applied a patch from <David.Odin@bigfoot.com> that
changes some function prototype to return gboolean instead of gint.
* app/tools/gimpblendtool.c: pixel_regions_register() and
pixel_regions_process() return a gpointer, not (gpointer *).
2001-08-17 Michael Natterer <mitch@gimp.org>
* configure.in: added app/display/ and app/plug-in/. Empty for
now except for the types files.
* app/Makefile.am
* app/appenums.h

* app/appenv.h: added MessageHandlerType and StackTraceMode here.
* app/undo_types.h: moved undo struct typedefs here.
* app/tools/tools-types.h
* app/core/core-types.h: added some enums and Tattoo here
(renamed to GimpTattoo).
* app/gdisplay.h: temp_hack: #include "display/display-types.h"
* app/gimphelp.c: s/gtk_idle_add/g_idle_add/
* app/gimprc.c: don't use "gimprc" in token handlers but the
passed "val1p" and "val2p".
* app/image_map.[ch]: cleanup in preparation of making a GObject
out of it.
* app/base/pixel-region.[ch]: no need to pass the
PixelRegionIterator around as void pointer.
* app/core/gimp.[ch]
* app/core/gimpcontext.[ch]
* app/core/gimptoolinfo.[ch]
* app/tools/tool_manager.c

* app/widgets/gimpdockbook.c
* app/widgets/gimppreview.c
* app/xcf/xcf-load.c
* app/xcf/xcf-save.c
* app/xcf/xcf.c: changed accordingly: s/Tattoo/GimpTattoo/, include
the new types files, include <glib-object.h> instead of >gtk/gtk.h>.
Bad hacks to get rid of SELECTION_OFF and friends in core/ (will
be replaced ba a signal soon).
* tools/pdbgen/Makefile.am: changed list of headers scanned for
enums accordingly.
* app/pdb/procedural_db.c
* tools/pdbgen/app.pl
* tools/pdbgen/pdb/channel.pdb
* tools/pdbgen/pdb/display.pdb
* tools/pdbgen/pdb/gradient_select.pdb
* tools/pdbgen/pdb/image.pdb
* tools/pdbgen/pdb/layer.pdb
* tools/pdbgen/pdb/pattern_select.pdb: same fixes as above, added
hacks to ensure that all foo-types.h files are included before all
other gimp internal includes, include "pdb-types.h" unconditionally.
* tools/pdbgen/enums.pl
* app/pdb/*_cmds.c: regenerated.
2001-08-15 Michael Natterer <mitch@gimp.org>
* app/tools/gimptool.[ch]
* app/tools/tool_manager.[ch]: removed all *_get_PDB_string()
functions and GimpToolClass' "pdb_string" field as this info is
stored independent from a specific tool instance in GimpToolInfo
* app/tools/gimpbezierselecttool.c: use GimpToolInfo's "pdb_string".
2001-08-14 Michael Natterer <mitch@gimp.org>
* app/gdisplay.h: an evil temp_hack which lets GimpContext managing
the active display withoug including "gdisplay.h". Will go away as
soon ad context properties are registered dynamically.
* app/module_db.c: cleaned up the object code in preparation of
moving it to core/.
* app/path.c: connect to GimpImage's
* app/core/gimpobject.[ch]: derive it from GObject, not from
GtkObject any more (yeah :-)
* app/core/*.c: #include <glib-object.h> instead of <gtk/gtk.h>,
removed some remaining GtkObject-isms.
(left in a few #include <gtk/gtk.h> where bigger changes are needed
to get rid of the UI dependency).
* app/core/core-types.h: #include <gdk-pixbuf/gdk-pixbuf.h> here
temporarily.
* app/core/gimp.c (gimp_create_display): unref the image after
creating it's first display.
* app/core/gimpbrush.[ch]: disabled the parts of the code which
depend on GimpPaintTool.
* app/core/gimpbrushgenerated.c
* app/core/gimpbrushpipe.c: changed accordingly.
* app/core/gimpcontext.[ch]: evil hack (see above) to manage the
active display without including "gdisplay.h"
* app/core/gimpimage-mask.[ch]: pass a context to
gimage_mask_stroke() and get the current tool's PDB string from
there.
* app/core/gimpedit.c: changed accordingly.
* app/core/gimpimage.c: use gimp_image_update() instead of
gdisplays_update_full().
* app/gui/color-area.c
* app/gui/colormap-dialog.c
* app/gui/dialogs-constructors.c
* app/gui/edit-commands.c
* app/gui/image-commands.c
* app/gui/toolbox.c: changed accordingly (don't use Gtk methods on
GObjects).
* app/gui/menus.c: fix some const warnings by explicit casting.
* app/tools/*.[ch]: ported all tools to GObject, some minor
cleanup while i was on it.
* app/widgets/gimpdialogfactory.[ch]: ported to GObject.
* app/widgets/gimplayerlistview.h: added FOO_GET_CLASS() macro.
* tools/pdbgen/app.pl: added a "widgets_eek" hack like "tools_eek"
which inserts #include "widgets/widgets-types.h" before ordinary
includes.
* tools/pdbgen/pdb/brush_select.pdb
* tools/pdbgen/pdb/edit.pdb
* app/pdb/brush_select_cmds.c
* app/pdb/edit_cmds.c: changed according to the stuff above.
2001-08-14 Sven Neumann <sven@gimp.org>
* app/tools/gimptexttool.c: take image resolution and choosen unit
into account for font and border size.
* app/widgets/gimpfontselection-dialog.[ch]
* app/widgets/gimpfontselection.[ch]
* app/widgets/widgets-types.h: added an indicator for font validity.
Added a font preview to the font selection dialog.
* libgimpwidgets/gimpfileselection.c: return FALSE from
gimp_file_selection_entry_focus_out_callback() since we do not want
to stop signal emission.
2001-08-12 Michael Natterer <mitch@gimp.org>
Switched to GObject reference counting:
* app/core/gimpcontainer.c: only ref(), not ref()/sink() children
of strong containers. Reordered gimp_container_remove() so we
don't need to ref the object while removing it.
* app/core/gimpcontext.c: misc fixes. Needs to be badly tortured...
* app/app_procs.c
* app/gdisplay.c
* app/gimprc.c
* app/core/gimp.c
* app/core/gimpbrush.c
* app/core/gimpbrushpipe.c
* app/core/gimpdatafactory.c
* app/core/gimpdocuments.c
* app/core/gimpgradient.c
* app/core/gimpimage.c
* app/core/gimplayer.c
* app/core/gimplist.c
* app/core/gimpobject.c
* app/core/gimpparasite.c
* app/core/gimppattern.c
* app/core/gimpundostack.c
* app/gui/dialogs.c
* app/tools/gimpbezierselecttool.c
* app/tools/gimpfuzzyselecttool.c: changed accordingly: don't
ref()/sink() any more, unref all (??) objects after adding them to
strong containers, misc. minor fixes.
* app/gui/dialogs-constructors.c
* app/widgets/gimpwidgets.c: use g_object_add_weak_pointer()
instead of simply crashing because g_object_weak_ref() was used
with gtk_widget_destroyed, brrr.
* app/widgets/gimpdnd.c: removed unneeded g_return_if_fail()'s.
2001-08-11 Sven Neumann <sven@gimp.org>
* app/tools/gimptexttool.c: return the created layer.
* app/pdb/text_tool_cmds.c
* libgimp/gimptexttool_pdb.c
* tools/pdbgen/pdb/text_tool.pdb: hacked a bit so scripts using the
text_*_fontname procedures work again with the new text tool.
The fontname is however no longer a X Logical Font Description, but
the much simpler scheme that Pango understands:
"[FAMILY-LIST] [STYLE-OPTIONS]". Interactive font selection is still
broken. The variants of the text PDB calls that pass the XLFD fields
directly should also work since the PDB now translates this to a
Pango-conform fontname. Later this API will die, but for the moment,
some backward compatibility can't hurt...
2001-08-11 Michael Natterer <mitch@gimp.org>
* app/core/gimp.c: split "destroy" up in "dispose" and "finalize".
* app/core/gimpcontext.c: objects need to be passed around with
g_param_spec_object() or bad things will happen.
* app/gui/channels-commands.c
* app/gui/edit-commands.c
* app/gui/file-commands.c
* app/gui/gui.c
* app/gui/layers-commands.c
* app/gui/resize-dialog.c
* app/gui/select-commands.c
* app/tools/gimpclonetool.c
* app/widgets/gimpdatafactoryview.c
* app/widgets/gimppreview.c: removed many connections to
"destroy": Connect to "dispose" or use g_object_weak_ref()
instead.
2001-08-11 Michael Natterer <mitch@gimp.org>
* configure.in: fsck^^^ -- lovely autofoo wants "changequote([,])dnl"
* app/core/gimpcontext.[ch]: lots of GObject porting.
* app/core/gimpobject.[ch]: added a "disconnect" signal, which
like gtk's "destroy" is emitted in dispose(). This is ugly but
I don't see another "clean" way to implement weak containers.
* app/core/gimpcontainer.c: connect to the "disconnect" signal of
the children of weak containes.
* app/core/gimpimage.[ch]: replaced the "destroy" implementation
with "dispose" + "finalize". Removed gimage->undo_history.
* app/devices.c
* app/gui/dialogs-constructors.c
* app/gui/tools-commands.c
* app/tools/tool_manager.c
* app/widgets/gimpimagedock.c: changed accordingly.
2001-08-11 Sven Neumann <sven@gimp.org>
* app/tools/gimptexttool.c: allow to specify size and border.
* app/widgets/gimpfontselection.c: use GTK_STOCK_SELECT_FONT icon.
2001-08-11 Sven Neumann <sven@gimp.org>
* configure.in: added dependency on PangoFT2 (Pango compiled with
FreeType2 support).
* app/Makefile.am: link against PangoFT2.
* app/tools/Makefile.am
* app/tools/gimptexttool.[ch]: rudimentary new text tool. Still needs
lots of work.
* app/widgets/Makefile.am
* app/widgets/widgets-types.h:
* app/widgets/gimpfontselection-dialog.[ch]
* app/widgets/gimpfontselection.[ch]: added font selection widgets.
* libgimpwidgets/Makefile.am
* libgimpwidgets/gimpwidgetstypes.h
* libgimpwidgets/gimpfontselection.[ch]: removed font selection code
from here since the fonts need to be selected from the core's
PangoContext. Will add PDB-controlled font selection later.
2001-08-11 Michael Natterer <mitch@gimp.org>
* TODO.xml: added a TODO entry about additional image/file info.
* app/file-save.c: #include "core/gimpdocuments.h"
* app/core/gimpcontainer.[ch]: made virtual functions out of some
signals.
* app/core/*.[ch]: more GObject stuff: ported all
gimp_foo_get_type() functions and replaced almost all "destroy"
implementations with either "finalize" or "dispose" functions.
2001-08-11 Michael Natterer <mitch@gimp.org>
* app/core/Makefile.am
* app/core/gimpdocuments.[ch]: new file implementing the
docindex.* replacement.
* app/gimprc.c: added TT_XDOCUMENT to parse the new document
history.
* app/file-save.c
* app/gui/file-open-dialog.c: add opened & saved images to the
document history.
* app/core/gimp.c: call gimp_documents_init/exit() instead of
doing it here.
* app/core/gimpimagefile.[ch]: removed the "filename" attribute
and use GimpObject's "name" instead.
* app/gui/dialogs-constructors.[ch]
* app/gui/dialogs.c
* app/gui/menus.c: added a menu entry/dockable for the document
history.
* app/widgets/gimpdnd.[ch]: make it DND-able.
* app/widgets/gimppreview.c: fix preview rendering correctly this
itme.
2001-08-10 Sven Neumann <sven@gimp.org>
* libgimpwidgets/Makefile.am
* libgimpwidgets/gimpwidgetstypes.h
* libgimpwidgets/gimpfontselection.[ch]: added a rudimentary font
selection widget, mostly copied from GtkFontSelection.
* libgimpwidgets/gimpfileselection.c: more GObject porting.
2001-08-10 Michael Natterer <mitch@convergence.de>
* app/nav_window.c: fix compiler warning.
* app/core/gimp.[ch]: added gimp->documents which will be an MRU
list of GimpImagefile objects.
* app/core/gimpcontainer.c: added some g_return_if_fail().
* app/gui/palette-editor.c: use GtkImage instead of GtkPixmap,
s/gtk_signal_*/g_signal_*/.
* app/widgets/gimppreview.c: render the checkerboard only for
channel == -1. In particular, don't render it for channel
previews.
* app/module_db.c
* app/core/*.c
* app/gui/colormap-dialog.c
* app/tools/gimpairbrushtool.c
* app/tools/gimpdodgeburntool.c
* app/tools/gimpeditselectiontool.c
* app/tools/gimperasertool.c
* app/tools/gimppaintbrushtool.c
* app/tools/gimppenciltool.c
* app/tools/gimpsmudgetool.c
* app/tools/tool_manager.c
* app/widgets/*.c
* libgimpwidgets/*.c: s/gtk_type_new/g_object_new/
2001-08-09 Michael Natterer <mitch@gimp.org>
* app/appenums.h: removed GIMP_ZOOM_TYPE,
* app/widgets/widgets-types.h: added it here.
* app/disp_callbacks.c
* app/widgets/gimpnavigationpreview.[ch]
* app/gui/gradient-editor.c: removed old cruft which expects wheel
events as button_4 and button_5 and connect to GdkEventScroll
instead.
* app/nav_window.c: connect to GimpNavigationPreview's new
"scroll" and "zoom" signals.
* app/gui/error-console-dialog.c: remove wheel scrol stuff (done
by GtkScrolledWindow now).
* app/gui/color-notebook.c
* app/gui/gradient-editor.c: removed GtkPixmap stuff and use
GtkImage instead. Looks a bit ugly in the color_notebook (seems
we need more icon sizes).
* app/gui/indicator-area.c: GObject porting.
* app/gui/menus.c_ some more menu icons.
* app/gui/toolbox.c: pass a GimpContext around as callback data
and use context->gimp instead of accessing the global "the_gimp"
variable.
2001-08-09 Sven Neumann <sven@gimp.org>
* app/core/Makefile.am
* app/core/core-types.h
* app/core/gimpimagefile.[ch]: added first draft of a GimpImagefile
object that will handle image files on disk, in particular their
thumbnails.
2001-08-07 Michael Natterer <mitch@gimp.org>
* app/disp_callbacks.c: removed a gdk_pointer_ungrab(), it was
only there because of buggy gtk+ 1.2.x. Cosmetic changes.
* app/undo.c: use G_N_ELEMENTS() instead of
sizeof(array)/sizeof(element).
* app/gui/menus.c: more stock icons, moved the item_factory
creation into the menus_get_foo_factory() functions, use
G_N_ELEMENTS(). This file badly needs to be spit up...
* app/core/gimpviewable.[ch]
* app/widgets/gimpcontainermenu.[ch]
* app/widgets/gimpcontainerview.[ch]
* app/widgets/gimplistitem.[ch]
* app/widgets/gimpmenuitem.[ch]
* app/widgets/gimppreview.[ch]: replaced tons of signal emissions
by virtual functions which are *much* faster. Moreover, all of
them are private implementation bits of the specific class
hierarchy and are useless or even dangerous to be exposed as
signals.
* app/widgets/gimpdrawablelistitem.c: removed the drag_motion()
implementation as it's already done in the parent class.
* app/widgets/gimplistitem.[ch]
* app/widgets/gimplayerlistitem.c: redraw the widget when the
drop_type has changed. Fixes drop_indicator drawing.
2001-08-07 Michael Natterer <mitch@gimp.org>
* libgimpwidgets/gimpbutton.[ch]: cleanup.
* app/Makefile.am
* app/errorconsole.[ch]: removed...
* app/gui/Makefile.am
* app/gui/error-console-dialog.[ch]: ...added here. Lots of cleanup,
create a vbox instead of a dialog.
* app/gui/dialogs-constructors.c
* app/gui/dialogs.c: added a dockable for the error console.
* app/errors.c
* app/gui/gui.c
* app/gui/menus.c: changed accordingly.
* app/widgets/gimpcontainerview.c: conntect "extended_clicked" to
the "extended_clicked" callback, not "clicked".
* app/widgets/gimplayerlistview.c: set the layer option box'
spacing in "style_set".
* app/widgets/gimplistitem.c: argh.
* themes/Default/gtkrc: changed the default theme to set a smaller
font only for the dockable because that's where saving screen
estate really makes sense. May need some further tweaking.
2001-08-06 Michael Natterer <mitch@gimp.org>
* configure.in
* themes/Default/images/Makefile.am
* themes/Default/images/tools/Makefile.am: some new Makefiles to
make it installable.
* Makefile.am
* gtkrc: removed...
* themes/Default/Makefile.am
* themes/Default/gtkrc: ...added here.
* themes/Default/imagerc: new file (not used, just for
documentation) which loads the default theme's images in the same
way the inlined pixbufs are registered with the stock system.
* gimprc.in
* gimprc.win32
* user_install
* user_install.bat
* app/gimprc.[ch]: added "theme-path" and "theme" gimprc variables.
* app/app_procs.c: prase gimprc before initializing the GUI.
* app/core/gimpdatafiles.[ch]: added support for getting only
subdirectories in the callback.
* libgimpbase/gimpenv.c: as a temp_hack gimp_gtkrc(); returns the
default theme's gtkrc.
* app/gui/gui.c: build a hash of theme directories and select
the one configured in gimprc.theme. Use gimp_gtkrc()'s default
value if there is no theme installed or configured.
* app/gui/preferences-dialog.c: Added theme_path to the GUI. No
stuff for selection the theme yet.
* app/gui/menus.c: beautify <Image>/Tools/
* app/tools/gimpcroptool.c: register in <Image>/Tools/Transform Tools/
2001-08-05 Michael Natterer <mitch@gimp.org>
* Makefile.am
* configure.in
* themes/.cvsignore
* themes/Makefile.am
* themes/Default/.cvsignore
* themes/Default/Makefile.am
* themes/Default/images/.cvsignore
* themes/Default/images/*.png
* themes/Default/images/tools/.cvsignore
* themes/Default/images/tools/*.png: new place for all images
which are registered with the stock system. The default images are
all inlined but we will install the default theme later along with
an appropriate gtkrc as a template for custom themes.
Added PNGs of all tools icons. Thanks to syngin :)
* pixmaps/.cvsignore
* pixmaps/Makefile.am: reverted everything to the old state. This
directory will go away soon.
* libgimpwidgets/gimpstock.[ch]: changed accordingly. Register
stock icons in GTK_ICON_SIZE_BUTTON for all tools.
* app/core/gimptoolinfo.[ch]
* app/tools/tool_manager.[ch]: GimpToolInfo wants a stock_id and a
pre-rendered GdkPixbuf instead of ugly icon_data now. Added some
workarounds until GimpPreview is a GtkImage and uses GdkPixbuf
instead of TempBuf.
* app/tools/Makefile.am
* app/tools/icons.h: die, uglyness, die.
* app/tools/[all tools].c: register with a stock_id, not a
icon_data pointer.
* app/gui/dialogs-constructors.c: Oops, GIMP badly crashed on
changing the image for the past few days :)
* app/gui/menus.c: create the tools' menu entries with stock
icons.
* app/gui/toolbox.c: use GtkImages instead of GimpPreviews for
the toolbox buttons. Will need to change this back as soon
as GimpPreview actually _is_ a GtkImage.
