Better factorize by reusing code rather than recreating a combo box
which does basically the same thing. I only added a boolean parameter to
retrieve only the sublist of manual language.
It also takes advantage of the self-translated language names from
initialization.
Try harder to show help when webkit is missing or the help browser
won't start:
- offer to switch to the web browser when the help browser is
present, but won't start for some reason
- in prefs, don't bother showing the help browser GUI when webkit
is missing, otherwise show a warning label if the help browser
is not installed even though webkit is there. Switch to the web
browser in both cases (modified patch from lisanet)
- add OS X replacement for gtk_show_uri() in plug-in-web-browser
(modified patch from lisanet)
2009-02-26 Sven Neumann <sven@gimp.org>
* app/gui/gui.c (gui_restore_callback): connect to changes of
the
"user-manual-online" gimprc property and kill the gimp-help
plug-in as it caches the location of the help pages.
* app/widgets/gimphelp.[ch]: added
gimp_help_user_manual_changed()
for this purpose.
svn path=/trunk/; revision=28073
2009-01-17 Michael Natterer <mitch@gimp.org>
* all files with a GPL header and all COPYING files:
Change licence to GPLv3 (and to LGPLv3 for libgimp).
Cleaned up some copyright headers and regenerated the parsers in
the ImageMap plugin.
svn path=/trunk/; revision=27913
2008-07-05 Sven Neumann <sven@gimp.org>
* app/dialogs/preferences-dialog.c
* app/widgets/gimphelp.[ch]: improved test for user manual
installation and moved the code out of the prefs dialog.
svn path=/trunk/; revision=26067
2008-07-04 Sven Neumann <sven@gimp.org>
* app/widgets/gimphelp.[ch]: added a function to get the
location
where the user manual is expected if it is installed locally.
* app/dialogs/preferences-dialog.c: inform the user about the
presence or absence of the user manual.
svn path=/trunk/; revision=26058
2004-07-10 Michael Natterer <mitch@gimp.org>
Removed any remaining GUI dependency from the PDB wrappers:
* app/core/gimp.[ch]: added vtable entries for the display and
help stuff.
* app/widgets/gimphelp.[ch]: renamed gimp_help() to
gimp_help_show().
* app/gui/gui-vtable.c: implement the new display and help vtable
entries.
* tools/pdbgen/pdb.pl
* tools/pdbgen/pdb/display.pdb
* tools/pdbgen/pdb/help.pdb: use the new functions of the Gimp
object instead of using stuff from display/ and widgets/.
* tools/pdbgen/app.pl: removed bad hacks which enabled including
stuff from gui/, display/ and widgets/.
* app/Makefile.am: link widgets-enums.o, display-enums.o and
gimpdisplayoptions.o into the gimp-console binary because they are
needed for the config system and don't depend on any GUI stuff.
* app/pdb/Makefile.am: s/GTK_CFLAGS/GDK_PIXBUF_CFLAGS/
* app/pdb/display_cmds.c
* app/pdb/help_cmds.c: regenerated.
2003-08-28 Michael Natterer <mitch@gimp.org>
Completed the new help infrastructure. Needs some polishing but
basically works as proposed:
* tools/pdbgen/pdb/plug_in.pdb: changed gimp_plugin_help_register()
to take a "domain_name" (which is the XML namespace) and a
"domain_uri" (which is the root of the plug-in's help pages).
* tools/pdbgen/pdb/help.pdb: changed gimp_help() to take help_id
instead of a non-UTF-8 help_path.
* app/plug-in/plug-in-def.[ch]
* app/plug-in/plug-in-proc.[ch]
* app/plug-in/plug-in-rc.c
* app/plug-in/plug-ins.[ch]: remember the plug-ins' help_domain
and help_uri instead of just help_path. Changed all plug-in APIs
to reflect this change.
* app/widgets/gimphelp.[ch]: on helpbrowser startup, pass it the
whole list of help domains. The actual help request is now made
using the browser's temporary procedure.
* app/core/gimp.h
* app/gui/file-open-menu.c
* app/gui/file-save-menu.c
* app/gui/plug-in-menus.[ch]
* app/widgets/gimpitemfactory.c: changed accordingly.
* app/pdb/help_cmds.c
* app/pdb/plug_in_cmds.c
* libgimp/gimphelp_pdb.[ch]
* libgimp/gimpplugin_pdb.[ch]: regenerated.
Changed the help broser to load the pages according to the
new system:
- moved the browser window stuff to dialog.[ch]
- moved help domain handling to domain.[ch]
- added gimp-help.xml parsing to domain.c
- tons of cleanup
* plug-ins/helpbrowser/Makefile.am
* plug-ins/helpbrowser/dialog.[ch]
* plug-ins/helpbrowser/domain.[ch]: new files.
* plug-ins/helpbrowser/helpbrowser.c: chopped.
2003-08-23 Michael Natterer <mitch@gimp.org>
* libgimpwidgets/gimpwidgetstypes.h: changed GimpHelpFunc typedef:
- renamed "const gchar *help_data" to "const gchar *help_id".
- added "gpointer help_data".
* libgimpwidgets/gimphelpui.[ch]: added "gpointer help_data" to
gimp_help_connect(). Removed all fiddling with html links and
treat all help IDs as opaque identifiers.
* app/core/gimptoolinfo.[ch]: changed "help_data" member to
"help_id".
* app/widgets/gimpitemfactory.[ch]: removed the "help_path"
parameter from gimp_item_factory_new() since we don't fiddle with
html file paths any more. Simplifies menu item help a lot.
Renamed "help_data" member of struct GimpItemFactoryEntry to
"help_id".
* app/gui/plug-in-menus.c: changed accordingly. 3rd party
plug-ins' menu item help IDs are now encoded as
"help_path:help_id".
* app/gui/file-open-menu.c
* app/gui/file-save-menu.c: when constructing the <Load> and
<Save> menus, take the resp. procedures' locale_domain and
help_path into account. Fixes translation of 3rd party menu items.
Also do the right thing for load/save procs which are implemented
as temporary procedures (they are impossible to implement
currently but it's nice to do the right thing anyway...).
* app/widgets/gimphelp-ids.h: added GIMP_HELP_MAIN identifier.

2002-05-05 Michael Natterer <mitch@gimp.org>
* app/Makefile.am
* app/gimphelp.[ch]: removed...
* app/widgets/Makefile.am
* app/widgets/gimphelp.[ch]: ...and added here.
* app/widgets/widgets-enums.[ch]: added GimpHelpBrowserType here
as registered enum. Added an evil hack with GimpCursorType so
app/config/gimpguiconfig.h can include this file.
* app/widgets/gimpcursor.c: added an assertion because of the
changed GimpCursorType.
* app/config/gimpguiconfig.[ch]: added a property for the help
browser type.
* app/gimprc.c
* app/libgimp_glue.c
* app/gui/preferences-dialog.c
* tools/pdbgen/pdb/help.pdb
* app/pdb/help_cmds.c: regenerated.
Some nav_window cleanup before chopping:
* app/nav_window.[ch]: removed the old preview code and use
GimpNavigationPreviews only. Namespaceified all functions. Speak
in terms of GimpDisplayShell, not GimpDisplay. Lots of internal
cleanup.
* app/gui/gui-types.h: removed NadiagtionDialog here...
* app/display/display-types.h: ...and added it here.
* app/display/gimpdisplayshell-callbacks.[ch]: added a callback
for the navigation button and call nav_window_show_popup() from there.
* app/display/gimpdisplayshell.c: free shell->nav_dialog
unconditionally, connect to the new callback.
* app/display/gimpdisplayshell-scale.c
* app/display/gimpdisplayshell-scroll.c
* app/gui/view-commands.c: changed accordingly.
* app/widgets/gimppreview.c (gimp_preview_set_viewable): the
assertion introduced recently was too tight, breaking
GimpNavigationPreview. Changed it to do an "is a" check, not exact
preview type matching.
* app/widgets/gimpimagepreview.c: added quick-hack support for
xres != yres.
* app/widgets/gimpnavigationpreview.[ch]: made
gimp_navigation_preview_grab_pointer() public so the nav_window
can call it.
Unrelated:
* app/display/gimpdisplay.c: removed the gui/ dependency from this
file by removing info_window stuff.
* app/display/gimpdisplayshell.c (gimp_display_shell_flush): update
the info_window here.
* app/gui/dialogs-constructors.c (dialogs_indexed_palette_new): call
gimp_dockable_set_context() like all other constructors.
* app/undo.c
* app/paint/gimppaintcore.h: some more include cleanup.
2002-04-12 Michael Natterer <mitch@gimp.org>
Well, sometimes the most obvious solution is not the first one...
* app/gimphelp.[ch]: removed _gimp_standard_help_func().
* app/libgimp_glue.c (gimp_standard_help_func): call gimp_help()
directly.
2002-04-12 Michael Natterer <mitch@gimp.org>
* app/gimphelp.[ch]: removed usage of "the_gimp" by passing around
more "Gimp" pointers. Renamed gimp_standard_help_func() to
_gimp_standard_help_func() and declare it in the header. Don't
include "app_procs.h".
* app/libgimp_glue.[ch]: added gimp_standard_help_func() here.
Call _gimp_standard_help_func (the_gimp, ...) like all other
wrappers in this file do. I know this is ugly but better let's
have all uglyness in one place (here) :-)
* app/widgets/gimpitemfactory.[ch]: added a "Gimp" member to the
GimpItemFactory struct. Pass it to gimp_help(),
* app/gui/menus.c: pass a Gimp to gimp_item_factory_new(), removed
useless inclusion of "gimphelp.h".
* tools/pdbgen/pdb/help.pdb: pass a Gimp to gimp_help()
* app/pdb/help_cmds.c: regenerated.
* app/gui/tips-dialog.c: removed gtk_quit_add_destroy() here too
because the tips dialog is created by a dialog factory which takes
care of dialog destruction.
2000-12-29 Michael Natterer <mitch@gimp.org>
* app/Makefile.am
* app/channel_pvt.h
* app/drawable_pvt.h
* app/gdisplayF.h

* app/gimpimageP.h
* app/layer_pvt.h
* app/toolsF.h: removed these files.

* 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/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.
2000-11-18 Michael Natterer <mitch@gimp.org>
* app/fileops.c
* libgimp/gimpquerybox.[ch]: Make sure that we don't try to destroy
query_boxes twice or try to disconnect not-any-more connected
handlers.
* app/color_notebook.c
* app/gimpcontext.[ch]
* app/gimphelp.[ch]
* app/lc_dialog.[ch]

* libgimp/gimpsizeentry.[ch]

* libgimp/gimpunitmenu.[ch]
* libgimp/gimpwidgets.[ch]: in a coding attack, changed help_data
and many other strings passed to UI functions to (const gchar *).
As a consequence, I had to fix lots of warnings ;)
* plug-ins/common/tga.c
* plug-ins/imagemap/imap_main.c: fixed warnings.
Code cleanup and indentation all over the place.
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 :(
2000-01-11 Michael Natterer <mitch@gimp.org>
* app/gimphelp.h
* libgimp/gimp.h
* libgimp/gimphelpui.[ch]: declare the gimp_standard_help_func in
gimphelpui.h because libgimp widgets must not include libgimp/gimp.h.
* libgimp/gimpdialog.c
* libgimp/gimpexport.c
* libgimp/gimpunitmenu.c: use the dialog constructor for the
export dialog and the unit selection.
* plug-ins/gpc/gpc.[ch]
* plug-ins/megawidget/megawidget.[ch]: removed unused functions
(dialog creation and some other stuff). The rest of these libs is
scheduled for removal, too...

more plugins. Did some indentation, prototyping and I18N fixes.
2000-01-05 Michael Natterer <mitch@gimp.org>
* app/gimphelp.[ch]: removed most functions. Show the help page in
an idle function to avoid confusion with calling the temporary
help browser procedure in the middle of the "gimp_help" PDB call.
(I beleive this should work, so this is maybe a workaround for
some other bug).
* app/gimpui.[ch]: removed the dialog functions.
* libgimp/Makefile.am
* libgimp/gimpdialog.[ch]
* libgimp/gimphelp.c
* libgimp/gimphelpui.[ch]: new files. Moved most of the help
functions and the dialog constructors to libgimp and libgimpui.
* libgimp/gimp.h: declaration of the "gimp_help*" functions.
* libgimp/gimpui.h: include "gimpdialog.h" and "gimphelpui.h".
* plug-ins/common/grid.c: use the dialog constructor. It's now
possible to show the plugin's help with "F1".
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.
1999-11-20 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/common/c_astretch.c
* plug-ins/common/color_enhance.c
* plug-ins/common/compose.c

* 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/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.
1999-09-27 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).
