2001-07-24 Michael Natterer <mitch@gimp.org> Port to glib/gtk+ 2.0 episode I (every segfault has it's beginning) * configure.in: require glib/gtk+ >= 1.3.7, commented out the gtkxmhtml stuff. From now on, you will need glib, pango, atk and gtk+ HEAD from CVS to hack or use GIMP HEAD. Beware, it crashes randomly :) * app/core/Makefile.am * app/core/gimpmarshal.list: new file plus rules to generate gimpmarshal.[ch] from it. * app/core/* * app/tools/* * app/widgets/* * libgimpwidgets/*: started to use the glib object system. All core/ objects are still gtk objects however. All signals are created using g_signal_new(). There are many gtk+ artefacts left. Finally, we will _not_ use the gtk_signal_foo() wrappers and friends any more. * app/colormaps.c * app/devices.[ch] * app/disp_callbacks.c * app/errorconsole.c * app/file-save.[ch] * app/interface.c * app/module_db.c * app/nav_window.c * app/ops_buttons.c * app/scroll.c * app/user_install.c * app/gui/about-dialog.c * app/gui/brush-editor.c * app/gui/brushes-commands.c * app/gui/color-notebook.c * app/gui/colormap-dialog.c * app/gui/dialogs-commands.c * app/gui/dialogs-constructors.c * app/gui/file-commands.c * app/gui/file-dialog-utils.c * app/gui/file-new-dialog.c * app/gui/file-open-dialog.[ch] * app/gui/file-save-dialog.c * app/gui/gradient-editor.c * app/gui/gradients-commands.c * app/gui/image-commands.c * app/gui/info-dialog.[ch] * app/gui/layer-select.c * app/gui/layers-commands.c * app/gui/menus.c * app/gui/offset-dialog.c * app/gui/palette-editor.c * app/gui/palettes-commands.c * app/gui/patterns-commands.c * app/gui/preferences-dialog.c * app/gui/resize-dialog.[ch] * app/gui/splash.c * app/gui/tips-dialog.c * app/gui/tool-options-dialog.c * app/gui/toolbox.c * app/gui/tools-commands.c * libgimp/gimpbrushmenu.c * libgimp/gimpmenu.c * libgimp/gimppatternmenu.c * libgimp/gimpui.c * libgimpbase/gimpenv.c: tons and tons of changes like "const gchar*", switch from GdkDeviceInfo to GdkDevice (very incomplete and currently disables), lots of s/gtk_signal/g_signal/, removal/replacement of deprecated stuff, s/GtkSignalFunc/GCallback/ and lots of small changes and fixes while I was on it, zillions of warnings left... * modules/Makefile.am: disabled the water color selector temporarily (XInput issues). * plug-ins/Makefile.am * plug-ins/common/.cvsignore * plug-ins/common/Makefile.am * plug-ins/common/plugin-defs.pl: simply excluded all plug-ins which did not build (including Script-Fu). They are trivial to fix.
