Port to glib/gtk+ 2.0 episode I (every segfault has it's beginning) 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.

an evil temp_hack which lets GimpContext managing the active display 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.

This is no longer possible because the libgimpui headers don't inlcude "libgimp/gimpunit.h" any more.
