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.
