2001-06-26 Michael Natterer <mitch@gimp.org> * app/Makefile.am * app/color_transfer.[ch]: removed. * app/tools/Makefile.am * app/tools/gimpcolorbalancetool-transfer.[ch]: added. * app/tools/gimpcolorbalancetool.c: changed accordingly. * app/base/Makefile.am * app/base/tile-manager-crop.[ch]: formerly known as crop_buffer(). * app/tools/gimptexttool.c: changed accordingly. * app/context_manager.[ch]: added the global clipboard and the named buffer list here. * app/app_procs.c: don't call color_transfer_init() and don't free the buffer stuff (done by the context manager now). * app/errorconsole.c: don't #include "gui/commands.h" * app/global_edit.[ch]: removed lots of stuff which is now done by gui/edit-commands.* or the new GimpBuffer object. The "paste named" dialog will go away and this file will be moved to core/ soon. * app/image_new.c: no need to declare the global_buffer extern any more. * app/qmask.c: don't #include "global_edit.h" * app/core/Makefile.am * app/core/core-types.h * app/core/gimpbuffer.[ch]: new object (aka named buffer) * app/core/gimpcontext.[ch]: added a GimpBuffer attribute. * app/core/gimpimage.[ch]: one s/int/gboolean/. * app/core/gimppattern.c: hmm... * app/gui/commands.[ch]: split up in small files: * app/gui/Makefile.am * app/gui/edit-commands.[ch] * app/gui/file-commands.[ch] * app/gui/image-commands.[ch] * app/gui/select-commands.[ch] * app/gui/view-commands.[ch]: new files. * app/gui/dialogs-constructors.[ch] * app/gui/dialogs.c: added the named buffer list & grid. * app/gui/file-new-dialog.[ch] * app/gui/menus.c * app/gui/palette-editor.c * app/gui/test-commands.c: changed accordingly. * app/pdb/edit_cmds.c * tools/pdbgen/pdb/edit.pdb: changed for the global_edit stuff. * app/widgets/Makefile.am * app/widgets/gimpbufferpreview.[ch] * app/widgets/gimpbufferview.[ch] * app/widgets/gimpcontainereditor.[ch]: new widgets. * app/widgets/gimpcontainerview-utils.c * app/widgets/gimpdatafactoryview.[ch] * app/widgets/gimpdnd.[ch] * app/widgets/gimpdrawablepreview.c * app/widgets/gimplayerlistview.c * app/widgets/gimppreview.c * app/widgets/widgets-types.h: changed accordingly for the new GimpBuffer object and it's views, misc. cleanups. * pixmaps/Makefile.am * pixmaps/paste-as-new.xpm * pixmaps/paste-into.xpm * pixmaps/paste.xpm: new pixmaps (they all look the same... Tigert? ;-) * po/POTFILES.in: added the new files.
