2001-11-27 Michael Natterer <mitch@gimp.org> * app/core/gimpcontainer.c: GType is a pointer now, not a guint. * app/widgets/gimpdock.c: chain up in widget_class->style_set(). Gradient Editor chopping plus merging of bex' proofreading: (fixes #62278). * app/core/core-types.h: moved the gradient related enums here. * app/core/gimpgradient.[ch]: removed the enums, added gradient segment utility functions from the gradient_editor. * app/gui/gui-types.h: added the GradientEditor typedef here. * app/gui/Makefile.am * app/gui/gradient-editor-commands.[ch]: new files implementing callbacks and menu_update stuff for the new gradient_editor item factory. * app/gui/gradient-editor.[ch]: removed tons of code, namespace cleanup, stuff... * app/gui/menus.[ch]: added the gradient_editor menu stuff here. Added menus_set_color() which creates & updates a color menu item (will soon be used in other places too). Renamed menus_set_state() to menus_set_active(). The editor's menu code is ugly as before, only different and evil the same way as the rest of the menu stuff, so it's at least consistent :) * app/display/gimpdisplayshell.c: changed accordingly. * app/gui/test-commands.c: don't include "gradient-editor.h".
