2004-06-15 Michael Natterer <mitch@gimp.org> * app/actions/Makefile.am * app/actions/context-actions.[ch] * app/actions/context-commands.[ch]: added new action group to modify all GimpContext properties. So far there are actions to cycle through the lists of brushes, patterns etc., to change the opacity, to swap and default colors and to edit generated brushes. * app/actions/actions.c: register the new "context" action group. * app/actions/tools-actions.c * app/actions/tools-commands.[ch]: removed "tools-default-colors" and "tools-swap-colors" actions and callbacks because they are in the "context" action group now. * app/menus/menus.c: add the "context" group to the <Image> and <Dock> UI managers. * menus/image-menu.xml.in: changed accordingly. Added a temporary "Context" menu to test and debug the new actions.
