2001-02-18 Michael Natterer <mitch@gimp.org> * app/gimpdnd.[ch]: added DND source functions which work by GtkType. * app/commands.c * app/brush_select.c * app/gradient_select.[ch] * app/pattern_select.c: removed the DND code here because it's all done by the GimpContainerView now. * app/gimpbrushpreview.c * app/gimpgradientpreview.c * app/gimppalettepreview.c * app/gimppatternpreview.c: use the DND by-type connect functions. * app/gimpbrushgenerated.c: implemented "duplicate", cleanup. * app/gimpcontainergridview.c * app/gimpcontainerlistview.c * app/gimpcontainerview.[ch]: added a "activate_item" signal method which is emitted by the subclasses to indicate double click. * app/gimpdatafactoryview.c: connect to "activate_item" and show the editor. * app/convert.c * app/gimppalette.[ch] * app/palette.c * app/paletteP.h * app/palette_import.c * app/palette_select.[ch]: major cleanup: Behaves like the other datatypes now: DND, context stuff, GimpContainerListViews in the dialogs etc. Mostly just removal of code. * app/gradient_editor.c: fixed signal blocking/unblocking. * plug-ins/script-fu/scripts/Makefile.am: install the "Test Sphere" script again.
