2004-01-29 Michael Natterer <mitch@gimp.org> * app/core/gimpcontext.[ch]: removed the last artefact of context signal handling from 1.2: GimpContext used to connect to e.g. the current brush's "invalidate_preview" and "name_changed" signals and emitted "brush_changed" when the callback was invoked. This was needed to make 1.2 work, but is conceptually broken with the real model <-> view approach implemented in the current code. This change also optimizes things quite a bit because lots of signal emissions are saved. Added utility function which finds a container's current object after a freeze/thaw. * app/widgets/gimpcontainerview.[ch]: added new virtual function GimpContainerView::rename_item(). Connect to "name_changed" of the corrent container's children and invoke rename_item() accordingly. * app/widgets/gimpcontainertreeview.[ch]: removed name_changed handler and implement GimpContainerView::rename_item(). * app/widgets/gimpcontainergridview.c: ditto. the grid view was still relying on the removed GimpContext behaviour for updating the label showing the sleected item's name.
