2001-05-07 Christopher James Lahey <clahey@ximian.com> * gal/Makefile.am (libgal_la_LIBADD): Added util/e-sorter-array.lo and widgets/e-reflow-model.lo. Removed widgets/e-reflow-sorted.lo. * gal/util/Makefile.am (libutil_la_SOURCES): Added e-sorter-array.c. (libgalinclude_HEADERS): Added e-sorter-array.h. * gal/util/e-sorter-array.c, gal/util/e-sorter-array.h: A sorter for use with a single compare function to do sorting. * gal/util/e-util.c, gal/util/e-util.h (e_marshal_INT__OBJECT_POINTER): Added this marshaller. * gal/widgets/Makefile.am (libwidgets_la_SOURCES): Added e-reflow-model.c. Removed e-reflow-sorted.c. (libwidgetsinclude_HEADERS): Added e-reflow-sorted.h. Removed e-reflow-model.h. * gal/widgets/e-reflow-model.c, gal/widgets/e-reflow-model.h: Model for EReflow. Has a number of items and generates canvas items on the fly. * gal/widgets/e-reflow.c, gal/widgets/e-reflow.h: Major rewrite. This now uses a model to generate its canvas items instead of having canvas items added to it. It doesn't create the canvas items now until they will be shown on screen. svn path=/trunk/; revision=9710
