From gal/menus: 2000-11-11 Christopher James Lahey <clahey@helixcode.com> * Makefile.am: Added gal-define-views-model.c, gal-define-views-model.h, gal-view-new-dialog.c, gal-view-new-dialog.h, gal-view-new-dialog.glade, gal-view-new-dialog.glade.h, gal-view.c, and gal-view.h. * gal-define-views-dialog.c, gal-define-views-dialog.h: Connect up the New button. Use an ETable. * gal-define-views.glade, gal-define-views.glade.h: Put in custom object for the ETable * gal-define-views-model.c, gal-define-views-model.h: New model for list of views. * gal-view-menus.c: Close the define views dialog when it's done. * gal-view-new-dialog.c, gal-view-new-dialog.glade, gal-view-new-dialog.glade.h, gal-view-new-dialog.h: New class for creating a new view. * gal-view.c, gal-view.h: New class for representing a single view in the define views model. svn path=/trunk/; revision=6544
