Rearranged SUBDIRS for dependencies.

2000-03-12  Christopher James Lahey  <clahey@helixcode.com>

        * widgets/Makefile.am: Rearranged SUBDIRS for dependencies.

        * widgets/e-text/e-text-model.c, widgets/e-text-model.h: New
        object which stores a piece of text data.  All methods are
        virtual.

        * widgets/e-text/e-text.c, widgets/e-text/e-text.h: Modified this
        to use an ETextModel for its data.

        * widgets/e-text/Makefile.am: Added e-text-model.c and e-text-model.h.

        * widgets/e-minicard/test-minicard-label.c: Made this work again.

        * widgets/e-minicard/e-minicard.c,
        widgets/e-minicard/e-minicard.h: Made this use an ETableModel to
        get its data.

        * widgets/e-minicard/e-minicard-label.c,
        widgets/e-minicard/e-minicard-label.h: Added the ability to set
        the text model used for the contained text widget.

        * widgets/e-minicard/Makefile.am: Added e-table since e-minicard
        is now dependent on an e-table-model for its data.

        * e-util/e-canvas.c, e-util/e-canvas.h: Fixed some bugs here to
        speed up reflow and to make it fail less often.

        * addressbook/demo, addressbook/demo/.cvsignore,
        addressbook/demo/Makefile.am, addressbook/demo/demo.c,
        addressbook/demo/spec: A new program to test ETable and EMinicard
        integration.

        * configure.in: Added addressbook/demo/Makefile.

        * addressbook/Makefile.am: Added the demo/ subdirectory.

in widgets/e-table/:

2000-03-12  Christopher James Lahey  <clahey@helixcode.com>

        * e-table.c: Made this use an ECanvas.  Fixed a bug where
        e_table_new_from_spec_file was calling e_table_construct instead
        of e_table_construct_from_spec_file.

        * e-table-item.c, e-table-header-item.c, e-table-column-item.c:
        Switched these to use GTK_TYPE_OBJECT and GTK_VALUE_OBJECT instead
        of GTK_TYPE_POINTER and GTK_TYPE_OBJECT.

        * e-cell-text.c: Got rid of a crashing bug.

        * e-table-text-model.c, e-table-text-model.h: A new object which
        is an e-text-model which uses an e-table-model for its data.

        * Makefile.am: Added e-table-text-model.c and
        e-table-text-model.h.

        * .cvsignore: Added table-example-1 and table-example-2.
