Compute width, keep track of it. (ethi_add_table_header): Monitor changes
1999-11-20 Miguel de Icaza <miguel@gnu.org> * e-table-header-item.c (ethi_set_arg): Compute width, keep track of it. (ethi_add_table_header): Monitor changes to the Header model; Queue updates. (ethi_draw): Fix the redraw logic here. * table-test.c (main): Change the sample code, so we can better debug this. * e-table-item.c (eti_header_structure_changed): Keep track of width; (eti_header_dim_changed): ditto. (eti_draw): Many redraw fixes. svn path=/trunk/; revision=1425
