From 77df46c366a3b761288db21b2593e963c4590207 Mon Sep 17 00:00:00 2001 From: Miguel de Icaza Date: Sat, 20 Nov 1999 23:37:37 +0000 Subject: Compute width, keep track of it. (ethi_add_table_header): Monitor changes 1999-11-20 Miguel de Icaza * 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.
