2000-10-04 Not Zed <NotZed@HelixCode.com> * e-table-sorted-variable.c (etsv_add): Changed to take into account the sort group, if the table has one.x (etsv_insert_idle): Clear the insert count if we hit an idle loop. (etsv_sort_idle): Reset the insert count if we perform a sort. (etsv_add): If we are adding a lot (>ETSV_INSERT_MAX) items, without hitting an idle loop, assume we're better off performing a sort instead. Use another idle handler to reset the count. 2000-10-03 Not Zed <NotZed@HelixCode.com> * e-table-sorted-variable.c (etsv_sort_by_group): Sort based on the sort_group stuff. * e-tree-model.c (e_tree_init): Setup the group sort info string. (etree_destroy): And free it. (build_sort_group): Build a string for this node. 2000-09-29 Not Zed <NotZed@HelixCode.com> * e-cell-tree.c (e_cell_tree_get_node): Changed to take the source model, not the tree model. The source model may be a subset, and it needs to remap the rows for us. (ect_draw): (ect_event): (ect_max_width): (ect_print): Changed callers. * e-table-sorted-variable.c (etsv_sort_subset): (etsv_sort_build_subset): (etsv_sort_free_subset): Functions to perfom grouping of sorts for sorts that have row_sort_group returning useful info. (etsv_sort): Use the complex sort routines if we need to. * e-table-model.c (e_table_model_row_sort_group): Return a sort-id for a given row. (e_table_model_has_sort_group): Return if the sort-id provides any useful information. svn path=/trunk/; revision=5705
