Instead store all the specific text attributes. Separate whether an attribute is enabled from its value. Sync all properties with GtkTextTag, make them all consistent, etc. * gtk/gtkcellrenderer.h: Add a flag GTK_CELL_RENDERER_SORTED so renderers can highlight the sort row/column * gtk/gtktreeviewcolumn.c (gtk_tree_view_column_get_property): use accessor functions to get values; this has the side effect of showing up which accessor functions were missing. Added those. * gtk/gtktreeviewcolumn.h: Replace set_justification with set_alignment, to be consistent with GtkLabel, GtkMisc * gtk/gtktreeviewcolumn.c: Added code to display sort indicator arrow. * gtk/Makefile.am (gtk_public_h_sources): add gtktreesortable.h * gtk/gtktreesortable.h: updates in here

Adapt to GtkTreeSelection changes 2001-01-01 Havoc Pennington <hp@redhat.com> * gtk/gtktreeview.c: Adapt to GtkTreeSelection changes * gtk/gtktreeselection.c (_gtk_tree_selection_set_tree_view): don't fill in tree_view->priv->selection, kind of an unexpected side effect * gtk/gtkcellrenderertext.c: Remove definition of _ and include gtkintl.h * gtk/gtkcellrenderer.c: Remove definition of _ and include gtkintl.h (gtk_cell_renderer_get_property): remove calls to g_value_init * gtk/gtkcellrendererpixbuf.c: Remove definition of _ and include gtkintl.h * gtk/gtkcellrenderertextpixbuf.c: Remove definition of _ macro and include gtkintl.h (gtk_cell_renderer_text_pixbuf_class_init): remove spaces from property names * gtk/gtktreeselection.c (_gtk_tree_selection_new): rename, return GtkTreeSelection (_gtk_tree_selection_new_from_with_view): rename, return GtkTreeSelection (_gtk_tree_selection_set_tree_view): rename with uscore (gtk_tree_selection_get_selected): fill in the "model" out param first, so it gets filled in even if we return at the top of the function (gtk_tree_selection_real_select_all): add a comment and an else{} to clarify this a bit (gtk_tree_selection_real_unselect_all): add the same else{} * gtk/gtktreeselection.h: Rename new, new_with_tree_view, and set_tree_view to have underscore prefixes, move them to the private header, fix return type of new_with_tree_view (struct _GtkTreeSelection): mark struct fields private * gtk/gtktreemodel.c (gtk_tree_model_get_flags): return GtkTreeModelFlags, not a guint (gtk_tree_path_prev): return gboolean not gint (gtk_tree_path_up): return gboolean not gint * gtk/gtktreemodel.h (struct _GtkTreeModelIface): make get_flags return GtkTreeModelFlags, not a guint * gtk/gtktreemodelsort.c (gtk_tree_model_sort_finalize): check that child model is non-null before unrefing it (g_value_int_compare_func): make this a qsort compare func, not a boolean predicate * gtk/gtktreemodelsort.h: rename gtk_tree_model_set_sort_column, (add -umn to the end), and mark it unimplemented (gtk_tree_model_sort_resort): remove, this wasn't implemented, and I don't see what it's for - doesn't the model always sort itself? (gtk_tree_model_sort_set_compare): this had the wrong signature * gtk/gtktreeviewcolumn.c (gtk_tree_view_column_set_attributes): Fix the docs to say that it destructively replaces existing attributes (previously said that it added attributes). (gtk_tree_view_column_set_visible): canonicalize bool before equality testing. Also, check for realization before hiding/showing the tree_column->window; if this window could exist before realization, then it's busted and needs fixing, we can't create GDK resources pre-realization. Also, remove superfluous queue_resize(), since set_size() does that for us. (gtk_tree_view_column_set_col_type): check realization before using tree_column->window * gtk/gtktreedatalist.c: fix filename in copyright notice
