2004-07-07 Matthias Clasen <mclasen@redhat.com> Support separators in combo boxes and more generally in tree views (#135873): * gtk/gtkcombobox.h: * gtk/gtkcombobox.c (gtk_combo_box_get_row_separator_column): * gtk/gtkcombobox.c (gtk_combo_box_set_row_separator_column): Add a ::row-separator-column property with getter and setter, which can indicate a boolean model column to determine which rows are separators. * gtk/gtkcombobox.c: Display separator rows as separator menu items in menu mode, and by using the new treeview separator functionality in list mode. * gtk/gtktreeview.h: * gtk/gtktreeview.c (gtk_tree_view_get_row_separator_func): * gtk/gtktreeview.c (gtk_tree_view_set_row_separator_func): Add a callback to determine whether a row is a separator. * gtk/gtktreeview.c (gtk_tree_view_bin_expose): * gtk/gtktreeview.c (gtk_tree_view_create_row_drag_icon): * gtk/gtktreeview.c (validate_row): Use the new callback to determine whether a row is a separator, and draw it as a separator then. Since separators should take up less vertical space than regular rows, this requires removing the redundant MAX(...,expander_size) calls which appear in many places. Instead, the MAX() is now only done in validate_row(), and only if the row is not a separator. To catch possible side effects of this intrusive change, I have left EXPANDER_MAX() calls in place of the MAX() calls which will emit a warning if something breaks. They should be removed before 2.6. * gtk/gtktreeselection.c (row_is_selectable): Don't let separator rows be selected. * tests/testcombo.c (create_blaat): Add a separator column.
