* gtk/gtkclist.h:
(struct _GtkCListClass): new class methods:
(sort_list) (insert_row) (remove_row) (set_cell_contents)
* gtk/gtkclist.c :
(cell_empty) (cell_set_text) (cell_set_pixmap) (cell_set_pixtext):
removed and replaced by (set_cell_contents)
(set_cell_contents): function for class method set_cell_contents
(real_insert_row): function for class method insert_row
(real_remoce_row): function for class method remove_row
(real_sort_list): function for class method sort_list
(default_compare): fix to avoid problems with cell types != CELL_TEXT
* gtk/gtkctree.h :
(gtk_ctree_export_to_gnode): new function to export a ctree as gnode
(gtk_ctree_node_is_visible): new function to return visibility state
of a node
(gtk_ctree_show_stub): new function to set visibility of root stub
renamed functions :
(gtk_ctree_insert) -> (gtk_ctree_insert_node)
(gtk_ctree_remove) -> (gtk_ctree_remove_node)
(gtk_ctree_find_glist_ptr) -> (gtk_ctree_find_node_ptr)
(gtk_ctree_set_text) -> (gtk_ctree_node_set_text)
(gtk_ctree_set_pixmap) -> (gtk_ctree_node_set_pixmap)
(gtk_ctree_set_pixtext) -> (gtk_ctree_node_set_pixtext)
(gtk_ctree_set_shift) -> (gtk_ctree_node_set_shift)
(gtk_ctree_get_cell_type) -> (gtk_ctree_node_get_cell_type)
(gtk_ctree_get_text) -> (gtk_ctree_node_get_text)
(gtk_ctree_get_pixmap) -> (gtk_ctree_node_get_pixmap)
(gtk_ctree_get_pixtext) -> (gtk_ctree_node_get_pixtext)
(gtk_ctree_set_foreground) -> (gtk_ctree_node_set_foreground)
(gtk_ctree_set_background) -> (gtk_ctree_node_set_background)
(gtk_ctree_set_row_data) -> (gtk_ctree_node_set_row_data)
(gtk_ctree_set_row_data_full) -> (gtk_ctree_node_set_row_data_full)
(gtk_ctree_get_row_data) -> (gtk_ctree_node_get_row_data)
(gtk_ctree_moveto) -> (gtk_ctree_node_moveto)
(gtk_ctree_sort) -> (gtk_ctree_sort_node)
(gtk_ctree_is_visibe) -> (gtk_ctree_is_viewable)
* gtk/gtkctree.c :
(cell_empty) (cell_set_text) (cell_set_pixmap) (cell_set_pixtext):
removed and replaced by (set_cell_contents)
(set_cell_contents): function for class method set_cell_contents
(real_insert_row): function for class method insert_row
(real_remoce_row): function for class method remove_row
(real_sort_list): function for class method sort_list
(default_compare): removed. CTree now also compares two GtkCTreeRows
instead of two GtkCTreeNodes.
(gtk_ctree_unlink): call gtk_ctree_collapse if parent is empty after
unlinking the node
(real_tree_expand) (real_tree_collapse): fix for refcounting of
node pixmaps
(set_node_info): call gtk_ctree_node_set_pixtext instead of
manipulating the row itself
* gtk/testgtk.c: use renamed functions of GtkCTree.
new sample to show gtk_ctree_export_to_gnode and gtk_ctree_insert_gnode
at work.
