gtk2/gtk/gtkctree.c
Lars Hamann 17d141c8e5 new class methods: (sort_list) (insert_row) (remove_row) 
Tue Aug 18 00:29:13 1998  Lars Hamann  <lars@gtk.org>

        * 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.
