Hi,
I've been having some great luck using a GtkListStore, but recently I
wanted to see the previous node on the list. Obviously, the
gtk_tree_model_iter_prev doesn't exist. So what is the best way to get
the previous node.
I tried something like the code below, but path was always NULL and so
it didn't work. Any hints on this?
// global
GtkListStore *playliststore;
GtkTreeIter iter;
// in the callback
GtkTreePath *path;
gchar *filename;
gint count;
gint playlist;
path = gtk_tree_model_get_path(GTK_TREE_MODEL(playliststore),&iter);
if (gtk_tree_path_prev(path)) {
if(gtk_tree_model_get_iter(GTK_TREE_MODEL(playliststore),&iter,path)) {
gtk_tree_model_get(GTK_TREE_MODEL(playliststore), &iter,
ITEM_COLUMN,&filename, COUNT_COLUMN,&count,PLAYLIST_COLUMN,&playlist,-1);
shutdown();
set_media_info(filename);
play_file(filename, playlist);
gtk_list_store_set(playliststore,&iter,COUNT_COLUMN,count+1, -1);
g_free(filename);
}
}
gtk_tree_path_free(path);
Thanks,
Kevin
