Insert an item after the specified item
void PtFSAddAfter( PtWidget_t *fs, PtFileSelItem_t *item, PtFileSelItem_t *brother );
This function inserts a list of items linked with the brother field. PtFSAddAfter() assumes that item points to a list of items. The fs variable points to a PtFileSel widget. The new items are added to the specified file selector below the specified brother.
You can call this function with a NULL fs argument, as long as brother points to an item that isn't attached to any file selector widget.
