2008-06-16 Ross Burton <ross@burtonini.com> Bug 536252 – GFileEnumerator should allow access to the containing GFile * gio/gfileenumerator.c: * gio/gfileenumerator.h: * gio/gfile.h: Add g_file_enumerator_get_container() and a container writeable construct-only property. Also shuffle around typedefs to make it compile. * gio/glocalfileenumerator.c: * gio/glocalfileenumerator.h: * gio/glocalfile.c: Instead of a string filename take a GFile in the constructor and use it to set the container property. * gio/gio.symbols: * docs/reference/gio/gio-sections.txt: Update with new API. svn path=/trunk/; revision=7044
