2004-04-22 Tor Lillqvist <tml@iki.fi> Fix the file chooser on Windows. I can't make it misbehave or crash any more now. But presumably there are still corner cases not handled. I haven't really checked behaviour of UNC paths, for instance. * gtk/gtkfilesystemwin32.c: Accept both backslash and slash in several places. Use G_IS_DIR_SEPARATOR macro (which could be added to GLib in 2.6). (gtk_file_system_win32_get_parent): Like the Unix version, assert filename is absolute, and avoid one unnecessary string allocation and freeing. (canonicalize_filename,gtk_file_system_win32_parse): Handle drive letters more correctly. (gtk_file_system_win32_render_icon): Assure correct syntax is used for root folder of a drive. (#137962, Morten Welinder) (filename_is_some_root): New function that accepts also root without any drive specified. (filename_is_drive_root): Rename from filename_is_root. * gtk/gtkfilechooserentry.c (completion_match_func): Casefold on Windows.
