Implement bookmark renaming (#136216, Sean Middleditch)
* gtk/gtkfilesystem.h (struct _GtkFileSystemIface): Add
get_bookmark_label and set_bookmark_label vfuncs.
* gtk/gtkfilesystem.h:
* gtk/gtkfilesystem.c (gtk_file_system_set_bookmark_label):
(gtk_file_system_get_bookmark_label): Wrappers for the
vfuncs.
* gtk/gtk.symbols: Add new exported symbols.
* gtk/gtkfilesystemunix.c (gtk_file_system_unix_set_bookmark_label):
(gtk_file_system_unix_get_bookmark_label): Implementations
for the Unix backend.
* gtk/gtkfilechooserdefault.c: Add a context menu to
the bookmarks pane, and allow to rename bookmarks.
2005-01-02 Tor Lillqvist <tml@iki.fi>
* gtk/Makefile.am (libgtk_target_ldflags): Add -lole32, needed for
CoTaskMemFree in get_special_folder() below.
* gtk/gtkfilesystem.h: Implement case-insensitive path compare on
Win32 using _gtk_file_system_win32_path_compare().
* gtk/gtk.symbols: Add _gtk_file_system_win32_path_compare.
* gtk/gtkfilechooserbutton.c (model_add_special)
* gtk/gtkfilechooserdefault.c (shortcuts_append_desktop): Use
_gtk_file_system_win32_get_desktop() to get correct Desktop folder
on Win32. (#144003)
* gtk/gtkfilesystemwin32.c: Remove unnecessary includes. Do
consider all drives "mounted", including floppies. Trying to
inspect the contents of a nonexistent floppy will cause errors
later that are handled normally, no need to avoid them
completely. Keep the drive type in the GtkFileSystemVolume.
Support UNC paths. (#161797) Fix error message capitalizations
as in gtkfilesystemunix.c.
(gtk_file_system_win32_init): Start one timeout per
GtkFileSystemWin32.
(gtk_file_system_win32_finalize): Remove the timeout.
(get_special_folder): Copied from GLib.
(_gtk_file_system_win32_get_desktop): New function, uses
get_special_folder().
(gtk_file_system_win32_list_volumes): Don't start a timeout at
each call to this function. Don't assume A: and B: are floppies.
(gtk_file_system_win32_get_volume_for_path): Don't assume all
volumes are drive roots, i.e. support share roots of UNC paths
(\\server\share).
(gtk_file_system_win32_get_folder): Don't assume errno is set
after g_file_test() returns FALSE. It isn't on Win32 (and even on
Unix I don't think one should assume anything about errno after
g_file_test()).
(gtk_file_system_win32_volume_get_is_mounted): Always return TRUE.
(gtk_file_system_win32_volume_get_display_name): Don't call
GetVolumeInformation() on drives A: or B: if they are removable,
as they might then be floppies, causing an unnecessary
delay. (#157820)
(gtk_file_system_win32_volume_render_icon): Use network icon for
unrecognized drive types.
(canonicalize_filename, gtk_file_system_win32_parse): Don't get
confused by UNC paths.
(bookmarks_serialize): Use _gtk_file_system_win32_path_compare()
for case-insensitive UTF-8 path comparison.
(extract_icon): Use SHGetFileInfo() which is faster than
ExtractAssociatedIcon(). Icon extraction is still slow, though,
needs work.
(win32_pseudo_mime_lookup): Don't use the same icon for all
shortcuts or executables. Cache only other file type icons.
(gtk_file_system_win32_render_icon): Use network stock icon for
remote drives and UNC server share roots. Compare home directory
case-insensitively. Do lookup icons also for executable files,
after all, it's these files that can have individual icons in the
first place. Yes, it can be slow. Needs work.
(filename_is_drive_root): Require also the slash after the colon.
(filename_is_server_share): New function.
(_gtk_file_system_win32_path_compare): New function, does
case-folded UTF-8 comparison.
* gtk/gtkfilesystemwin32.h: Declare
_gtk_file_system_win32_path_compare().
2004-09-18 Federico Mena Quintero <federico@ximian.com>
Merged from 2.4:
* gtk/gtkfilesystem.h: Removed the GTK_FILE_PATH() and
GTK_IS_FILE_PATH() macros. They are not supposed to exist, as
GtkFilePath is not an object. And they never worked, anyway.
2004-03-29 Federico Mena Quintero <federico@ximian.com>
Fix#137520.
* gtk/gtkfilesystem.h (struct _GtkFileFolderIface): Added slots

connect to the signal.
(_gtk_file_system_model_new): Connect to the normal signals of the
folder even if the initial _list_children() fails. Also, see if
the folder is finished loading; connect to the "finished-loading"
signal otherwise.
(gtk_file_system_model_finalize): Remove the idle handler.
* gtk/gtkfilechooserdefault.c (set_list_model): Set a busy cursor
and connect to the model's "finished-loading" signal.
(get_toplevel): New helper function.
(error_message): Use get_toplevel().
(trap_activate_cb): Likewise.

(set_busy_cursor): New function.
(browse_files_model_finished_loading_cb): New callback.
2004-03-19 Federico Mena Quintero <federico@ximian.com>
* Revert the patch to #137520, as 2.4.1 is for conservative bug
fixes only. The patch is attached to the bug report, for
reference.

FilePath.

path does not exist in the bookmarks list.
* gtk/gtkfilechooserdefault.c (shortcuts_add_bookmark_from_path):
For now, use gtk_file_system_insert_bookmark() with -1 for the
position. DnD will come next.
