* gtk/gtkfilechooserdefault.c (save_entry_get_info_cb),
(file_exists_get_info_cb), (gtk_file_chooser_default_should_respond):
change file_exists_and_is_not_folder checks to get the file info
for the path directly instead of querying the current file folder
of the save entry.
* gtk/gtkfilechooserprivate.h (struct _GtkFileChooserDefault): add
new field.
* tests/autotestfilechooser.c (wait_for_idle_idle), (wait_for_idle),
(test_reload_sequence), (test_button_folder_states_for_action): wait
for idle after setting a folder to ensure the async operations to load
the folder are finished,
(test_confirm_overwrite), (test_confirm_overwrite_for_path):
factor out test_confirm_overwrite code so we can add tests for more
paths more easily.
Tue Aug 29 11:57:40 2006 Tim Janik <timj@imendio.com>
* tests/testgtk.c: allow (most) windows to be resizable.
added ellipsization settings to progress bars.
2006-08-28 Michael Natterer <mitch@imendio.com>
* gtk/gtktextbufferserialize.c (serialize_text): don't write out
</apply_tag> for tags that have already been closed by the logic
which turns overlapping spans into XML-able trees. Fixes broken
XML when there are overlapping tags in the buffer. Also free two
leaked GLists and did some cleanup.
* tests/Makefile.am
* tests/testrichtext.c: new test which creates randomly tagged
GtkTextBuffers and serializes/deserializes them.
2006-08-23 Federico Mena Quintero <federico@novell.com>
* gtk/gtkfilesystem.[ch] (_gtk_file_system_create): Renamed to
gtk_file_system_create() so that it will get exported and we can
use it in the test program.
* gtk/gtk.symbols: Added gtk_file_system_create.
* gtk/gtkfilechooserdefault.c (set_file_system_backend): Use
gtk_file_system_create().
* tests/autotestfilesystem.c: New file with automatic tests for
the async callbacks and cancelation policy of GtkFileSystem.
* tests/Makefile.am: Added autotestfilesystem.
2006-08-17 Federico Mena Quintero <federico@novell.com>
* gtk/gtkfilechooserdefault.c
(_gtk_file_chooser_default_class_init): Enable "/" and "~" as
bindings to activate the location entry again. Fixes bug #340856.
(tree_view_keybinding_cb): Likewise.
(trap_activate_cb): Likewise.
(location_popup_handler): Handle the "path" argument again; set it
as the text on the location entry.
(location_set_user_text): New helper function.
(load_setup_timer): Fix comment.
* tests/autotestfilechooser.c (main): Oops, enable all the tests again.
2006-08-17 Paolo Borelli <pborelli@katamail.com>
* gtk/gtktextbuffer.c: make sure the has-selection property is
updated when the delection is deleted. Bug #329752
* tests/testtext.c: add a copy menu item and show how to
update its sensitivity tracking the has-selection property.
2006-08-06 Matthias Clasen <mclasen@redhat.com>
* gtk/gtknotebook.c (gtk_notebook_drag_motion): Don't allow
dragging a notebook tab to one of its children. (#348626,
Benjamin Otte)
2006-07-19 Federico Mena Quintero <federico@novell.com>
* tests/autotestfilechooser.c (test_black_box): Argh, initialize
"passed"!
(set_filename_timeout_cb): Renamed from timeout_cb().
(test_confirm_overwrite): New function, test confirmation before
overwriting a file in SAVE mode.
2006-07-18 Federico Mena Quintero <federico@novell.com>
Fix https://bugzilla.novell.com/show_bug.cgi?id=184875 - make the
location entry in Save mode preserve the stuff from
set_filename(); it was overwriting it with $cwd.
This is the same fix for
http://bugzilla.gnome.org/show_bug.cgi?id=347066
* tests/autotestfilechooser.c: (test_black_box): Added black-box
test for set_filename() and set_current_name().
* gtk/gtkfilechooser.c (gtk_file_chooser_get_type): Cast to
GClassInitFunc in the call to g_type_register_static_simple(), to
avoid a compiler warning.
* gtk/gtkfilechooserprivate.h (struct _GtkFileChooserDefault):
Added a browse_files_last_selected_name field. We'll copy the
logic from gtkfilesel.c to see when to clear the location entry.
(struct _GtkFileChooserDefault): Removed the
processing_pending_selections field.
* gtk/gtkfilechooserdefault.c (gtk_file_chooser_default_finalize):
Free impl->browse_files_last_selected_name.
(pending_select_paths_process): Don't use
impl->processing_pending_selections.
(update_chooser_entry): Keep track of the name that was last
selected in the file list. We use this to know when to clear the
location entry. The logic is similar to that of
gtkfilesel.c:gtk_file_selection_file_changed(). This also lets us
get rid of the processing_pending_selections flag.
(update_chooser_entry): Clear the entry if we didn't have a
selection before.
(location_switch_to_filename_entry): Do not set $cwd as the
contents of the location entry here...
(location_popup_handler): ... but do it here instead, only as the
result of the user asking to turn on the location entry.
(gtk_file_chooser_default_get_paths): If the location entry is
empty, do the fallback of seeing if it is sensible to say that
$cwd is the selected path.
(gtk_file_chooser_default_update_current_folder): Don't set the
text of the location entry; this is no longer needed with the
fixes above.
(shortcuts_activate_iter): Clear the location entry when
activating a shortcut if we are not in SAVE mode. This keeps the
contents of the location entry consistent even when switching
folders via the shortcuts.

2006-05-03 Federico Mena Quintero <federico@novell.com>
Merged the federico-filename-entry branch, to fix bug #136541.
Combined ChangeLogs:
2006-04-17 Federico Mena Quintero <federico@novell.com>
* gtk/gtkfilechooserdefault.c (pending_select_paths_process):
Oops, we *do* need to check that we are in OPEN mode before
selecting the first row in the file list. See
https://bugzilla.novell.com/show_bug.cgi?id=166906
(gtk_file_chooser_default_get_paths): If we are in the case for
the file list, and the list has no selected rows, jump to the case
for the filename entry. This is so that
1. The user types a filename in the SAVE filename entry
("foo.txt").
2. He then double-clicks on a folder ("bar") in the file
list.
will yield the expected "bar/foo.txt" selection.
2006-03-29 Federico Mena Quintero <federico@novell.com>
* gtk/gtkpathbar.c (gtk_path_bar_init): Reduce the inter-button
spacing to 0.
* gtk/gtkfilechooserdefault.c (browse_widgets_create): Make the
location label bold.
2006-03-29 Federico Mena Quintero <federico@novell.com>
* gtk/gtkfilechooserdefault.c (location_mode_set): Just change the
location_mode field if we are in SAVE/CREATE_FOLDER modes.
(gtk_file_chooser_default_get_paths): Get the path based on the
currently focused widget, or the last-focused widget. This is
what we should have been doing in the beginning, but it worked out
fine because we didn't have the possibility of a filename entry in
OPEN mode.
(gtk_file_chooser_default_should_respond): Handle the case where
the last focused widget is the location_entry.
2006-03-28 Federico Mena Quintero <federico@novell.com>
* gtk/gtkfilechoosersettings.[ch]: New files with a simple
framework for saving/loading settings from the file chooser in
$XDG_CONFIG_HOME/gtk-2.0/gtkfilechooser.
* gtk/gtkfilechooserdefault.c (gtk_file_chooser_default_unmap):
Save the current settings.
(settings_save): New helper function. We save the location_mode
and show_hidden flags.
(gtk_file_chooser_default_map): Load the settings.
(settings_load): New helper function.
* gtk/gtkfilechooserentry.c
(_gtk_file_chooser_entry_set_file_part): Oops, don't modify
in_change. Our handlers are what set the file_part, so they
*must* be run when we modify the text.
2006-03-27 Federico Mena Quintero <federico@novell.com>
* gtk/gtkfilechooserprivate.h (struct _GtkFileChooserDefault):
Removed the save_file_name_entry. We'll make this be the same as
the location_entry widget.
(struct _GtkFileChooserDefault): Leave only location_button,
location_entry_box, location_label, location_entry. We'll use a
single toggle button for the location entry, which will appear
below the path bar.
(struct _GtkFileChooserDefault): Added a
processing_pending_selections flag.
* gtk/gtkfilechooserdefault.c (save_widgets_create): Destroy the
old location_entry if necessary, and hide the location toggle
widgets.
(update_chooser_entry): In multiple selection mode, just clear the
location_entry.
(check_save_entry): Allow running in OPEN or SELECT_FOLDER modes
if we are in LOCATION_MODE_FILENAME_ENTRY.
(gtk_file_chooser_default_should_respond): Switch to a folder if
the location_entry contains a folder name in OPEN and SAVE mode,
not just SAVE mode. If the entry doesn't contain a folder name,
but is otherwise well-formed, and we are in OPEN mode, return that
we should respond with that filename.
(gtk_file_chooser_default_initial_focus): Focus the location_entry
if appropriate.
(browse_widgets_create): Create the location_entry_box and the
location_label here.
(update_appearance): Call location_mode_set() when switching back
to OPEN/SELECT_FOLDER mode. Hide the location_button when
switching to SAVE/CREATE_FOLDER mode.
(pending_select_paths_process): Turn the
processing_pending_selections flag on and off around changes to
the current selection. Don't special-case OPEN mode anymore,
since the new flag will take care of things in
update_chooser_entry().
(update_chooser_entry): Don't do anything if
processing_pending_selections is TRUE. This keeps the entry from
being polluted when changing folders.
(location_popup_handler): In OPEN/SELECT_FOLDER modes, toggle
between the path bar and the entry. In SAVE/CREATE_FOLDER modes, simply focus the
location_entry.
(update_from_entry): Removed.
(location_entry_create): Removed.
(open_location_cb): Removed.
(file_list_build_popup_menu): Don't add an "Open _Location" menu item.
(location_entry_set_initial_text): Don't do anything if
current_folder is NULL.
* gtk/gtkfilechooserentry.c
(_gtk_file_chooser_entry_set_file_part): Turn in_change on and off
around the call to gtk_entry_set_text(). This makes completion
not happen when the caller has explicitly set a name.
2006-03-24 Federico Mena Quintero <federico@novell.com>
* gtk/gtkfilechooserprivate.h (struct _GtkFileChooserDefault):
Added fields location_mode_box, location_pathbar_radio,
location_filename_radio, location_widget_box, location_label,
location_entry. The radio buttons will switch between the pathbar
and the location entry; the other boxes are for layout purposes.
(enum LocationMode): New enum.
(struct _GtkFileChooserDefault): Added a location_mode field.
* gtk/gtkfilechooserdefault.c (browse_widgets_create): Create the
location radio buttons to switch between the pathbar and the
location entry. Pack the browse_path_bar in the new
location_widget_box instead of a generic hbox.
(location_buttons_create): New function.
(gtk_file_chooser_default_init): Initialize impl->location_mode.
(location_switch_to_path_bar): New function.
(location_switch_to_filename_entry): New function.
* gtk/gtkfilechooserbutton.c (model_add_special): The display_name
should not be const.

bitfield, otherwise set this field to normal. Set the private
field to the type hint.
* gtk/gtkwindow.c (gtk_window_init): Initialize priv->type_hint.
* gtk/gtkwindow.c (struct _GtkWindowPrivate): New field
"reset_type_hint" indicating whether the type hint needs to be

propagate changes in composited status.
(gtk_widget_class_init): Add composited_changed signal.
* gtk/gtkwidget.h (struct _GtkWidgetClass): New signal composited-changed.

(#318761, Ross Burton)
2006-03-08 Carlos Garnacho <carlosg@gnome.org>
Rename ::tab-added and ::tab-removed signals to ::page-added and
::page-removed for not conflicting with other tab reordering
implementations. Fixes bug #333743.
Also rename ::tab-reordered to ::page-reordered, and emit it in
gtk_notebook_reorder_child () to make it behave consistently with the
other two signals.
* gtk/gtknotebook.c (gtk_notebook_class_init): rename signals.
(gtk_notebook_reorder_tab)
(gtk_notebook_button_release)
(gtk_notebook_remove)

2006-03-07 Michael Natterer <mitch@imendio.com>
Add infrastructure for copy/paste and DND of rich text for
GtkTextBuffer. Fixes bug #324177.
* gtk/gtktextbufferrichtext.[ch]: new files implementing a
per-buffer registry of rich text formats.
* gtk/gtk.h: #include gtktextbufferrichtext.h
* gtk/gtktextbufferserialize.[ch]: new files implementing an
internal serialization format that can handle all of a text
buffer's tags and pixbufs. It's not useful for anything except
tranfer between instances of GtkTextBuffer (Anders Carlsson).
* gtk/Makefile.am: build the new files.
* gtk/gtkclipboard.[ch]: added convenience APIs for rich text,
just as they exist for plain text and pixbufs.
* gtk/gtkselection.[ch]: added rich text convenience APIs here
too. Return the target list from gtk_target_list_ref(). Register
GtkTargetList as boxed type. Added
gtk_target_table_new_from_list() and gtk_target_table_free(),
which make converting between GtkTargetList and arrays of
GtkTargetEntry considerably easier.
* gtk/gtktextutil.[ch]: added _gtk_text_util_create_rich_drag_icon()
which creates a fancy rich text icon (Matthias Clasen).
* gtk/gtktextbuffer.[ch]: use all the new stuff above and
implement copy and paste of rich text. Added APIs for getting the
target lists used for copy and paste. Added public enum
GtkTextBufferTargetInfo which contains the "info" IDs associated
with the entries of the target lists.
* gtk/gtktextview.c: use the new rich text APIs and
GtkTextBuffer's new target list API to enable DND of rich text
chunks.
* gtk/gtk.symbols: export all the new symbols added.
* tests/testtext.c: added rich text testing stuff.
