Never unload print backends.
Remove gtk_print_backend_unref_at_idle.
* modules/printbackends/cups/gtkprintbackendcups.c:

Don't use the unref_at_idle hack since that caused
deadlocks. Instead we never unload print backends, which
is not really a big problem.

(gtk_notebook_tab_space), (gtk_notebook_calculate_shown_tabs),
(gtk_notebook_calculate_tabs_allocation): new functions,
gtk_notebook_pages_allocate() functionality has been splitted into

* gtk/gtk.symbols:
Added new symbols
* gtk/gtkpagesetupunixdialog.c:
* gtk/gtkprintunixdialog.c:
Destroy backends when finalizing dialogs.
Fix printer leak in selected_printer_changed.
* gtk/gtkprintbackend.[ch]:
Convert from interface to baseclass.
Move printer hashtable here so that the baseclass can handle
the slightly complicated ownership model.
Add gtk_print_backend_destroy which runs the dispose method,
causing the ref-cycles between the backend and its printers
to be broken.
Add gtk_print_backend_unref_at_idle().
* gtk/gtkprinter.[ch]:
GtkPrinter objects now ref their backend so that its always
availible, since its needed for the printer object to work.
This causes a reference-cycle that is broken using
gtk_print_backend_destroy.
Add gtk_printer_compare.

Convert backends to derive instead of implementing interface.
Move common code into baseclass.
CUPS:
Remove the printer polling in dispose, not finalize.
In the cups watch, remove the backend at idle instead of
immediately, since the unref can cause the module to be unloaded.
Limit the number of printer attributes requested
Get printer uri in initial printer listing so that we can use
the printer object immediately.
* tests/Makefile.am:
* tests/testnouiprint.c:
Add testcase for !show_dialog.

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.
2006-05-03 Matthias Clasen <mclasen@redhat.com>

* gtk/gtkpagesetupunixdialog.c: Beautify the custom
paper size dialog. (#339590, patch by Christian Persch)
2006-05-02 Kristian Rietveld <kris@imendio.com>
* gtk/gtktreeview.c (gtk_tree_view_row_inserted): set tmpnode to
the return value of the _gtk_rbtree_insert* functions, since that
is the node we really want to check for visibilty.

multiple times in the same function. Bug #340288.
2006-05-02 Michael Natterer <mitch@imendio.com>
* gtk/gtklabel.c (gtk_label_set_line_wrap): added note about the
inablity to do height-for-width text layout and suggest to use
gtk_widget_set_size_request() for getting a label that wraps at
some specific position.
2006-04-30 Kristian Rietveld <kris@imendio.com>
Fix for #340200, spotted by Torsten Schoenfeld.
* gtk/gtktreeview.c (gtk_tree_view_get_cell_area): fix up logic
calculating the level indentation,
(gtk_tree_view_start_editing): remove code calculating the
level indentation, since _get_cell_area() takes care of this for us.
2006-04-30 Matthias Clasen <mclasen@localhost.localdomain>
Fix problems with setting symbolic colors from rc files.
(#338345, Benjamin Berg)
* gtk/gtkrc.c (gtk_rc_settings_changed, gtk_rc_font_name_changed)
(gtk_rc_color_hash_changed, gtk_rc_reparse_all_for_settings): Don't
freeze notification for settings changes while parsing; instead
manually avoid recursion, and update the color hashes.
2006-04-30 Matthias Clasen <mclasen@localhost.localdomain>
* gtk/gtkprinteroption.c:
* gtk/gtkprinteroptionwidget.c:
* gtk/gtkprintunixdialog.c: Improve the print dialog layout,

position function for use with popups on status icons. (#334573,
Christian Persch)
2006-04-28 Matthias Clasen <mclasen@redhat.com>
* gtk/gtktreeview.c (gtk_tree_view_drag_begin): Don't force
the standard DND icon if the user has a custom DND source.
(#339522, Joe Wreschnig)
2006-04-28 Michael Natterer <mitch@imendio.com>
* gtk/gtktextbuffer.c (create_clipboard_contents_buffer): keep a
reference to the source buffer while the clipboard contents buffer
exists, because it is needed for serializing the contents buffer.
Makes copying from the contents buffer possible even after the
resp. text view is destroyed (for example when there is a
clipboard manager running on app exit) (bug #339195).
2006-04-27 Behdad Esfahbod <behdad@gnome.org>
* gdk/gdkpango.c (gdk_pango_renderer_draw_glyphs): Cast to double
before dividing by PANGO_SCALE. (#334582)

of the menu when popped up by keynav. (#334987, Christian
Persch)
2006-04-26 Federico Mena Quintero <federico@novell.com>
* gtk/gtkdialog.c (gtk_dialog_close): Don't make this conditional
on having a GTK_RESPONSE_CANCEL button -> end the idiocy. Fixes
bug #101293.
2006-04-26 Kristian Rietveld <kris@imendio.com>
* gtk/gtktreeview.c (node_is_visible): new function,
(validate_visible_area): when a node is validated, only queue a
redraw for that node, not for the entire widget (a redraw for the
entire widget is only needed when the sizes change, and
_queue_resize() will take care of that),
(do_validate_rows): do not queue a redraw, redraws are only needed
for changes in the visible area and validate_visible_area() takes
care of that,
(gtk_tree_view_row_inserted): for fixed height mode, only queue
a resize and redraw if the node is visible, else no redraw is needed.
2006-04-26 Kristian Rietveld <kris@imendio.com>
If this new "row-ending-details" property is turned on, more
detailed "details" will be passed to the theme engine for drawing
