Adapt to GtkTreeSelection changes 2001-01-01 Havoc Pennington <hp@redhat.com> * gtk/gtktreeview.c: Adapt to GtkTreeSelection changes * gtk/gtktreeselection.c (_gtk_tree_selection_set_tree_view): don't fill in tree_view->priv->selection, kind of an unexpected side effect * gtk/gtkcellrenderertext.c: Remove definition of _ and include gtkintl.h * gtk/gtkcellrenderer.c: Remove definition of _ and include gtkintl.h (gtk_cell_renderer_get_property): remove calls to g_value_init * gtk/gtkcellrendererpixbuf.c: Remove definition of _ and include gtkintl.h * gtk/gtkcellrenderertextpixbuf.c: Remove definition of _ macro and include gtkintl.h (gtk_cell_renderer_text_pixbuf_class_init): remove spaces from property names * gtk/gtktreeselection.c (_gtk_tree_selection_new): rename, return GtkTreeSelection (_gtk_tree_selection_new_from_with_view): rename, return GtkTreeSelection (_gtk_tree_selection_set_tree_view): rename with uscore (gtk_tree_selection_get_selected): fill in the "model" out param first, so it gets filled in even if we return at the top of the function (gtk_tree_selection_real_select_all): add a comment and an else{} to clarify this a bit (gtk_tree_selection_real_unselect_all): add the same else{} * gtk/gtktreeselection.h: Rename new, new_with_tree_view, and set_tree_view to have underscore prefixes, move them to the private header, fix return type of new_with_tree_view (struct _GtkTreeSelection): mark struct fields private * gtk/gtktreemodel.c (gtk_tree_model_get_flags): return GtkTreeModelFlags, not a guint (gtk_tree_path_prev): return gboolean not gint (gtk_tree_path_up): return gboolean not gint * gtk/gtktreemodel.h (struct _GtkTreeModelIface): make get_flags return GtkTreeModelFlags, not a guint * gtk/gtktreemodelsort.c (gtk_tree_model_sort_finalize): check that child model is non-null before unrefing it (g_value_int_compare_func): make this a qsort compare func, not a boolean predicate * gtk/gtktreemodelsort.h: rename gtk_tree_model_set_sort_column, (add -umn to the end), and mark it unimplemented (gtk_tree_model_sort_resort): remove, this wasn't implemented, and I don't see what it's for - doesn't the model always sort itself? (gtk_tree_model_sort_set_compare): this had the wrong signature * gtk/gtktreeviewcolumn.c (gtk_tree_view_column_set_attributes): Fix the docs to say that it destructively replaces existing attributes (previously said that it added attributes). (gtk_tree_view_column_set_visible): canonicalize bool before equality testing. Also, check for realization before hiding/showing the tree_column->window; if this window could exist before realization, then it's busted and needs fixing, we can't create GDK resources pre-realization. Also, remove superfluous queue_resize(), since set_size() does that for us. (gtk_tree_view_column_set_col_type): check realization before using tree_column->window * gtk/gtktreedatalist.c: fix filename in copyright notice

urg, removed implementation of gtk_marshal_VOID__INT_INT_INT_INT. if Wed Oct 25 20:47:41 2000 Tim Janik <timj@gtk.org> * gtk/gdk-pixbuf-loader.c (gdk_pixbuf_loader_class_init): urg, removed implementation of gtk_marshal_VOID__INT_INT_INT_INT. if people do that, couldn't they at least give it a non-standard name? * gtk/gtktextlayout.c: arg! yet another implementation of gtk_marshal_VOID__INT_INT_INT_INT(), is this a conspiracy? * gtk/gtktextbuffer.c: gotcha! captured a vagabonding gtk_marshal_VOID__INT_POINTER_INT() implementation, braught it back home. now i know this _is_ a conspiracy. * gtk/gtkwidget.c (gtk_widget_class_init): marshaller fixups for ::state-changed. * gtk/gtkaccelgroup.c (gtk_accel_group_create_remove): (gtk_accel_group_create_add): marshaller signature fixups. * gtk/gtklistitem.c (gtk_list_item_class_init): signal creation fixups, pass in GTK_TYPE_SCROLL_TYPE instead of GTK_TYPE_ENUM. * gtk/gtkobject.[hc]: removed GTK_CONNECTED flag, it's not valid anymore. Tue Oct 24 23:59:21 2000 Tim Janik <timj@gtk.org> * docs/reference/Makefile.am: disabled SUBDIRS for the moment, since due to the signal system changes, it wouldn't build currently. to be fixed soon. * docs/Changes-2.0.txt: GtkSignal/GSignal updates. * gtk/gtkwidget.c: ::direction_changed takes an enum as argument, so it needs gtk_marshal_VOID__ENUM() instead of gtk_marshal_NONE__UINT(). * gdk/gdk*.c: adapted type registration functions. * gtk/gtkbindings.c: * gtk/gtkaccelgroup.c: operate on GSignalQuery, GtkSignalQuery is gone. * gtk/gtkenums.h: define GtkSignalRunType in terms of GSignalType. * gtk/gtkobject.c: (gtk_object_destroy): (gtk_object_shutdown): fixed recursion guards. basically we have to catch the case where any of GObject.shutdown() or gtk_object_destroy() is called during ::destroy, and avoid recursion there. * gtk/gtktypeutils.c: * gtk/maketypes.awk: awk-script hackup to provide gtk_type_init() with boxed_copy/boxed_free. this needs a more general solution based on a publically installed code-generator utility. * gtk/gtktypeutils.[hc]: compat aliased GTK_TYPE_BOXED to G_TYPE_BOXED, glib's gobject has support for that now. define GtkSignalMarshaller in terms of GSignalCMarshaller. Mon Oct 23 09:36:42 2000 Tim Janik <timj@gtk.org> * gtk/gtksignal.[hc]: * gtk/gtkmarshal.[hc]: * gtk/Makefile.am: generate marshallers with glib-genmarshal and don't compile gtkmarshal.c on its own anymore, just include it in gtksignal.c. removed #include <gtkmarshal.h>s all over the place, gtksignal.h takes care of that. * *.c: marshaller name fixups. * gtk/gtkmarshal.list: added a comment briefing the format. Sun Oct 22 23:14:39 2000 Tim Janik <timj@gtk.org> * gtk/gtksignal.[hc]: nuked old implementation. we mostly have compatibility macros here now. more specifically, most of the API is preserved (yes, _most_, nonwithstanding the following exceptions listed, the API is stil lHUGE ;) things that got removed completely: GtkSignalQuery, gtk_signal_query(), gtk_signal_n_emissions(), gtk_signal_n_emissions_by_name(), gtk_signal_handlers_destroy(), gtk_signal_set_funcs(), gtk_signal_handler_pending_by_id(), gtk_signal_add_emission_hook(), gtk_signal_add_emission_hook_full(), gtk_signal_remove_emission_hook(). non-functional functions variants: gtk_signal_add_emission_hook(), gtk_signal_remove_emission_hook(). the GtkCallbackMarshal argument to gtk_signal_connect_full() is not supported anymore. (gtk_signal_compat_matched): new internal function to aid implementation of the compatibility macros, it provides functionality to block/unblock/disconnect handlers based on func/data. * gtk/gtkenums.h: define GtkSignalRunType in terms of GSignalType, * *.c: adaptions to new type registration API signatures. Fri Oct 20 15:26:33 2000 Tim Janik <timj@gtk.org> * gtk/gtktypeutils.[hc]: removed G_TYPE_GTK_POINTER cludge.
