added args ::show_text, ::text_xalign, ::text_yalign, ::activity_mode. Sun Nov 22 16:21:28 1998 Tim Janik <timj@gtk.org> * gtk/gtkprogress.c: added args ::show_text, ::text_xalign, ::text_yalign, ::activity_mode. * gtk/gtkprogressbar.c: added construct arg ::adjustment. added args ::bar_style, ::orientation, ::discrete_blocks, ::activity_step, ::activity_blocks. (gtk_progress_bar_new): (gtk_progress_bar_new_with_adjustment): use gtk_widget_new(). (gtk_progress_bar_construct): deprecated. * gtk/gtkvscrollbar.c: (gtk_vscrollbar_draw_step_back): (gtk_vscrollbar_draw_step_forw): use "vscrollbar" as detail for gtk_paint_arrow, to be consistent with hscrollbar. * gtk/gtktext.c added construct args ::hadjustment, ::vadjustment. added args ::line_wrap, ::word_wrap. (gtk_text_class_init): added scroll_adjustments signal. (gtk_text_new): use gtk_widget_new. (gtk_text_disconnect): remove adjustement with gtk_text_set_adjustments, so we don't screw the reference counts and don't leave signals connected. (gtk_text_destroy): disconnect adjustments signals. (gtk_text_finalize): unref adjustments. * gtk/gtkctree.c: added construct args ::n_columns and ::tree_column. added args ::indent, ::spacing, ::show_stub, ::reorderable, ::use_drag_icons, ::line_style and ::expander_style. (gtk_ctree_set_show_stub): renamed from gtk_ctree_show_stub, which is deprecated now. * gtk/gtkclist.h: remove GTK_CLIST_CONSTRUCT flag. * gtk/gtkclist.c: removed ::vadjustment and ::hadjustment args, introduced ::scroll_adjustments signal. added ::shadow_type, ::selection_mode and ::row_height args. added n_columns construct arg. (gtk_clist_construct): call gtk_object_constructed(). (gtk_clist_set_row_height): if height is passed as 0, revert to automatic height calculation. (gtk_clist_destroy): before unrefing the adjustments, disconnect our signal handlers. Fri Nov 21 22:34:58 1998 Tim Janik <timj@gtk.org> * gtk/gtkwidget.c (gtk_widget_new): call gtk_object_default_construct like gtk_object_new. (gtk_widget_destroy): assert that we only destroy constructed widgets. * gtk/gtkobject.h (enum GtkArgFlags): new flag GTK_ARG_CONSTRUCT_ONLY to identify args that may only be used for construction. GTK_ARG_CONSTRUCT maybe used as normal arguments besides construction time. * gtk/gtkobject.c (gtk_object_new): invoke gtk_object_default_construct at the end if the object is not fully constructed. (gtk_object_newv): likewise. (gtk_object_destroy): assert that we only destroy constructed objects. (gtk_object_init): setup GTK_CONSTRUCTED from the objects real klass. (gtk_object_default_construct): new function to complete default construction of an object by applying missing construtor args with default values of 0, 0.0 or NULL. (gtk_object_constructed): new function to mark an object as being constructed (used from within constructors). * gtk/gtkarg.c (gtk_arg_type_new_static): return the args info pointer so it is immediatedly available for the caller. * gtk/gtktypeutils.c (gtk_type_new): pass an object's real class to the object initilizer (GtkObjectInitFunc takes a second arg now, the real klass), and asure that object initializers may temporarily alter the class pointer. Fri Nov 20 08:00:30 1998 Tim Janik <timj@gtk.org> * gtk/testgtk.c: change all occourances of gtk_container_add ( scrolled_window, widget) to gtk_scrolled_window_add_with_viewport (...) for widget!=(clist, ctree, text, viewport). * gtk/gtkcombo.c: (gtk_combo_init): use gtk_scrolled_window_add_with_viewport() to add children to the scrolled window. * gtk/gtkscrolledwindow.h: * gtk/gtkscrolledwindow.c: changed scrolled_window->viewport to scrolled_window->child, and use gtk_widget_scroll_adjustements() to set the scroll adjustments for the widget, we do not create an additional viewport anymore. added ::hadjustment and ::vadjustment constructor args. (gtk_scrolled_window_new): use gtk_widget_new() to create the widget. (gtk_scrolled_window_set_hadjustment): (gtk_scrolled_window_set_vadjustment): new functions that superceed gtk_scrolled_window_construct. (gtk_scrolled_window_construct): deprecated this function. * gtk/gtkhscrollbar.c: * gtk/gtkvscrollbar.c: * gtk/gtkhscale.c: * gtk/gtkvscale.c: support a constructor arg "::adjustment", and use gtk_widget_new() for the widget creation. * gtk/gtkrange.c: added ::update_policy arg. (gtk_range_set_adjustment): if adjustment is passed in as NULL, create a default adjustment so this function can be used for derived widgets that depend on the adjustment's existance. (gtk_range_destroy): disconnect the adjustment signal, so we don't get called after we got destroyed, we don't destroy the adjustment in here, because it might have been provided from another widget. * gtk/gtkviewport.c: introduced ::scroll_adjustments signal. (gtk_viewport_destroy): same as gtk_range_destroy. * gtk/gtkprogress.c (gtk_progress_destroy): same as gtk_range_destroy. * gtk/gtkwidget.h: * gtk/gtkwidget.c: changed gtk_widget_activate() to return a gboolean, indicating whether this widget supports activation. added gtk_widget_scroll_adjustements() to set the scrolling adjustments of a widget. Wed Nov 19 01:22:42 1998 Tim Janik <timj@gtk.org> * gtk/gtkoptionmenu.c: (gtk_option_menu_remove_contents): (gtk_option_menu_update_contents): removed gtk_container_[un]block_resize() pairs. * gtk/gtknotebook.h: * gtk/gtknotebook.c: removed the tab_border field, since it shouldn't be used outside of gtknotebook.c anyways. made ARG_TAB_BORDER a wrtie-only argument. * *.c: made deprecated functions issue a message: gtk_clist_set_border, gtk_container_block_resize, gtk_container_unblock_resize, gtk_container_need_resize, gtk_object_class_add_user_signal, gtk_spin_button_construct, gtk_scrolled_window_construct. removed non-functional functions: gtk_container_disable_resize, gtk_container_enable_resize, gtk_clist_set_policy. Wed Nov 18 22:54:36 1998 Tim Janik <timj@gtk.org> * gtk/gtkbox.c (gtk_box_init): * gtk/gtkdrawingarea.c (gtk_drawing_area_init): * gtk/gtkeventbox.c (gtk_event_box_init): * gtk/gtkfixed.c (gtk_fixed_init): * gtk/gtkframe.c (gtk_frame_init): * gtk/gtkhandlebox.c (gtk_handle_box_init): * gtk/gtkpacker.c (gtk_packer_init): * gtk/gtkmisc.c (gtk_misc_init): * gtk/gtkpreview.c (gtk_preview_init): * gtk/gtkprogress.c (gtk_progress_init): * gtk/gtkprogressbar.c (gtk_progress_bar_init): * gtk/gtkseparator.c (gtk_separator_init): * gtk/gtktable.c (gtk_table_init): * gtk/gtkviewport.c (gtk_viewport_init): * gtk/gtkalignment.c (gtk_alignment_init): removed setting of the GTK_BASIC flag. * gtk/gtkwidget.h: * gtk/gtkwidget.c: removed GTK_BASIC, GTK_WIDGET_BASIC and gtk_widget_basic. * miscellaneous GtkType and macro fixups.

fix some shell typos 2001-05-04 Havoc Pennington <hp@redhat.com> * configure.in: fix some shell typos * gtk/gtkcolorsel.c (gtk_color_selection_destroy): warning fix * gtk/gtkimage.c: handle animations * gtk/gtkcheckbutton.c (gtk_check_button_size_request): request border_width * 2, not just border_width * gtk/gtkscale.c: add "format_value" signal to allow people to override the way values are drawn. (gtk_scale_get_value_size): fix width/height mistake, and compute size from actual displayed text, not from made-up text. * gtk/gtktexttag.c (gtk_text_tag_class_init): fix return type in signal registration * tests/testtext.c: Add "Remove all tags" menu item for testing * gtk/gtktextbuffer.c (gtk_text_buffer_remove_all_tags): implement * demos/gtk-demo/main.c (main): add hack so we can find modules without installing gtk * demos/gtk-demo/textview.c (insert_text): demo font scaling * gtk/gtkcellrenderertext.c: Add "scale" property (font scaling factor) (gtk_cell_renderer_text_set_property): remove some bogus g_object_notify * gtk/gtktexttag.c: add "scale" property which is a font scaling factor * gtk/gtktextlayout.c (add_text_attrs): add font scale attribute to layout * gtk/gtktextiter.c (gtk_text_iter_is_start): rename from gtk_text_iter_is_first 2001-05-04 Havoc Pennington <hp@redhat.com> * pixops/pixops.c (pixops_process): merge fix from stable: Patch from hoshem@mel.comcen.com.au to fix nonzero X offsets. Fixes bug #50371. * gdk-pixbuf/pixops/pixops.c (pixops_composite_nearest): merge from stable: Patch from OKADA Mitsuru <m-okada@fjb.co.jp> to fix confusion of using "src" instead of "p". (pixops_composite_color_nearest): Use a more accurate (and correct, to begin with) compositing method. This cures checks showing through on images with no alpha. * gdk-pixbuf.c (gdk_pixbuf_fill): fix bug that left some trailing bytes unfilled. * gdk-pixbuf-io.h: fix UpdatedNotifyFunc to use signed ints * gdk-pixbuf-loader.h (struct _GdkPixbufLoaderClass): Change area_updated signal to use signed ints. Removed animation-related signals. * io-gif.c, io-gif-animation.h, io-gif-animation.c: Massive rewrite action * gdk-pixbuf-animation.c: Add GdkPixbufAnimationIter to abstract all the pesky details. Remove old frame-based API. Make GdkPixbufAnimation an abstract base class, derived by the loaders.
