* gtk/gtktextlayout.c (gtk_text_layout_move_iter_to_previous_line): (gtk_text_layout_move_iter_to_next_line): fix these two for invisible text, lots of other stuff still hosed. * gtk/gtkcolorsel.c (gtk_color_selection_set_change_palette_hook): new function, replaces the get/set palette stuff. This function is intended for use by libgnomeui which should set the hook to a thing which sets the palette in GConf, and we need the GConf-to-xsettings proxy which will result in the change being propagated back to the GTK app. * gtk/gtkaccelgroup.c (gtk_accel_group_add): add note to warning about unusable signals that it may be because the signal has parameters. * gtk/gtkwidget.c (gtk_widget_modify_style): always copy the style, otherwise gtkrc.c won't know to create a new GtkStyle for it. (gtk_widget_modify_color_component): call gtk_widget_modify_style() so the rc style will get copied. (gtk_widget_modify_font): ditto * gtk/gtkrc.c: make a couple variables static * gtk/gtkcolorseldialog.c (gtk_color_selection_dialog_init): hide help button by default, since it does nothing * gtk/gtkcolorsel.c: add tooltips, work on key navigation, fool around with UI * gtk/gtkentry.c (gtk_entry_realize): request enter/leave notify so we can have tooltips * gtk/gtkhsv.c (gtk_hsv_realize): request enter/leave notify so we can have tooltips * gdk/gdkimage.h: mark gdk_image_new_bitmap with GDK_ENABLE_BROKEN, because its memory behavior is completely hosed. * gtk/gtknotebook.c: remove key press handler, replace with binding set, add numeric keypad support * gtk/gtktextview.c (gtk_text_view_class_init): accept KP_Delete * gtk/gtktext.c (gtk_text_key_press): add a bunch of KP keysyms * gtk/gtkentry.c (gtk_entry_class_init): accept GDK_KP_Delete in addition to plain Delete * gtk/gtktextview.c (gtk_text_view_key_press_event): accept GDK_KP_Enter in addition to GDK_Return * gtk/gtkfontsel.c (gtk_font_selection_size_key_press): connect to activate on entry instead of key press (gtk_font_selection_on_clist_key_press): get rid of this signal handler, not needed with new font sel. * gtk/gtkfilesel.c (gtk_file_selection_key_press): remove a no-longer-needed emit_stop_by_name(), just return TRUE * gtk/gtkhscrollbar.c, gtk/gtkvscrollbar.c: remove keybindings cruft, this widget is no longer focusable. * gtk/gtkrange.h, gtk/gtkrange.c, gtk/gtkvscale.c, gtk/gtkhscale.c: Get rid of trough_keys virtual function, add move_slider action signal, add binding set for vscale/hscale, in the process support numeric keypad * gtk/gtkentry.c (gtk_entry_class_init): Add keypad bindings; make GDK_Return and GDK_KP_Enter activate the entry via binding set, instead of hardcoded.
