fixed an assertment. Sat Jun 6 06:01:24 1998 Tim Janik <timj@gtk.org> * gtk/gtksignal.c (gtk_signal_emitv): fixed an assertment. * gtk/makeenums.awk: a script to generate the GtkEnumValue arrays from, this should eventually be done by gentypeinfo.el somewhen. * gtk/gtkenumvalues.c: new generated file to hold GtkEnumValue arrays. * gtk/gtktypeutils.h: new function gtk_enum_values() to retrive all the enum values of an enum type. * gtk/gtk.defs: * gtk/gtkcurve.h: * gtk/gtkobject.h: * gtk/gtkprivate.h: * gtk/gtkwidget.h: * gtk/gtkenums.h: brought enum/flags definitions in sync, added a few more enum definitions for bindings and pattern matching. * some more macro and GtkType fixups in various places. * gdk/gdktypes.h (enum): added a new value GDK_AFTER_MASK, which is used as a key-release modifier for the binding system. Fri Jun 5 06:06:06 1998 Tim Janik <timj@gtk.org> * gtk/gtkmenu.h (struct _GtkMenu): removed GList*children, since it was a stale list pointer that is already present in GtkMenuShell. * gtk/gtkmenushell.h (struct _GtkMenuShellClass): added a signal GtkMenuShell::selection_done which is emitted after the menu shell poped down again and all possible menu items have been activated. Thu Jun 4 02:20:42 1998 Tim Janik <timj@gtk.org> * gtk/gtkmenushell.c (gtk_menu_shell_button_release): flush the x-queue before activation of the menuitem, so the menu is actually taken off the screen prior to any menu item activation. * gtk/gtkctree.c (gtk_ctree_get_row_data): allow function invokation for NULL nodes. * gtk/gtkwidget.h: * gtk/gtkwidget.c: new function gtk_widget_stop_accelerator to stop the emission of the "add-accelerator" signal on a widget. this is usefull to prevent accelerator installation on certain widgets. * gtk/gtknotebook.c (gtk_notebook_menu_item_create): keep the menu labels left justified, by setting their alignment. stop accelerator installation for the menu items, since we use dynamic menus. Wed Jun 3 06:41:22 1998 Tim Janik <timj@gtk.org> * gtk/gtkmenufactory.c: adaptions to use the new accel groups. people should *really* use GtkItemFactory. this is only for preserving source compatibility where possible, use of GtkMenuFactory is deprecated as of now. * gtk/gtkobject.h (gtk_object_class_add_user_signal): new function to create user signals of type GTK_RUN_NO_RECURSE. don't know why i missed this possibility when i added gtk_object_class_add_user_signal in late january. * gtk/gtkmain.c (gtk_init): ignore subsequent function calls. Sun May 31 07:31:09 1998 Tim Janik <timj@gtk.org> * gtk/gtkaccelgroup.h: * gtk/gtkaccelgroup.c: new implementation of the accelerator concept. * gtk/gtkaccellabel.h: * gtk/gtkaccellabel.c: new widget derived from GtkLabel whitch features display of the accelerators associated with a certain widget. * gtk/gtkitemfactory.h: * gtk/gtkitemfactory.c: new widget, item factory with automatic rc parsing and accelerator handling. * gtk/gtkmenu.c (gtk_menu_reposition): new function to care for positioning a menu. (gtk_menu_map): removed the allocation code. (gtk_menu_size_allocate): care for redrawing of children and resize our widget->window correctly. (gtk_menu_key_press): feature the new accelerator groups. * gtk/gtkmenuitem.c (gtk_menu_item_size_allocate): reposition the submenu if neccessary. * gtk/gtkmenuitem.c: * gtk/gtkcheckmenuitem.c: * gtk/gtkradiomenuitem.c: use GtkAccelLabel in the *_new_with_label() function variants. * gdk/gdk.c: (gdk_keyval_from_name): (gdk_keyval_name): new functions for keyval<->key-name associations. (gdk_keyval_to_upper): (gdk_keyval_to_lower): (gdk_keyval_is_upper): (gdk_keyval_is_lower): new functions to check/translate keyvalues with regards to their cases. Wed May 27 00:48:10 1998 Tim Janik <timj@gtk.org> * gtk/gtkwidget.c (gtk_widget_class_path): new function to calculate a widget's class path. (gtk_widget_path): new function to calculate a widget's name path. * gtk/gtkrc.c: newly introduced GtkPatternSpec structures to speed up pattern matching, features reversed pattern matches.
