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.

configure.in acheader.h gdk/gdkwindow.c Check for Shape extension both on Sun May 3 13:38:22 1998 Owen Taylor <otaylor@gtk.org> * configure.in acheader.h gdk/gdkwindow.c Check for Shape extension both on the client and server side. (And, more importantly, check for the shape extension so we may include -lXext even when compiling with --disable-xshm) Don't set override_redirect on all shaped windows. It isn't necessary. * gdk/gdkwindow.c: Set ->colormap to NULL for root and foreign windows. Use this to check if we need to get the colormap from X. Fri May 1 22:32:47 1998 Owen Taylor <otaylor@gtk.org> * gtk/gtkbutton.c (gtk_button_paint): Draw the areas between the default and the button always in GTK_STATE_NORMAL. * gtk/gtkrange.c (gtk_range_style_set): Added a style_set callback. Fri May 1 16:40:57 1998 Owen Taylor <otaylor@gtk.org> * gdk/gdkpixmap.c (gdk_pixmap_colormap_create_from_xpmp[_d]): Fix a buffer overflow on pixmaps that claim to have more than 31 characters per pixel. (gdk_pixmap_read_string): Don't wrap around strings longer than half of address space ;-) * gtk/gtk[vh]ruler.c gtk/gtkinputdialog.c: Expand some buffers that were used for printing integers. * */* (almost): Style: All int foo () { ... } changed to int foo (void) { ... } ^^^^^^^ This is why some many files changed Even where there were proper prototypes elsewhere. * gdk/gxid.c (handle_claim_device): Some extra checks. It isn't safe against being fed bad X id's, but at least it should be safe against deleting all your files.
