(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.

(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.

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.

yeppers, accelerator changes to fix the gimp. commit message dedicated to yeppers, accelerator changes to fix the gimp. commit message dedicated to sopwith ;) Thu Jun 18 03:30:06 1998 Tim Janik <timj@gtk.org> * gtk/gtkaccellabel.h: * gtk/gtkaccellabel.c: new function gtk_accel_label_accelerator_width to request the size of the accelerator portion of an accel label. (gtk_accel_label_size_request): don't request for the accelerators size. (gtk_accel_label_expose_event): only draw the accelerator if we got enough extra space. * gtk/gtkmenuitem.c (gtk_menu_item_size_request): request accelerator width from children. * gtk/gtkmenu.c (gtk_menu_key_press): when adding an accelerator to an object (after removal has been requested) check if there is still an accelerator remaining to avoid adding two accelerators on an object. this can happen for locked accelerators (or accelerator-frozen widgets). (gtk_menu_size_request): feature childrens accelerator width in size requests. * gtk/gtknotebook.c (gtk_notebook_menu_item_create): use gtk_widget_freeze_accelerators() for dynamically created menu items. * gtk/gtksignal.h: * gtk/gtksignal.c: new function gtk_signal_handler_pending_by_func() which will return a handler_id > 0 if the specified function is pending for `signal_id'. * gtk/gtkwidget.h: * gtk/gtkwidget.c: remove gtk_widget_stop_accelerator, which was just a signal handler function to stop accelerator addition. added gtk_widget_freeze_accelerators and gtk_widget_thaw_accelerators which will prevent (undo) any accelerators from being added to or removed from a widget.
