Ok, this time I fixed the problem, which appeared with any change which resulted in summary frame pixel size change of zero along both coordinates. I also made menubar obey to the same mechanism. Kirill 1998-05-06 Kirill M. Katsnelson <kkm(a)kis.ru&gt; * frame.h (struct frame): Added char_{width,height} member variables and access macros Added size_slipped redisplay bit and mark/clear macros. * redisplay.c (redisplay_frame): Adjust frame size if size slipped bit is set. (redisplay_device): Call redisplay_frame if size slipped bit is set. * frame.c (adjust_frame_size): Redisplay beats frame back in shape with this. Added. (frame_size_slipped): Added. (internal_set_frame_size): Clear size slipped bit. (change_frame_size_1): Store real charsize into frame object. (vars_of_frame): Declared adjust-frame-function. * frame-msw.c (mswindows_update_frame_external_traits): Same change as for frame-x.c (mswindows_frame_size_fixed_p): Implemented the method. * frame-x.c (x_update_frame_external_traits): Do not call Fset_frame_size to adjust frame, redisplay will do. * faces.c (update_EmacsFrame): Mark frame as slipped when default font changes. * toolbar.c (compute_frame_toolbars_data): Removed obsoleted call to change_frame_size. Redisplay will fix it later. Removed toolbar_*_changed_in_frame specifier change handlers. (specifier_vars_of_toolbar): Calls to these routed to frame_size_slipped generic handler. * toolbar-x.c: Removed toolbar_*_changed_in_frame device methods. * scrollbar-x.c: Removed scrollbar_*_changed_in_frame device methods. * scrollbar.c: Removed scrollbar_*_changed_in_frame specifier change handlers. (specifier_vars_of_scrollbar): Calls to the above changed to frame_size_slipped generic handler. * menubar-x.c (x_update_frame_menubar_internal): Do not resize frame, just mark frame size as slipped. * device-x.c: Removed declaration of in_specifier_change_function. * EmacsFrame.c (EmacsFrameSetValues): Do not check in_specifier_change_function. (EmacsFrameSetValues): Simulate a call to resize callback when no actual geometry change happened. * console.h (struct console_methods): Removed declarations for all <specifier>_changed_in_frame methods for toolbars and scrollbars. Added frame_size_fixed_p method.
