Sun Apr 1 22:22:47 2001 Owen Taylor <otaylor@redhat.com> [ Addition of safety checks to try to avoid segfaulting on broken setups always. ] * gdk/gdkfont.c (_gdk_font_wc_to_glyphs): Add a boolean return value to deal with failure of conversion of wide characters to glyphs. * gtk/gtkentry.c gtk/gtklabel.c: Handle failure of mbstowcs/wcstombs a bit better. * gdk/gdkfont.c gdk/gdkdraw.c: Deal with failure of _gdk_font_wc_to_glyphs() gracefully * gdk/gdkim.c (_gdk_wcstombs_len): quietly return NULL on failure instead of g_return_if_fail(). Wed Mar 28 16:05:29 2001 Owen Taylor <otaylor@redhat.com> * gtk/gtkfontsel.c (gtk_font_selection_select_size): Fix problem where fractional sizes caused infinite loop.
