Therefore it is not prepared to deal with 2314 * operations that produce different results depending on the 2315 * locale, such as printf's formatting of decimal numbers, and 2316 * possibly others. 2317 * 2318 * Since GTK+ calls setlocale() by default -importing the locale 2319 * settings from the environment- we must prevent it from doing so 2320 * using gtk_disable_setlocale(). 2321 * 2322 * QEMU's GTK+ UI, however, _does_ have translations for some of 2323 * the menu items. As a trade-off between a functionally correct 2324 * QEMU and a fully internationalized UI we support importing 2325 * LC_MESSAGES from the environment (see the setlocale() call 2326 * earlier in this file). This allows us to display translated 2327 * messages leaving everything else untouched. 2328 */ 2329 gtk_disable_setlocale(); 2330 gtkinit = gtk_init_check(NULL, NULL); 2331 if (!gtkinit) { 2332 /* don't exit yet, that'll break -help */ 2333 return; 2334 } 2335 2336 switch (opengl) { 2337 case -1: /* default */ 2338 case 0: /* off */ 2339 break; 2340 case 1: /* on */ 2341 #if defined(CONFIG_OPENGL) 2342 #if defined(CONFIG_GTK_GL) 2343 gtk_gl_area_init(); 2344 #else 2345 gtk_egl_init(); 2346 #endif 2347 #endif 2348 break; 2349 default: 2350 g_assert_not_reached(); 2351 break; 2352 } 2353 2354 #if defined(CONFIG_VTE) 2355 type_register(&char_gd_vc_type_info); 2356 register_char_driver(&gd_vc_driver); 2357 #endif 2358 } 2359
