I have been trying to implement Win32's MessageBox using GTK. The app using SDL/OpenGL, so this isn't a GTK app. I handle the initialisation (gtk_init) sort of stuff inside the MessageBox function as follows:int MessageBox(HWND hwnd, const char* text, const char* caption, UINT type){GtkWidget *window = NULL;GtkWidget *dialog = NULL;gtk_init(&gtkArgc, &gtkArgv);window = gtk_window_new(GTK_WINDOW_TOPLEVEL);g_signal_connect(G_OBJECT(window), "delete_event", G_CALLBACK(delete_event), NULL);g_signal_connect(G_OBJECT(window), "destroy", G_CALLBACK(destroy), NULL);// gcallback calls gtk_main_quit()gtk_init_add((GtkFunction)gcallback, NULL);if (type & MB_YESNO) {dialog = gtk_message_dialog_new(GTK_WINDOW(window), GTK_DIALOG_DESTROY_WITH_PARENT, GTK_MESSAGE_QUESTION, GTK_BUTTONS_YES_NO, text);} else {dialog = gtk_message_dialog_new(GTK_WINDOW(window), GTK_DIALOG_DESTROY_WITH_PARENT, GTK_MESSAGE_INFO, GTK_BUTTONS_OK, text);}gtk_window_set_title(GTK_WINDOW(dialog), caption);gint result = gtk_dialog_run(GTK_DIALOG(dialog));gtk_main();gtk_widget_destroy(dialog);if (type & MB_YESNO) {switch (result) {default:case GTK_RESPONSE_DELETE_EVENT:case GTK_RESPONSE_NO:return IDNO;break;case GTK_RESPONSE_YES:return IDYES;break;}}return IDOK;} Now, I am by no means an experienced GTK programmer, and I realise that I'm probably doing something horribly wrong.However, my problem is that the last dialog popped up with this function stays around until the process exits. Any ideas?
