gtk container에 label 위젯 추가

새로운 widget을 기존 window에 추가하려면 GtkContainer를 이용하면 됨

  #include <gtk/gtk.h> void destroy(GtkWidget *window, gpointer data) { printf("destroy function is called\n"); gtk_main_quit(); } gboolean delete_event_handler(GtkWidget *window, GdkEvent *event, gpointer data) { printf("delete event handler is called\n"); return FALSE; /* return FALSE --> destroy */ } int main(int argc, char *argv[]) { GtkWidget *window = NULL; GtkWidget *label = NULL; gtk_init(&argc, &argv); window = gtk_window_new(GTK_WINDOW_TOPLEVEL); gtk_window_set_title(GTK_WINDOW(window), "Hello World"); gtk_container_set_border_width(GTK_CONTAINER (window), 10); gtk_widget_set_size_request(window, 200, 100); g_signal_connect(G_OBJECT(window), "destroy", G_CALLBACK(destroy), NULL); g_signal_connect(G_OBJECT(window), "delete_event", G_CALLBACK(delete_event_handler), NULL); /* LABEL 위젯 추가 */ label = gtk_label_new("This is label widget"); gtk_label_set_selectable(GTK_LABEL(label), TRUE); /* window의 container에 label 위젯을 연결 */ gtk_container_add(GTK_CONTAINER (window), label); gtk_widget_show_all(window); gtk_main(); return 0; }
