gtk 事件信号,和回调

#include<gtk/gtk.h>void hello(GtkWidget *widget,gpointer data){ g_print("Hello Ubuntu!/n");}gint delete_event(GtkWidget *widget,GdkEvent *event,gpointer data){ g_print ("delete event occurred/n"); gtk_main_quit(); return(TRUE);}void destroy(GtkWidget *widget,gpointer data){ gtk_main_quit();}int main( int argc, char *argv[] ){GtkWidget *hbox; GtkWidget *window; GtkWidget *button; GtkWidget *buttonclose; gtk_init (&argc, &argv); window=gtk_window_new (GTK_WINDOW_TOPLEVEL); gtk_signal_connect (GTK_OBJECT(window),"delete_event",GTK_SIGNAL_FUNC(delete_event),NULL); gtk_signal_connect (GTK_OBJECT (window), "destroy",GTK_SIGNAL_FUNC (destroy), NULL); gtk_container_set_border_width (GTK_CONTAINER (window), 10); button = gtk_button_new_with_label ("Hello Ubuntu!11111111111111111111111111111111111"); buttonclose=gtk_button_new_with_label("close"); gtk_signal_connect (GTK_OBJECT (button), "clicked",GTK_SIGNAL_FUNC (hello), NULL); gtk_signal_connect_object (GTK_OBJECT (buttonclose), "clicked",GTK_SIGNAL_FUNC (gtk_widget_destroy),GTK_OBJECT (window)); // gtk_container_add (GTK_CONTAINER (window), button); hbox=gtk_hbox_new (TRUE,5); gtk_box_pack_start(GTK_BOX(hbox),button,TRUE,FALSE,5); gtk_box_pack_start(GTK_BOX(hbox),buttonclose,TRUE,FALSE,5); gtk_container_add (GTK_CONTAINER(window),hbox); /* gtk_widget_show(buttonclose); gtk_widget_show (button); gtk_widget_show (hbox); gtk_widget_show (window); /*显示一个窗口*/ gtk_widget_show_all(window); gtk_main(); /*进入主循环*/ return(0);}
