- To terminal terminate the application when the GtkWindow is destroyed, connect "destroy" to gtk_main_quit callback using g_signal_connect()
- Add a GtkWidget of button to print "Hello GTK+\n" on screen by calling g_print().
Example code:
#include <gtk/gtk.h>
static void hello(GtkWidget *widget, gpointer data)
{
g_print("Hello GTK+\n");
}
int main(int argc, char *argv[])
{
GtkWidget *window;
GtkWidget *buttonHello;
gtk_init(&argc, &argv);
window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
buttonHello = gtk_button_new_with_label("Hello GTK+");
g_signal_connect(buttonHello, "clicked",
G_CALLBACK(hello), NULL);
//terminate the application when the GtkWindow is destroyed
g_signal_connect (window, "destroy",
G_CALLBACK(gtk_main_quit), NULL);
gtk_container_add(GTK_CONTAINER (window), buttonHello);
gtk_widget_show(buttonHello);
gtk_widget_show(window);
gtk_main();
return(0);
}
Compile and run the program as describe in last post.
