ubuntu 에서 gtk 설치 & sample code

- gtk 2 설치

apt-get install libgtk2.0-dev 를 실행시킨 후 Y를 입력한다.

(root 로그인이 아닌 경우는 sudo apt-get install libgtk2.0-dev )

 

- gtk 3 설치

#apt-get install libgtk-3-dev

 

 

- BackTrack5 R2 KDE 환경에서 설치함.

 

- 설치가 잘 되었는지 sample code를 만들어 보자. (http://www.levien.com/gimp/hello.html)

아래 코드를 hello.c 로 저장한다.

 

#include <gtk/gtk.h>

void
hello (void)
{
  g_print ("Hello World\n");
}

void
destroy (void)
{
  gtk_main_quit ();
}

int
main (int argc, char *argv[])
{
  GtkWidget *window;
  GtkWidget *button;

  gtk_init (&argc, &argv);

  window = gtk_window_new (GTK_WINDOW_TOPLEVEL);
  gtk_signal_connect (GTK_OBJECT (window), "destroy",
      GTK_SIGNAL_FUNC (destroy), NULL);
  gtk_container_border_width (GTK_CONTAINER (window), 10);

  button = gtk_button_new_with_label ("Hello World");

  gtk_signal_connect (GTK_OBJECT (button), "clicked",
      GTK_SIGNAL_FUNC (hello), NULL);
  gtk_signal_connect_object (GTK_OBJECT (button), "clicked",
     GTK_SIGNAL_FUNC (gtk_widget_destroy),
     GTK_OBJECT (window));
  gtk_container_add (GTK_CONTAINER (window), button);
  gtk_widget_show (button);

  gtk_widget_show (window);

  gtk_main ();

  return 0;
}

 

- compile

# gcc hello.c -o hello `pkg-config --cflags --libs gtk+-2.0`

 

- execution

./hello

 

 

 

 

- 위의 소스 코드를 gtk+-3.0 으로 컴파일 하면 아래와 같이 에러가 발생한다.

 

# gcc hello.c -o hello `pkg-config --cflags --libs gtk+-3.0`

- gcc hello.c -o hello `pkg-config --cflags --libs gtk+-3.0` 로 빌드하기 위해서는 아래 코드를 사용하자.

 

#include <gtk/gtk.h> 

void hello(GtkWidget *widget,gpointer data) 

{ 

    g_print("Hello GClinux!\n"); 

}

 

gint delete_event(GtkWidget *widget,GdkEvent *event,gpointer data) 

{ 

    g_print ("delete event occurred\n"); 

    return(TRUE); 

}

 

void destroy(GtkWidget *widget,gpointer data) 

{ 

    gtk_main_quit(); 

} 

 

int main( int argc, char *argv[] ) 

{ 

    GtkWidget *window; 

    GtkWidget *button; 

    gtk_init (&argc, &argv); 

    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); 

    gtk_container_set_border_width (GTK_CONTAINER(window), 10); 

    button = gtk_button_new_with_label ("hello"); 

    g_signal_connect (G_OBJECT(button), "clicked",G_CALLBACK(hello), NULL); 

    g_signal_connect_swapped(G_OBJECT(button), "clicked",G_CALLBACK(gtk_widget_destroy),G_OBJECT(window)); 

    gtk_container_add (GTK_CONTAINER(window), button); 

    gtk_widget_show (button); 

    gtk_widget_show (window);    

    gtk_main();    

    return(0); 

}
