body: <p>How to create gtk+ windows without title bar with resize and move properties working.
  I checked <code>gtk_window_set_decorated</code> function, but it disable resize and move features of window. I found <a href="https://stackoverflow.com/questions/1516092/how-to-create-gtk-windows-without-title-bar/1516104#1516104?newreg=db72f9175f9a4f53bbfbe945803c23cc">this answer already</a>, but I don't think it has anything to do with it. </p>
  
  <p>I tried to set resizeable true after gtk_window_set_decorated but still not working</p>
  
  <p>Please check code</p>
  
  <pre><code>    #include &lt;gtk/gtk.h&gt;
      int main (int argc,
      char *argv[])
      {  
        GtkWidget *window;
        /* Initialize GTK+ and all of its supporting libraries. */
        gtk_init (&amp;argc, &amp;argv);
        /* Create a new window, give it a title and display it to the user. */
        window = gtk_window_new (GTK_WINDOW_TOPLEVEL);
        gtk_window_set_title (GTK_WINDOW (window), "Hello World");
        gtk_window_set_decorated (GTK_WINDOW (window), FALSE);
        gtk_window_set_resizable (GTK_WINDOW (window), TRUE);
        //gtk_window_set_gravity(GTK_WINDOW (window), GDK_GRAVITY_NORTH_EAST);
        //gtk_window_set_deletable (GTK_WINDOW (window), FALSE);
        gtk_widget_show (window);
        /* Hand control over to the main loop. */
        gtk_main ();
        return 0;
      }
  </code></pre>
