[rupert <rupertt gmail com>]

Hello,
im trying to create a dialog that show me the content of a textfile.
I already got it working in a standalone application, now im trying to
intregrate this into my main app.
The text is shown, but in a really small window, i also would like to know
if this is the right way i should
handle/do this. I dont wanna gedit or something.


  tags = gtk_text_tag_table_new();
  puffer = gtk_text_buffer_new(tags);
  ansicht2 = gtk_text_view_new_with_buffer(puffer);
  g_object_set(ansicht,"wrap-mode", GTK_WRAP_WORD, NULL);


     FILE *fp = fopen("/media/Data/readme.txt", "r");
    gchar text2[]="hallo";
    gchar line[512];

    if (fp)
    {
        while (fgets(line, sizeof(line), fp))
        {
        gtk_text_buffer_insert_at_cursor(puffer, line, -1);
        }
        fclose(fp);
    }


  rollen2 = g_object_new(GTK_TYPE_SCROLLED_WINDOW, NULL);
  gtk_container_add(GTK_CONTAINER(rollen2), GTK_WIDGET(ansicht2));

  hbuttonbox = gtk_hbutton_box_new ();
  gtk_widget_show (hbuttonbox);
  quit2 = gtk_button_new_with_mnemonic(("Quit"));
  gtk_box_pack_start(GTK_BOX(hbuttonbox), GTK_WIDGET(quit2), TRUE, TRUE,
10);
  g_signal_connect_swapped(quit2,"clicked",G_CALLBACK(ende), NULL);

  vbox2 = g_object_new(GTK_TYPE_VBOX, NULL);
  gtk_box_pack_start_defaults(GTK_BOX(vbox2), GTK_WIDGET(rollen2));
  gtk_box_pack_end(GTK_BOX(vbox2), GTK_WIDGET(hbuttonbox), FALSE, FALSE, 0);

  gtk_box_pack_start(GTK_BOX(dialog->vbox), GTK_WIDGET(vbox2), FALSE, FALSE,
0);
  gtk_container_add(GTK_CONTAINER(dialog), GTK_WIDGET(vbox));

g_signal_connect_swapped(manual,"clicked",G_CALLBACK(gtk_widget_show_all),dialog);
