You can try this:

  if (gtk_dialog_run (GTK_DIALOG (dlg)) == GTK_RESPONSE_ACCEPT) {
    /* gets file path and name as a (gchar *)
     */
    gFile_in = gtk_file_chooser_get_filename (GTK_FILE_CHOOSER (dlg));
    /* opens a GIOChannel for input
     */
    input    = g_io_channel_new_file (gFile_in, "r", NULL);
    /* gets file content in a buffer of type (gchar *)
     */
    g_io_channel_read_to_end (input, & buffer, NULL, NULL);
    /* closes the GIOChannel
     */
    g_io_channel_shutdown (input, FALSE, NULL);
    g_io_channel_unref (input);

    /* gets a pointer to the text buffer associated
     * with an existing textview
     */
    text_buf  = gtk_text_view_get_buffer (GTK_TEXT_VIEW (text_view));
    /* puts the buffer into the text buffer
     */
    gtk_text_buffer_set_text (text_buf, buffer, -1);

    /* deallocates memory
     */
    g_free (buffer);
  }
  gtk_widget_destroy (dlg);
