Re: file selection

[Paul Santa Maria <paulsm1021 yahoo com>]

Hi -

No - actually, all you need to do is:

  1. Launch the file selection dialog
  2. Check the return value

I've cut/pasted an example below.

'Hope that helps .. PSM
===============================================================

// Prototype
GtkWidget * mk_file_chooser ();

/*****************************************************************************
 * file_open_cb: "File, Open" event handler
 *
 * NOTES:
 * - file_open_cb can be called either via "File, Open" menu option or 
 *   "File Open" toolbar.
 *
 * - It merely gets the filename and notifies the application object 
 *   (via the "setNewFileName ()" method) to actually read the file 
 *   and re-draw the image.
 *****************************************************************************
 */
void
file_open_cb (GtkWidget *widget, gpointer data)
{
  // Create file dialog
  GtkWidget *filesel = mk_file_chooser ();

  // Run as a modal dialog: use gtk_dialog_run() (vs. "gtk_widget_show ()")
  gint result = gtk_dialog_run (GTK_DIALOG(filesel));

  // If GTK_RESPONSE_ACCEPT (-5), then notify the application object
  switch (result)
  {
    case GTK_RESPONSE_OK:
    case GTK_RESPONSE_ACCEPT:
      theApp->setNewFileName (
        gtk_file_selection_get_filename (
          GTK_FILE_SELECTION (filesel)));
      break;
    case GTK_RESPONSE_CANCEL:
    default:
      fprintf (stderr, "NO ACTION: File selection CANCELLED!\n");
      break;
  }

  // Done: de-allocate the dialog
  gtk_widget_destroy (filesel);

}

/*****************************************************************************
 * mk_file_chooser: Create popup file selection dialog
 *****************************************************************************
 */
GtkWidget *
mk_file_chooser ()
{
  GtkWidget *filew = gtk_file_selection_new ("File selection");

  // Disable the (dangerous!) "rename file" and "delete file" options
  gtk_file_selection_hide_fileop_buttons (GTK_FILE_SELECTION (filew));

  // Set filename
  gtk_file_selection_set_filename (GTK_FILE_SELECTION(filew),
    "data/*.hbs");

  /* NOTE:
   * We do *not* need to register any callbacks: we'll just check
   * the return status and, if GTK_RESPONSE_OK (-5), we'll read the filename
   */
  return filew;
}

why don't you take a look at the gtk_file_chooser's source code ?
