```c AdwDialog *dialog;

dialog = adw_alert_dialog_new (_("Replace File?"), NULL); adw_alert_dialog_format_body (ADW_ALERT_DIALOG (dialog), _("A file named “ s” already exists. Do you want to replace it?"), filename); ```

Parameters:

heading	the heading
body	the body text

Returns:

the newly created `AdwAlertDialog`
