/// Dialog for selecting a file to open.
///
/// This dialog is a costumizable dialog and is to be used for all editors.
/// It offers the choice between a default (current) file, a prepared selection of 
/// files, choosing an arbitrary file from somewhere or creating a new file.
/// Before using the dialog you have to set it up. You can do this using the
/// all-in-one function requestFileToOpen() or manually by setting the 
/// different widgets yourself. Usually the first proposal will be best, as 
/// in the following example:
/// @code
/// KTouchOpenRequest dlg;
/// KURL url;
/// // current_lecture must hold the URL to the current/default lecture or ""
/// // default_lectures must be a TQStringList with the default lecture files.
/// int result = dlg.requestFileToOpen(url, i18n("Open a lecture file"), 
///     i18n("Which lecture would you like to open?"), i18n("Current lecture:"), 
///     i18n("Open a default lecture:"), i18n("Open a lecture file:"), 
///     i18n("Create a new lecture!"), current_lecture, 
///     default_lectures, i18n("<no lecture files available>"));
///
/// if (result==TQDialog::Accepted) {
///     doSomethingFancyWith(url);
/// }
/// @endcode
/// If you don't use the function and execute the dialog manually, the chosen
/// url is stored in the member variable m_url (if the dialog was accepted by 
/// the user).
