+ * This class is a widget showing a lineedit and a button, which invokes a
+ * filedialog. File name completion is available in the lineedit.
+ *
+ * The defaults for the filedialog are to ask for one existing local file, i.e.
+ * KFileDialog::setMode( KFile::File | KFile::ExistingOnly | KFile::LocalOnly )
+ * The default filter is "*", i.e. show all files, and the start directory is
+ * the current working directory, or the last directory where a file has been
+ * selected.
+ *
+ * You can change this behavior by using setMode() or setFilter().
