-/**
- * 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().
