    ///
    /// See [`default-filter`][struct@crate::FileDialog#default-filter] about how those two properties interact.
    ///
    /// Readable | Writeable
    ///
    ///
    /// #### `initial-file`
    ///  The initial file, that is, the file that is initially selected
    /// in the file chooser dialog
    ///
    /// This is a utility property that sets both [`initial-folder`][struct@crate::FileDialog#initial-folder] and
    /// [`initial-name`][struct@crate::FileDialog#initial-name].

    /// selected in the file chooser dialog.
    ///
    /// Readable | Writeable
    ///
    ///
    /// #### `modal`
