    /// ## Properties
    ///
    ///
    /// #### `icon`
    ///  The "icon" property contains a [`gio::Icon`][crate::gio::Icon] that describes the save
    /// operation. Generally, this should be the symbolic icon of the
    /// document class you are saving.
    ///
    /// Alternatively, you can use [`icon-name`][struct@crate::SaveDelegate#icon-name] for a
    /// named icon.
    ///
    /// Readable | Writeable
    ///
    ///
    /// #### `icon-name`
    ///  The "icon-name" property contains the name of an icon to use when
    /// showing information about the save operation in UI such as a save
    /// dialog.
    ///
    /// You can also use [`icon`][struct@crate::SaveDelegate#icon] to set a [`gio::Icon`][crate::gio::Icon] instead of
    /// an icon name.
    ///
    /// Readable | Writeable
    ///
    ///
    /// #### `is-draft`
    ///  The "is-draft" property indicates that the document represented by the
    /// delegate is a draft and might be lost of not saved.
    ///
    /// Readable | Writeable
    ///
    ///
    /// #### `progress`
    ///  The "progress" property contains progress between 0.0 and 1.0 and
    /// should be updated by the delegate implementation as saving progresses.
    ///
    /// Readable | Writeable
    ///
    ///
    /// #### `subtitle`
    ///  The "subtitle" property contains additional information that may
    /// not make sense to put in the title. This might include the directory
    /// that the file will be saved within.
    ///
    /// Readable | Writeable
    ///
    ///
    /// #### `title`
    ///  The "title" property contains the title of the document being saved.
    /// Generally, this should be the base name of the document such as
    /// `file.txt`.
    ///
    /// Readable | Writeable
    ///
    /// ## Signals
    ///
    ///
    /// #### `close`
    ///  This signal is emitted when the save delegate should close
    /// the widget it is related to. This can happen after saving as
    /// part of a close request and it is now save for the delegate to
    /// close.
    ///
    /// Implementations are encouraged to connect to this signal (or
    /// implement the virtual method) and call [`WidgetExt::force_close()`][crate::prelude::WidgetExt::force_close()].
    ///
    ///
    ///
    ///
    /// #### `discard`
    ///  This signal is emitted when the user has requested that the
    /// delegate discard the changes instead of saving them.
    ///
    /// Implementations are encouraged to connect to this signal (or
    /// implement the virtual method) and revert the document to the
    /// last saved state and/or close the document.
    ///
    ///
    ///
    ///
    /// #### `save`
    ///  This signal can be used when subclassing [`SaveDelegate`][crate::SaveDelegate] is not
    /// possible or cumbersome. The default implementation of
    /// `PanelSaveDelegateClass.save_async()` will emit this signal to allow
    /// the consumer to implement asynchronous save in a flexible manner.
    ///
    /// The caller is expected to complete `task` with a boolean when the
    /// save operation has completed.
