/// [`Overlay`][crate::Overlay] is a container which contains a single main child, on top
/// of which it can place “overlay” widgets.
///
/// 
///
/// The position of each overlay widget is determined by its
/// [`halign`][struct@crate::Widget#halign] and [`valign`][struct@crate::Widget#valign]
/// properties. E.g. a widget with both alignments set to [`Align::Start`][crate::Align::Start]
/// will be placed at the top left corner of the [`Overlay`][crate::Overlay] container,
/// whereas an overlay with halign set to [`Align::Center`][crate::Align::Center] and valign set
/// to [`Align::End`][crate::Align::End] will be placed a the bottom edge of the [`Overlay`][crate::Overlay],
/// horizontally centered. The position can be adjusted by setting the margin
/// properties of the child to non-zero values.
///
/// More complicated placement of overlays is possible by connecting

/// [`Overlay`][crate::Overlay] has a single CSS node with the name “overlay”. Overlay children

///
/// <details><summary><h4>Widget</h4></summary>

///
/// #### `destroy`
/// Signals that all holders of a reference to the widget should release

///
///
///
/// #### `map`
/// Emitted when @widget is going to be mapped.
///
/// A widget is mapped when the widget is visible (which is controlled with
/// [`visible`][struct@crate::Widget#visible]) and all its parents up to the toplevel widget
/// are also visible.
///
/// The ::map signal can be used to determine whether a widget will be drawn,
/// for instance it can resume an animation that was stopped during the
/// emission of [`unmap`][struct@crate::Widget#unmap].
///
///
///
///
/// #### `mnemonic-activate`
/// Emitted when a widget is activated via a mnemonic.
///
/// The default handler for this signal activates @widget if @group_cycling
/// is [`false`], or just makes @widget grab focus if @group_cycling is [`true`].
///
///
///
///
/// #### `move-focus`
/// Emitted when the focus is moved.
///
/// The ::move-focus signal is a [keybinding signal](class.SignalAction.html).

/// and <kbd>Shift</kbd>+<kbd>Tab</kbd> to move backward.
///
/// Action
///
///
/// #### `query-tooltip`
/// Emitted when the widget’s tooltip is about to be shown.
///
/// This happens when the [`has-tooltip`][struct@crate::Widget#has-tooltip] property
/// is [`true`] and the hover timeout has expired with the cursor hovering
/// "above" @widget; or emitted when @widget got focus in keyboard mode.
///
/// Using the given coordinates, the signal handler should determine
/// whether a tooltip should be shown for @widget. If this is the case
/// [`true`] should be returned, [`false`] otherwise. Note that if
/// @keyboard_mode is [`true`], the values of @x and @y are undefined and
/// should not be used.
///
/// The signal handler is free to manipulate @tooltip with the therefore
/// destined function calls.
///
///
///
///
/// #### `realize`
/// Emitted when @widget is associated with a [`gdk::Surface`][crate::gdk::Surface].
///
/// This means that [`WidgetExt::realize()`][crate::prelude::WidgetExt::realize()] has been called
/// or the widget has been mapped (that is, it is going to be drawn).
///
///
///
///
/// #### `show`
/// Emitted when @widget is shown.
///
///
///
///
/// #### `state-flags-changed`
/// Emitted when the widget state changes.
///
/// See [`WidgetExt::state_flags()`][crate::prelude::WidgetExt::state_flags()].
///
///
///
///
/// #### `unmap`
/// Emitted when @widget is going to be unmapped.
///
/// A widget is unmapped when either it or any of its parents up to the
/// toplevel widget have been set as hidden.
///
/// As ::unmap indicates that a widget will not be shown any longer,
/// it can be used to, for example, stop an animation on the widget.
///
///
///
///
/// #### `unrealize`
/// Emitted when the [`gdk::Surface`][crate::gdk::Surface] associated with @widget is destroyed.
///
/// This means that [`WidgetExt::unrealize()`][crate::prelude::WidgetExt::unrealize()] has been called
/// or the widget has been unmapped (that is, it is going to be hidden).
