///
///
///
///
/// #### `change-value`
/// Emitted when a scroll action is performed on a range.
///
/// It allows an application to determine the type of scroll event
/// that occurred and the resultant new value. The application can
/// handle the event itself and return [`true`] to prevent further
/// processing. Or, by returning [`false`], it can pass the event to
/// other handlers until the default GTK handler is reached.

/// Action
///
///
/// #### `value-changed`

///
///
/// <details><summary><h4>Widget</h4></summary>
///
///
/// #### `destroy`
/// Signals that all holders of a reference to the widget should release
/// the reference that they hold.
///
/// May result in finalization of the widget if all references are released.
///
/// This signal is not suitable for saving widget state.
///
///
///
///
/// #### `direction-changed`

///
///
///
/// #### `hide`
/// Emitted when @widget is hidden.
///
///
///
///

/// See [`WidgetExt::keynav_failed()`][crate::prelude::WidgetExt::keynav_failed()] for details.
///
///
///
///
/// #### `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).
///
/// The default bindings for this signal are <kbd>Tab</kbd> to move forward,
/// 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).

///
/// 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.
