/// [`Expander`][crate::Expander] allows the user to reveal its child by clicking
/// on an expander triangle.
///
/// 
///
/// This is similar to the triangles used in a [`TreeView`][crate::TreeView].
///
/// Normally you use an expander as you would use a frame; you create
/// the child widget and use [`set_child()`][Self::set_child()] to add it
/// to the expander. When the expander is toggled, it will take care of
/// showing and hiding the child automatically.
///
/// # Special Usage
///
/// There are situations in which you may prefer to show and hide the
/// expanded widget yourself, such as when you want to actually create
/// the widget at expansion time. In this case, create a [`Expander`][crate::Expander]
/// but do not add a child to it. The expander widget has an
/// [`expanded`][struct@crate::Expander#expanded] property which can be used to
/// monitor its expansion state. You should watch this property with
/// a signal connection as follows:
///
/// **⚠️ The following code is in c ⚠️**
///
/// ```c
/// static void
/// expander_callback (GObject *object,
/// GParamSpec *param_spec,
/// gpointer user_data)
/// {
/// GtkExpander *expander;
///
/// expander = GTK_EXPANDER (object);
///
/// if (gtk_expander_get_expanded (expander))
/// {
/// // Show or create widgets
/// }
/// else
/// {
/// // Hide or destroy widgets
/// }
/// }
///
/// static void
/// create_expander (void)
/// {
/// GtkWidget *expander = gtk_expander_new_with_mnemonic ("_More Options");
/// g_signal_connect (expander, "notify::expanded",
/// G_CALLBACK (expander_callback), NULL);
///
/// // ...
/// }
/// ```
///
/// # GtkExpander as GtkBuildable
///
/// The [`Expander`][crate::Expander] implementation of the [`Buildable`][crate::Buildable] interface supports
/// placing a child in the label position by specifying “label” as the
/// “type” attribute of a `<child>` element. A normal content child can be
/// specified without specifying a `<child>` type attribute.
///
/// An example of a UI definition fragment with GtkExpander:
///
/// ```xml
/// <object class="GtkExpander">
/// <child type="label">
/// <object class="GtkLabel" id="expander-label"/>
/// </child>
/// <child>
/// <object class="GtkEntry" id="expander-content"/>
/// </child>
/// </object>
/// ```
///
/// # CSS nodes
///
/// ```text
/// expander-widget
/// ╰── box
/// ├── title
/// │ ├── expander
/// │ ╰── <label widget>
/// ╰── <child>
/// ```
///
/// [`Expander`][crate::Expander] has a main node `expander-widget`, and subnode `box` containing
/// the title and child widget. The box subnode `title` contains node `expander`,
/// i.e. the expand/collapse arrow; then the label widget if any. The arrow of an
/// expander that is showing its child gets the `:checked` pseudoclass set on it.
///
/// # Accessibility
///
/// [`Expander`][crate::Expander] uses the [`AccessibleRole::Button`][crate::AccessibleRole::Button] role.

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

///
/// May result in finalization of the widget if all references are released.
///
/// This signal is not suitable for saving widget state.
///
///
///
///
/// #### `direction-changed`
/// Emitted when the text direction of a widget changes.
///
///
///
///
/// #### `hide`
/// Emitted when @widget is hidden.
///
///
///
///
/// #### `keynav-failed`
/// Emitted if keyboard navigation fails.
///
/// 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).

///
///
/// #### `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.
