/// [`DropDown`][crate::DropDown] is a widget that allows the user to choose an item
/// from a list of options.
///
/// 
///
/// The [`DropDown`][crate::DropDown] displays the [selected][`selected`][struct@crate::DropDown#selected]
/// choice.
///
/// The options are given to [`DropDown`][crate::DropDown] in the form of `GListModel`
/// and how the individual options are represented is determined by
/// a [`ListItemFactory`][crate::ListItemFactory]. The default factory displays simple strings,
/// and adds a checkmark to the selected item in the popup.
///
/// To set your own factory, use [`set_factory()`][Self::set_factory()]. It is
/// possible to use a separate factory for the items in the popup, with
/// [`set_list_factory()`][Self::set_list_factory()].
///
/// [`DropDown`][crate::DropDown] knows how to obtain strings from the items in a
/// [`StringList`][crate::StringList]; for other models, you have to provide an expression
/// to find the strings via [`set_expression()`][Self::set_expression()].
///
/// [`DropDown`][crate::DropDown] can optionally allow search in the popup, which is
/// useful if the list of options is long. To enable the search entry,
/// use [`set_enable_search()`][Self::set_enable_search()].
///
/// Here is a UI definition example for [`DropDown`][crate::DropDown] with a simple model:
///
/// ```xml
/// <object class="GtkDropDown">
/// <property name="model">
/// <object class="GtkStringList">
/// <items>
/// <item translatable="yes">Factory</item>
/// <item translatable="yes">Home</item>
/// <item translatable="yes">Subway</item>
/// </items>
/// </object>
/// </property>
/// </object>
/// ```
///
/// If a [`DropDown`][crate::DropDown] is created in this manner, or with
/// [`from_strings()`][Self::from_strings()], for instance, the object returned from
/// [`selected_item()`][Self::selected_item()] will be a [`StringObject`][crate::StringObject].
///
/// To learn more about the list widget framework, see the
/// [overview](section-list-widget.html).
///
/// ## CSS nodes
///
/// [`DropDown`][crate::DropDown] has a single CSS node with name dropdown,
/// with the button and popover nodes as children.
///
/// ## Accessibility
///
/// [`DropDown`][crate::DropDown] uses the [`AccessibleRole::ComboBox`][crate::AccessibleRole::ComboBox] role.
///
/// ## Properties
///
///
/// #### `enable-search`
/// Whether to show a search entry in the popup.
///
/// Note that search requires [`expression`][struct@crate::DropDown#expression]
/// to be set.
///
/// Readable | Writeable
///
///
/// #### `expression`
/// An expression to evaluate to obtain strings to match against the search
/// term.
///
/// See [`enable-search`][struct@crate::DropDown#enable-search] for how to enable search.
/// If [`factory`][struct@crate::DropDown#factory] is not set, the expression is also
/// used to bind strings to labels produced by a default factory.
///
/// Readable | Writeable
///
///
/// #### `factory`
/// Factory for populating list items.
///
/// Readable | Writeable
///
///
/// #### `header-factory`
/// The factory for creating header widgets for the popup.
///
/// Readable | Writeable
///
///
/// #### `list-factory`
/// The factory for populating list items in the popup.

/// If this is not set, [`factory`][struct@crate::DropDown#factory] is used.

/// 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 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.
