/// [`Editable`][crate::Editable] is an interface for text editing widgets.
///
/// Typical examples of editable widgets are [`Entry`][crate::Entry] and
/// [`SpinButton`][crate::SpinButton]. It contains functions for generically manipulating
/// an editable widget, a large number of action signals used for key bindings,
/// and several signals that an application can connect to modify the behavior
/// of a widget.
///
/// As an example of the latter usage, by connecting the following handler to
/// [`insert-text`][struct@crate::Editable#insert-text], an application can convert all entry
/// into a widget into uppercase.
///
/// ## Forcing entry to uppercase.
///
/// **⚠️ The following code is in c ⚠️**
///
/// ```c
/// #include <ctype.h>
///
/// void
/// insert_text_handler (GtkEditable *editable,
/// const char *text,
/// int length,
/// int *position,
/// gpointer data)
/// {
/// char *result = g_utf8_strup (text, length);
///
/// g_signal_handlers_block_by_func (editable,
/// (gpointer) insert_text_handler, data);
/// gtk_editable_insert_text (editable, result, length, position);
/// g_signal_handlers_unblock_by_func (editable,
/// (gpointer) insert_text_handler, data);
///
/// g_signal_stop_emission_by_name (editable, "insert_text");
///
/// g_free (result);
/// }
/// ```
///
/// ## Implementing GtkEditable
///
/// The most likely scenario for implementing [`Editable`][crate::Editable] on your own widget
/// is that you will embed a [`Text`][crate::Text] inside a complex widget, and want to
/// delegate the editable functionality to that text widget. [`Editable`][crate::Editable]
/// provides some utility functions to make this easy.
///
/// In your class_init function, call [`install_properties()`][Self::install_properties()],
/// passing the first available property ID:
///
/// **⚠️ The following code is in c ⚠️**
///
/// ```c
/// static void
/// my_class_init (MyClass *class)
/// {
/// ...
/// g_object_class_install_properties (object_class, NUM_PROPERTIES, props);
/// gtk_editable_install_properties (object_clas, NUM_PROPERTIES);
/// ...
/// }
/// ```
///
/// In your interface_init function for the [`Editable`][crate::Editable] interface, provide
/// an implementation for the get_delegate vfunc that returns your text widget:
///
/// **⚠️ The following code is in c ⚠️**
///
/// ```c
/// GtkEditable *
/// get_editable_delegate (GtkEditable *editable)
/// {
/// return GTK_EDITABLE (MY_WIDGET (editable)->text_widget);
/// }
///
/// static void
/// my_editable_init (GtkEditableInterface *iface)
/// {
/// iface->get_delegate = get_editable_delegate;
/// }
/// ```
///
/// You don't need to provide any other vfuncs. The default implementations
/// work by forwarding to the delegate that the GtkEditableInterface.get_delegate()
/// vfunc returns.
///
/// In your instance_init function, create your text widget, and then call
/// [`EditableExt::init_delegate()`][crate::prelude::EditableExt::init_delegate()]:
///
/// **⚠️ The following code is in c ⚠️**
///
/// ```c
/// static void
/// my_widget_init (MyWidget *self)
/// {
/// ...
/// self->text_widget = gtk_text_new ();
/// gtk_editable_init_delegate (GTK_EDITABLE (self));
/// ...
/// }
/// ```
///
/// In your dispose function, call [`EditableExt::finish_delegate()`][crate::prelude::EditableExt::finish_delegate()] before
/// destroying your text widget:
///
/// **⚠️ The following code is in c ⚠️**
///
/// ```c
/// static void
/// my_widget_dispose (GObject *object)
/// {
/// ...
/// gtk_editable_finish_delegate (GTK_EDITABLE (self));
/// g_clear_pointer (&self->text_widget, gtk_widget_unparent);
/// ...
/// }
/// ```
///
/// Finally, use [`delegate_set_property()`][Self::delegate_set_property()] in your `set_property`
/// function (and similar for `get_property`), to set the editable properties:
///
/// **⚠️ The following code is in c ⚠️**
///
/// ```c
/// ...
/// if (gtk_editable_delegate_set_property (object, prop_id, value, pspec))
/// return;
///
/// switch (prop_id)
/// ...
/// ```
///
/// It is important to note that if you create a [`Editable`][crate::Editable] that uses
/// a delegate, the low level [`insert-text`][struct@crate::Editable#insert-text] and
/// [`delete-text`][struct@crate::Editable#delete-text] signals will be propagated from the
/// "wrapper" editable to the delegate, but they will not be propagated from
/// the delegate to the "wrapper" editable, as they would cause an infinite
/// recursion. If you wish to connect to the [`insert-text`][struct@crate::Editable#insert-text]
/// and [`delete-text`][struct@crate::Editable#delete-text] signals, you will need to connect
/// to them on the delegate obtained via [`EditableExt::delegate()`][crate::prelude::EditableExt::delegate()].
///

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

///
/// #### `map`

/// 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

///
/// The `::map` signal can be used to determine whether a widget will be drawn,

/// 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`

///
/// 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`
