/// List views use widgets for displaying their

/// An abstract class for laying out [`CellRenderer`][crate::CellRenderer]s
///
/// The [`CellArea`][crate::CellArea] is an abstract class for [`CellLayout`][crate::CellLayout]
/// widgets (also referred to as "layouting widgets") to interface with
/// an arbitrary number of [`CellRenderer`][crate::CellRenderer]s and interact with the user
/// for a given [`TreeModel`][crate::TreeModel] row.
///
/// The cell area handles events, focus navigation, drawing and
/// size requests and allocations for a given row of data.
///
/// Usually users dont have to interact with the [`CellArea`][crate::CellArea] directly
/// unless they are implementing a cell-layouting widget themselves.
///
/// ## Requesting area sizes
///
/// As outlined in
/// [GtkWidget’s geometry management section](class.Widget.html#height-for-width-geometry-management),
/// GTK uses a height-for-width
/// geometry management system to compute the sizes of widgets and user
/// interfaces. [`CellArea`][crate::CellArea] uses the same semantics to calculate the
/// size of an area for an arbitrary number of [`TreeModel`][crate::TreeModel] rows.
///
/// When requesting the size of a cell area one needs to calculate
/// the size for a handful of rows, and this will be done differently by
/// different layouting widgets. For instance a [`TreeViewColumn`][crate::TreeViewColumn]
/// always lines up the areas from top to bottom while a [`IconView`][crate::IconView]
/// on the other hand might enforce that all areas received the same
/// width and wrap the areas around, requesting height for more cell
/// areas when allocated less width.
///
/// It’s also important for areas to maintain some cell
/// alignments with areas rendered for adjacent rows (cells can
/// appear “columnized” inside an area even when the size of
/// cells are different in each row). For this reason the [`CellArea`][crate::CellArea]
/// uses a [`CellAreaContext`][crate::CellAreaContext] object to store the alignments
/// and sizes along the way (as well as the overall largest minimum
/// and natural size for all the rows which have been calculated
/// with the said context).
///
/// The [`CellAreaContext`][crate::CellAreaContext] is an opaque object specific to the
/// [`CellArea`][crate::CellArea] which created it (see [`CellAreaExt::create_context()`][crate::prelude::CellAreaExt::create_context()]).
///
/// The owning cell-layouting widget can create as many contexts as
/// it wishes to calculate sizes of rows which should receive the
/// same size in at least one orientation (horizontally or vertically),
/// However, it’s important that the same [`CellAreaContext`][crate::CellAreaContext] which
/// was used to request the sizes for a given [`TreeModel`][crate::TreeModel] row be
/// used when rendering or processing events for that row.
///
/// In order to request the width of all the rows at the root level
/// of a [`TreeModel`][crate::TreeModel] one would do the following:
///
/// **⚠️ The following code is in c ⚠️**
///
/// ```c
/// GtkTreeIter iter;
/// int minimum_width;
/// int natural_width;
///
/// valid = gtk_tree_model_get_iter_first (model, &iter);
/// while (valid)
/// {
/// gtk_cell_area_apply_attributes (area, model, &iter, FALSE, FALSE);
/// gtk_cell_area_get_preferred_width (area, context, widget, NULL, NULL);
///
/// valid = gtk_tree_model_iter_next (model, &iter);
/// }
///
/// gtk_cell_area_context_get_preferred_width (context, &minimum_width, &natural_width);
/// ```
///
/// Note that in this example it’s not important to observe the
/// returned minimum and natural width of the area for each row
/// unless the cell-layouting object is actually interested in the
/// widths of individual rows. The overall width is however stored
/// in the accompanying [`CellAreaContext`][crate::CellAreaContext] object and can be consulted
/// at any time.
///
/// This can be useful since [`CellLayout`][crate::CellLayout] widgets usually have to
/// support requesting and rendering rows in treemodels with an
/// exceedingly large amount of rows. The [`CellLayout`][crate::CellLayout] widget in
/// that case would calculate the required width of the rows in an
/// idle or timeout source (see `timeout_add()`) and when the widget
/// is requested its actual width in [`WidgetImpl::measure()`][crate::subclass::prelude::WidgetImpl::measure()]
/// it can simply consult the width accumulated so far in the
/// [`CellAreaContext`][crate::CellAreaContext] object.
///
/// A simple example where rows are rendered from top to bottom and
/// take up the full width of the layouting widget would look like:
///
/// **⚠️ The following code is in c ⚠️**
///
/// ```c
/// static void
/// foo_get_preferred_width (GtkWidget *widget,
/// int *minimum_size,
/// int *natural_size)
/// {
/// Foo *self = FOO (widget);
/// FooPrivate *priv = foo_get_instance_private (self);
///
/// foo_ensure_at_least_one_handfull_of_rows_have_been_requested (self);
///
/// gtk_cell_area_context_get_preferred_width (priv->context, minimum_size, natural_size);
/// }
/// ```
///
/// In the above example the `Foo` widget has to make sure that some
/// row sizes have been calculated (the amount of rows that `Foo` judged
/// was appropriate to request space for in a single timeout iteration)
/// before simply returning the amount of space required by the area via
/// the [`CellAreaContext`][crate::CellAreaContext].
///
/// Requesting the height for width (or width for height) of an area is
/// a similar task except in this case the [`CellAreaContext`][crate::CellAreaContext] does not
/// store the data (actually, it does not know how much space the layouting
/// widget plans to allocate it for every row. It’s up to the layouting
/// widget to render each row of data with the appropriate height and
/// width which was requested by the [`CellArea`][crate::CellArea]).
///
/// In order to request the height for width of all the rows at the
/// root level of a [`TreeModel`][crate::TreeModel] one would do the following:
///
/// **⚠️ The following code is in c ⚠️**
///
/// ```c
/// GtkTreeIter iter;
/// int minimum_height;
/// int natural_height;
/// int full_minimum_height = 0;
/// int full_natural_height = 0;
///
/// valid = gtk_tree_model_get_iter_first (model, &iter);
/// while (valid)
/// {
/// gtk_cell_area_apply_attributes (area, model, &iter, FALSE, FALSE);
/// gtk_cell_area_get_preferred_height_for_width (area, context, widget,
/// width, &minimum_height, &natural_height);
///
/// if (width_is_for_allocation)
/// cache_row_height (&iter, minimum_height, natural_height);
///
/// full_minimum_height += minimum_height;
/// full_natural_height += natural_height;
///
/// valid = gtk_tree_model_iter_next (model, &iter);
/// }
/// ```
///
/// Note that in the above example we would need to cache the heights
/// returned for each row so that we would know what sizes to render the
/// areas for each row. However we would only want to really cache the
/// heights if the request is intended for the layouting widgets real
/// allocation.
///
/// In some cases the layouting widget is requested the height for an
/// arbitrary for_width, this is a special case for layouting widgets
/// who need to request size for tens of thousands of rows. For this
/// case it’s only important that the layouting widget calculate
/// one reasonably sized chunk of rows and return that height
/// synchronously. The reasoning here is that any layouting widget is
/// at least capable of synchronously calculating enough height to fill
/// the screen height (or scrolled window height) in response to a single
/// call to [`WidgetImpl::measure()`][crate::subclass::prelude::WidgetImpl::measure()]. Returning
/// a perfect height for width that is larger than the screen area is
/// inconsequential since after the layouting receives an allocation
/// from a scrolled window it simply continues to drive the scrollbar
/// values while more and more height is required for the row heights
/// that are calculated in the background.
///
/// ## Rendering Areas
///
/// Once area sizes have been acquired at least for the rows in the
/// visible area of the layouting widget they can be rendered at
/// [`WidgetImpl::snapshot()`][crate::subclass::prelude::WidgetImpl::snapshot()] time.
///
/// A crude example of how to render all the rows at the root level
/// runs as follows:
///
/// **⚠️ The following code is in c ⚠️**
///
/// ```c
/// GtkAllocation allocation;
/// GdkRectangle cell_area = { 0, };
/// GtkTreeIter iter;
/// int minimum_width;
/// int natural_width;
///
/// gtk_widget_get_allocation (widget, &allocation);
/// cell_area.width = allocation.width;
///
/// valid = gtk_tree_model_get_iter_first (model, &iter);
/// while (valid)
/// {
/// cell_area.height = get_cached_height_for_row (&iter);
///
/// gtk_cell_area_apply_attributes (area, model, &iter, FALSE, FALSE);
/// gtk_cell_area_render (area, context, widget, cr,
/// &cell_area, &cell_area, state_flags, FALSE);
///
/// cell_area.y += cell_area.height;
///
/// valid = gtk_tree_model_iter_next (model, &iter);
/// }
/// ```
///
/// Note that the cached height in this example really depends on how
/// the layouting widget works. The layouting widget might decide to
/// give every row its minimum or natural height or, if the model content
/// is expected to fit inside the layouting widget without scrolling, it
/// would make sense to calculate the allocation for each row at
/// the time the widget is allocated using `distribute_natural_allocation()`.
///
/// ## Handling Events and Driving Keyboard Focus
///
/// Passing events to the area is as simple as handling events on any
/// normal widget and then passing them to the [`CellAreaExt::event()`][crate::prelude::CellAreaExt::event()]
/// API as they come in. Usually [`CellArea`][crate::CellArea] is only interested in
/// button events, however some customized derived areas can be implemented
/// who are interested in handling other events. Handling an event can
/// trigger the [`focus-changed`][struct@crate::CellArea#focus-changed] signal to fire; as well
/// as [`add-editable`][struct@crate::CellArea#add-editable] in the case that an editable cell
/// was clicked and needs to start editing. You can call
/// [`CellAreaExt::stop_editing()`][crate::prelude::CellAreaExt::stop_editing()] at any time to cancel any cell editing
/// that is currently in progress.
///
/// The [`CellArea`][crate::CellArea] drives keyboard focus from cell to cell in a way
/// similar to [`Widget`][crate::Widget]. For layouting widgets that support giving
/// focus to cells it’s important to remember to pass `GTK_CELL_RENDERER_FOCUSED`
/// to the area functions for the row that has focus and to tell the
/// area to paint the focus at render time.
///
/// Layouting widgets that accept focus on cells should implement the
/// [`WidgetImpl::focus()`][crate::subclass::prelude::WidgetImpl::focus()] virtual method. The layouting widget is always
/// responsible for knowing where [`TreeModel`][crate::TreeModel] rows are rendered inside
/// the widget, so at [`WidgetImpl::focus()`][crate::subclass::prelude::WidgetImpl::focus()] time the layouting widget
/// should use the [`CellArea`][crate::CellArea] methods to navigate focus inside the area
/// and then observe the [`DirectionType`][crate::DirectionType] to pass the focus to adjacent
/// rows and areas.
///
/// A basic example of how the [`WidgetImpl::focus()`][crate::subclass::prelude::WidgetImpl::focus()] virtual method
/// should be implemented:
///
/// ```text
/// static gboolean
/// foo_focus (GtkWidget *widget,
/// GtkDirectionType direction)
/// {
/// Foo *self = FOO (widget);
/// FooPrivate *priv = foo_get_instance_private (self);
/// int focus_row = priv->focus_row;
/// gboolean have_focus = FALSE;
///
/// if (!gtk_widget_has_focus (widget))
/// gtk_widget_grab_focus (widget);
///
/// valid = gtk_tree_model_iter_nth_child (priv->model, &iter, NULL, priv->focus_row);
/// while (valid)
/// {
/// gtk_cell_area_apply_attributes (priv->area, priv->model, &iter, FALSE, FALSE);
///
/// if (gtk_cell_area_focus (priv->area, direction))
/// {
/// priv->focus_row = focus_row;
/// have_focus = TRUE;
/// break;
/// }
/// else
/// {
/// if (direction == GTK_DIR_RIGHT ||
/// direction == GTK_DIR_LEFT)
/// break;
/// else if (direction == GTK_DIR_UP ||
/// direction == GTK_DIR_TAB_BACKWARD)
/// {
/// if (focus_row == 0)
/// break;
/// else
/// {
/// focus_row--;
/// valid = gtk_tree_model_iter_nth_child (priv->model, &iter, NULL, focus_row);
/// }
/// }
/// else
/// {
/// if (focus_row == last_row)
/// break;
/// else
/// {
/// focus_row++;
/// valid = gtk_tree_model_iter_next (priv->model, &iter);
/// }
/// }
/// }
/// }
/// return have_focus;
/// }
/// ```
///
/// Note that the layouting widget is responsible for matching the
/// [`DirectionType`][crate::DirectionType] values to the way it lays out its cells.
///
/// ## Cell Properties
///
/// The [`CellArea`][crate::CellArea] introduces cell properties for [`CellRenderer`][crate::CellRenderer]s.
/// This provides some general interfaces for defining the relationship
/// cell areas have with their cells. For instance in a [`CellAreaBox`][crate::CellAreaBox]
/// a cell might “expand” and receive extra space when the area is allocated
/// more than its full natural request, or a cell might be configured to “align”
/// with adjacent rows which were requested and rendered with the same
/// [`CellAreaContext`][crate::CellAreaContext].
///
/// Use [`CellAreaClassExt::install_cell_property()`][crate::subclass::prelude::CellAreaClassExt::install_cell_property()] to install cell
/// properties for a cell area class and [`CellAreaClassExt::find_cell_property()`][crate::subclass::prelude::CellAreaClassExt::find_cell_property()]
/// or [`CellAreaClassExt::list_cell_properties()`][crate::subclass::prelude::CellAreaClassExt::list_cell_properties()] to get information about
/// existing cell properties.
///
/// To set the value of a cell property, use [`CellAreaExtManual::cell_set_property()`][crate::prelude::CellAreaExtManual::cell_set_property()],
/// `Gtk::CellArea::cell_set()` or `Gtk::CellArea::cell_set_valist()`. To obtain
/// the value of a cell property, use [`CellAreaExtManual::cell_get_property()`][crate::prelude::CellAreaExtManual::cell_get_property()]
/// `Gtk::CellArea::cell_get()` or `Gtk::CellArea::cell_get_valist()`.
///
/// This is an Abstract Base Class, you cannot instantiate it.
///
/// ## Properties
///
///
/// #### `edit-widget`
/// The widget currently editing the edited cell
///
/// This property is read-only and only changes as
/// a result of a call gtk_cell_area_activate_cell().
///
/// Readable
///
///
/// #### `edited-cell`
/// The cell in the area that is currently edited
///
/// This property is read-only and only changes as
/// a result of a call gtk_cell_area_activate_cell().
///
/// Readable
///
///
/// #### `focus-cell`
/// The cell in the area that currently has focus
///
/// Readable | Writeable
///
/// ## Signals
///
///
/// #### `add-editable`
/// Indicates that editing has started on @renderer and that @editable
/// should be added to the owning cell-layouting widget at @cell_area.
///
///
///
///
/// #### `apply-attributes`
/// This signal is emitted whenever applying attributes to @area from @model
///
///
///
///
/// #### `focus-changed`
/// Indicates that focus changed on this @area. This signal
/// is emitted either as a result of focus handling or event
/// handling.
///
/// It's possible that the signal is emitted even if the
/// currently focused renderer did not change, this is
/// because focus may change to the same renderer in the
/// same cell area for a different row of data.
///
///
///
///
/// #### `remove-editable`
/// Indicates that editing finished on @renderer and that @editable
/// should be removed from the owning cell-layouting widget.
///
