===================================================================

.. currentmodule:: gi.repository.Gtk





.. class:: FlowBoxChild(**properties: ~typing.Any)
   :no-contents-entry:


Superclasses: :class:`~gi.repository.Gtk.Widget`, :class:`~gi.repository.GObject.InitiallyUnowned`, :class:`~gi.repository.GObject.Object`



Implemented Interfaces: :class:`~gi.repository.Gtk.Accessible`, :class:`~gi.repository.Gtk.Buildable`, :class:`~gi.repository.Gtk.ConstraintTarget`



``GtkFlowBoxChild`` is the kind of widget that can be added to a ``GtkFlowBox``.



Constructors
------------

.. rst-class:: interim-class

.. class:: FlowBoxChild
   :no-index:


   .. classmethod:: new() -> ~gi.repository.Gtk.Widget

      Creates a new ``GtkFlowBoxChild``.

      This should only be used as a child of a ``GtkFlowBox``.














Methods
-------

.. rst-class:: interim-class

.. class:: FlowBoxChild
   :no-index:


   .. method:: changed() -> None

      Marks ``child`` as changed, causing any state that depends on this
      to be updated.

      This affects sorting and filtering.

      Note that calls to this method must be in sync with the data
      used for the sorting and filtering functions. For instance, if
      the list is mirroring some external data set, and *two* children
      changed in the external data set when you call
      :func:`~gi.repository.Gtk.FlowBoxChild.changed` on the first child, the sort function
      must only read the new data for the first of the two changed
      children, otherwise the resorting of the children will be wrong.

      This generally means that if you don’t fully control the data
      model, you have to duplicate the data that affects the sorting
      and filtering functions into the widgets themselves.

      Another alternative is to call :obj:`~gi.repository.Gtk.FlowBox.invalidate_sort`
      on any model change, but that is more expensive.










   .. method:: get_child() -> ~gi.repository.Gtk.Widget | None

      Gets the child widget of ``self``.










   .. method:: get_index() -> int

      Gets the current index of the ``child`` in its ``GtkFlowBox`` container.










   .. method:: is_selected() -> bool

      Returns whether the ``child`` is currently selected in its
      ``GtkFlowBox`` container.










   .. method:: set_child(child: ~gi.repository.Gtk.Widget | None = None) -> None

      Sets the child widget of ``self``.







      :param child: the child widget









Properties
----------

.. rst-class:: interim-class

.. class:: FlowBoxChild
   :no-index:
   

   .. attribute:: props.child
      :type: ~gi.repository.Gtk.Widget

      The child widget.











Signals
-------

.. rst-class:: interim-class

.. class:: FlowBoxChild.signals
   :no-index:
   

   .. method:: activate() -> None

      Emitted when the user activates a child widget in a ``GtkFlowBox``.

      This can happen either by clicking or double-clicking,
      or via a keybinding.

      This is a `keybinding signal <class.SignalAction.html>`_,
      but it can be used by applications for their own purposes.

      The default bindings are :kbd:`Space` and :kbd:`Enter`.
