A scrollable :obj:`~gi.repository.Adw.Clamp`\.

``AdwClampScrollable`` is a variant of :obj:`~gi.repository.Adw.Clamp` that implements the
:obj:`~gi.repository.Gtk.Scrollable` interface.

The primary use case for ``AdwClampScrollable`` is clamping
:obj:`~gi.repository.Gtk.ListView`\.

See also: :obj:`~gi.repository.Adw.ClampLayout`\.


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

.. rst-class:: interim-class

.. class:: ClampScrollable
   :no-index:


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

      Creates a new ``AdwClampScrollable``\.













Methods
-------

.. rst-class:: interim-class

.. class:: ClampScrollable
   :no-index:


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

      Gets the child widget of ``self``\.









   .. method:: get_maximum_size() -> int

      Gets the maximum size allocated to the child.









   .. method:: get_tightening_threshold() -> int

      Gets the size above which the child is clamped.









   .. method:: get_unit() -> ~gi.repository.Adw.LengthUnit

      Gets the length unit for maximum size and tightening threshold.


      .. versionadded:: 1.4








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

      Sets the child widget of ``self``\.






      :param child: the child widget




   .. method:: set_maximum_size(maximum_size: int) -> None

      Sets the maximum size allocated to the child.

      It is the width if the clamp is horizontal, or the height if it is vertical.






      :param maximum_size: the maximum size




   .. method:: set_tightening_threshold(tightening_threshold: int) -> None

      Sets the size above which the child is clamped.

      Starting from this size, the clamp will tighten its grip on the child, slowly
      allocating less and less of the available size up to the maximum allocated
      size. Below that threshold and below the maximum width, the child will be
      allocated all the available size.

      If the threshold is greater than the maximum size to allocate to the child,
      the child will be allocated all the width up to the maximum. If the threshold
      is lower than the minimum size to allocate to the child, that size will be
      used as the tightening threshold.

      Effectively, tightening the grip on the child before it reaches its maximum
      size makes transitions to and from the maximum size smoother when resizing.






      :param tightening_threshold: the tightening threshold




   .. method:: set_unit(unit: ~gi.repository.Adw.LengthUnit) -> None

      Sets the length unit for maximum size and tightening threshold.

      Allows the sizes to vary depending on the text scale factor.

      :param unit: the length unit
