<summary>Encapsulates an adjustable bounded value.</summary>
<remarks>
<para>The Adjustment object represents a value with an associated <see cref="P:Gtk.Adjustment.Lower" /> and <see cref="P:Gtk.Adjustment.Upper" /> bound, together with a <see cref="P:Gtk.Adjustment.StepIncrement" />, <see cref="P:Gtk.Adjustment.PageIncrement" />, and a <see cref="P:Gtk.Adjustment.PageSize" />.</para>
<para>The Adjustment object does not update the value itself. Instead it is left up to the owner of the Adjustment to control the value. The owner of the Adjustment typically calls the <see cref="M:Gtk.Adjustment.ValueChanged" /> and <see cref="M:Gtk.Adjustment.Changed" /> methods after changing the value or its bounds, respectively. This results in the emission of the <see cref="F:Gtk.Adjustment.ValueChanged" /> or <see cref="F:Gtk.Adjustment.Changed" /> events respectively.</para>
<para>An Adjustment is used within several widgets, including <see cref="T:Gtk.SpinButton" />, <see cref="T:Gtk.Viewport" />, and <see cref="T:Gtk.Range" /> (which is a base class for <see cref="T:Gtk.HScrollbar" />, <see cref="T:Gtk.VScrollbar" />, <see cref="T:Gtk.HScale" />, and <see cref="T:Gtk.VScale" />).</para>
