<para>
 
84
The <link linkend="GtkAdjustment"><type>GtkAdjustment</type></link> object represents a value which has an associated lower
 
85
and upper bound, together with step and page increments, and a page size.
 
86
It is used within several GTK+ widgets, including
 
87
<link linkend="GtkSpinButton"><type>GtkSpinButton</type></link>, <link linkend="GtkViewport"><type>GtkViewport</type></link>, and <link linkend="GtkRange"><type>GtkRange</type></link> (which is a base class for
 
88
<link linkend="GtkHScrollbar"><type>GtkHScrollbar</type></link>, <link linkend="GtkVScrollbar"><type>GtkVScrollbar</type></link>, <link linkend="GtkHScale"><type>GtkHScale</type></link>, and <link linkend="GtkVScale"><type>GtkVScale</type></link>).

</para>
 
90
<para>
 
91
The <link linkend="GtkAdjustment"><type>GtkAdjustment</type></link> object does not update the value itself. Instead
 
92
it is left up to the owner of the <link linkend="GtkAdjustment"><type>GtkAdjustment</type></link> to control the value.
 
93
</para>
 
94
<para>
 
95
The owner of the <link linkend="GtkAdjustment"><type>GtkAdjustment</type></link> typically calls the
 
96
<link linkend="gtk-adjustment-value-changed"><function>gtk_adjustment_value_changed()</function></link> and <link linkend="gtk-adjustment-changed"><function>gtk_adjustment_changed()</function></link> functions
 
97
after changing the value and its bounds. This results in the emission of the
 
98
&quot;value_changed&quot; or &quot;changed&quot; signal respectively.

If the range is larger than the page size, then only the start of it will

be in the current page.

A &quot;changed&quot; signal will be emitted if the value is changed.
