A class representing an adjustable bounded value.
<p>
The <a class="el" href="classGtk_1_1Adjustment.html">Gtk::Adjustment</a> object represents a value which has an associated lower and upper bound, together with step and page increments, and a page size. It is used within several gtkmm widgets, including <a class="el" href="classGtk_1_1SpinButton.html">Gtk::SpinButton</a>, <a class="el" href="classGtk_1_1Viewport.html">Gtk::Viewport</a>, and <a class="el" href="classGtk_1_1Range.html">Gtk::Range</a> (which is a base class for <a class="el" href="classGtk_1_1HScrollbar.html">Gtk::HScrollbar</a>, <a class="el" href="classGtk_1_1VScrollbar.html">Gtk::VScrollbar</a>, <a class="el" href="classGtk_1_1HScale.html">Gtk::HScale</a>, and <a class="el" href="classGtk_1_1VScale.html">Gtk::VScale</a>).<p>
The <a class="el" href="classGtk_1_1Adjustment.html">Gtk::Adjustment</a> object does not update the value itself. Instead it is left up to the owner of the <a class="el" href="classGtk_1_1Adjustment.html">Gtk::Adjustment</a> to control the value.<p>
The owner of the <a class="el" href="classGtk_1_1Adjustment.html">Gtk::Adjustment</a> typically calls the <a class="el" href="classGtk_1_1Adjustment.html#a9e2a66bf8702196201db86a88da2567">value_changed()</a> and <a class="el" href="classGtk_1_1Adjustment.html#01b4c0118ac26897ac783f041a032765">changed()</a> functions after changing the value and its bounds. This results in the emission of the "value_changed" or "changed" signal respectively.
