<p>            A generic implementation of <span class="STRUCTNAME">            GnomeMDIChild</span>. For complex applications, you may            need to write a custom implementation.          </p>        </div>      </div>      <div class="SECT2">        <h2 class="SECT2">          <a name="Z803"><span class="STRUCTNAME">          GnomeMDI</span></a>        </h2>        <div class="SECT3">          <h3 class="SECT3">            <a name="Z804">Library</a>          </h3>          <p>            Gnome          </p>        </div>        <div class="SECT3">          <h3 class="SECT3">            <a name="Z805">Header File</a>          </h3>          <p>            <tt class="FILENAME">libgnomeui/gnome-mdi.h</tt>          </p>        </div>        <div class="SECT3">          <h3 class="SECT3">            <a name="Z806">Description</a>          </h3>          <p>            <span class="STRUCTNAME">GnomeMDI</span> keeps track of            multiple documents.

Also, users can drag the notebook pages            out of the <tt class="CLASSNAME">GtkWindow</tt>, and            they will be reparented into their own toplevel window.          </p>        </div>      </div>      <div class="SECT2">        <h2 class="SECT2">          <a name="Z807"><span class="STRUCTNAME">          GtkData</span></a>        </h2>        <div class="SECT3">          <h3 class="SECT3">            <a name="Z808">Library</a>          </h3>          <p>            GTK+          </p>        </div>        <div class="SECT3">          <h3 class="SECT3">            <a name="Z809">Header File</a>          </h3>          <p>            <tt class="FILENAME">gtk/gtkdata.h</tt>          </p>        </div>        <div class="SECT3">          <h3 class="SECT3">            <a name="Z810">Description</a>          </h3>          <p>            <span class="STRUCTNAME">GtkData</span> is an abstract            base class for a piece of data that might be shared            between multiple objects.

It can also store a maximum            and minimum value, a "step increment," a "page            increment," and a "page size." Some objects don't use            all the fields in the adjustment, and some interpret            them slightly differently. A <tt class="CLASSNAME">            GtkRange</tt> (including its <tt class="CLASSNAME">            GtkScale</tt> and <tt class="CLASSNAME">            GtkScrollbar</tt> subclasses) will allow the user to            move the slider between the minimum and maximum values.            Clicking the arrows on the end of a <tt class=            "CLASSNAME">GtkScrollbar</tt> nudges the scroll bar by            one "step increment"; clicking them with the middle            button moves one "page increment." The "page size"            determines the size of the scrollbar slider (it's the            length of the "visible" page in the same units as the            overall range). <span class="STRUCTNAME">            GtkAdjustment</span> emits signals when its values            change.          </p>        </div>      </div>      <div class="SECT2">        <h2 class="SECT2">          <a name="Z815"><span class="STRUCTNAME">          GtkTooltips</span></a>        </h2>        <div class="SECT3">          <h3 class="SECT3">            <a name="Z816">Library</a>          </h3>          <p>            GTK+          </p>        </div>        <div class="SECT3">          <h3 class="SECT3">            <a name="Z817">Header File</a>          </h3>          <p>            <tt class="FILENAME">gtk/gtktooltips.h</tt>          </p>        </div>        <div class="SECT3">          <h3 class="SECT3">            <a name="Z818">Description</a>          </h3>          <p>            <span class="STRUCTNAME">GtkTooltips</span> associates            some help text with a widget.
