This widget solves a very            specific problem: namely, if a menu contains check or            radio menu items, GTK+ indents the child widget of all            the menu items in the menu to make room for the check            or radio buttons. Gnome uses pixmaps next to some menu            items; <tt class="CLASSNAME">GtkPixmapMenuItem</tt>            indents pixmaps in the same way GTK+ indents check or            radio buttons. If you simply added a pixmap and a label            to a <tt class="CLASSNAME">GtkMenuItem</tt>, the pixmap            would be incorrectly aligned with the plain labels in            other menu items. This widget is not really            pixmap-specific; any widget can be placed in the            unindented "pixmap" slot. Usually <tt class=            "CLASSNAME">GtkPixmapMenuItem</tt> is created            implicitly with the Gnome menu creation functions.          </p>          <div class="FIGURE">            <a name="Z352"></a>            <p>              <img src="figures/gtkpixmapmenuitem.png">            </p>            <p>              <b>Figure 11. <tt class="CLASSNAME">              GtkPixmapMenuItem</tt> correctly positions pixmaps in              a separate column to the left of the menu item              texts.</b>            </p>          </div>        </div>      </div>      <div class="SECT2">        <h2 class="SECT2">          <a name="Z353"><tt class="CLASSNAME">          GtkTearoffMenuItem</tt></a>        </h2>        <div class="SECT3">          <h3 class="SECT3">            <a name="Z354">Library</a>          </h3>          <p>            GTK+          </p>        </div>        <div class="SECT3">          <h3 class="SECT3">            <a name="Z355">Header File</a>          </h3>          <p>            <tt class="FILENAME">gtk/gtktearoffmenuitem.h</tt>          </p>        </div>        <div class="SECT3">          <h3 class="SECT3">            <a name="Z356">Description</a>          </h3>          <p>            <tt class="CLASSNAME">GtkTearoffMenuItem</tt> is a            "perforation" representing a spot where a menu can be            "torn off" (kept visible in a toplevel window for easy            access).
