It lets you set two factors, each in both the X            and Y direction; the <i class="FIRSTTERM">alignment</i>            is 0.0 for left-justified (or top-justified) and 1.0            for right-justified (or bottom-justified). An alignment            of 0.5 centers the child in that direction. The <i            class="FIRSTTERM">scale</i> factor determines how the            child fills extra space it did not request; if 0.0, the            child fills only its requisition. A scale of 1.0 means            that the child always expands to fill all the available            space. (Clearly, a 1.0 scale factor makes the alignment            factor irrelevant.)          </p>        </div>      </div>      <div class="SECT2">        <h2 class="SECT2">          <a name="Z324"><tt class="CLASSNAME">GtkFrame</tt></a>
