name="details"></a><h2>详细描述</h2> QTableSelection类提供对<a href="qtable.html">QTable</a>中的选中区域的处理。<p> <p>选中区域（selection）是QTable中一个单元格的矩形集合。这个矩形集合中的一个叫做锚单元格（anchor cell），它是第一个被选中的单元格。<a href="#init">init</a>()函数设置锚单元格和只包括这个单元格的选中矩形。；<a href="#expandTo">expandTo</a>()函数则把选中矩形扩展为包括其他单元格。<p>有几个查询区域范围的处理函数：<a href="#anchorRow">anchorRow</a>()和<a href="#anchorCol">anchorCol</a>()返回锚的位置；<a href="#leftCol">leftCol</a>()、<a href="#rightCol">rightCol</a>()、<a href="#topRow">topRow</a>()和<a href="#bottomRow">bottomRow</a>()返回矩形的四边。这四个都是选中区域的一部分。<p>一个新生成的QTableSelection是非活动的——<a href="#isActive">isActive</a>()返回FALSE。你必须使用init()和expandTo()以激活它。<p> <p>也参见<a href="qtable.html">QTable</a>、<a href="qtable.html#addSelection">QTable::addSelection</a>()、<a href="qtable.html#selection">QTable::selection</a>()和<a href="advanced.html">高级部件</a>。<hr><h2>成员函数文档</h2><h3 class=fn><a name="QTableSelection"></a>QTableSelection::QTableSelection ()</h3>生成一个非活动的选中区域。使用<a href="#init">init</a>()和<a href="#expandTo">expandTo</a>()来激活它。<h3 class=fn>int <a name="anchorCol"></a>QTableSelection::anchorCol () const</h3> <p>返回选中区域的锚的列。<p> <p>也参见<a href="#anchorRow">anchorRow</a>()和<a href="#expandTo">expandTo</a>()。<h3 class=fn>int <a name="anchorRow"></a>QTableSelection::anchorRow () const</h3> <p>返回选中区域的锚的行。<p> <p>也参见<a href="#anchorCol">anchorCol</a>()和<a href="#expandTo">expandTo</a>()。<h3 class=fn>int <a name="bottomRow"></a>QTableSelection::bottomRow () const</h3> <p>返回选中区域的底行。<p> <p>也参见<a href="#topRow">topRow</a>()、<a href="#leftCol">leftCol</a>()和<a href="#rightCol">rightCol</a>()。<h3 class=fn>void <a name="expandTo"></a>QTableSelection::expandTo ( int row, int col )</h3>把选中区域扩展到包括单元格<em>row</em>、<em>col</em>。新的选中区域矩形是<em>row</em>、<em>col</em>和之前的选中区域矩形的边界范围矩形（bounding rectangle）。调用本函数后，选中区域被激活。<p>如果未调用<a href="#init">init</a>()，本函数什么也不做。<p> <p>也参见<a href="#init">init</a>()和<a href="#isActive">isActive</a>()。<h3 class=fn>void <a name="init"></a>QTableSelection::init ( int row, int col )</h3>把选中区域的锚设置为单元格<em>row</em>、<em>col</em>，并且该选中区域只包含这个单元格。<p>要扩展选中区域以包括其他单元格，调用<a href="#expandTo">expandTo</a>()。<p> <p>也参见<a href="#isActive">isActive</a>()。<h3 class=fn>bool <a name="isActive"></a>QTableSelection::isActive () const</h3> <p>返回选中区域是否激活。选中区域在<a href="#init">init</a>()和<a href="#expandTo">expandTo</a>()被调用之后被激活。<h3 class=fn>int <a name="leftCol"></a>QTableSelection::leftCol () const</h3> <p>返回选中区域的左边列。<p> <p>也参见<a href="#topRow">topRow</a>()、<a href="#bottomRow">bottomRow</a>()和<a href="#rightCol">rightCol</a>()。<h3 class=fn>bool <a name="operator!-eq"></a>QTableSelection::operator!= ( const <a href="qtableselection.html">QTableSelection</a> & s ) const</h3>如果<em>s</em>与选中区域不包含同样的单元格，返回TRUE；否则返回FALSE。<h3 class=fn>bool <a name="operator-eq-eq"></a>QTableSelection::operator== ( const <a href="qtableselection.html">QTableSelection</a> & s ) const</h3>如果<em>s</em>与选中区域包含同样的单元格，返回TRUE；否则返回FALSE。<h3 class=fn>int <a name="rightCol"></a>QTableSelection::rightCol () const</h3> <p>返回选中区域的右边列。<p> <p>也参见<a href="#topRow">topRow</a>()、<a href="#bottomRow">bottomRow</a>()和<a href="#leftCol">leftCol</a>()。<h3 class=fn>int <a name="topRow"></a>QTableSelection::topRow () const</h3> <p>返回选中区域的顶行。<p> <p>也参见<a href="#bottomRow">bottomRow</a>()、<a href="#leftCol">leftCol</a>()和<a href="#rightCol">rightCol</a>()。<!-- eof --><p><address><hr><div align=center><table width=100% cellspacing=0 border=0><tr><td>Copyright © 2002 <a
