<hr><a name="details"></a><h2>Detailed Description</h2>
The TQTableSelection class provides access to a selected area in a
<a href="ntqtable.html">TQTable</a>.
<p>
<p> The selection is a rectangular set of cells in a TQTable. One of
the rectangle's cells is called the anchor cell; this is the cell
that was selected first. The <a href="#init">init</a>() function sets the anchor and
the selection rectangle to exactly this cell; the <a href="#expandTo">expandTo</a>()
function expands the selection rectangle to include additional
cells.
<p> There are various access functions to find out about the area:
<a href="#anchorRow">anchorRow</a>() and <a href="#anchorCol">anchorCol</a>() return the anchor's position;
<a href="#leftCol">leftCol</a>(), <a href="#rightCol">rightCol</a>(), <a href="#topRow">topRow</a>() and <a href="#bottomRow">bottomRow</a>() return the
rectangle's four edges. All four are part of the selection.
<p> A newly created TQTableSelection is inactive -- <a href="#isActive">isActive</a>() returns
FALSE. You must use init() and expandTo() to activate it.
<p> <p>See also <a href="ntqtable.html">TQTable</a>, <a href="ntqtable.html#addSelection">TQTable::addSelection</a>(), <a href="ntqtable.html#selection">TQTable::selection</a>(), <a href="ntqtable.html#selectCells">TQTable::selectCells</a>(), <a href="ntqtable.html#selectRow">TQTable::selectRow</a>(), <a href="ntqtable.html#selectColumn">TQTable::selectColumn</a>(), and <a href="advanced.html">Advanced Widgets</a>.
<hr><h2>Member Function Documentation</h2>
<h3 class=fn><a name="TQTableSelection"></a>TQTableSelection::TQTableSelection ()
</h3>
Creates an inactive selection. Use <a href="#init">init</a>() and <a href="#expandTo">expandTo</a>() to
activate it.
<h3 class=fn><a name="TQTableSelection-2"></a>TQTableSelection::TQTableSelection ( int start_row, int start_col, int end_row, int end_col )
</h3>
Creates an active selection, starting at <em>start_row</em> and <em>start_col</em>, ending at <em>end_row</em> and <em>end_col</em>.
<h3 class=fn>int <a name="anchorCol"></a>TQTableSelection::anchorCol () const
</h3>
<p> Returns the anchor column of the selection.
<p> <p>See also <a href="#anchorRow">anchorRow</a>() and <a href="#expandTo">expandTo</a>().
<h3 class=fn>int <a name="anchorRow"></a>TQTableSelection::anchorRow () const
</h3>
<p> Returns the anchor row of the selection.
<p> <p>See also <a href="#anchorCol">anchorCol</a>() and <a href="#expandTo">expandTo</a>().
<h3 class=fn>int <a name="bottomRow"></a>TQTableSelection::bottomRow () const
</h3>
<p> Returns the bottom row of the selection.
<p> <p>See also <a href="#topRow">topRow</a>(), <a href="#leftCol">leftCol</a>(), and <a href="#rightCol">rightCol</a>().
<h3 class=fn>void <a name="expandTo"></a>TQTableSelection::expandTo ( int row, int col )
</h3>
Expands the selection to include cell <em>row</em>, <em>col</em>. The new
selection rectangle is the bounding rectangle of <em>row</em>, <em>col</em>
and the previous selection rectangle. After calling this function
the selection is active.
<p> If you haven't called <a href="#init">init</a>(), this function does nothing.
<p> <p>See also <a href="#init">init</a>() and <a href="#isActive">isActive</a>().
<h3 class=fn>void <a name="init"></a>TQTableSelection::init ( int row, int col )
</h3>
Sets the selection anchor to cell <em>row</em>, <em>col</em> and the selection
to only contain this cell. The selection is not active until
<a href="#expandTo">expandTo</a>() is called.
<p> To extend the selection to include additional cells, call
expandTo().
<p> <p>See also <a href="#isActive">isActive</a>().
<h3 class=fn>bool <a name="isActive"></a>TQTableSelection::isActive () const
</h3>
<p> Returns whether the selection is active or not. A selection is
active after <a href="#init">init</a>() <em>and</em> <a href="#expandTo">expandTo</a>() have been called.
<h3 class=fn>bool <a name="isEmpty"></a>TQTableSelection::isEmpty () const
</h3>
<p> Returns whether the selection is empty or not.
<p> <p>See also <a href="#numRows">numRows</a>() and <a href="#numCols">numCols</a>().
<h3 class=fn>int <a name="leftCol"></a>TQTableSelection::leftCol () const
</h3>
<p> Returns the left column of the selection.
<p> <p>See also <a href="#topRow">topRow</a>(), <a href="#bottomRow">bottomRow</a>(), and <a href="#rightCol">rightCol</a>().
<h3 class=fn>int <a name="numCols"></a>TQTableSelection::numCols () const
</h3>
Returns the number of columns in the selection.
<p> <p>See also <a href="#numRows">numRows</a>().
<h3 class=fn>int <a name="numRows"></a>TQTableSelection::numRows () const
</h3>
<p> Returns the number of rows in the selection.
<p> <p>See also <a href="#numCols">numCols</a>().
<h3 class=fn>bool <a name="operator!-eq"></a>TQTableSelection::operator!= ( const <a href="qtableselection.html">TQTableSelection</a> & s ) const
</h3>
<p> Returns TRUE if <em>s</em> does not include the same cells as the
selection; otherwise returns FALSE.
<h3 class=fn>bool <a name="operator-eq-eq"></a>TQTableSelection::operator== ( const <a href="qtableselection.html">TQTableSelection</a> & s ) const
</h3>
Returns TRUE if <em>s</em> includes the same cells as the selection;
otherwise returns FALSE.
<h3 class=fn>int <a name="rightCol"></a>TQTableSelection::rightCol () const
</h3>
<p> Returns the right column of the selection.
<p> <p>See also <a href="#topRow">topRow</a>(), <a href="#bottomRow">bottomRow</a>(), and <a href="#leftCol">leftCol</a>().
<h3 class=fn>int <a name="topRow"></a>TQTableSelection::topRow () const
</h3>
<p> Returns the top row of the selection.
<p> <p>See also <a href="#bottomRow">bottomRow</a>(), <a href="#leftCol">leftCol</a>(), and <a href="#rightCol">rightCol</a>().
