<h2>Detailed Description</h2>
<p>The QSourceLocation class identifies a location in a resource by URI, line, and column.</p>
<p>QSourceLocation is a simple value based class that has three properties, <a href="qsourcelocation.html#uri">uri</a>(), <a href="qsourcelocation.html#line">line</a>(), and <a href="qsourcelocation.html#column">column</a>(), that, taken together, identify a certain point in a resource, e.g., a file or an in-memory document.</p>
<p><a href="qsourcelocation.html#line">line</a>() and <a href="qsourcelocation.html#column">column</a>() refer to character counts (not byte counts), and they both start from 1, as opposed to 0.</p>

<h3 class="fn"><a name="column"></a><a href="qtglobal.html#qint64-typedef">qint64</a> QSourceLocation::column () const</h3>
<p>Returns the current column number. The column number refers to the count of characters, not bytes. The first column is column 1, not 0. The default value is -1, indicating the column number is unknown.</p>
<p>See also <a href="qsourcelocation.html#setColumn">setColumn</a>().</p>
<a name="//apple_ref/cpp/instm/QSourceLocation/isNull"></a>
<h3 class="fn"><a name="isNull"></a>bool QSourceLocation::isNull () const</h3>
<p>Returns <tt>true</tt> if this <a href="qsourcelocation.html">QSourceLocation</a> doesn't identify anything.</p>
<p>For a default constructed <a href="qsourcelocation.html">QSourceLocation</a>, this function returns <tt>true</tt>. The same applies for any other <a href="qsourcelocation.html">QSourceLocation</a> whose <a href="qsourcelocation.html#uri">uri</a>() is invalid.</p>
<a name="//apple_ref/cpp/instm/QSourceLocation/line"></a>
<h3 class="fn"><a name="line"></a><a href="qtglobal.html#qint64-typedef">qint64</a> QSourceLocation::line () const</h3>
<p>Returns the current line number. The first line number is 1, not 0. The default value is -1, indicating the line number is unknown.</p>
<p>See also <a href="qsourcelocation.html#setLine">setLine</a>().</p>
<a name="//apple_ref/cpp/instm/QSourceLocation/setColumn"></a>
<h3 class="fn"><a name="setColumn"></a>void QSourceLocation::setColumn ( <a href="qtglobal.html#qint64-typedef">qint64</a> <i>newColumn</i> )</h3>
<p>Sets the column number to <i>newColumn</i>. 0 is an invalid column number. The first column number is 1.</p>

<a name="//apple_ref/cpp/instm/QSourceLocation/setLine"></a>
<h3 class="fn"><a name="setLine"></a>void QSourceLocation::setLine ( <a href="qtglobal.html#qint64-typedef">qint64</a> <i>newLine</i> )</h3>
<p>Sets the line number to <i>newLine</i>. 0 is an invalid line number. The first line number is 1.</p>

<a name="//apple_ref/cpp/instm/QSourceLocation/uri"></a>
<h3 class="fn"><a name="uri"></a><a href="qurl.html">QUrl</a> QSourceLocation::uri () const</h3>
<p>Returns the resource that this <a href="qsourcelocation.html">QSourceLocation</a> refers to. For example, the resource could be a file in the local file system, if the URI scheme is <tt>file</tt>.</p>

<p>Assigns this <a href="qsourcelocation.html">QSourceLocation</a> instance to <i>other</i>.</p>
<a name="//apple_ref/cpp/instm/QSourceLocation/operator=="></a>
<h3 class="fn"><a name="operator-eq-eq"></a>bool QSourceLocation::operator== ( const QSourceLocation & <i>other</i> ) const</h3>
<p>Returns true if this <a href="qsourcelocation.html">QSourceLocation</a> is identical to <i>other</i>.</p>
<p>Two <a href="qsourcelocation.html">QSourceLocation</a> instances are equal if their <a href="qsourcelocation.html#uri">uri</a>(), <a href="qsourcelocation.html#line">line</a>() and <a href="qsourcelocation.html#column">column</a>() are equal.</p>
<p><a href="qsourcelocation.html">QSourceLocation</a> instances for which <a href="qsourcelocation.html#isNull">isNull</a>() returns true are considered equal.</p>
