<h2>Detailed Description</h2>
<p>The QSysInfo class provides information about the system.</p>
<ul>
<li><a href="qsysinfo.html#Sizes-enum">WordSize</a> specifies the size of a pointer for the platform on which the application is compiled.</li>
<li><a href="qsysinfo.html#Endian-enum">ByteOrder</a> specifies whether the platform is big-endian or little-endian.</li>
<li><a href="qsysinfo.html#WindowsVersion-var">WindowsVersion</a> specifies the version of the Windows operating system on which the application is run (Windows only)</li>
<li><a href="qsysinfo.html#MacintoshVersion-var">MacintoshVersion</a> specifies the version of the Macintosh operating system on which the application is run (Mac only).</li>
</ul>
<p>Some constants are defined only on certain platforms. You can use the preprocessor symbols <a href="qtglobal.html#Q_WS_WIN">Q_WS_WIN</a> and <a href="qtglobal.html#Q_WS_MAC">Q_WS_MAC</a> to test that the application is compiled under Windows or Mac.</p>
