<h2>Detailed Description</h2>
 
43
<p>The QSysInfo class provides information about the system.</p>
 
44
<ul>
 
45
<li><a href="qsysinfo.html#WordSize-var">WordSize</a> specifies the size of a pointer for the platform on which the application is compiled.</li>
 
46
<li><a href="qsysinfo.html#Endian-enum">ByteOrder</a> specifies whether the platform is big-endian or little-endian.</li>
 
47
<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>
 
48
<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>
 
49
</ul>
 
50
<p>Some constants are defined only on certain platforms. You can use the preprocessor symbols <tt>Q_WS_WIN</tt> and <tt>Q_WS_MAC</tt> to test that the application is compiled under Windows or Mac.</p>
