<p>Qt is a cross-platform GUI toolkit, so almost the entire API is the same on all platforms and window systems. If you wish to use platform-specific features, and still maintain a platform-independent source tree, you should protect the platform-specific code using the appropriate <tt>#ifdef</tt> directives (see below).</p>
<p>Qt provides a few low-level global functions for fine-tuning applications on specific platforms. See <a href="exportedfunctions.html">Special-Purpose Global Functions Exported by Qt</tt></a> for details.</p>
<ul><li><a href="#qt-x11">Qt/X11</a></li>
<li><a href="#qt-windows">Qt/Windows</a></li>
<li><a href="#qt-mac-os-x">Qt/Mac OS X</a></li>
<li><a href="#qtopia-core-qt-for-embedded-linux">Qtopia Core (Qt for Embedded Linux)</a></li>
</ul>
<p>For information about which platforms are supported by Qt, see the <a href="platform-notes-platforms.html">Platform Notes</tt></a>. For information on distributing Qt applications, see Deploying Qt Applications</tt>.</p>
