<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>
