<p> Qt is a multiplatform 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> statements (see below).
