Window System Specific Notes

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 #ifdef directives (see below).

Qt provides a few low-level global functions for fine-tuning applications on specific platforms. See Platform-Specific Functions for details.

For information about which platforms are supported by Qt, see the Platform and Compiler Notes. For information on distributing Qt applications, see Deploying Qt Applications.
