Are you targeting multiple operating systems with your rich-client application?  Are your existing approaches too slow or costly?  If portability is important to your project, then Qt - the standard application framework for high-performance, cross-platform development - could be an ideal way to target your platforms of choice without trading off on performance, innovation, time to market and cost.

Deliver Innovative Applications Faster

• Rely on Qt's comprehensive libraries for low-level infrastructure on all platforms - available for both C++ and Java programmers
  
• Use an intuitive API to develop advanced rich client applications; quick to learn, easy to use and produces highly readable code
• Focus your time on creating core value, rather than building glue-code for different windowing systems and APIs
• Cut maintenance time and cost by working with a single code-base for all the platforms you target
• Deliver truly native applications on all platforms; utilize system resources and realize native performance
  

• Target a new operating system with little more than a simple recompile, getting to market faster
  

Used by Over 5,000 Companies
