Qt for OS/2 is a native version of the Qt Toolkit for the OS/2 Operating System. The current version of Qt for OS/2 is 3.3.1. This version has a release candidate status meaning that it is not a complete 3.3.1 version comparing to other platforms -- selected features are still in progress. However, even without these features, this version can be used to create powerful crossplatform applications that run as native Presentation Manager applications under OS/2 and eComStation.
