Oslo, Norway — (press release excerpt) — Trolltech today announced the release of Qt 3.1. New features, notably the Motif integration, enable a gradual transition path for single platform applications to the multiplatform world of Qt.

The Qt 3.1 QMotif integration module lets developers insert Qt-based code into existing Motif applications step by step. QMotif removes the need to rewrite the entire code base at once and allows a hybrid application to run during the porting process.

ActiveQt, introduced in Qt 3.1, lets developers use the clean, simple Qt API to write ActiveX servers and controls. ActiveQt is a simple and efficient manner in which to use ActiveX technology, facilitating a better integration of Qt with the Windows environment. When migrating to Qt, developers may keep using parts of the original MFC application by integrating the ActiveX servers and controls into the new Qt application, and then gradually port them to Qt.

Qt 3.1 also enables users to implement their own Help Browser based upon Qt's own Documentation Help Engine, giving Qt users an up and running framework into which they can insert their own documentation libraries. Other Qt 3.1 benefits include easier graphical user interface (GUI) design, enhanced documentation assistance, improved multi-threading and hundreds of improvements to the existing class library.

Qt 3.1 is free of charge to open-source developers on Unix/Linux. Please contact Trolltech for information on commercial use.
