froglogic Releases Tq 2.0, the Tcl/Tk Qt Integration Framework

Hamburg, Germany – 2005-06-08 froglogic GmbH today released Tq 2.0, the framework to integrate Tcl/Tk and Qt.

Tq enables integrating the Tcl/Tk and Qt toolkits in a single application. This way it is possible to incrementally port Tcl/Tk applications to Qt while still keeping Tk components running in the new application. Besides event loop integration, Tq ensures modal dialog behavior across toolkit boundaries, adjusts color schemes and allows embedding Tk widgets into Qt widgets.

The following new features have been added to Tq 2.0:

  • Via the new TqCargo class it is now also possible to embed Qt widgets into Tk windows. This opens up completely new possibilities such as using popular Qt components in existing Tk applications.
  • Via the TqHook() it is now possible to integrate a Qt event loop into a Tk application without changing Tk_Main(). This is necessary when developers don’t have access to the complete source code of the Tk application.
  • An improved TqConsole provides a complete interactive Tcl/Tk console replacement for wish.


Tq customers and evaluators can now find Tq 2.0 packages in their download area. For more information about Tq or to obtain an evaluation version of Tq, visit or contact us at

Harri Porten is of German and Finnish descent and grew up in Germany and Thailand. After high school he studied at the Technical University of Hamburg-Harburg in Germany, and at the University of Waterloo in Canada; he graduated with a diploma in Mechanical Engineering. Harri started programming on an Apple II, and soon turned his hobby into a source of income, providing maintenance and consultancy services to local businesses. After discovering Linux, Harri joined the "KDE" project, where he eventually implemented a JavaScript interpreter – this interpreter was adopted for use in KDE's web browser "Konqueror", and is now also used by Apple in its Safari browser, and served as the starting point for WebKit's JavaScript interpreter. Harri began working as a software engineer at Trolltech AS in Oslo in the summer of 2000. During the next three years he oversaw the portability of the Qt GUI toolkit to a wide variety of different compilers and operating systems, including HP-UX and AIX. In addition, he implemented Qt's original SVG support, and was involved in Trolltech's quality assurance process. Harri was also a member of the Qt Script for Applications (QSA) team. Harri co-founded froglogic in 2003.
