What is Qt? I think it is a GUI library - anyone have more info? What makes it a good match for Tcl - or at least, of interest (other than academic)?
NEM - Qt is the library used by KDE applications isn't it? CL answers: yes and no. KDE itself is constructed with Qt; that's true. It's possible to launch an application made with any X toolkit from KDE, though, so what people think are "KDE applications" might only be X applications.
Mike Tuxford points out: Qt, while currently 'free' to use is privately copyrighted IP and is subject to change. There have been previous concerns that the Qt license could change and in todays dog-eat-dog market one can never know when the company might be bought out and the license changed. A GPL'd alternative would be GTK which is used by the Gnome X environment.
George Petasis observes that "Under Qt, the programmer can control only a few aspects of how the widget looks. The vast majority of the appearance of the widget is determined by the theme." Also surprising, from a Tk programmer's perspective, is that a button can't be simultaneously decorated with an image and a label.
George has prototyped a TkQt at [L1 ]. An alternate URL for the same file is [L2 ].
