You thought Tcl/Tk stands for 'obsolete GUI'? You define the looks of Tk as 'prehistoric'? Or do you visualize ugly interfaces when reading this? I certainly do. Mats Bengtsson writes: "Tcl's windowing toolkit, Tk, has been 'known' to be ugly and outdated. With the 8.5 release last December the tile package, now named ttk (Themed Tk), is included in the core which brings true native widgets on Windows (yes, Vista too) and Mac." But what about Linux? Mats points at tileqt and the new tilegtk and notes: "Imagine that you can switch theme, and toolkits, on the fly without any program restart." Finally, he mentions progresses in both tkpath and support for WebKit. He concludes: "When all this comes together it will make Tk a very competitive toolkit."
