ntkThemed is a new implementation of Tk widgets based on OpenGL ES 2.0 and itcl-ng. For displaying texts, which are not part of OpenGL ES, a package gles2 was implemented based on FreeType fonts.
The goal behind the implementation is to have some Tk available on mobile devices like Android based or iOS based devices.
The benefit of using OpenGL ES is: it is available for Android, iOS and even as base below webgl. And OpenGL itself is a superset of OpenGL ES.
This is work in progress (WIP) and has shortly been presented on the Twentieth Annual Tcl/Tk Conference (2013) during a WIP session.
ARR This is very interesting, are there any demo files for download to get a personal impression? How can I contribute?
apw 2013-10-27: the repository for ntkThemed is still called ntk and can be found here (RS same day: domain not found) (apw 2013-10-29 should be fixed now)
I can give you write permission, if you are interested. There are a lot of missing commands for the widgets available, and the gles2 package including FreeType fonts have to be ported to Java for Android and to Objective-C for iOS, The current version is running in an OpenGL ES emulator on linux (OpenSuSe 12.3).
