***Description*** 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, which also includes the [Tcl] wrappers for calling the gl* methods. 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 http://chiselapp.com/user/wiede/repository/ntk/index%|%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 available widgets, 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). ---- [apw] 2014-02-09: First Tcl command (clearbuffer) implemented and running for [Android] [APWTCL (Java)] based on OpenGL ES 2.0. This includes the base code for implementing a package named [TclGles20] (about 700 LOC in [Java]). The TclGles20 commands are the base for [ttk] like widgets implemented in [itcl-ng] based on [OpenGL ES] 2.0. ---- [apw] 2014-02-20: Some more Tcl commands (drawline, drawtriangle, filltriangle, drawrectangle, fillrectangle) implemented and running (mostly) for [Android] [APWTCL (Java)] based on OpenGL ES 2.0. See table in [TclGles20] (now about 2500 LOC in [Java]). <> Package | GUI
