Features available from [Tk]. This page is a companion piece to the [Tcl Portable Runtime Library]. [XLEL]: the Xlib emulation layer. If you need to draw graphics cross-platform, this is for you. (Note: there are other approaches to this also, but they are not in the core: [TkGS], [NexTK]) [DKF]: Note that the emulation layer also hides virtually all the differences between different platforms relating to [event] handling. The only tricky bit is that some platforms simply don't deliver all the events that real [X%|%X11%|%] produces. <> Tk Library
