Frederic Bonnet

I am French and live in Rennes, France. I have been using Tcl/Tk since 1993. A number of annotations in the Wiki use the shortcut FB.

I have written some extensions:

My current interests include:

  • TkGS: the Tk Graphics System. An effort to replace the current Xlib Emulation Layer (XLEL) with a cross-platform, device-independent layer. Goals: better performances on non-X platforms, greater modularity (device drivers), printing support...
  • Themes support. I wrote TIP #48 , which served as a basis for Joe English's work on Tile.
