NODGUI

NODGUI

“No Drama GUI”

Common Lisp bindings for the Tk GUI toolkit.

important note:

Version 0.4.0 broke the user API, see here for more information about how your code is affected and how to fix it.

Features

• custom themes
• more widgets:
  • history-entry
  • autocomplete
  • expanded “text” widget
  • date picker
  • treelist
  • tooltip
  • searchable listbox
  • password entry
  • openGL frame
  • …
• tklib-derived widgets:
  • calendar
  • notify-window (a bit buggy, unfortunately)
  • plots and charts: dot-plot, bar-chart…
• asynchronous main event loop
• and more

Themes

nodgui supports loading custom ttk themes and ships the “yaru” theme from the ttkthemes collection.

To use a built-in theme other than the “default” one, do:

(with-nodgui (:theme "yaru")
  (code here))

or use (setf *default-theme* "yaru").

You can see how they look with the demos:

CL-USER> (nodgui.demo:demo :theme "yaru")

You can load any .tcl file describing a theme:

(nodgui:eval-tcl-file "path/to/another/theme.tcl")
(nodgui:use-theme "theme")

See also *themes-directory*.

This currently doesn’t work with a few themes using SVG images, but it might be fixed with the release of an upcoming Tcl/Tk version.
