* NODGUI

  /"No Drama GUI"/

  Common Lisp bindings for the Tk GUI toolkit.

** important note:

   Version ~0.4.0~ broke the user API, see
   [[https://www.autistici.org/interzona/nodgui.html#orgb574adf][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 [[https://wiki.tcl-lang.org/page/List+of+ttk+Themes][custom ttk themes]] and ships the "yaru" theme from
the [[https://ttkthemes.readthedocs.io/en/latest/themes.html#yaru][ttkthemes collection]].

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

# note: notabug.org doesn't like org source blocks. We avoid them below.

#+BEGIN_SRC txt
    (with-nodgui (:theme "yaru")
      (code here))
#+END_SRC

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.
