8 years ago @jkordani the top-level entries aren't supposed to be activated I think; I pushed a fix to #41; however that will only prevent the error, not that clicking on the entries doesn't do anything.
after quickloading :cl-cffi-gtk-demo-gtk and evaluating gtk-demo:main, the gtk+ lisp code demos window opens, with 2 panes. On the left is all the text for the different examples, but the right window does not update when a new text on the left is selected. different backtraces are produced when the different entries are doubleclicked, the one for button widgets is shown below.
The value NIL is not of the expected type STRING. [Condition of type TYPE-ERROR]
