Following this blog post, I am interested in using popup.el for my own purposes. In the post, he mentions to add a scroll bar with the :scroll-bar argument. If I include the :scroll-bar t option in popup-tip a scroll bar is displayed, but I couldn't find any way to actually use it. Is this functionality just not implemented? If it is, could you provide an example?
(defun hlwm/object-tree ()
"Show the current hlwm object tree in a buffer."
(let* ((shell-command-switch "-c")
(object-tree-string
(shell-command-to-string "herbstclient object_tree")))
(popup-tip object-tree-string
:point (point)
:around t
:height 30
:scroll-bar t
:margin t)))
