Perhaps I should add that if you use C-g (keyboard-quit) or close the
dialog box using window's close button that causes a quit signal and the
function nor its callers won't return. Here's a new version which will
catch the quit signal and, if that happens, return nil:
(defun my-dialog (title item-alist)
(condition-case nil
(if (display-popup-menus-p)
(x-popup-dialog t (cons title item-alist) nil)
(let ((tmm-completion-prompt (concat title "\n\n")))
(tmm-prompt (list "" (cons "" item-alist)))))
(quit nil)))
