使用 stumpwm,我无法使用小键盘在评估窗口中输入数字(NumLock 已打开)。通过破解 input.lisp,我发现了以下结果:
#'read-key-and-selection 将为主键盘和小键盘返回不同的值。
1 2 3 4 5 6 7 8 9
primary pad (10 . 16) (11 . 16) (12 . 16) (13 . 16) (14 . 16) (15 . 16) (16 . 16) (17 . 16) (18 . 16)
numpad (87 . 16) (88 . 16) (89 . 16) (83 . 16) (84 . 16) (85 . 16) (79 . 16) (80 . 16) (81 . 16)
它会导致 #'process-input 将小键盘输入视为 :error 。
(defun read-key-or-selection ()
(loop for ev = (xlib:process-event *display* :handler #'read-key-or-selection-handle-event :timeout nil) do
(cond ((stringp ev)
(return ev))
((and (consp ev)
(eq (first ev) :key-press))
(return (cdr ev))))))
(defun read-key-or-selection-handle-event (&rest event-slots &key display event-key &allow-other-keys)
(declare (ignore display))
(case event-key
((or :key-release :key-press)
(apply 'input-handle-key-press-event event-slots))
(:selection-notify
(apply 'input-handle-selection-event event-slots))
(t nil)))
(defun input-handle-key-press-event (&rest event-slots &key event-key root code state &allow-other-keys)
(declare (ignore event-slots root))
(list* event-key code state))
从上面的代码来看,#'xlib:process-event 似乎存在问题。但我不知道如何解决它?
请大神指点一下,谢谢!
