From: ynyaaa
Subject: bug#39247: 26.3; inappropriate mouse pointer shapes
Date: Thu, 23 Jan 2020 11:25:09 +0900

In some cases, mouse pointer shapes are not appropriate.

(1)'text shape on mode-line.
   Move the mouse pointer onto the line number in the mode-line
   at the bottom of the emacs frame.
   Move the pointer to the right SPC.
   Then the pointer shape is 'text.
   (With (setq resize-mini-windows nil), this does not occur.)

(2)'text shape on header-line.
   Evaluate the form below.
   Move the mouse pointer onto the text 'YYY'.
   Move the pointer up to the blank area of the header-line.
   Then the pointer shape is 'text.

   (let ((buf (generate-new-buffer "tmp")))
     (switch-to-buffer buf)
     (setq header-line-format "xxx")
     (insert "xxxYYY"))

(3)'hourglass shape when emacs is not busy
   Move the mouse pointer onto a text area of emacs frame.
   Do not touch the mouse afterwards.
   Evaluate the form below.
   Type 'j' to insert 'j'.
   Type 'a' to make emacs busy.
   Type Alt-Tab to switch to another application.
   Type Alt-Tab again to switch back to the emacs frame.
   Type 'C-g' to stop the busy loop.
   Then the pointer shape keep 'hourglass.

   (let ((buf (generate-new-buffer "tmp"))
         (map (make-sparse-keymap)))
     (menu-bar-mode 0)
     (switch-to-buffer buf)
     (define-key map "a"
       (lambda () (interactive) (dotimes (i 1000000000))))
     (use-local-map map))

(4)shape of 'pointer property value put on another area
   Evaluate the form below.
   Move the mouse pointer onto 'yyy'.
   Move the pointer left to 'XXX' or right to 'ZZZ'.
   Then the pointer shape keep 'hdrag.

   (let ((buf (generate-new-buffer "tmp")))
     (switch-to-buffer buf)
     (insert (propertize "XXX" 'mouse-face 'region)
             (propertize "yyy" 'mouse-face 'region 'pointer 'hdrag)
             (propertize "ZZZ" 'mouse-face 'region)))

(5)'text shape on the blank area in the echo area.
   Show any message in the echo area. For example, type 'C-g'.
   Move the mouse pointer onto the blank area of the echo area.
   Then the pointer shape is 'text.
   Even after the message is cleared with some input such as 'C-f',
   the pointer shape on the echo area may remain 'text.

(6)'text shape on an image map area with empty PLIST
   The form below inserts a image with four circles.
   Spec for a red circle has empty PLIST.
   The mouse poiter shape on the red circle is 'text.

(let ((svg (progn (require 'svg) (svg-create 200 200))))
  (svg-circle svg  50  50 50 :fill-color "red")
  (svg-circle svg 150  50 50 :fill-color "green")
  (svg-circle svg  50 150 50 :fill-color "blue")
  (svg-circle svg 150 150 50 :fill-color "yellow")
    svg :map '(((circle . ((50 . 50) . 50)) red-area nil)
               ((circle . ((150 . 50) . 50)) green-area (dummy "green"))
               ((circle . ((50 . 150) . 50)) blue-area (help-echo "blue"))
               ((circle . ((150 . 150) . 50)) yellow-area
                (help-echo "yellow" pointer hdrag)))))
   (1- (point)) (point) 'keymap
   (let ((map (make-sparse-keymap)))
     (dolist (color '("red" "green" "blue" "yellow"))
       (let ((area (intern (format "%s-area" color))))
         (define-key map (vector area 'mouse-1)
           `(lambda (ev) (interactive "e")
              (let ((tmp (event-end ev)))
                (message "%S" (posn-area tmp)))))))
