Subject: bug#18249: 24.3; expected a button click, text pasted into button label instead
Date: Mon, 11 Aug 2014 23:59:37 +0200 [thread overview]
Message-ID: <84k36eofg6.fsf@gmail.com> (raw)
Hello,
I found some odd behaviour while clicking with <mouse-2>
over a button. I can't say if it's exactly a bug, but I believe
it's unexpected and unwanted behaviour for the user. Here's
a recipe to replicate it.
1) start emacs -Q
2) clear buffer with C-x h C-w
3) type or paste the following five lines of text (line 3 is
empty on purpose):
;---------- line1: start
(insert-button "[ciao]" 'action (lambda (x) (message "ciao!"))) ; line 2
; line 4: pastethis
; --------- line 5: end
4) put the text cursor at line 3, type C-x C-e so that
the "[ciao]" button will be created in line 3
5) select the word "pastethis" with the mouse, by dragging with
mouse-1 button from first to last letter of the word
6a) put the mouse cursor over the [ciao] button and click there with
mouse-2 (center button). Result: you should see that the message
"ciao!" appears at the bottom line; this is correct and expected
behaviour
6b) move the mouse cursor over the letter "i" of the text "line 4:",
click mouse-2 and hold it pressed; continue dragging and move the
mouse cursor over the [ciao] button, then release mouse-2.
Result: you should see that the word "pastethis" has been pasted
into the button label, so that it looks similar to
[ciapastethiso]; this is unexpected behaviour.
May I please ask if the result 6b) is reproducible for you too.
I believe 6b) is odd/buggy because typically the user wants
to do action 6a) but accidentally drags the mouse by a few pixel,
thus actually performing action 6b). Please let me know if this
opinion seems wrong/flawed to you.
If the above makes sense for you too, then a possible correction
could be: if a <drag-mouse-2> event ends on a pushable button,
then Emacs should always perform the button action, not a text
paste like it does now.
Thanks for your attention and patience in reading this,
kindest regards.
