From: Michael Welsh Duggan <mwd <at> md5i.com> To: 19185 <at> debbugs.gnu.org Subject: bug#19185: 25.0.50; Strangeness with mouse-1 button up events Date: Tue, 25 Nov 2014 19:52:08 -0500
emacs -Q
C-h k <click mouse-1 in the *scratch* buffer>
We get the following *Help*:
<down-mouse-1> at that spot runs the command mouse-drag-region (found
in global-map), which is an interactive compiled Lisp function in
`mouse.el'.
It is bound to <down-mouse-1>.
(mouse-drag-region START-EVENT)
Set the region to the text that the mouse is dragged over.
Highlight the drag area as you move the mouse.
This must be bound to a button-down mouse event.
In Transient Mark mode, the highlighting remains as long as the mark
remains active. Otherwise, it remains until the next input event.
----------------- up-event ----------------
<mouse-1> at that spot runs the command mouse-set-point (found in
global-map), which is an interactive compiled Lisp function in
`mouse.el'.
It is bound to <mouse-1>.
(mouse-set-point EVENT &optional PROMOTE-TO-REGION)
Move point to the position clicked on with the mouse.
This should be bound to a mouse click event type.
If PROMOTE-TO-REGION is non-nil and event is a multiple-click,
select the corresponding element around point.
[back]
Now, type C-h k and click (mouse-1) on a `mouse.el' link in the *Help*
buffer.
<down-mouse-1> (translated from <mouse-1>) at that spot runs the
command mouse-drag-region (found in global-map), which is an
interactive compiled Lisp function in `mouse.el'.
It is bound to <down-mouse-1>.
(mouse-drag-region START-EVENT)
Set the region to the text that the mouse is dragged over.
Highlight the drag area as you move the mouse.
This must be bound to a button-down mouse event.
In Transient Mark mode, the highlighting remains as long as the mark
remains active. Otherwise, it remains until the next input event.
----------------- up-event ----------------
<mouse-2> at that spot runs the command push-button (found in
button-map), which is an interactive compiled Lisp function in
`button.el'.
(push-button &optional POS USE-MOUSE-ACTION)
Perform the action specified by a button at location POS.
POS may be either a buffer position or a mouse-event. If
USE-MOUSE-ACTION is non-nil, invoke the button's mouse-action
instead of its normal action; if the button has no mouse-action,
the normal action is used instead. The action may be either a
function to call or a marker to display and is invoked using
`button-activate' (which see).
POS defaults to point, except when `push-button' is invoked
interactively as the result of a mouse-event, in which case, the
mouse event is used.
If there's no button at POS, do nothing and return nil, otherwise
return t.
[back]
Here the up-event is <mouse-2>. Why? Going further, if I am in Gnus
and click on a link in an email, I get the following:
<down-mouse-1> (translated from <mouse-1>) at that spot runs the
command widget-button-click (found in gnus-article-mode-map), which is
an interactive compiled Lisp function in `wid-edit.el'.
(widget-button-click EVENT)
Invoke the button that the mouse is pointing at.
----------------- up-event ----------------
<mouse-2> at that spot runs the command mouse-yank-primary (found in
global-map), which is an interactive compiled Lisp function in
`mouse.el'.
(mouse-yank-primary CLICK)
Insert the primary selection at the position clicked on.
Move point to the end of the inserted text, and set mark at
beginning. If `mouse-yank-at-point' is non-nil, insert at point
regardless of where you click.
[back]
This is definitely wrong. widget-button-click makes sense, but
mouse-yank-primary makes Emacs beep at me.
