From: Visuwesh <visuweshm <at> gmail.com> To: 56779 <at> debbugs.gnu.org Subject: bug#56779: 29.0.50; [wishlist] Function to check if a mouse-button is pressed Date: Tue, 26 Jul 2022 14:28:46 +0530
Currently, to know if a mouse button is being pressed, one has to keep
track of state by cleverly utilising [down-mouse-N] and [mouse-N] events
(see [1]). It is certainly no easy task, it would be really nice if
Emacs had the equivalent of `xinput --query-state <mouse-id>' [2]
(the implementation of which can be found in state.c in xinput's
source).
The reason I ask this is because I would really like to have mouse
chording in Emacs but currently it is too hard to implement it (BTW,
mouse-copy.el talks about mouse-chording).
1. https://github.com/akrito/acme-mouse
2. All you need to do is,
% xinput --query-state <mouse-id> |sed -n 's/[ \t]\+button\[1\]=//p'
to get the state of mouse-1.
