I am rewriting the "ss" function in HC. Because it is there.
Whereas this works fine (in a button script):
on mouseUp
set cursor to plus
repeat until the optionKey is down
if the mouseClick then put the mouseLoc
end repeat
end mouseUp
I cannot get this to work at all:
on mouseUp
set cursor to plus
repeat until the optionKey is down
if the mouseClick then put the mouseControl
end repeat
end mouseUp
Only changed one word.
I can get mouseLocs at each click all around the stack. I can only get the
mouseControl for the object that contains the script itself. Something about the
mouseControl?
From the docs: "If the mouse button is down, the mouseControl function
returns the control that was clicked, even if the mouse has moved to
another control."
Since "the mouseclick" causes a mousedown, mouseWithin, mouseUp
sequence, and since your repeat loop is very short and tight, the
mousecontrol may be triggering on the original mousedown only. I'm
guessing though.
A better method might be to use a flag and the mousemove message:
In a button:
on mouseup
send "getmousecontrol" to this cd in 1
end mouseup
In the card or stack:
local flag
on getmousecontrol
put true into flag
end getmousecontrol
on mousemove x,y
if the optionkey is down then put false into flag
if flag then put the mousecontrol
end mousemove
There are some other reasons not to poll the mouse inside a repeat loop.
One reason is that the right values aren't always returned, because the
condition of the mouse is only checked at the exact moment the line of
script is running. In long loops, a mouseclick may not trigger at all if
the mouse is clicked while a different command inside the loop is running.
