Can you share the workaround?
So, I have a custom data grid with 2000 rows, each row is a sub-group
with 1 checkbox and 6 fields. Each row can have a different height
according to the HTMLtext in the fields (dontwrap is false, so the
HTMLtext can look like more than 1 line).
On mousemove, when the mousetext corresponds to an entry in an array, a
custom tooltip is displayed with specific content, and positioned at the
top right corner of the chunk, otherwise the tooltip is hidden.
on mousemove
get the mousetext
if the keys of Tarray[it] is not empty then
lock screen
put the mousechunk into c
put last word of c into f
put top of fld f into ft
put the mouseloc into m
put the textHeight of fld f into th
put the margins of fld f into mg
put trunc((item 2 of m - (ft + mg)) / th) into z
put (4 + ft + (th * z)) into b
put the HTMLtext of fld f into temp
if z = 0 then -- only 1 line
put "1" into word 2 of c
put ("put $" & (the value of c) & "$ into fld " & f)
into z
replace "$" with quote in z
do z
put the formattedwidth of fld f into x
put (left of fld f + x - 2) into l
else -- multiple lines
put (item 1 of m) - (left of fld f) - mg into xx
put c into d
put 1 into word 2 of d
put the value of d into v
put number of words of v into n
repeat with i = n down to 1
put word i to n of v into fld f
put (the formattedwidth of fld f) - (mg * 2)
into w
if w >= xx then
put w + (left of fld f) + (mg * 2) into
l
exit repeat
end if
end repeat
end if
-- displays the tooltip
set bottom of grp st to b
set left of grp st to l
show grp st
set the HTMLtext of fld f to temp
else
-- hides the tooltip
hide grp st
end if
end mousemove
This runs fast on an old iMac Intel from 2012 with LC 9.6.3.
