Also the sizeList returned by the getHSizes function should be sorted
numeric descending for enlarging textsize and ascending for reducing
textsize, lest not to lose some initial size differences of 1
greetings,
Wouter
on changeTextSize inc
-- make the tags that will set text to the effective textSize in
force
put "<font size=" & quote & the effective textSize of fld 1 &
quote & ">" into openTag
put "</font>" into closeTag
-- get the html
put the htmltext of fld 1 into ttext
--this next block sets size tags for all the unsized text
replace "</font>" with "</font>" & openTag in ttext
replace "<font size=" with closeTag & "<font size=" in ttext
replace closeTag & closeTag with closeTag in ttext
--ugly, i know, but I could'nt see a better way
put openTag after char 3 of ttext
-- puts openTag after the intial <p> tag
--now get all the size values from the size tags
--via the getHSizes function
put getHSizes(ttext) into sizeList
if inc < 0 then sort sizeList numeric ascending #####
else sort sizeList numeric descending #####
if sizeList is not empty then
if "8" is among the lines of sizeList and inc > 0 then
beep
exit to top
end if
repeat for each line L in sizeList
put quote & L & quote into pSize
put quote & L+inc & quote into nSize
replace "<font size=" & pSize with "<font size=" & nSize in
ttext
end repeat
end if
set the htmltext of fld 1 to ttext
end changeTextSize
function getHSizes tt
put empty into sizeList
-- turn each tag into an item
replace "<" with numToChar(28) in tt
replace ">" with numToChar(28) in tt
set the itemDelimiter to numToChar(28)
repeat for each item i in tt
if "font size=" is in i then
--if the item is a font size tag then
--get the value inside the quotes ie font size="14"
put offset(quote,i) +1 into startChar
put offset(quote,i,startchar) into endChar
put char startChar to (startChar + endChar -1) of i into fSize
if fSize is not among the lines of sizeList then put fSize &
cr after sizeList
end if
end repeat
return char 1 to -2 of sizeList
end getHSizes
