How to increase the textsize of HTMLtext proportional?

[Tiemo Hollmann TB]

Hello,

I give the user the option to change the textsize of all fields. No problem
so far by just changing the textsize and adjusting the field size. Now I
have a field with different textsizes in one field. Like bold and bigger
headlines, and standard text, etc.

How would you change the textsize of such a text by keeping the size
relation of the different chunks of text? Should I look up the HTMLtext and
manipulate every "font size attribute" - or is there a more straight forward
approach, I don't see?

Thanks

Tiemo

I asked this question here a few years back, and there were many good 
solutions presented, with Malte's being the fastest IIRC:

You might look at "styledtext" which returns an array describing all the
text variations in the field. Very handy.

I was interested in this discussion so I pasted the source of the link below 
into a field and copied the code into a button.   Be careful.   This code does 
not account for the case where the text string "size=" is in the content of the 
html.  In this case the "size=" string is in the  block.

[Michael Doub]

I think this solves the problem.   You want to make sure that there is a ">" 
but not if it is found after a "<".

on mouseUp
   put the htmlText of fld 1 into theHtml
   replace "size=""e with "size="&numtoChar(1500) in theHTML
   set the itemdel to numToChar(1500)
   if the number of items of theHTML<>1 then
  put 0 into itemCount
  repeat for each item theItem in theHTML
 add 1 to itemCount
 if itemCount=1 then
put theItem into newHTML
next repeat
 end if
 put 1 into counter
 put offset (">", theItem) into tLeft
 put offset ("<" , theItem) into tRight
 if tLeft <> 0 then -- found it
if tRight <> 0 and tRight > tLeft then-- found "<" and after ">" 
which is ok
   repeat forever
  add 1 to counter
  if char counter of theItem=quote then exit repeat
   end repeat
   put char 1 to counter-1 of theItem into theSize
   put theSize + 1 into theSize
   put theSize into char 1 to counter-1 of theItem
end if
 end if
 put quote&theItem after newHTML
  end repeat
  set the htmlText of fld "test" to newHTML
   end if
   set the textSize of fld "test" to \
 the effective textSize of fld "test"+1
end mouseUp

A bit more suitable for easy reuse.


on textdown
BumpText the long id of field "test", -1
end textdown

on textup
BumpText the long id of field "test", 1
end textup


on BumpText theObject theDirection
if theDirection is not among the lines of "1" & return & "-1" then throw 
"Need 1 or -1 for theDirection"
put the htmlText of fld 1 into theHtml
replace "size=""e with "size="&numtoChar(1500) in theHTML
set the itemdel to numToChar(1500)
if the number of items of theHTML<>1 then
   put 0 into itemCount
   repeat for each item theItem in theHTML
  add 1 to itemCount
  if itemCount=1 then
 put theItem into newHTML
 next repeat
  end if
  put 1 into counter
  put offset (">", theItem) into tClose
  put offset ("<" , theItem) into tOpen
  if tClose <> 0 then -- found it
 if tOpen <> 0 and tOpen > tClose then-- found "<" and after ">" 
whis is ok
repeat forever
   add 1 to counter
   if char counter of theItem=quote then exit repeat
end repeat
put char 1 to counter-1 of theItem into theSize
put theSize + theDirection into theSize
put theSize into char 1 to counter-1 of theItem
 end if
  end if
  put quote&theItem after newHTML
   end repeat
   set the htmlText of theObject to newHTML
end if
set the textSize of theObject to \
  the effective textSize of theObject + theDirection
end BumpText
