Spotting a hyperlink?

[richmond62]

Let's suppose I have a text file that contains the word 'potatoes', and I read it into a textField "BigGUFF". . .

Now for every incidence of the word 'potatoes' I want to make the word 'potatoes' blue, and hyperlink it to another field called "TATTIES" so that when I click on it the content of the field "TATTIES" is loaded into the field "BigGUFF" . . .

The styling handler:

Code: Select all

command processLinks pFieldToProcess,pWordToLinkStyle
   set the textStyle of word 1 to -1 of field pFieldToProcess to empty
   put field pFieldToProcess into tText
   
   lock screen
   put 0 into tStartSearchAt
   set the wholeMatches to true
   
   repeat
      put tokenOffset(pWordToLinkStyle, tText, tStartSearchAt) into tWordNum
      
      if tWordNum = 0 then
         exit repeat
      end if
      
      add tStartSearchAt to tWordNum
      set the textStyle of word tWordNum of field pFieldToProcess to link
      put tWordNum into tStartSearchAt
   end repeat
   
   unlock screen
end processLinks

Call it with e.g.

Code: Select all

on mouseUp
   processLinks "BigGUFF","potatoes"
end mouseUp

In the field script:

Code: Select all

on linkClicked pLink
   if pLink is among the words of the text of me then 
      answer pLink ## Insert whatever you really want it to do
   end if
end linkClicked

See the linkText property, and the linkClicked message to handle it.
