Re: here's a challenge

You will need to track the mouseMove message in your story field. This 
gives you the coordinates of the mouse which you can use to position 
the box (a graphic or as Dar suggested a text style). Here is a script 
I use to make sure that any scroll results in an exact line i.e. the 
top of the field shows a complete line, rather than a partial line. It 
might give you an idea on how to set the text the way you want it.

-- fix scroll to an exact line
  put (the vScroll of me div the textHeight of me) + 1 into tLineNum
  set the vScroll of me to (tLineNum-1) * the textHeight of me
Cheers,
Sarah

Well, I think it’s a challenge anyway.

I have a field with text from a story.? It’s just basic text split 
into one or more paragraphs.? I need to come up with a way to create 
what we call a reading guide, which would basically consist of a 
rectangular box that follows the mouse pointer up and down will inside 
of the text field.? The trick is that the box must “snap” into place 
so to speak, so that the current line of text is vertically centered 
within the box.? Students will be reading the text and the box cannot 
wander if the mouse pointer is not exactly on the line of text.? I am 
using fixedLineHeight for the text field, and I think that will come 
into play somewhere (the distance to move the box up and down?).? What 
I’m not sure of is which messages I need to handle to create this kind 
of behavior.

?

Does anyone have any ideas?? Have I even made sense?? I can try again 
to explain it if necessary.

Thanks,
