I am trying to understand how to manage formatted text in fields and I am
missing something. I have field “in” that contains a long page of formatted
text that ultimately will be hidden. I have another field “out” where I am
trying to page the data from field “in” like pages of a book (no scrolling)
I thought I would loop thru the lines of field “in” from a starting_line and
increase the ending_line until the formattedheight of lines stating_line to
ending_line of field “in” > the height of field “out”. Then back off the
ending_line by 1. I thought this would work, but it seems that I am not
comparing the right things.
The height of field “out” seems to be less than what can actually be seen in
field “in”. The algorithm tells me that I can only fit 14 lines of data into
field out, where i really can fit 24.
So, what am I missing? I must not be comparing the correct things. BTW, I
have the fixed line height turned off for both fields.
Seperate from my comparison issue, Is there a better technique to accomplish
this paging operation? Ultimately, I need to page both forward and backwards.
I appreciate any guidance that you all can provide.
Regards,
Mike
on loadpage
put current_line + 1 into startline
put startline into endline
put the number of lines in fld "in" into lastline
put the height of fld "out" into max_height
repeat until endline > lastline
put the formattedheight of line startline to endline of fld "in" into
new_height
if new_height >= max_height then
put endline - 1 into endline
put endline - 1 into lastline
else
add 1 to endline
end if
end repeat
set the htmlText of fld "out" to the HtmlText of line startline to endline
of fld "in"
put endline into currentline
end loadpage
