I'm trying to implement a simulation of a system that displays HTML
information with hot links. However, the tricky 'extra' is the fact
that each single word/phrase hot link is actually treated as two
halves with a click on the first half of a hot word taking you
backwards and a click on the second half taking you forwards!
The problem I'm having is that I can't easily work out which half of
a hot word the user has clicked into. I can get the ClickText() for
the whole word and the ClickChunk() tells me the chars of the whole
word. The ClickLoc() gives me a coordinate pair, but I can't see how
to relate this to the characters in the hot word. What makes life
difficult is the fact that the HTML has variable size text as well as
some mixed plain and bold text.
I tried splitting a single word into two separate words and making
them individual hot words, but came up with the problem of having to
make them look like a single word whilst behaving as if there's some
character separating them.
Anyone got any good ideas for this?
Also, once I've detected a hot word, I need to jump to another line
within the field. How do I reliably reposition a field with variable
height lines on a line boundary? I tried adding the textHeight of
all lines from top to required line, multiplying the total by 4/3 and
then setting the vScroll accordingly. Unfortunately, this isn't
reliable, especially if there is a blank line as this returns an
empty textHeight.
Any ideas for this?
