Hi. I'm trying to create an edit box that only allows certain
kinds of editing, specifically adding and removing newlines. I thought
I could do this by trapping all non-control keys and eating the events,
then trapping backspace and delete and looking at the characters next to
the insertion point. However, it doesn't seem to work, because I can't
reliably use my dEditBox.InsertionPosition as an index into the Value.
I suspect this may be because the newlines are somehow being stored
as \r\n, which is two characters -- it looks like the insertion position
gets incremented by TWO (not one) if I move the cursor across a line
break. However, I can't see any way to compensate for this other than
counting the number of line breaks from the start of the text to the
insertion point, and adjusting the index by that much. Needless to say,
that seems pretty silly. Isn't there a way to get a dEditBox to tell me
what character is at (i.e., just before or just after) the insertion
point?
Thanks,
