Hello,
I have recently built a text scrolling module for a student, one that
has all the functions provided by a normal scrolling window, but of
course allows the student to use their own graphical elements.
The issue i have is that i found it became less than elegant when
determining how many lines were not in the visible part of the text
window. In the end i had to work out an average line height so that i
could move the scroll indicator accordingly ( when using the up/down
arrows with the scroll by line function )
(member.height-member.pageheight / average lineheight ) Problems will
of course arise if the text field contained lines of differing
heights.
Has anybody got / seen a module that provides all the usual
functionality of scroll bars but maybe move adaptable than the one i
have built.
many thanks,
steve
