Hi Doug,
It's a common misconception that a scrollbar should take the values 0 to
100 when the width of the 'space' that it scrolls is 100. Programmers who do
this are responsible for all the times that you scroll to the end of a
document and find yourself looking at a single line and a page of blank space,
or a single character column on the left and the rest blank. Those who
additionally get their -/+1's wrong will give you a completely blank space to
look at. Most annoying!! :-(
So what am I talking about?
A horizontal scrollbar should be given the range that the <left hand side>
will take. Not the range of the entire space. This is so that when the user
scrolls as far as possible to the right, the scrollbar value <plus> the width
of the viewing area will give the maximum value at the <right hand side>.
So, I think I'm glad that your maximum value is 91. Because this means
that your view will fit what it's showing without leaving huge areas of white
space.
Or are you using the scrollbars for something different, I wonder? That
mention of Big Step has me puzzled. Can you tell us more ?
Regards,
Fergus
