Mousewheel on Windows 7 + MS Mouse + Intellipoint 7.1

Postby niver » Mon Mar 15, 2010 3:33 pm

The mousewheel handler code in CompareIt is likely a bit incorrect, because the scrollbars behaves erratically with a Microsoft Laser Mouse 6000 and Intellipoint 7.1 (likely with other MS mouses using Intellipoint too).

MS Mouses are probably the first mouses which produces smaller wheel delta values, values smaller than ±WHEEL_DELTA (120). You likely do integer divides of the delta and compare to -1 and 1 to decide whether the scrollbar should go up or down. Code like
switch ((int)(delta / WHEEL_DELTA))
case -1: .. go up
case 1: go down

This code obviously can't work with smaller deltas, could you please check it out and either process the smaller deltas into smaller scrollbar movements, or at least just compare to 0 with a relative operator instead:
if (delta < 0) .. go up
else (delta > 0) .. go down

Thank you.

I don't want to push too much, but do you have any ETA about this?

In fact it should be supported in fresh beta: http://www.grigsoft.com/wincmp4bu.zip .
