I am trying to implement a hand which scrolls the view by dragging in
the NSView.
in the mouseDown: NEView methods I have a dragging loop which reads
the difference between the last and the new mouse location while
dragging and then uses the ([self bounds]).origin and adds the
difference point and the bounds origin and the uses [self
scrollPoint:] with the new location.
This seems to sort of work, because it does scroll around, but it is
kind of a little weird. It is almost like it accelerates the way you
are dragging but when you go the other way it slows down then it
finally starts going the other way, it is almost like it has
momentum :). This is interesting but un desirable.
Does anyone have any suggestions?
I don't specifically know if this will help the performance. But
there is a mouseDrag event method inherited from NSResponder. Using this
method to control scrolling whilst dragging may smooth things out a bit.
