Mousewheel zoom rate

GoDiagram (6 and previous)

Is there a way to change the Ctrl+mousewheel zoom rate ?

First, look at the recent similar post:

Of course, instead of doing nothing when the Control key modifier is in effect, you can do something similar to what GoView.DoWheel does:

PointF oldpos = this.DocPosition; this.DocScale *= (1 + ((float)evt.Delta)/2400); PointF focus = ConvertViewToDoc(evt.ViewPoint); this.DocPosition = new PointF(oldpos.X + evt.DocPoint.X - focus.X, oldpos.Y + evt.DocPoint.Y - focus.Y);
But you can change the 2400 value to something that suits you better.

Thanks.



I implemented the desired zoom behavior in a GoView.DoMouseWheel override.
