Re: [Nplot-devel] Zooming with NPlot

[Hywel T. <hy...@co...>]

The PlotSurface needs to have the focus in order to receive MouseWheel 
events.  If you change the OnMouseMove (in Windows.PlotSurface2D) to:-

protected override void OnMouseMove(MouseEventArgs e)
{
	this.Focus();	// Set Focus to receive MouseWheel events
	DoMouseMove( e, this );
	base.OnMouseMove( e );
}

then you will see the ABC demo working as intended, with the plot 
getting Focus when the mouse is moved over it.
