Examples

The following code example shows how to override the OnMouseWheel method to zoom the WorkflowView object based on the Delta property of the MouseEventArgs and to return false so that other components in the designer architecture can process the method.

protected override bool OnMouseWheel(MouseEventArgs eventArgs)
{
    mouseDown = false;
    return true;
}

Protected Overrides Function OnMouseWheel(ByVal eventArgs As MouseEventArgs) As Boolean
    mouseDown = False
    Return True
End Function
