<div>Hi all,</div><div><br></div><div>I am doing a contour widget in VTK according to the example below:</div><div><br></div><div><a href="http://www.vtk.org/Wiki/VTK/Examples/Cxx/Widgets/ContourWidget">http://www.vtk.org/Wiki/VTK/Examples/Cxx/Widgets/ContourWidget</a>
</div><div><br></div><div>I want to make a certain control point as fixed, so the user can't drag it.</div><div>I want to do it for that particular point only.</div><div>I tried many methods, such as keypressactivationoff, draggableoff etc but did not work out.</div>
<div>Is there any way to do this?</div><div><br></div><div>Thanks.</div>
