In this example:<br><a href="http://www.vtk.org/Wiki/VTK/Examples/Cxx/Widgets/SphereWidgetEvents">http://www.vtk.org/Wiki/VTK/Examples/Cxx/Widgets/SphereWidgetEvents</a><br><br>I am trying to handle StartInteractionEvent: and InteractionEvent as recommended by the documentation: <a href="http://www.vtk.org/doc/nightly/html/classvtkSphereWidget.html#details">http://www.vtk.org/doc/nightly/html/classvtkSphereWidget.html#details</a><br>
<br>However, these events do not seem to be triggered ("InteractionEvent!" is not displayed when I move the mouse). LeftButtonPressEvent works as expected (the output "LeftButtonPressEvent!" is displayed when I click the left button).<br clear="all">
<div><br>Does anyone know why these events events are not behaving as I'd expect?<br><br>Thanks,<br><br>David</div>
