</div></div>I tried to do the same thing you did but in c++ and I get the same<br>
error. I'm still apparently missing a big concept about how these<br>
widgets work - can anyone explain them at a very high level?<br>
<br> planeWidgetX->SetInput(Polydata);<br>
planeWidgetX->SetPlaneOrientationToXAxes();<br></blockquote></div><br>The widget expects an image data as input, as stated in the doxygen documentation of the widget's SetInput method...<br><br>We should probably enforce that via a safedowncast in the SetInput method, instead of invoking an error later.. <br>
