<div dir="ltr"><div>According to the tutorials and example code, you can create a vtkCallbackCommand() object and then call SetCallback on it with a callback function, as in:</div><div><br></div><div>
<pre class="gmail-de1">  vtkSmartPointer<span class="gmail-sy1"><</span>vtkCallbackCommand<span class="gmail-sy1">></span> keypressCallback <span class="gmail-sy1">=</span> 
      vtkSmartPointer<span class="gmail-sy1"><</span>vtkCallbackCommand<span class="gmail-sy1">></span><span class="gmail-sy4">::</span><span class="gmail-me2">New</span><span class="gmail-br0">(</span><span class="gmail-br0">)</span><span class="gmail-sy4">;</span>
