<p class="MsoNormal">Hello,<o:p></o:p></p>
<p class="MsoNormal">I’m in the process of evaluating vtk in an Eclipse RCP application.<o:p></o:p></p>
<p class="MsoNormal">I’ve successfully used vtk in NetBeans RCP applications so I’m hoping for a similarly successful out come!<o:p></o:p></p>
<p class="MsoNormal">Anyway, while experimenting with SWT, I’ve run into an issue where my SWT component that embeds a vtkPanel<o:p></o:p></p>
<p class="MsoNormal">brings the entire application down if I setup my pipeline using SetInputConnection. If I switch it to SetInput, it works fine.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I’ve seen similar behavoir with Swing and it had to do with threading. I’m new to SWT so it’s not clear to me,<o:p></o:p></p>
<p class="MsoNormal">if I want to use SetInputConnection/GetOutputPort for my pipeline setup, where is it “safe” to make these calls?<o:p></o:p></p>
