Dear all,<br><br>I want to mimic the Line Source of Paraview. So I ran into the XML in order to understand how the 3D widget is created, the one that makes available a picker through the 'P' key. Unfortunately, I didn't understand...<br>
<br>1- In sources.xml, I found a "LineSource" proxy description in the sources ProxyGroup, with label "Line" that match with the one available under the sources menu of Paraview.<br>2- In utilities.xml, I found another "LineSource" proxy, but with label "Line Source" in the extended_sources ProxyGroup.<br>
<br>The XML looks very usual, with DoubleVectorProperty for each point and an IntVectorProperty for the output line resolution, except the PropertyGroup. I didn't find in the paraview book the explanation of this <Hint><br>
<br>My questions are:<br>- What is the difference?<br>- What are the keyword in these XML descriptions that activate the 3D widget?<br>- Is the PropertyGroup involved in the interaction mecanism?<br><br>Thank you all,<br>
<br>Jerome<br>
