Hi,<br><br>It's a sub-proxy that is used to define the probe location. The name of that is FixedRadiusPointSource. You can find that in filters.xml (partly shown below). The proxy definition of FixedRadiusPointSource is in utilities.xml (also partly shown below).<br>
<br>Hope this points you in the proper direction.<br><br>Andy<br><br>=========== snippet of filters.xml ====================<br> <SourceProxy class="vtkPProbeFilter"<br> label="Probe Location"<br>

The Probe filter samples the data set attributes of the<br> current data set at the points in a point cloud. The Probe<br> filter uses interpolation to determine the values at the<br>
selected point, whether or not it lies at an input point.<br> The Probe filter operates on any type of data and produces<br> polygonal output (a point cloud).</Documentation><br>

<br>
I'm trying to programmatically (C++) access the point coordinates displayed by the property panel widget after the p key is pressed. I have a pqPipelineSource pointer from when I created the Probe Location filter, but I can't seem to find any properties (tried Point, Center, WorldPosition) on the proxy that work. I also tried accessing those properties via the source proxy, but no luck either. If the proxy has the information, what is the correct property name? If not, where do I need to be looking?<br>
<br>
Thanks,<br>
