[Paraview] How to simply "Reload" a data file

[Sebastien Jourdain]

There is a way if you are willing to create your own Plugin for the reader
that you are using.

The XML should look like that

<ServerManagerConfiguration>
<ProxyGroup name="sources">
<SourceProxy name="ReaderWithButton" base_proxygroup="sources"
base_proxyname="LegacyVTKFileReader">
      <Property name="Refresh" command="Modified"
panel_widget="command_button"/>
      <Hints>
        <ReaderFactory extensions="vtr" file_description="Refresh (Legacy
VTK files)" />
      </Hints>
    </SourceProxy>
</ProxyGroup>
</ServerManagerConfiguration>

Unfortunately the hints/ReaderFactory didn't properly worked which prevent
its usage from a simple XML file, but if you register it as a real plugin
with the XML-GUI one, you should be fine with the OpenFile dialog.

The remaining thing for you would be to figure out the proxyname of the
reader that you are willing to extend.

If you don't mind using python to create the reader, then you can do
something like that in the python shell.

> r = ReaderWithButton(FileNames='/.../ParaViewData/Data/cone.vtr')
> Show()
> Render()
