[Paraview-developers] Using TIME_LABEL_ANNOTATION

[Michael Reuter]

Yes, the TIME_LABEL_ANNOTATION is called via another function, but in 
the RequestInformation function. The plugin code can be found here: 
https://github.com/mantidproject/mantid/blob/6540_time_axis_labeling/Code/Mantid/Vates/ParaviewPlugins/ParaViewReaders/MDEWNexusReader/vtkMDEWNexusReader.cxx. 
Line 154 starts the RequestInformation function and the function that 
calls TIME_LABEL_ANNOTATION is at Line 200. Our reader deals with both 
3D (no "time") and 4D ("time") datasets. The file I am testing on is a 
known 4D dataset.

Can you try this exercise since you don't have my code set up? I 
modified the vtkExodusIIReader.cxx in my git checkout of ParaView to 
call TIME_LABEL_ANNOTATION in the AdvertiseTimeSteps function call. 
After compiling, I used the can.ex2 file to check to see if the time 
label got passed to the time control widget. For me, it did not. 
However, the information properties panel shows the new time label. The 
patch is attached.
