[Paraview] PV4.1, Custom Dock Widget: How to automatically add a glyph3d filter after loading data ?

Wed Sep 17 05:22:01 EDT 2014

Dear Utkarsh,

thanks a lot. I made a small mistake during cmake configuration. It 
works fine.

Question: Where can I find the "keywords" for

vtkSMPropertyHelper(...)

For example you used:

vtkSMPropertyHelper(cylinder,"Resolution").Set(18);

I would like to setup the glyph's settings in a similar fashion. For 
example:

// your code
...

//Createandinitializetheglyphfilter

vtkSMSourceProxy*  glyph  =  vtkSMSourceProxy::SafeDownCast(pxm->NewProxy("filters",  "Glyph"));

controller->PreInitializeProxy(glyph);
vtkSMPropertyHelper(glyph,"Input").Set(cylinder);
vtkSMPropertyHelper(glyph,"Source").Set(getSphereSource(glyph));

// what I would like to add to the glyph's settings
vtkSMPropertyHelper(glyph,"Scale Factor").Set(1.0);
vtkSMPropertyHelper(glyph,"Scale Mode").Set(scalar);
vtkSMPropertyHelper(glyph,"Masking").Set(All_points);
...

cylinder->UpdateVTKObjects();
...

For example I tried "ScaleFactor" and "Scale Factor" but they do not 
seem to work.

what are the data types for the .Set() functions ? For example in the 
case of Masking ? Where can I find the C++ masking options and its data 
type to be used with vtkSMPropertyHelper ? Or do you suggest another way 
of accessing these properties ?

Thank you very much.

Florian
