-r"""servermanager is a module for using paraview server manager in Python.
-One can always use the server manager API directly. However, this module
-provides an interface easier to use from Python by wrapping several VTK
-classes around Python classes.
-
-Note that, upon load, this module will create several sub-modules: sources,
-filters and rendering. These modules can be used to instantiate specific
-proxy types. For a list, try "dir(servermanager.sources)"
-
-A simple example:
- from paraview.servermanager import *
-
- # Creates a new built-in session and makes it the active session.
- Connect()
-
- # Creates a new render view on the active session.
- renModule = CreateRenderView()
-
- # Create a new sphere proxy on the active session and register it
- # in the sources group.
- sphere = sources.SphereSource(registrationGroup="sources", ThetaResolution=16, PhiResolution=32)
-
- # Create a representation for the sphere proxy and adds it to the render
- # module.
- display = CreateRepresentation(sphere, renModule)
-
- renModule.StillRender()

- """Proxy for a server side object. A proxy manages the lifetime of
- one or more server manager objects. It also provides an interface
- to set and get the properties of the server side objects. These
- properties are presented as Python properties. For example,
- you can set a property Foo using the following:
- proxy.Foo = (1,2)
- or
- proxy.Foo.SetData((1,2))
- or
- proxy.Foo[0:2] = (1,2)
- For more information, see the documentation of the property which
- you can obtain with
- help(proxy.Foo).
-
- This class also provides an iterator which can be used to iterate
- over all properties.
- eg:
- proxy = Proxy(proxy=smproxy)
- for property in proxy:
- print property
-
- For advanced users:
- This is a python class that wraps a vtkSMProxy.. Makes it easier to
- set/get properties.
- Instead of:
- proxy.GetProperty("Foo").SetElement(0, 1)
- proxy.GetProperty("Foo").SetElement(0, 2)
- you can do:
- proxy.Foo = (1,2)
- or
- proxy.Foo.SetData((1,2))
- or
- proxy.Foo[0:2] = (1,2)
- Instead of:
- proxy.GetProperty("Foo").GetElement(0)
- you can do:
- proxy.Foo.GetData()[0]
- or
- proxy.Foo[0]
- For proxy properties, you can use append:
- proxy.GetProperty("Bar").AddProxy(foo)
- you can do:
- proxy.Bar.append(foo)
- Properties support most of the list API. See VectorProperty and
- ProxyProperty documentation for details.
-
- Please note that some of the methods accessible through the Proxy
- class are not listed by help() because the Proxy objects forward
- unresolved attributes to the underlying object. To get the full list,
- see also dir(proxy.SMProxy). See also the doxygen based documentation
- of the vtkSMProxy C++ class.

- sphere = Sphere(ThetaResolution=16, PhiResolution=32)
-
- # Apply a shrink filter

+ For advanced users:

+ For proxy properties, you can use append:
