 Thank you that's very helpful. Where will I find how to define the
 protocols on the python side? I've only found a wslink example that looks
 like this:

 from wslink import register as exportRPC
 from wslink.websocket import LinkProtocol

 class myProtocol(LinkProtocol):
 def __init__(self):
 super(myProtocol, self).__init__()

 @exportRPC("myprotocol.testButton")
 def testButton(self, nothing):
 print("*** HELP ")

 Pvpython isn't happy with this, but I'm not sure where to look for the
 right way to do it.

 Thank you,

Turns out you can't use capital letters for the protocol options (what
should I call them?), according to the discussion at this link. Some people
here might find it familiar:

 Hello all:

 Got some nice looking buttons and widgets, but I can't seem to find
 examples of how to deliver the button press or other widget output to my
 pvpython server. I imagine the steps are:

 1. Create a protocol on the python side. Can I use wslink.register, or
 is there paraviewweb functionality I should be using?

 2. Create a matching protocol on the js side, with
 ParaviewWebClient.createClient(), but I'm not seeing how to link the
 protocol to a function that can be linked to a button press.

 Also, this page, found via a google search, seems potentially useful,
 but gives me a 404.

 Many thanks,

Re: [Paraview] connecting buttons and python

[Scott Wittenburg]

That actually looks ok to me.  Why isn't pvpython happy with it?  What
version of ParaView are you running?  If it's a recent ParaView and the
problem is you can't import wslink, then setting up a virtualenv with the
missing modules (wslink and its dependencies) might be what you need.  See
this blog post for more information on how to use pvpython but also bring
in the modules in your virtualenv:

https://blog.kitware.com/using-pvpython-and-virtualenv/

If the problem is something else, we might need more details.

Hope this helps.

Cheers,
Scott

Re: [Paraview] connecting buttons and python

[Sgouros, Thomas]

Thank you that's very helpful. Where will I find how to define the
protocols on the python side? I've only found a wslink example that looks
like this:

from wslink import register as exportRPC
from wslink.websocket import LinkProtocol

class myProtocol(LinkProtocol):
def __init__(self):
super(myProtocol, self).__init__()

@exportRPC("myprotocol.testButton")
def testButton(self, nothing):
print("*** HELP ")

Pvpython isn't happy with this, but I'm not sure where to look for the
right way to do it.

Thank you,

 -Tom

[Paraview] connecting buttons and python

[Sgouros, Thomas]

Hello all:

Got some nice looking buttons and widgets, but I can't seem to find
examples of how to deliver the button press or other widget output to my
pvpython server. I imagine the steps are:

1. Create a protocol on the python side. Can I use wslink.register, or is
there paraviewweb functionality I should be using?

2. Create a matching protocol on the js side, with
ParaviewWebClient.createClient(), but I'm not seeing how to link the
protocol to a function that can be linked to a button press.

Also, this page, found via a google search, seems potentially useful, but
gives me a 404.

Many thanks,
