How to execute shelf button via python?

[haggi 37]

Hi,

I'd like to execute a shelf button from python? Is this possible?

[DonRomano 63]

my_shelf_tool = hou.shelves.tool("my_shelf_tool_internal_name")
my_script = my_shelf_tool.script()
exec(my_script)

or

hou.SceneViewer.runShelfTool("my_internal_shelf_tool_name")

Thanks, that was fast.

Unfortunately I have problems with both methods. The first method gives me (with a simple test tool which creates a sphere):

>>> st = hou.shelves.tool("converter")
>>> s=st.script()
>>> exec(s)
Traceback (most recent call last):
  File "<console>", line 1, in <module>
  File "<string>", line 12, in <module>
NameError: name 'kwargs' is not defined
>>> 

And the other one seems only to work from within the UI, but I'd like to execute the shelf button from hython commandline.

Yeah I see, I'm getting this error too, because I guess the shelf tool needs some sort of info to set up kwargs and executing it from a script doesn't seem to give it the info. Why not creating a normal  script and then executing it with hython instead of creating a shelf tool ?

I just set the kwargs with:

kwargs={}

and it seems to work
