You can edit the help knob by simply setting it's string:
node['help'].setValue( 'this is how to use this gizmo...' )
Or in the group's UI: right click > Edit Help
I'm not sure what the actual Help_Knob object is (the above mentioned
knob is actually a EvalString_Knob).
I remember a feature request from D2Software days to mimic a Shake
feature which would allow you to dynamically link nodes' help to a url.
It would be great to have an easy mechanism for this.
The help knob is pretty useless for what you're after though, as it
won't allow you to click on it's text.
Your best bet is to add a right click menu item to all nodes' properties
panel and call a function that grabs the node's class and builds a url,
then opens it:
def loadWiki():
node = nuke.selectedNode()
nodeClass = node.Class()
url = 'www.myWiki/%s' % nodeClass
print 'opening', url
nuke.tcl('start %s') % url
nuke.menu('Properties').addCommand( 'Open Wiki page', loadWiki )
I used the tcl command to open a url as nukescripts.start() doesn't seem
to do anything (might be a bug).

hi everybody,
just wondering if anyone knows of a best practice for adding a help to
all custom gizmos. I want to be able to link them to our wiki page for
a quick reference for new artists.
so a couple questions i have are:
what is the Help_Knob, is this what i want? it doesn't appear to
serialize so how does one use it? is it possible to setup an onCreate
callback that will add the Help_Knob dynamically for any custom gizmo?
that begs me to ask, is there a way to detect if a node is an internal
Nuke one vs. a custom implementation?
any ideas or thought would be more then welcome.
cheers,
josh
