The simplest solution to your problem is to just have your heavy function
create and update a progress bar as it runs.
In your sample code, there really won’t be a way for your function to update a
progress bar as it runs unless you pass it in as another argument. In that
case, you would still have to make the updates from within your heavy function
anyway, so why not just create and delete the progress bar in it as well and
save yourself some trouble?
However, as a sort of generic example of your question about passing args
through one function to another, you can take in args and kwargs for a child
function as a tuple and dict respectively, and then unpack them onto the child
function:
def heavyFunc(path, anotherArg, someOtherKwarg=False):
pass
def progressBar(func, funcArgs, funcKwargs):
func(*funcArgs, **funcKwargs)
threading.Thread(None,progressBar, args=(heavyFunc, ('/some/path', 42),
{'someOtherKwarg': True})).start()
Also, make sure you’re using calls to nuke.executeInMainThread in your heavy
function where appropriate.
Hope this makes sense.

Subject: [Nuke-python] thread and progress bar
Hi fellow TD,
Im trying to create a progress bar for my lengthy process.
I had the hope I could make things modular by having a function creating the
progress bar and keep my lengthy process in other functions.
But I'm reaching a dead end here cause I need to pass argument to my heavy
function and the thread object does provide way to pass argument but apparently
only to the target function that's to say the function creating the progress
bar itself.
So anyone knows a way to pass arguments to my function being itself an argument
to the function creating the progress bar.
Im not sure Im very clear here so let me paste a bit of code:
def heavyFunc(path):
pass
def progressBar(func):
func()
threading.Thread(None,progressBar,args=(heavyFunc,) ).start()
so Id like to include the path argument in that last line, somewhere...but
where?
Hope someone can help! :)
Or if someone have another way of thinking that would solve the problem?
Cheers
