@omz DropboxFilePicker (synchronous version)

[Phuket2]

@omz, is it a trivial matter to get your DropboxFilePicker utility to work synchronously rather than on ui.background. Well, the real question, can it easily be made to work so that wait_modal works. Want to include into a step as part of a bigger process. I have had some feeble attempts to modify, without much luck. First thing I tried was just to comment the @ui.background wrappers. I am sure, a bit more needs to be done.
Look, I know you must be busy. But if it's simple, would be great to have it. I also think also could benefit the community. If it's something you don't have time for. That's fine, with your permission, I will try and cut up your code and try again.

i had success simply replacing @ui.in_background with @run_async:

def run_async(func):
   from threading import Thread
   from functools import wraps

   @wraps(func)
   def async_func(*args, **kwargs):
      func_hl = Thread(target = func, args = args, kwargs = kwargs)
      func_hl.start()
      return func_hl

   return async_func

then wait_modal works.

@JonB , that's why you get paid the big bucks 😱

Really thank you. May have seemed easy to you, but not to me.
But your solution works perfect for me also.

@JonB , I searched for conditional decorators. So I found some stuff on stackflow. Not exactly what they did, but I did this and it seems to work.

_USE_ASYNC = False

def cond_decorator(func):
	from threading import Thread
	from functools import wraps
	
	@wraps(func)
	def async_func(*args, **kwargs):
		func_hl = Thread(target = func, args = args, kwargs = kwargs)
		func_hl.start()
		return func_hl
	
	if _USE_ASYNC:
		return async_func
	else:
		return ui.in_background(func)

Just so the DropboxFilePicker can work either way.
