How to build a nice interactive Textual representation of a hierarchical parameter container ?

[paugier]

I like to use Textual to build small apps to launch/control/post-process computations using Fluiddyn Python libraries. The API is often based on instances of Fluiddyn ParamContainer

For example, this tutorial shows how to compute Particle Image Velocimetry with Fluidimage:

from fluidimage.piv import Work

params = Work.create_default_params()
# the user can interact with the object `params` to
# - read the default parameters
# - read the documentation on parameters
# - change the parameters

params.series.path = ...
params.piv0.shape_crop_im0 = 64
params.multipass.number = 2

# params is a hierarchical object, a `ParamContainer` containing other `ParamContainer` objects (`series`, `piv0`, `multipass`, etc.)

work = Work(params)
result = work.process_1_serie()

I'd like to be able to produce a nice Textual representation of a ParamContainer to be able to graphically interact with it (discover the possible parameters, read the documentation and of course modify the parameters).

I see that there are plenty of nice widgets that could be used for different types of parameters. I could even add data in the ParamContainer object on which widget should be used for which parameter.

However, right now I don't see how to handle in Textual the hierarchical nature of ParamContainer objects. So here is my question:

How could one represent in Textual hierarchical Python objects containing parameters ?

While looking at all of the widgets, did you consider Tree?

[paugier]

If I understand correctly, Trees are designed "for displaying and navigating data in a tree", but I can't add widgets in a tree to be able to modify the data. So it seems that I would need a bit more than a Tree.

Correct, you can't place widgets within a Tree, but you could use a Tree to navigate the properties and have an adjacent container of widgets that pertain to the property that is selected (as one approach).
