Using enaml just to invoke kiwisolver

[maxme1]

Hi!

Is it possible to create a nested widgets structure (e.g. some Labels in a Container) in Python without *.enaml files and generate the coordinates and sizes for each widget?

Basically, I am trying to render a static gui (without user interaction or resizing), and I would like to use kiwisolver to correctly position the widgets.

You can use kiwi without Enaml.

The layout helpers included with Enaml are pretty tightly coupled to the Enaml widget hierarchy.

You could what you ask procedurally, but it would probably be less effort to just use Kiwi directly.

I take that back. You might be able to create your own subclass of Constrainable, and use that with Enaml’s layout helper functions. You would just need to bootstrap your own Kiwi solver instance that solves the constraints generated by the helpers.

Or do you still actually want to use enaml just without the files (that is possible too)?

I found out here that each Container already has a solver which is recursively invoked to solve the constraints for the tree. However, I couldn't find the solver in the class definition, nor how to provide my own solver a solve the constraints.

Also, I couldn't figure out how to create a Container which has some children. Neither Container(children=[...]) nor

c = Container()
c.insert_children(None, [...])

seem to work.

I could implement my own widgets tree from scratch just by using kiwisolver, but enaml feels like a very promising framework for that.

Don’t give up so easy. You only spent like 20 minutes trying to “figure it out”.

I read all the docs from here, the relevant parts from here as well as parts of enaml's source code regarding the Container and Constrainable.

I am sorry if my question is too basic, but some pointers or examples would be very helpful.

I ended up generating python bindings for yoga. Thanks for your time though.
