(mirror) OCaml bindings to Qt toolkit.

cuite's Issues

Toward MVP: minimal documentation

Explain how Qt concepts map to OCaml.
Provide tutorials to get started:

• basic widgets
• event dispatching (using delegates rather than inheritance)
• simple mainloop
• Lwt mainloop

Optional: provide some infrastructure to add ocamldoc to generated files.

Toward MVP: support Qt painter

Painter is one of the low-level API that is better supported by manually writing the API rather than generating it.
It is ubiquitous enough that it should be part of the first release.

Toward MVP: port more examples

Existing examples are partial and more examples are needed.

build error: undefined reference to `qt_version_tag'

When running make (with --verbose added to dune), I get the following error:

OCaml threading is not supported properly

The current allocator only supports up to one OCaml thread and one C++ (Qt) thread.
This is because the state is global and not saved on OCaml context switch.
