protobuf-qml's Issues

Qt 5.8 - Qt 5.9 compilation fail

Could not compile with Qt 5.9.
I found commit in QtQML #qt/qtdeclarative@8a63837 which deprecates QQmlContextWrapper

So, they changed corresponding API in Qt 5.8...

Add alias to count method

Like QList, define count, size and length methods.

Add toString method to generated message

In QML, console.log on a message prints only "Object object".

Reorganize test directory

Move those tests that use "legacy" API to a sub-directory.

Need simple example to communicate typical use case

Something like sending object through QtWebChannel.
Problem is that currently there's no binary support in QML out of the box.

Plan A is to implement thin QByteArray wrapper as part of the library code.
Plan B is to wait for ongoing upstream ArrayBuffer/TypedArray implementation.

Cannot install prerequisites per INSTALL

Please check that the PPA name or format is correct.

setup.py needs setuptools

/usr/local/src/protobuf-qml$ ./tools/build_dependencies.py --shared
...
Traceback (most recent call last):
  File "setup.py", line 11, in <module>
    from setuptools import setup, Extension, find_packages
ImportError: No module named setuptools
[/usr/bin/python setup.py build] failed with exitcode 1.

Test against latest gRPC 0.13.0

Add appveyor build

Consider safer API for generated javascript

Currently generated code uses simple key-values.

Since a part of benefit using schematized messages comes from code safety, API with setter/getter might better suite here.
That way, an invalid method call results in QML error.
