API comparison to Ritual?

[azzamsa]

Hi.

I tried many example apps from ritual example repo. The code seems very simple compared to the example app in cxx-qt example. As a non-C++ programmer myself, I feel intimidated by the code complexity I find in cxx-qt, I find ritual has simpler code to build a similar app.

• https://github.com/KDAB/cxx-qt/tree/v0.4.1/examples/qml_minimal
• https://github.com/rust-qt/examples/tree/master/qml/hello_qml

Is this because of the full potential described in the introduction chapter of the book https://kdab.github.io/cxx-qt/book/index.html? Or because it uses safe rust compared to ritual as described in this comparison https://github.com/KDAB/cxx-qt#comparison-to-other-rust-qt-bindings?

Are there any more points I need to know about why the CXX-Qt code looks so complex compared to ritual?

Thanks for maintaining CXX-Qt ❤️

The comparison you have right there is a bit of an apples-to-oranges comparison.
The ritual app you posted doesn't actually have any Rust behavior, apart from spinning up the QML app, whilst the CXX-Qt version does:

• Integration with CMake build system.
• Define a QObject subclass in Rust
• Expose the QObject subclass to QML
• Actually use the QObject subclass in QML
• Adds some tests

A fairer comparison would be between the ritual example and the cargo_without_cmake example from @Be-ing 's newest PR.

Furthermore, you could get rid of the CMakeLists.txt file in that example (it's just for integrating into the overall cxx-qt repo).
Also, the src/cxxqt_object.rs does something that the given ritual example doesn't do, so you could ignore that.

Then you basically end up with the same code your ritual example had :)
Relevant files being only:

• build.rs
• Cargo.toml
• src/main.rs
• and the qml/ folder.

With the new 0.5.0 release, it is now possible to write QML applications in Rust without needing C++ boilerplate. Take a look at the cargo_without_cmake example.

The new v0.5.0 release reduce many boilerplate code. Awesome!
