# dart-qtbindings
This is a proof of concept of Qt bindings for Dart.
The goal is only to showcase the C++ binding generator for Dart, Dartagnan.
There's no intention in creating production ready Qt bindings.
# Build
```bash
cmake .
cmake --build .
```
You now have a Qt bindings library: `generated/QtDartBindings/libQtDartBindings.so`
These are the C wrappers produced by our dart generator.
# Run
`libQtDartBindings.so` needs to be in your library path, so edit PATH (Windows), LD_LIBRARY_PATH (Linux)
or DYLD_LIBRARY_PATH(macOS). On mac you'll need to disable system integrity protection though.
Or alternatively, edit:
```bash
generated/QtDartBindings/dart/lib/Bindings.dart: _dylib = ffi.DynamicLibrary.open('libQtDartBindings.so');
```
and use an hardcoded absolute path in the source.
On Linux, it's just:
```
export LD_LIBRARY_PATH=build-dev/generated/QtDartBindings/:$LD_LIBRARY_PATH
```
Now run:
```
cd app
dart pub get # Could this be done automatically ?
dart run bin/main.dart
```
# Regenerating the Bindings
Be sure to build and install `dartagnan` and put it in path.
Then run:
```
dart pub get
dart refresh_bindings.dart
```
# Repo Layout
`app/`
Our dart test app, which shows a Qt window.
`generated/`
Contains all the code generated by shiboken.
Includes the dart classes which users will use, and also the intermediate
C and C++ glue which calls the target C++ code.
`typesystem.xml`
Used by shiboken, at "binding generation time".
The file for configuring the shiboken generation. Lists all classes we want bindings.for
`bindings_global.h`
Used by shiboken, at "binding generation time". Includes all headers we want bindings for.
`shiboken_snippets/`
Sometimes shiboken needs a little help and we can provide some snippets for it, so we say
exactly what we want generated.
# Known Issues
* macOS: "NSWindow drag regions should only be invalidated on the Main Thread!"
See https://github.com/dart-lang/sdk/issues/38315 , patches welcome
