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.
cmake .
cmake --build .You now have a Qt bindings library: generated/QtDartBindings/libQtDartBindings.so
These are the C wrappers produced by our dart generator.
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:
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
Be sure to build and install dartagnan and put it in path.
Then run:
dart pub get
dart refresh_bindings.dart
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.
- macOS: "NSWindow drag regions should only be invalidated on the Main Thread!" See dart-lang/sdk#38315 , patches welcome
