Overview

qmlrs - QtQuick bindings for Rust

qmlrs allows the use of QML/QtQuick code from Rust, specifically

Rust code can create a QtQuick engine (QQmlApplicationEngine) with a loaded QML script
QML code can invoke Rust functions

…with certain limitations. The library should be safe (as in not unsafe) to use, but no promises at this time. Reviews of the code would be welcome.

News

See the Changelog for the version history and what's waiting in master to be released.

Requirements

The library consists of a Rust part and a C++ part. The C++ part will be compiled automatically when building with Cargo. You will need cmake, Qt5 and a C++ compiler that can compile Qt5 code. Your Qt5 installation should have at least the following modules: Core, Gui, Qml, Quick and Quick Controls.

If you are installing Qt5 from source, please note that passing "-noaccessibility" to the configure script disables the qtquickcontrols module.

Usage

Add the latest version of qmlrs from crates.io in your project's Cargo.toml.

Example

This is the Rust code for an application allowing the calculation of factorials. You can find the corresponding QML code in the examples directory.

#[macro_use]
extern crate qmlrs;

struct Factorial;
impl Factorial {
    fn calculate(&self, x: i64) -> i64 {
        (1..x+1).fold(1, |t,c| t * c)
    }
}

Q_OBJECT! { Factorial:
    slot fn calculate(i64);
}

fn main() {
    let mut engine = qmlrs::Engine::new();

    engine.set_property("factorial", Factorial);
    engine.load_local_file("examples/factorial_ui.qml");

    engine.exec();
}

To run the above example, execute cargo run --example factorial in the project's root directory.

Note regarding the Qt event loop and threads

Creating an Engine automatically initializes the Qt main event loop if one doesn't already exist. At least on some operating systems, the event loop must run on the main thread. Qt will tell you if you mess up. The .exec() method on views starts the event loop. This will block the thread until the window is closed.

Licensing

The code in this library is dual-licensed under the MIT license and the Apache License (version 2.0). See LICENSE-APACHE and LICENSE-MIT for details.

install problem on ubuntu

hi,

i use ubuntu with rustc 1.2.0-nightly (764877650 2015-06-12) and qt: http://download.qt.io/official_releases/qt/5.4/5.4.2/qt-opensource-linux-x64-5.4.2.run any idea what is missing causing the build to fail?

Finish (Travis) CI integration

It would be really nice to have a CI integration that at least builds the library and the examples. There already exists https://travis-ci.org/cyndis/qmlrs/ from a year ago - maybe it can be brought to live with stable rust?

Fix QVariant enum

This enum does not match the one in ext/libqmlrswrapper/libqmlrswrapper.cpp (The rust version does not have a Bool slot). As a consequence, the enumeration values are different and hence QrsVariant::String has different values in rust and C. This caused a bug where the strings from QML were not recognised as strings by the Rust code (ffi::qmlrs_variant_get_type(var) != QrsVariantType::String). This commit seems to fix the issue, at least in regards to my own project.

QT5 I installed with homebrew. I tryning all recommendation from issue #25, but no results.

opened by kuznetsovin 7

Make build.rs play nice with OSX + homebrew.

Since QT5 and QT4 supply many of the same libs and QT4 is much more widely used (according to the Formula's keg_only declaration) homebrew doesn't link QT5 by default. To work around this we need to nudge pkg-config and cmake in the right direction for them to find QT5.

Fixes #25

qmlrs not building static library

Starting with a bare project I added the qmlrs requirement (0.1.1) and built it. It failed to build the static library.

I didn't install Qt5 from homebrew. Instead I symlinked it to the real location. However the pkgconfig directory and everything else is there, so it should still work.

cmake and pkg-config work.

White-Oak/qml-rust

Is there any relation to White-Oak/qml-rust? is this a parallel project with the same aims? Wouldn't it be good to join your forces? I'd love to see good,stable Qt5/QML bindings for Rust - but developing 2 different in parallel is a bit much of a needless effort?

Don't get me wrong, this is just a qustion.

Trying to cargo build on OS X Mojave

When I attempt to run cargo run --example factorial

I get the below error library not found for -lstdc++

I have googled this and it appears that stdlib has changed in XCODE

recommendations are to replace the following in the CMakeLists.txt file set(CMAKE_CXX_FLAGS "-stdlib=libc++")

I have performed this step and still get the above error. It appears that the changes in CMakeList.txt file are not being read.

Is there another location in the build process that I can change the stdlib?

Thanks

Support ChartView

Without this a qml file using a ChartView will crash at runtime. According to https://stackoverflow.com/questions/51532648/qml-crash-in-qt-5-9-help-to-read-stack-trace this is expected and an application using ChartView needs to use QApplication instead of QGuiApplication. This also matches the Qt Charts documentation:

Note: Projects created with Qt Creator's Qt Quick Application wizard are based on the Qt Quick 2 template that uses QGuiApplication by default. All such QGuiApplication instances in the project must be replaced with QApplication as the module depends on Qt's Graphics View Framework for rendering.

Can't build qmlrs because CMake can't find Qt5 (Windows)

When building qmlrs, I got this error message:

thread 'main' panicked at 'cmake produced stderr: CMake Warning at CMakeLists.txt:24 (find_package):
  By not providing "FindQt5Core.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "Qt5Core", but
  CMake did not find one.

  Could not find a package configuration file provided by "Qt5Core" with any
  of the following names:

    Qt5CoreConfig.cmake
    qt5core-config.cmake

  Add the installation prefix of "Qt5Core" to CMAKE_PREFIX_PATH or set
  "Qt5Core_DIR" to a directory containing one of the above files.  If
  "Qt5Core" provides a separate development package or SDK, be sure it has
  been installed.
 ...

It goes on but it is all related to not being able to find Qt.

I tried to fix this by setting the CMAKE_PREFIX_PATH: set(CMAKE_PREFIX_PATH "E:/Qt/5.9.1/mingw53_32/"), but that doesn't seem to work at all.

I had to set each packages path individually for that error to go away:

set(Qt5Core_DIR "E:/Qt/5.9.1/msvc2017_64/lib/cmake/Qt5core")
set(Qt5Quick_DIR "E:/Qt/5.9.1/msvc2017_64/lib/cmake/Qt5Quick")

But then another error showed up:

thread 'main' panicked at 'called `Result::unwrap()` on an `Err` value: "`\"pkg-config\" \"--libs\" \"--cflags\" \"Qt5Core Qt5Gui Qt5Qml Qt5Quick\"` did not exit successfully: exit code: 1\n--- stderr\nPackage Qt5Core was not found in the pkg-config se

ibcore\result.rs:860:4

Doing a backtrace, the error occured on the last line of build.rc (92).

I tried to set the PKG_CONFIG_PATH environmental variable to E:\Qt\5.9.1\mingw53_32\lib\pkgconfig, but that doesn't seem to do anything, any ideas?

Thanks

Passing non-primitive types to template

Disclaimer: completely new to Rust and QML.

I want to be able to return a Vec<CustomType> and be able to iterate over the vector from within my QML template. For instance, I fetch a vector of User's from a DB. How can I pass this vector to my QML template?

I've tried passing an array of primitives without luck. What's the idiomatic way to handle this?

Thank you!

Cross compile crash. RPi.

I'm testing cross compile this lib for Raspberry Pi 2.

Mount RPi rootfs to /mnt/rasp-pi-rootfs/. Create symlink in /usr/local to /mnt/rasp-pi-rootfs/usr/local/QtDIR.
Create simple test bin with cargo new hello --bin and add qmlrs to dependencies.
Add target to ~/.cargo/config

[target.armv7-unknown-linux-gnueabihf]
linker = "/mnt/rasp-pi-rootfs/usr/bin/arm-linux-gnueabihf-gcc"

First run cargo build --target=armv7-unknown-linux-gnueabihf for fetch dependencies.
Add

set(CMAKE_SYSTEM_NAME Linux)
set(CMAKE_SYSROOT /mnt/rasp-pi-rootfs)
set(CMAKE_C_COMPILER /home/di-erz/projects/images/gcc-4.7-linaro-rpi-gnueabihf/bin/arm-linux-gnueabihf-gcc)
set(CMAKE_CXX_COMPILER /home/di-erz/projects/images/gcc-4.7-linaro-rpi-gnueabihf/bin/arm-linux-gnueabihf-g++)
set(CMAKE_FIND_ROOT_PATH_MODE_PROGRAM NEVER)
set(CMAKE_FIND_ROOT_PATH_MODE_LIBRARY ONLY)
set(CMAKE_FIND_ROOT_PATH_MODE_INCLUDE ONLY)
set(CMAKE_FIND_ROOT_PATH_MODE_PACKAGE ONLY)

to CMakeLists.txt to qmlrs-0.1.1/ext/libqmlrswrapper. Then build static libqmlrswrapper

$ cd qmlrs-0.1.1/ext/libqmlrswrapper/build

$ PATH=$PATH:/mnt/rasp-pi-rootfs/usr/local/Qt-rasp2-5.7.0 \
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/mnt/rasp-pi-rootfs/usr/local/Qt-rasp2-5.7.0/lib \
PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/mnt/rasp-pi-rootfs/usr/local/Qt-rasp2-5.7.0/lib/pkgconfig/ \

CMAKE_C_COMPILER=/mnt/rasp-pi-rootfs/usr/bin/arm-linux-gnueabihf-gcc \
cmake ../

$ make

Return to test project dir, clean, and rebuild.

$ cd projects/hello

$ CMAKE_SYSROOT=/mnt/rasp-pi-rootfs \
PATH=/mnt/rasp-pi-rootfs/usr/local/Qt-rasp2-5.7.0:$PATH \

cargo build --target=armv7-unknown-linux-gnueabihf --verbose
