A Rust binding of the wxWidgets cross platform toolkit.

This repo has been abandoned years ago. As I (original author) commented here, I'm trying this again with now stable and mature language and solid ecosystem in the another repo.

April 1st, 2022.

wxRust

master: / mac(0.10):

This is a Rust binding for the wxWidgets cross platform toolkit.

API

wxRust API documentation

How it works

The wxRust library is heavily based on the wxHaskell's wxc library.

The wxc is a C language binding for the C++ wxWidgets toolkit.

We utilize the rust-bindgen automatic rust binding generator for its _unsafe low-level binding.

And we generate an OOP-style high-level binding (other modules than _unsafe) by codegen.py code generator.

Build

We use CMake for cross platform build, but Windows platform is not yet tested.

For Linux build instructions, see INSTALL.linux.md

Build Prerequisite

Use following Rust compiler version for your wxRust branch. We're using Servo master's one for main development.

wxRust branch	Supported Rust compiler version
master	master

Install the wxWidgets 3.0 (2.9.5 or later is required) and CMake as below (in the case of Homebrew):

brew install wxmac
brew install cmake

With some tweak you may be able to compile wxRust with a bit older versions (2.9.0 < x < 2.9.4) of wxWidgets. See issue #21 comments for details.

Build the library

At the project root directory,

Checkout git submodules:

git submodule init # for the first time.
git submodule update

And generate Makefiles and make:

mkdir build
cd build
cmake ..
make

Compile and Run the Test program

At the CMake binary directory:

make test && ./test

On Mac, Run as below:

make Test.app
open ./Test.app # or open in Finder

Generate Documentation

At the CMake binary directory:

make doc

Generates a rustdoc documentation under doc directory.

wxrust's Issues

Can't build on Gentoo Linux with wxWidgets-3.0.0.0 installed from portage

Although I can build wxRust for MacOSX with wxWidgets-3.0.0 and (with some tweak) for Linux with wxWidgets-2.9.4.1, now after I upgraded wxWidgets on my Linux box to version 3.0.0.0 (present in official Gentoo portage), I'm facing following error:

[ 92%] Generating wxrust.dummy

... and so on, tons of lines lihe these ones.

need samples

we need testing this library.

I'll port some sample programs from wxWidgets samples.

CMake not working

I'm running this on Arch Linux with Rust 0.10.

$ cmake .. -DwxWidgets_CONFIG_EXECUTABLE=/usr/bin/wx-config
Re-run cmake no build system arguments
CMake Warning at CMakeLists.txt:4 (find_package):

Master Rust doesn't allow multiple file input

Currently the make will fail with master rustc. There are several times where multiple file names are passed to the rustc compiler. Which isn't allow.

generate OOP style safe wrapper

let codegen.py to generate OOP style safe wrapper

Release 0.1 as the last point supporting rust-0.8 compiler.

As the rust 0.10 was released, I want to drop the rust 0.8 compiler support.
I'll tag the last fine revisions for each compilers currently supported, then drop rust 0.8 support.

Travis OS X CI

I'm requesting wxmac bottling for this.
Homebrew/legacy-homebrew#25645

If above Issue is resolved, we should be able to build on OS X CI environment.
see b604661

Use SiegeLord/RustCMake

We have a very tiny rust.cmake file, we can use SiegeLord's one.

Update the rust-servo branch's compiler to servo's one in 2014/04.

almost rust-0.10

Update or re-create the rust-servo branch.

Current one is outdated.

Register with Travis CI

See http://hiho.io/rust-ci/

Necessary steps: http://hiho.io/rust-ci/help/

Update the rust-mac branch base to rust-0.10 branch.

Since homebrew's rust is updated to rust-0.10.

make wxObject params and return values Option<T>.

if it's NULL, we shouldn't call it's method.

let window = frame.findWindow("Window Name");
// if window not found, window becomes wxWindow(NULL),
// you shouldn't call on it, but you can do accidentally...
let label = window.getLabel(); // BOOOM

Update for 0.11

Any chance of getting wxRust updated to support 0.11?

Is this repo in active development?

Hello,

Looking over the commit graph there appears to be no history since 2017. I was wondering if we could hand this off to someone to start maintaining or if we should create another repo to start from?

I don't want to loose all the work on this repo. It is also a little frustrating that WxWidgets wiki links to this repo as a binding and there is no support. GUI options are still a little limited in Rust but making progress.

I am coming from WxWidgets in C++ and thought this would be a good option to start with seeing as I am familiar with the lib.

SIGSEGV while running test on Linux

As I mentioned in #19, although I can finally build wxRust on Linux, test application is crashed by SIGSEGV whenever I push the button. Details are as follows:

SingleInstanceChecker isAnotherRunning failing

SingleInstanceChecker::newDefault().isAnotherRunning() always returns a non zero value (looks like a pid), as if another instance of the app is running.

Some simplified code, to show my use:

fn main() {
    const NULLPTR: *mut c_void = 0 as *mut c_void;
    let closure = Closure::new(wx_main as *mut c_void, NULLPTR);
    let args: Vec<*mut i32> = Vec::new();
    RustApp::initializeC(&closure, args.len() as i32, args.as_ptr() as *mut *mut i8);
}

extern "C"
fn wx_main() {
    let sic = SingleInstanceChecker::newDefault();
    if sic.isAnotherRunning() == 0 {
        println!("Fresh app! 😻");
    } else {
        println!("Another running! {} 😿", sic.isAnotherRunning());
        panic!("Outahere");
    }
    let frame = Frame::new(&Window::null(), ID_ANY, "Hello, wxRust!", -1, -1, -1, -1, DEFAULT_FRAME_STYLE);
    frame.show();
    frame.raise();
}

Trying the check prior to RustApp init results in /usr/include/wx-3.0/wx/snglinst.h(58): assert "static_cast<wxApp*>(wxApp::GetInstance())" failed in CreateDefault(): must have application instance, so I figure wx_main is the right place for checking.

For info, the check works fine in the underlying wxHaskell:

main :: IO ()
main = do
  start $ singleMintegrator "fileName from elided args handling"

singleMintegrator :: String -> IO ()
singleMintegrator fileName = do
  sic <- singleInstanceCheckerCreateDefault
  running <- singleInstanceCheckerIsAnotherRunning sic

  if running
    then messageMintegrator fileName -- message existing instance
    else mintegrator fileName -- else set up new instance

Generate wx constants definitions from wx/defs.h

Cargonize wxRust

Cargo looks very promissing.

Drop rust-0.8 compiler support.

The link to the documentation leads to malware/advertisement sites

The rust-ci.org domain is now for sale. When I first visited the link, it lead to a beeping page warning about iOS malware that both ublock origin and firefox warned me about. Now it just leads me to the domain sale page.

Build for Linux

I had to make some changes in order to be able to build for Linux (Gentoo Linux with wxGTK-2.9.4.1-r1 from distribution):

1. a symlink ../lib -> /usr/lib as clang's stddef.h need to be found in ../lib/clang/3.3/include during binding generation
2. _unsafe.rs.patch should not be applied on Linux:
   diff --git a/CMakeLists.txt b/CMakeLists.txt
   index 2a8e19e..da4054f 100644
   --- a/CMakeLists.txt

3. wxWidgets implementation for Linux is wxGtk not wxMac:

   return Popen(cmdline, stdout=PIPE).communicate()[0]
  

4. For some reason rust-bindgen was unable to proceed with fail_on_bitfield, therefore I had to patch it too (patch for commit 6b77ae6202cec2204795504b89fa944400245667):

  +// name, parent.spelling());

  let field = mk_fieldinfo(name, ty, bit);
  fields.push(field);
  }

Now build completes and I am able to run test. Unfortunately, when I press the button, it segfaults after printing "hello!"

crates.io

I want to include wxRust in my Cargo.toml but I don't know what to use. I don't even know if wxRust is on crates.io at all. Would you mind publishing it there and adding a note in the repository specifying where it is?

Thanks!

make built programs relocatable

for mac:
maybe we should use @rpath or something.

for unix:
have something to do with #31 (comment) ?

Make rust-0.10 branch.

memory management for non-GUI classes

replace extern fn generator from my own to rust-bindgen

The rust-bindgen handles not only functions but also constants or struct definitions.
And it may help generating OOP style wrapper with its AST output that may be handled more easily than wild header files.

Build problems

I'm trying to build this, but keep getting an error - if I figure i tout I'll update this and maybe PR the README or whatever's needed - meanwhile here's the problem I have.
