### qt.go

Qt5 binding for Go (Golang) without CGO that aims to achieve Go's native compile speeds. Instead of using common bindings and heavy C++ wrapper code that forces you to compile and link time and time again, Qt.Go uses FFI so there's only a runtime dependency.

### Features

* Binding code with no CGO compile cost

* Popular Qt5 packages (widgets/QML/extras) support

* Simple go-uic, go-rcc tools

* full signal/slot support

* protected method override support

* default arguments and value wrapper functions

* Class/Method/Function/Enum comment for godoc

* Go side signal/slot definition (experimental)

### Multiple platforms support

All platforms should be supported, for now some of them are tested:

* Archlinux/Ubuntu16+

* MacOS

* Android

* Windows

### Installation

##### requirement

* go 1.9+

* libffi

* dlfcn (windows)

##### FFI

Make sure libffi is installed

Debian based: `apt-get install libffi-dev`

Arch based: `pacman -S libffi`

MacOS: `brew install libffi`

##### qt.go:

    go get -v -u github.com/kitech/qt.go

    

##### runtime dependency:

    git clone https://github.com/kitech/qt.inline.git

    cd qt.inline

    cmake .

    make

    cp libQt5Inline.so /usr/lib/libQt5Inline.so

##### uic/rcc

    go get -v -u github.com/kitech/qt.go/cmd/go-uic

    go get -v -u github.com/kitech/qt.go/cmd/go-rcc

[Full Installation](https://github.com/kitech/qt.go/blob/master/install.md)

### Examples

    package main

    import "os"

    import "github.com/kitech/qt.go/qtwidgets"

    func main() {

        app := qtwidgets.NewQApplication(len(os.Args), os.Args, 0)

        btn := qtwidgets.NewQPushButton1("hello qt.go", nil)

        btn.Show()

        app.Exec()

    }

### Internals

Qt.Go uses FFI to call wrapped Qt functions and methods, so there is no compile/link time dependency on Qt, only a run time dependency.

This should make the development and testing phases much faster.
