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)
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
FFI

Make sure libffi is installed

Debian based:

apt-get install libffi-dev

Arch based:

pacman -S libffi

Full Installation

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.NewQPushButton_1("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.
