GitHub - kitech/qt.go: Qt binding for Go (Golang) aims get Go's compile speed again. (original) (raw)

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

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.
