QML?
import QtQuick 2.0

go-qml : basic skeletonfunc main() {

...
}
func run() error {
engine := qml.NewEngine()
component, err :=
engine.LoadFile(“file.qml”)
if err != nil {

}
win := component.CreateWindow(nil)
win.Show()
win.Wait()
return nil
}
25
go-qml : helloworld
helloworld.qml + helloworld.go (Exam1)
26
go-qml : manipulator
- QML의객체들을 Go에서조작(Exam2)
- Qt(c++) 에서는 connect 를사용해서 signal과 slot을연결- Go에서는 Window객체의 On 을통해서 signal과 slot을연결
27
go-qml : manipulator
- Go의변수/ 타입을 QML에서사용(Exam3, 4)
- func (ctx *Context) SetVar(name string, value interface{})
- func RegisterTypes(location string, major, minor int, types []TypeSpec)type TypeSpec struct {
Init interface{}
Name string
Singleton bool
}
28
go-qml : manipulator
- 이름(변수명..)의소문자변경value.Name => value.name
value.UPPERName => value.upperName
value.UPPER => value.upper
29
go-qml : manipulator
- Setter, Getter (Exam5)
type Person struct {
Name string
}
func (p *Person) SetName(name string) {
p.Name = name
}
func (p *Person) Name() {
return p.Name
}
30
go-qml : manipulator
- Paint (Exam6)
- Go Type에 Paint 리시버를제공된다.
- OpenGL 사용- qml.RegisterType(...) 으로 QML 에제공
31
go-qml : manipulator
- 리소스패키징- genqrc : resource 파일들을 go파일로 Pack
- 설치$ go get pkg.in/qml.v1/cmd/genqrc
- 사용의편리를위해서$GOPATH/bin/ 에생성되어있는 genqrc를,
/usr/local/go/bin 으로이동
32
go-qml : manipulator
- 리소스패키징- 리소스사용(경로지정)
: some/path -> qrc:///some/path
component, err := engine.LoadFile(“qrc:///some/path”)
33
go-qml : manipulator
- 리소스패키징 (Exam7)
- genqrc 사용법genqrc [options] <subdir1> [<subdir2> …]
: subdir 에있는리소스들을 qrc.go 파일로 pack
: Go 1.4에서는 go generate 사용//go:generate genqrc code images
$ go generate
34
go-qml : manipulator
- 리소스패키징- qrc.go
개발중에는매번갱신할필요는없다.
export QRC_REPACK=1
: qrc.go를갱신하지않고변경된내용을확인가능
35
go-qml : manipulator
- QML의객체들을 Go에서조작- Go의변수/ 타입을 QML에서사용- 이름(변수명..)의대소문자변경- Setter, Getter
- Painting
- 리소스패키징
