Golang gtk_init_with_args 예제들

예제 #1

파일: uitask_unix.go 프로젝트: sjn1978/ui

func uiinit() error {
	var err *C.GError = nil // redundant in Go, but let's explicitly assign it anyway

	// gtk_init_with_args() gives us error info (thanks chpe in irc.gimp.net/#gtk+)
	// don't worry about GTK+'s command-line arguments; they're also available as environment variables (thanks mclasen in irc.gimp.net/#gtk+)
	result := C.gtk_init_with_args(nil, nil, nil, nil, nil, &err)
	if result == C.FALSE {
		return fmt.Errorf("error actually initilaizing GTK+: %s", fromgstr(err.message))
	}
	return nil
}
