Golang KeyPress.Shift Examples

Example #1

File: main.go Project: hanshenu/lime

// key HandleFunc for the http /key endpoint. This only happens if the client
// doesn't support websockets.
func (t *tbfe) key(w http.ResponseWriter, req *http.Request) {
	log.Debug("key: %s", req)
	kc := req.FormValue("keyCode")
	var kp keys.KeyPress
	v, _ := strconv.ParseInt(kc, 10, 32)

	if req.FormValue("altKey") == "true" {
		kp.Alt = true
	}
	if req.FormValue("ctrlKey") == "true" {
		kp.Ctrl = true
	}
	if req.FormValue("metaKey") == "true" {
		kp.Super = true
	}
	if req.FormValue("shiftKey") == "true" {
