Object: GUITouch

觸摸事件返回的數(shù)據(jù)結(jié)構(gòu), 這是個Object類型描述并沒有實(shí)際存在的構(gòu)造函數(shù)

GUITouch.id

• {uint}

GUITouch.startX

• {float}

GUITouch.startY

• {float}

GUITouch.x

• {float}

GUITouch.y

• {float}

Class: Notification

這是事件EventNoticer的集合，事件觸發(fā)與響應(yīng)中心

繼承于它的派生類型可以使用event關(guān)鍵字來聲明成員事件

Notification.trigger(name[,data])

通過事件名稱觸發(fā)事件 --> EventNoticer.trigger(data)

Notification.triggerWithEvent(name,event)

通過名稱與Event觸發(fā)事件 --> EventNoticer.triggerWithEvent(event)

allNoticers(notification)

獲取notification上的所有EventNoticer

• @arg notification {Notification}
• @ret {Array} 返回內(nèi)容為EventNoticer的Array

removeEventListenerWithScope(notification,scope)

卸載notification上所有與scope相關(guān)的偵聽器

實(shí)際上遍歷調(diào)用了EventNoticer.off(scope)方法

• @arg notification {Notification}
• @arg scope {Object}

Example:

class TestNotification extends Notification {
    eventonChange; // 這里必須以on開始以;分號結(jié)束
}


var notification = new TestNotification();
// Prints: responseonChange 0 100
notification.onChange = function(ev) { // add default listener
    console.log('responseonChange 0', ev.data)
}
notification.triggerChange(100);


// Prints: 
// responseonChange 0 200
// responseonChange 1
notification.onChange.on(function(ev) {
    console.log('responseonChange 1')   
})
notification.triggerWithEvent('change', new Event(200));


var noticer = notification.onChange;
noticer.off(0) // delete default listener
// Prints: responseonChange 1
notification.triggerChange();

Class: EventNoticer

• @arg sender {Object}

EventNoticer.enable

事件是否啟用,noticer.enable=false可禁用事件的發(fā)送,Default true

• {bool}

• {String}

Get: EventNoticer.sender

返回初始化時的sender對像

• {Object}

Get: EventNoticer.length

監(jiān)聽器數(shù)量

• {uint}

EventNoticer.on(listen[,scope[,id]])

添加監(jiān)聽器函數(shù),并指定scopethis

• @arg func {Function} 監(jiān)聽器函數(shù)
• @arg [scope] {Object} 范圍this對像
• @arg [id] {int} 指定一個id,如果不指定自動生成一個,如果指定的id已經(jīng)存在會替換之前的監(jiān)聽器
• @ret {int} return id 返回傳入的id或自動生成的id

Example:

var scope = { a:100 }
var id = display_port.onChange.on(function(ev) {
// Prints: 100
    console.log(this.a)
}, scope)
// 替換監(jiān)聽器
display_port.onChange.on(function(ev) {
// Prints: replace 100
    console.log('replace', this.a)
}, scope, id)

EventNoticer.once(listen[,scope[,id]])

添加監(jiān)聽器函數(shù),并指定scopethis,只監(jiān)聽一次

EventNoticer.on2(listen[,scope[,id]])

添加監(jiān)聽器函數(shù),并指定scopethis,與on()僅回調(diào)參數(shù)不相同

Example:

var scope = { a:100 }
var id = display_port.onChange.on2(function(scope, ev) {
// Prints: 100
    console.log(scope.a)
}, scope)

EventNoticer.once2(listen[,scope[,id]])

添加監(jiān)聽器函數(shù),并指定scopethis,只監(jiān)聽一次
