1.toolTip换行符
<mx:Button id="btn1" toolTip="在工具条提示中 使用换行符"/>
2.设定工具条提示的样式
[javascript] view plaincopy
- <mx:Style>
- ToolTip
- {
- fontSize:19;
- color:#FF6699;
- }
- </mx:Style>
3.设定工具提示宽度
[javascript] view plaincopy
- <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" creationComplete="init()">
- <mx:Script>
- <![CDATA[
- import mx.controls.ToolTip;
- public function init():void
- {
- ToolTip.maxWidth=100;
- }
- ]]>
- </mx:Script>
4.使用工具条提示事件
toolTipCrate
toolTipEnd
toolTipHide
toolTipShow
toolTipShown
toolTipStart
[javascript] view plaincopy
- <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" creationComplete="init()">
- <mx:Script>
- <![CDATA[
- import mx.events.ToolTipEvent;
- import flash.media.Sound;
- [Embed(source="demo.mp3")]
- private var beepSound:Class;
- private var myClip:Sound;
- public function init():void
- {
- TooTip.maxWidth=100;
- }
- public function playSoune():void
- {
- myClip.play();
- }
- public function myListener(event:ToolTipEvent):void
- {
- playSoune();
- }
- public function init():void
- {
- lbl.addEventListener(ToolTipEvent.TOOL_TIP_SHOW,myListener);
- myClip=new beepSound();
- }
- ]]>
- </mx:Script>
- <mx:Label id="lbl" toolTip="demo ToolTip" text="mouse over here" />
5.ToolTip Manager
ToolTip Manager 类用来管理toolTip属性,包含在mx.managers包中
使用ToolTip Manager 延迟工具条显示的时间,在工具条上使用行为效果
建立动态的工具条提示,使用自定义的工具条提示
公共属性
currentTarget : DisplayObject
当前显示工具提示的 UIComponent;如果未显示工具提示,则为 null。 ToolTipManager
currentToolTip : IToolTip
当前可见的 ToolTip 对象;如果未显示 ToolTip 对象,则为 null。 ToolTipManager
enabled : Boolean
如果为 true,则当用户将鼠标指针移至组件上方时,ToolTipManager 会自动显示工具提示。 ToolTipManager
hideDelay : Number
自工具提示出现时起,Flex 要隐藏此提示前所需等待的时间量(以毫秒为单位)。 ToolTipManager
hideEffect : IAbstractEffect
隐藏工具提示时播放的效果;如果工具提示在消失时不应显示任何效果,则为 null。 ToolTipManager
prototype : Object
对类或函数对象的原型对象的引用。 Object
scrubDelay : Number
在 Flex 再次等待 showDelay 持续显示工具提示之前,用户在各控件间移动鼠标时可以花费的时间(以毫秒为单位)。 ToolTipManager
showDelay : Number
当用户将鼠标移至具有工具提示的组件上方时,Flex 等待 ToolTip 框出现所需的时间(以毫秒为单位)。 ToolTipManager
showEffect : IAbstractEffect
显示工具提示时播放的效果;如果工具提示在显示时不应显示任何效果,则为 null。 ToolTipManager
toolTipClass : Class
创建工具提示要用到的类。
1.控制工具条的显示隐藏
ToolTip Manager enabled属性来定义工具条提示状态,默认为true,设定为false就表示禁用
2.延迟工具条的提示时间
showDelay 默认为500毫秒 当鼠标在控件之间移动时,flex等待显示工具条提示的时间长度
hideDelay 默认值为10000毫秒 如果设定hideDelay属性值为0,flex不显示工具条提示,如果设定为Infinity,flex则一致显示工具提示
直到下一个动作,或者鼠标离开主键
例如:
ToolTipManager.showDelay=0;//立即显示
ToolTipManager.hideDelay=3000;//3s秒后隐藏
3.在工具条上使用动画效果
[javascript] view plaincopy
- <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" creationComplete="init()">
- <mx:Script>
- <![CDATA[
- import mx.managers.ToolTipManager;
- import mx.events.ToolTipEvent;
- import flash.media.Sound;
- [Embed(source="demo.mp3")]
- private var beepSound:Class;
- private var myClip:Sound;
- public function init():void
- {
- TooTip.maxWidth=100;
- ToolTipManager.showEffect=fadeIn;
- }
- ]]>
- </mx:Script>
- <mx:Label id="lbl" toolTip="demo ToolTip" text="mouse over here" />
- <mx:Fade id="fadeIn" alphaFrom="0" alphaTo="1" duration="1000" />
- <mx:Panel >
- <mx:Button id="btn" toolTip="demoasdf" />
- </mx:Panel >
4.建立动态工具条体提示
ToolTipManager有两种方法,即:createToolTip()和destroyToolTip()
建立一个工具条提示对象时,可以定义其属性,样式,事件和效果。
crateToolTip()方法结构
createToolTip(text:String, x:Number, y:Number, errorTipBorderStyle:String = null, context:IUIComponent = null):IToolTip
[] 使用指定的文本创建 ToolTip 类的实例,然后在舞台坐标中的指定位置显示此实例。 ToolTipManager
destroyToolTip(toolTip:IToolTip):void
[] 销毁由 createToolTip() 方法创建的指定 ToolTip。
例如:
<mx:Label id="lbl" toolTip="demo ToolTip" text="mouse over here" />
<mx:Button id="btn1" toolTip="填写的是{lbl.text}"/>
5.建立用户自定义的工具条提示
- <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" >
- <mx:Script>
- <![CDATA[
- import mx.managers.ToolTipManager;
- import mx.events.ToolTip;
- public var myTip:ToolTip;
- public function init():void
- {
- var s:String ="保存,应用,退出";
- myTip=ToolTipManager.createToolTip(s,10,10) as ToolTip;
- myTip.setStyle("backgroundColor",0xFFCC00);
- myTip.width=300;
- myTip.height=40;
- }
- public funciton destroyBigTip():void
- {
- ToolTipManager.destroyToolTip(myTip);
- }
- ]]>
- </mx:Script>
- <mx:Button id="btn" toolTip="test toolTip" rollOver="init()" rollOut="destroyBigTip()"/>
6.使用错误信息提示工具条
As代码
- <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" >
- <mx:Script>
- <![CDATA[
- import mx.managers.ToolTipManager;
- import mx.events.ToolTip;
- public var errorTip:ToolTip;
- private function validatefun(type:String,event:Object):void
- {
- errorTip=" demo test ";
- errorTip=ToolTipManager.createToolTip(errorTip,event.currentTarget.x,event.currentTarget.y) as ToolTip;
- errorTip.setStyle("styleName","errorTip");
- }
- <mx:TextInput id="txt" enter="validatefun(‘demo‘,event)" />
7.重写工具条皮肤
ToolTip皮肤存在mx.skins.ToolTipBorder.as文件中
当然需要重写的时候就可以 ToolTipBorder 类继承的类就可以了
例如:
Java代码
- package
- {
- import mx.skins.RectangularBorder;
- public class MyToolTipBorder extends RectangularBorder
- {
- public function MyToolTipBorder()
- {
- super();
- }
- override protected function updateDisplayList(unscaledWidth:Number,
- unscaledHeight:Number):void
- {
- }
- override public function layoutBackgroundImage():void {
- }
- }
- }mxml中使用
- <mx:Style>
- ToolTip
- {
- borderSkin:ClassReference("MyToolTipBorder");
- }
- </mx:Style>

附件为源文件
1. 设置ToolTip风格(通过css来设置)
ToolTip {
fontFamily: "Arial";
fontSize: 13;
fontStyle: "italic";
color: #FF6699;
backgroundColor: #33CC99;
}
当然这个可以通过css来动态设置例如:
StyleManager.getStyleDeclaration("ToolTip").setStyle("fontStyle","italic");
2. 错误提示errotTip
errorTip
{
border-style:"errorTipRight";
}
其中border-style其对应的格式决定小三角的方位,可选值:[toolTip,errorTipRight,errorTipAbove,errorTipBelow]
<mx:TextInput x="85" y="118" text="021-阿萨德发送" errorString="输入有误!" />
如果想修改源码,改变小三角的大小或者位置的话就需要自定义border-skin
ToolTip
{
border-skin:ClassReference("com.MyToolTipBorder");
}
其中 com.MyToolTipBorder其中是一个继承了RectangularBorder的类,源码参见附件, ToolTip默认的skin-class路径在sdk
sdks\3.0.0\frameworks\projects\framework\src\mx\skins\halo\ToolTipBorder
引入包的路径:import mx.skins.halo.ToolTipBorder;
笔者发现 ToolTipBorder 的类对于4个方向支持不是很好,其中最右边的提示,也就是小三角在右边的没有,把源码修改了下(附件中有MyToolTipBorder)
改变默认的错误提示的背景色设置4个方向的提示
3. 使用ToolTipManager动态创建自定义的tooltip;
使用ToolTipManager管理器类能够让你设置基本的ToolTip功能。比如显示延迟,以及控制是否显示ToolTip信息内容。
你可以在程序中激活和停止使用ToolTips.
可以使用enabled这个属性来激活或者停止使用ToolTips,如果停止使用,在鼠标移到到组件上方的时候就不会用ToolTips的框显示出来,不管那个组件是否设置了toolTip这个属性值
设置ToolTipManager的常用属性介绍
ToolTipManager.enabled = true;//鼠标移入控件自动显示工具提示
ToolTipManager.showDelay = 0; //flex 等待tooltip出现的时间单位毫秒默认500
ToolTipManager. hideDelay=3000; //flex 隐藏tooltip所需的事件等待量 单位毫秒,默认500
ToolTipManager.showEffect= fadeIn; //显示tooltip的特效
ToolTipManager. hideEffect= fadeIn; //隐藏 tooltip的特效
<mx:Fade id="fadeIn" alphaFrom="0" alphaTo="1" duration="1000"/>
4. 使用ToolTipManager createToolTip,destroyToolTip来动态创建自定义tooltip
一般自定义tooltip都是在控件的
MouseEvent. ROLL_OVER(rollOver)
MouseEvent. MOUSE_OVER (mouseOver)
控制自定义tooltip的显示
MouseEvent. ROLL_OUT (rollOut)
MouseEvent. MOUSE_OUT (mouseOut)
控制自定义tooltip的隐藏
现已rollOver结合ToolTipManager实现自定义tooltip
Xml代码
- <mx:Script>
- <![CDATA[
- import mx.managers.ToolTipManager;
- public var myTip:ToolTip;
- private function showTip(event:MouseEvent,type:String):void
- {
- Tip=ToolTipManager.createToolTip(str,event.stageX,event.stageY) as ToolTip;
- //根据需要动态设置tooltip的style属性
- myTip.move(event.stageX,event.stageY);
- }
- private function hideTip():void
- {
- ToolTipManager.destroyToolTip(myTip);
- }
- ]]>
- </mx:Script>
5. 实现mx.core.IToolTip接口自定义toolTip的外观(可选as实现该接口,mxml实现该接口)
现已mxml实现该接口为例(简单), MyPanelToolTip.mxml
Xml代码
- <mx:Panel xmlns:mx="http://www.adobe.com/2006/mxml"
- implements="mx.core.IToolTip"
- width="212"
- borderThickness="2"
- backgroundColor="0xCCCCCC"
- dropShadowEnabled="true"
- borderColor="black"
- roundedBottomCorners="true"
- height="90">
- <mx:Script>
- <![CDATA[
- //注意 Panel 中的 implements="mx.core.IToolTip"
- [Bindable]
- private var _text:String="";
- public function get text():String {
- return _text ;
- }
- public function set text(value:String):void {
- this._text=value;
- }
- ]]></mx:Script>
- <mx:Text text="{text}" percentWidth="100"/>
- </mx:Panel>
使用时:
private function createCustomTip(title:String, body:String, event:ToolTipEvent):void
{
var pan:MyPanelToolTip = new MyPanelToolTip();
pan.title = title;
pan.text=body;
event.toolTip = pan;
}
<mx:Button id="btn3" label="button" x="275.5" toolTip="demo" toolTipCreate="createCustomTip(‘自定义tooltip‘,‘该tooltip实现mx.core.IToolTip接口,注意是控件必须设置toolTip属性的值‘,event)" y="187"/>
6. 自定义组件(继承UIComponent)结合mouseover事件形式
效果图:

flex中toolTip汇总 转
