些ToolTip类确实比之前的方便多了,收藏
///////////////////////////------------------本文来自http://www.klstudio.com/post/198.html
这次做公司一个项目,发现原来的那个ToolTip类 使用起来还是不方便,故我又重新写一个更方便更灵活的ToolTip类,现在把相关源代码也公布出来。
新ToolTip类
- package project.do93.pflip.view
- {
- import flash.accessibility.AccessibilityProperties;
- import flash.display.*;
- import flash.events.*;
- import flash.geom.Point;
- import flash.text.*;
- /**

- public class ToolTip extends Sprite {
- private static var instance:ToolTip = null ;
- private var label:TextField;
- private var area:DisplayObject;
- public function ToolTip() {
- label = new TextField();
- label.autoSize = TextFieldAutoSize.LEFT;
- label.selectable = false ;
- label.multiline = false ;
- label.wordWrap = false ;
- label.defaultTextFormat = new TextFormat( "宋体" , 12 , 0x666666 );
- label.text = "提示信息" ;
- label.x = 5 ;
- label.y = 2 ;
- addChild(label);
- redraw();
- visible = false ;
- mouseEnabled = mouseChildren = false ;
- }
- private function redraw() {
- var w:Number = 10 + label.width;
- var h:Number = 4 + label.height;
- this .graphics.clear();
- this .graphics.beginFill( 0x000000 , 0.4 );
- this .graphics.drawRoundRect( 3 , 3 , w, h, 5 , 5 );
- this .graphics.moveTo( 6 , 3 + h);
- this .graphics.lineTo( 12 , 3 + h);
- this .graphics.lineTo( 9 , 8 + h);
- this .graphics.lineTo( 6 , 3 + h);
- this .graphics.endFill();
- this .graphics.beginFill( 0xffffff );
- this .graphics.drawRoundRect( 0 , 0 , w, h, 5 , 5 );
- this .graphics.moveTo( 3 , h);
- this .graphics.lineTo( 9 , h);
- this .graphics.lineTo( 6 , 5 + h);
- this .graphics.lineTo( 3 , h);
- this .graphics.endFill();
- }
- public static function init(base:DisplayObjectContainer) {
- if (instance == null ) {
- instance = new ToolTip();
- base.addChild(instance);
- }
- }
- public static function register(area:DisplayObject, message:String): void {
- if (instance != null ){
- var prop:AccessibilityProperties = new AccessibilityProperties();
- prop.description = message;
- area.accessibilityProperties = prop;
- area.addEventListener(MouseEvent.MOUSE_OVER, instance.handler);
- }
- }
- public static function unregister(area:DisplayObject): void {
- if (instance != null ) {
- area.removeEventListener(MouseEvent.MOUSE_OVER, instance.handler);
- }
- }
- public function show(area:DisplayObject): void {
- this .area = area;
- this .area.addEventListener(MouseEvent.MOUSE_OUT, this .handler);
- this .area.addEventListener(MouseEvent.MOUSE_MOVE, this .handler);
- label.text = area.accessibilityProperties.description;
- redraw();
- }
- public function hide(): void {
- this .area.removeEventListener(MouseEvent.MOUSE_OUT, this .handler);
- this .area.removeEventListener(MouseEvent.MOUSE_MOVE, this .handler);
- this .area = null ;
- visible = false ;
- }
- public function move(point:Point): void {
- var lp:Point = this .parent.globalToLocal(point);
- this .x = lp.x - 6 ;
- this .y = lp.y - label.height - 12 ;
- if (!visible){
- visible = true ;
- }
- }
- private function handler(event:MouseEvent): void {
- switch (event.type) {
- case MouseEvent.MOUSE_OUT:
- this .hide();
- break ;
- case MouseEvent.MOUSE_MOVE:
- this .move( new Point(event.stageX, event.stageY));
- break ;
- case MouseEvent.MOUSE_OVER:
- this .show(event.target as DisplayObject);
- this .move( new Point(event.stageX, event.stageY))
- break ;
- }
- }
- }
- }
调用实例
- import project.do93.pflip.view.ToolTip;
- var base:Sprite = new Sprite();
- addChild(base);
- var sp:Sprite = new Sprite();
- sp.mouseEnabled=sp.mouseChildren= false ;
- addChild(sp);
- //初始化ToolTip;
- ToolTip.init(sp);
- //与显示元素关联。
- ToolTip.register(xxx_mc, "http://www.klstudio.com" );
- ToolTip.register(btn1, "我是按钮1" );
- ToolTip.register(btn2, "我是按钮2" );
