关于FlexBuilder的Event注释
Categories: Flex; Tagged with: Event • Flex; @ March 15th, 2009 10:28如果某个类派发某事件， 我们通常使用如下注释：
/** * Dispatched when …. * @eventType com.events.MyEvent.EVENT_TEST */
[Event(name=”myEvent” type=”com.events.MyEvent”)]
在使用new testr().addEvent…时提示的Const是错误的.MyEvent.MY_EVENT
解决方法:
[Event(name=”eventTest” type=”com.events.myevent”)]
此时的提醒为MyEvent.EVENT_TEST
[]中的name应与Event中的const的名字 如EVENT_TEST:String = "myEvent"; 中的EVENT_TEST对应 ,’_"后的字母保留大写去掉下划线->eventTest即可.
注意: Flex框架中的事件， 其Const 与String的name都是想对应的.
==>不得不承认 这样子比较挫<==
所以在编写自定义事件时, 最好也遵守这个不成文的规定:
public static const EVENT_EO_EDITOR:String = "eventEoEditor";
而不是随便乱写一个String, 这样便于在其他派发该事件的类中编写事件注释.
FLEX Image: 显示指定的图片范围, 而非缩放图片
Categories: Flex; Tagged with: Flex • Image; @ March 15th, 2009 10:15 
第一副图截取该图片靠左上的５００＊６５
第二幅图则将图片转换为５００＊６５
Image的scaleContent默认为true,将其置为false, 则实现第一附图的效果.
private function setImgVisable(visable:Boolean, source:String=null):void {
_imgBanner.visible = visable;
if(visable) {
_imgBanner.scaleContent = false;
_imgBanner.explicitHeight = IMG_HEIGHT;
_imgBanner.explicitWidth = IMG_WEIHT;
_imgBanner.source = source;
}else {
_imgBanner.explicitHeight = 0;
_imgBanner.explicitWidth = 0;
_imgBanner.source = null;
}
}
Flex Tree样式: 如何修改Tree的Icon
Categories: Flex; Tagged with: ActionScript • Flex • Icon • Tree; @ March 12th, 2009 10:50
可以通过设定Tree的样式来更改Tree的icon. 如下
_treeLAAndSub = new Tree();
_treeLAAndSub.iconField = "hahah@#$@#$";
_treeLAAndSub.setStyle("folderClosedIcon", ImagesForActions.iconImport); //文件夹关闭时
_treeLAAndSub.setStyle("folderOpenIcon", ImagesForActions.iconExport); //文件夹打开
_treeLAAndSub.setStyle("defaultLeafIcon", ImagesForActions.iconCopy); // 叶子
_treeLAAndSub.setStyle("disclosureOpenIcon", ImagesForActions.iconRemove); //文件夹打开时旁边的图示
_treeLAAndSub.setStyle("disclosureClosedIcon", ImagesForActions.iconAdd); //文件夹关闭时旁边的图示
