flex 动画笔记

1、不涉及到组件宽度和高度变化的

如果类似showEffect等属性不好使的，直接使用hideEffect.end(); showEffect.play();等这样的用法。

2、涉及到组件宽度和高度变化的

在执行动画期间，需要把显示区域的visible设置成false。

        <s:Parallel  duration="500" id="showEffect" target="{window}" effectEnd="sEffectEnd()">
            <s:children>
                <s:Move xFrom="{FlexGlobals.topLevelApplication.width-50}"  yFrom="50"
                        xTo="{FlexGlobals.topLevelApplication.width/2-375}" yTo="{FlexGlobals.topLevelApplication.height/2-275}" />
                <s:Resize  widthFrom="0" widthTo="750" heightFrom="0" heightTo="550"/>
            </s:children>
        </s:Parallel>
        <s:Parallel duration="500" id="hideEffect" target="{window}"  effectEnd="hEffectEnd()">
            <s:children>
                <s:Move  xTo="{FlexGlobals.topLevelApplication.width-50}" yTo="50" />
                <s:Resize  widthTo="0" heightTo="0"/>
            </s:children>
        </s:Parallel>

            protected function basewidget1_creationCompleteHandler():void
            {
                content.visible=false;
                hideEffect.end();
                showEffect.play();
            }
            private function sEffectEnd():void
            {
                content.visible=true;
            }
            private function hEffectEnd():void
            {
                PopUpManager.removePopUp(window);
                AppEvent.dispatch(AppEvent.WIDGET_CLOSE,widgetId);
            }
            private function closeHandler():void
            {
                content.visible=false;
                showEffect.end();
                hideEffect.play();
            }
