Flex 画线的方法
public var lines1 :flash.display.Sprite = new Sprite (); //
lines1.graphics.lineStyle(2,0x0099ff,1);//设置颜色 粗细
lines1.graphics.moveTo(uFrom.x+uFrom.width/2,uFrom.y+uFrom.height/2); //从某个坐标开始
lines1.graphics.lineTo(uTo.x+uTo.width/2,uTo.y+uTo.height/2); //画到某个坐标
//因为addChild方法 不能识别 非继承mc.core.UIComponent的控件 所以先声明一个组件 把控件放进去然后在放进界面中
var comp: UIComponent = new UIComponent();
comp.addChild(lines);
addChild(comp);
再flex 3 IDE Flex Builder 3 beta 3下编译通过
