Flex3学习轨迹：显示简单的动态鼠标

当鼠标移动到Panel容器的上方的时候，出发了MouseOver事件，然后利用CursorManager类的setCursor()方法来设置鼠标指针。分别显示圆形、矩形、椭圆形、圆边矩形的类。这些类必须继承自flash.display.Sprite基类。绘制圆形的AS代码：

package cursors{import flash.display.Sprite;public class Circle extends Sprite{public function Circle(){this.graphics.lineStyle( 1 , 0x000000 , 1 );this.graphics.drawCircle( 0 , 0 , 10 );super();}}}

绘制椭圆形：

package cursors{import flash.display.Sprite;public class Ellipse extends Sprite{public function Ellipse(){this.graphics.lineStyle( 1 , 0x000000 , 1 );this.graphics.drawEllipse( 0 , 0 , 50 , 10 );super();}}}

绘制矩形：

package cursors{import flash.display.Sprite;public class Rect extends Sprite{public function Rect(){this.graphics.lineStyle( 1 , 0x000000 , 1 );this.graphics.drawRect( 0 , 0 , 40 , 15);super();}}}

绘制圆边矩形：

package cursors{import flash.display.Sprite;public class RoundRectComplex extends Sprite{public function RoundRectComplex(){this.graphics.lineStyle( 1 , 0x000000 , 1 );this.graphics.drawRoundRectComplex( 0 , 0 , 45 , 25 , 5 , 0 , 0 , 5 );super();}}}
