如何从 file2.as 调用 file1.as 中的函数？
这是代码。
package com.modestmaps
{
import com.modestmaps.overlays.MarkerClip;
import flash.display.Graphics;
import flash.display.Loader;
import flash.display.Shape;
import flash.display.Sprite;
import flash.filters.BlurFilter;
import flash.geom.Matrix;
import flash.geom.Rectangle;
import flash.net.URLRequest;
import flash.text.TextField;
//import mx.core.Application;
import mx.core.Application;
import flash.events.MouseEvent;
public class InfoBubble extends Sprite
{
private var btn_close:String = "http://(.yada.yada.)/media/close_button.swf";
public var textField:TextField;
public var background:Shape;
public var shadow:Shape;
public var infoClip:MarkerClip;
protected var map:InfoMap;
//var infoClip:MarkerClip;
public var infoBubble:InfoBubble;
public function InfoBubble(urlLink:String)
{
//the name of my markers are set to the links of the swf files in which I want to load into the infobubble
this.name = urlLink;
this.mouseEnabled = false;
this.mouseChildren = true;
this.buttonMode=false;
shadow = new Shape();
shadow.filters = [ new BlurFilter(16, 16) ];
shadow.transform.matrix = new Matrix(1, 0, -0.5, 0.5, 0, 0);
addChild(shadow);
background = new Shape();
addChild(background);
textField = new TextField();
textField.selectable = false;
//the infobubble is still sized according to the textField.width and height
//I don't know how to get the size of the loaded swf
textField.width = textField.textWidth+432+4;
textField.height = textField.textHeight+288+4;
//add main swf
var request:URLRequest = new URLRequest(urlLink);
var loader:Loader = new Loader();
loader.load(request);
addChild(loader);
//position the main swf
//current measurements of swf file w432 h288
loader.y = -288 - 37;
loader.x = mx.core.FlexGlobals.topLevelApplication.LBloaderX;
//add close button
var reqButton:URLRequest = new URLRequest(btn_close);
var loader2:Loader = new Loader();
loader2.load(reqButton);
addChild(loader2);
loader2.addEventListener(MouseEvent.CLICK, closeInfoBubble);
function closeInfoBubble(event:MouseEvent):void
{
infoClip.removeMarkerObject(infoBubble)
infoBubble = null
}
//position the closebutton swf
//current measurements of closebutton swf file w18 h18
loader2.y = -286 - 37;
loader2.x = mx.core.FlexGlobals.topLevelApplication.LBloader2X;
// remember that things in marker clips are positioned with (0,0) at the given location
textField.y = -textField.height - 35;
textField.x = -10;
//I need to find out how to detect the width and height of the swf file loaded into loader2
//instead of the size of the textField
var rect:Rectangle = textField.getRect(this);
// get your graph paper ready, here's a "speech bubble"
background.graphics.beginFill(0x12345);
shadow.graphics.beginFill(0x000000);
for each (var g:Graphics in [ background.graphics, shadow.graphics ] ) {
g.moveTo(rect.left, rect.top);
g.lineTo(rect.right, rect.top);
g.lineTo(rect.right, rect.bottom);
g.lineTo(rect.left+15, rect.bottom);
g.lineTo(rect.left+10, rect.bottom+15);
g.lineTo(rect.left+5, rect.bottom);
g.lineTo(rect.left, rect.bottom);
g.lineTo(rect.left, rect.top);
g.endFill();
}
}
}
}
在这个包中，我试图添加阴影，它可以工作，然后添加信息气泡，它可以工作，然后添加一个可以工作的主 swf，然后添加一个 close_button.swf 它确实加载了 swf；但是，当我尝试添加侦听器时，我无法使信息气泡关闭。
