我已经创建了一个Flash Builder ActionScript 3的项目,它加载包含ComboBox组件这是在闪存CS5创建的外部SWF。
I've created a flash builder actionscript 3 project which loads an external swf which was created in flash cs5 which contains the combobox component.
我如何动态地添加的项目呢?
How do i dynamically add items to it?
mc1['itemList'].addItem({label:"test"});
似乎并没有工作?
does not seem to work??
如果你想在运行时可以使用getChildByName方法加载的SWF中访问实例
if you want to access instances within a swf loaded at runtime you can use the getChildByName method
Object(MovieClip(__loader.content).getChildByName('itemList'))
我测试了它使用下面的code,它工作正常。我创建了一个包含两个组合框一个小的Flash CS5文件。第二个是展示如何实例加载的SWF中定义的类。
I tested it using the following code, it works fine. I created a small Flash CS5 File containing two ComboBoxes. The second one is to demonstrate how to instantiate a class defined within the loaded swf.
