铺满浏览器屏幕的Flash可以通过设置引用Flash参数中的width和height为100%来实现. 但是,光做这点是不够的,原因是Flash的内部的界面部局,尚没有如此智能(指的是非FLEX PROJECT,如ActionScript Project或用Flash IDE编译的项目等). 今天,用户的浏览器分辨率主要为1024*768和1280*1024,还有一些老外用那种非常宽大的浏览器:

想让你的Flash应用在诸多用户面前都有一个比较好的页面展现,就需要一些代码来辅助了.
注意到AS3中有一个Event.RESIZE事件,此事件当Flash的大小发生改变时激发...AHA,找到答案了;)
看一下实现的代码,以下代码写在主类中:
//4.init screen size adjust
private function initScreenAdjust():void
{
//Set Scale Mode,设定缩放模式为无缩放
stage.scaleMode=StageScaleMode.NO_SCALE;
//Set Screen adjust event,设置屏幕缩放
stage.addEventListener(Event.RESIZE,screenAdjust);
//在程序初始时就调用一下界面调整
screenAdjust(null);
}
//4.1Adjust Sample实例
private function screenAdjust(evt:Event):void
{
//UIData.SCREEN_WIDTH和UIData.SCREEN_HEIGHT指的是编译出的Flash宽高值.
//可通过[SWF(width="1024",height="768"]的形式进行设定(FLEX),或在FLASH IDE中直接设定
var offX:int=Math.floor((UIData.SCREEN_WIDTH -stage.stageWidth)/2);
var offY:int=Math.floor((UIData.SCREEN_HEIGHT-stage.stageHeight)/2);
//this指的是主类,这样做的原因请参考图2
this.x=offX;
this.y=offY;
//内部UI调整,这里调整的是下部工具栏的一个Y值.
mDownToolBar.y =stage.stageHeight-UIData.DOWN_BAR_OFF_Y;
}
图2展示的是Flash主类的坐标值与stage宽高的关系,这里的调整是将Flash主类的左上角始终贴齐当前Flash Player的左上角,无论尺寸如何变化.

其实,我这里只是给出一种界面调整方案而已,有时,你可能希望主类局中,一切就看你的需要喽.
一个简单的示例程序地址,可以通过调整浏览器的大小来观察界面的布局改变:Video始终居中;上,下工具栏分别位于上下两边,(代码很容易,主要的上面都已经贴了,就不附代码了)

贴一个实际的应用吧,我的六度拓扑在不同浏览器下的表现,广告广告;)

MySQL is suitable for beginners to learn database skills. 1. Install MySQL server and client tools. 2. Understand basic SQL queries, such as SELECT. 3. Master data operations: create tables, insert, update, and delete data. 4. Learn advanced skills: subquery and window functions. 5. Debugging and optimization: Check syntax, use indexes, avoid SELECT*, and use LIMIT.

MySQL efficiently manages structured data through table structure and SQL query, and implements inter-table relationships through foreign keys. 1. Define the data format and type when creating a table. 2. Use foreign keys to establish relationships between tables. 3. Improve performance through indexing and query optimization. 4. Regularly backup and monitor databases to ensure data security and performance optimization.

MySQL is an open source relational database management system that is widely used in Web development. Its key features include: 1. Supports multiple storage engines, such as InnoDB and MyISAM, suitable for different scenarios; 2. Provides master-slave replication functions to facilitate load balancing and data backup; 3. Improve query efficiency through query optimization and index use.

SQL is used to interact with MySQL database to realize data addition, deletion, modification, inspection and database design. 1) SQL performs data operations through SELECT, INSERT, UPDATE, DELETE statements; 2) Use CREATE, ALTER, DROP statements for database design and management; 3) Complex queries and data analysis are implemented through SQL to improve business decision-making efficiency.

The basic operations of MySQL include creating databases, tables, and using SQL to perform CRUD operations on data. 1. Create a database: CREATEDATABASEmy_first_db; 2. Create a table: CREATETABLEbooks(idINTAUTO_INCREMENTPRIMARYKEY, titleVARCHAR(100)NOTNULL, authorVARCHAR(100)NOTNULL, published_yearINT); 3. Insert data: INSERTINTObooks(title, author, published_year)VA

The main role of MySQL in web applications is to store and manage data. 1.MySQL efficiently processes user information, product catalogs, transaction records and other data. 2. Through SQL query, developers can extract information from the database to generate dynamic content. 3.MySQL works based on the client-server model to ensure acceptable query speed.

The steps to build a MySQL database include: 1. Create a database and table, 2. Insert data, and 3. Conduct queries. First, use the CREATEDATABASE and CREATETABLE statements to create the database and table, then use the INSERTINTO statement to insert the data, and finally use the SELECT statement to query the data.

MySQL is suitable for beginners because it is easy to use and powerful. 1.MySQL is a relational database, and uses SQL for CRUD operations. 2. It is simple to install and requires the root user password to be configured. 3. Use INSERT, UPDATE, DELETE, and SELECT to perform data operations. 4. ORDERBY, WHERE and JOIN can be used for complex queries. 5. Debugging requires checking the syntax and use EXPLAIN to analyze the query. 6. Optimization suggestions include using indexes, choosing the right data type and good programming habits.
