Using the UILoader

The UILoader component is a container that can display SWF, JPEG, progressive JPEG, PNG, and GIF files. You can use a UILoader whenever you need to retrieve content from a remote location and pull it into a Flash application. For example, you could use a UILoader to add a company logo (JPEG file) to a form. You could also use the UILoader component in an application that displays photos. Use the load() method to load content, the percentLoaded property to determine how much content has loaded, and the complete event to determine when loading is finished.

You can scale the contents of the UILoader or resize the UILoader itself to accommodate the size of the contents. By default, the contents are scaled to fit the UILoader. You can also load content at run time and monitor loading progress (although after content has been loaded once it is cached, the progress jumps to 100% quickly). If you specify a location when loading content in the UILoader, you must specify the location (X and Y coordinates) as 0, 0.
