FlexPrintJob: A class that prints one or more objects. Automatically splits large objects for printing on multiple pages and scales the output to fit the page size. PrintDataGrid A subclass of the DataGrid control with a default appearance that is customized for printing. The class includes properties and a method that provide additional sizing and printing features. PrintAdvancedDataGrid A subclass of the AdvancedDataGrid control with a default appearance that is customized for printing. The class includes properties and a method that provide additional sizing and printing features. PrintOLAPDataGrid A subclass of the OLAPDataGrid control with a default appearance that is customized for printing. The class includes properties and a method that provide additional sizing and printing features. FlexPrintJobScaleType Defines constants used in the FlexPrintJob addObject() method. Together, these classes give you control over how the user prints information from the application. For example, your application can print only a selected subset of the information on the screen, or it can print information that is not being displayed. Also, your application can reformat the information and optimize its layout and appearance for printing.
Modules are SWF files that can be loaded and unloaded by an application. They cannot be run independently of an application, but any number of applications can share the modules. Modules let you split your application into several pieces, or modules. The main application, or shell, can dynamically load other modules that it requires, when it needs them. It does not have to load all modules when it starts, nor does it have to load any modules if the user does not interact with them. When the application no longer needs a module, it can unload the module to free up memory and resources. Modular applications have the following benefits:
Smaller initial download size of the SWF file.
Shorter load time due to smaller SWF file size.
Better encapsulation of related aspects of an application.
One of the benefits of a Flex application is that the application can smoothly transition from state to state without having to fetch a new page from the server and refresh the browser. By avoiding the constant refreshing of pages, the end-user's experience is more fluid and continuous. In addition, the load on the server is greatly reduced because it need only return the application once, rather than a new page every time the user changes views.
