capabilities (System.capabilities) class 23
capabilities (System.capabilities) class
The System.capabilities class determines the abilities of the system and player hosting a SWF
file, which lets you tailor content for different formats. For example, the screen of a cell phone
(black and white, 100 square pixels) is different than the 1000-square-pixel color PC screen.
To provide appropriate content to as many users as possible, you can use the
System.capabilities object to determine the type of device a user has. You can then either
specify to the server to send different SWF files based on the device capabilities or tell the
SWF file to alter its presentation based on the capabilities of the device.
