BrightSign players use a standardized library of BrightScript objects to expose functionality for software development. To publish a new API for interacting with BrightSign hardware, we create a new BrightScript object. Insert excerpt BrightScript Version Navigation Menu BrightScript Version Navigation Menu nopanel true
The pages in this section provide definitions for objects that can be used in BrightScript. A brief description, a list of interfaces, and the member functions of the interfaces are provided for each object class. While most BrightScript objects have self-contained pages, some objects are grouped on the same page if they are closely related or depend on one another for functionality.
Here is a sample of objects that are used frequently when creating applications in BrightScript:
| roVideoMode | Configures video output and interacts with displays using CEC/EDID. |
| roRectangle | Used to define zones/widgets on the screen. This object is passed to many other objects to define their screen area, including roVideoPlayer, roImagePlayer, roImageWidget, roHtmlWidget, roClockWidget, and roCanvasWidget. |
| roVideoPlayer | Plays video files, streams, and HDMI® input. |
| roImagePlayer | Displays images. |
| roHtmlWidget | Displays local or remote HTML content using the Chromium rendering engine. |
| roNetworkConfiguration | Used to configure Ethernet, WiFi, and local network parameters. |
| roDeviceInfo | Used to retrieve a wide array of system information, including model type, device serial number, and firmware version. |

p = CreateObject("roMessagePort")
video = CreateObject("roVideoPlayer")
gpio = CreateObject("roControlPort", "BrightSign")
gpio.SetPort(p)
video.SetPort(p) |
...
The above syntax makes use of a shortcut provided by the language: The interface name is optional, unless it is needed to resolve name conflicts. For example, the following two lines of code carry out the exact same function:
| Code Block |

gpio.SetPort(p) gpio.ifMessagePort.SetPort(p) |

BrightScript Objects consist only of interfaces, and interfaces define only methods. There is no concept of a "property" or variable at the object or interface level. These must be implemented as "set" or "get" methods in an interface.
