Remarks

If the WebUI browser environment provides multiscreen information, methods that take a (screen) parameter report information for the specified screen. Multiscreen information is currently available only in a secure context (https or localhost) in Chromium-based browsers. Screen numbers are not necessarily in the same order as in the Java Swing GUI client.

Example

rem 'Obtain the instance of the BBjSystemMetrics object

rem 'Obtain the instance of the BBjAPI object
let myAPI! = BBjAPI()

rem 'Open the SysGui device
SYSGUI = UNT
OPEN (SYSGUI)"X0"

rem 'Obtain the instance of the BBjSysGui object
let mySysGui! = myAPI!.getSysGui()

rem 'Obtain the instance of the BBjSystemMetrics Object
let mySystemMetrics! = mySysGui!.getSystemMetrics()
