I would like some examples of how to display content using zones in a custom BrightScipt file. Specifically, how does one display TextWidgets from scratch? As a general rule, is it better to use roTextField() or roTextWidget() for system messages and UI feedback? For example: if I have a script that is processing content or saving settings and I'd like to display legible, nice looking information to a user, what are the reasons to use one over the other? Thanks

  Give me a specific example of what you want to see? There are sample scripts in the object reference guide. You want to use a rotextwidget for your text zones.
  
  There's a show and hide function you can use with text widgets, and a push command to add strings to your text widget.

  Hi Lyndon,
  I slightly altered a code example from the BrightSign Object Reference for BrightSign software version 3.3.78 on pages 67 and 68 (under roBrightPackage()) but I was not able to get this to work. I put this snippet exactly as-is into a file named showtxt.brs and ran it manually from the BrightSign Shell as:
  
  BrightSign> script usb1:/showtxt.brs
REM Print Me

Sub Main()
    r = CreateObject("roRectangle", 20, 668, 1240, 80)
    textWidget = CreateObject("roTextWidget",r,1,2,1)
    r = CreateObject("roRectangle", 20, 20, 1200, 40)
    textWidget.SetSafeTextRegion(r)
    textWidget.SetForegroundColor(&hff303030)
    textWidget.SetBackgroundColor(&hffffffff)
    textWidget.PushString("Hello World!")
    textWidget.Show()
End Sub
  The script appeared to run without errors but I did not see any text on the video output.

  It might be because the script exited to the shell at the end of running. Inside the main function, at the very end, add a sleep statement to keep the script active. Sleep is in terms of milliseconds. So, to keep it running for 30 seconds, add:
  
  sleep(30000)

  That did the trick. Thanks Lyndon!
  
  Working code:
  REM Print Me

Sub Main()
   r = CreateObject("roRectangle", 20, 668, 1240, 80)
   textWidget = CreateObject("roTextWidget",r,1,2,1)
   r = CreateObject("roRectangle", 20, 20, 1200, 40)
   textWidget.SetSafeTextRegion(r)
   textWidget.SetForegroundColor(&hff303030)
   textWidget.SetBackgroundColor(&hffffffff)
   textWidget.PushString("Hello World!")
   textWidget.Show()
   ' Give the BrightSign time to process the command before exiting
   sleep(30000)
End Sub

  The sleep is only required because you don't have a loop of any kind of the script.
