Hi Dark!

First you have to select the formfield with

function FindFormFieldByTitle (for example)

and with the returning (longint) id you can use

color := QP.GetFormFieldBachgroundColorType(index);

color (as an integer variable) should contain value 1 for gray.

Hi Dark!

Here you can find code samples how to start with QuickPDF:
http://www.debenu.com/products/development/debenu-pdf-library/help/samples/
There's also the Quick PDF Library Demo distributed with the Quick PDF Library installer package.
With the demo.exe it's very easy to try functions and see the results.
And the best at the end: The Quick PDF Library 8 Developer Guide:
http://www.quickpdflibrary.com/docs/Quick%20PDF%20Library%208%20Developer%20Guide.pdf
At "Tasks" -> "PDF Forms" ... you'll find many samples regarding forms.
This really should help you on your first steps.

Cheers, Ingo
