Unfortunately I myself badly distracted attention using the keyword "screenshot", sorry for that: I rather tought of a "somehow textual" export, from which interesting snippets (lets say a grid of serial numbers) could be copied from.
Suppose you have some form in LibreOffice Base, bound to any data source. You can export forms, including your currently displayed data, into a PDF, from which values can be copied as text.
Is something similar possible with a lazarus form (or a component like a dbgrid)?
