Title: Display a memo at preview but not print it
Post by: derles on August 05, 2016, 10:47:16 pm

Hello,
In a report I have a memo that I need to be displayed in the preview, but not printed on paper.

Why do I need this? Because this report will be printed on colored paper (blue, yellow, green or pink), and I need to display a large colored rectangle (FillColor property) for reference only in the preview, so that the operator can check the correct paper in the printer.

A BeforePrint event could be helpfull. Sadly it doesn't exists.

Can anybody help me with this?

Thankssss.

Daniel

Changing de Page background color could be usefull too, instead using a colored memo.
But my problem remains: display at preview, but no print on paper.

In Delphi I used to substitute the printer.canvas with a normal TCanvas and render the output to that canvas. I guess that should be possible in Lazarus too.
