delphi - How to cancel a FastReport print job?

Question

How do I show a MessageBox when a print job is canceled in FastReport's Print Job Dialog?

Answer 1

当 frxReportPrint.Print 返回 false 时，要么是用户取消，要么是打印出错。所以你需要检查 Errors.Text 是否为空，例如：

if not frxReportPrint.Print then
  if frxReportPrint.Errors.Text = '' then
    UserCancel := true
  else
    Abort; // something wrong during printing.

Answer 2

if frxReport1.Print then Showmessage('Aborted');
