This example uses a button, a Page Control, and a Print dialog box on a form. When the user clicks the button, the print dialog is displayed. The user can select any subset of the pages in the page control for printing. The selected pages are then printed.
To run this example successfully, you must add the Printers unit to the uses clause of your unit.
procedure TForm1.Button1Click(Sender:TObject);
var
I, Start, Stop: Integer;
begin
PrintDialog1.Options := [poPageNums, poSelection];
PrintDialog1.FromPage := 1;
PrintDialog1.MinPage := 1;
PrintDialog1.ToPage := PageControl1.PageCount;
PrintDialog1.MaxPage := PageControl1.PageCount;
if PrintDialog1.Execute then
begin
{ determine the range the user wants to print }
with PrintDialog1 do
begin
if PrintRange = prAllPages then
begin
Start := MinPage - 1;
Stop := MaxPage - 1;
end
else if PrintRange = prSelection then
begin
Start := PageControl1.ActivePage.PageIndex;
Stop := Start;
end
else { PrintRange = prPageNums }
begin
Start := FromPage - 1;
Stop := ToPage - 1;
end;
end;
{ now, print the pages }
with Printer do
begin
BeginDoc;
for I := Start to Stop do
begin
PageControl1.Pages.PaintTo(Handle, 10, 10);
if I <> Stop then
NewPage;
end;
EndDoc;
end;
end;
end;
