Hi there!

Excuse my poor English!

I'm beginning to use this great component by Kambiz R. Khojasteh. To begin with, many many thanks to him..

Ok..

It looks like I need to use limits on pages, i.e. in some cases my apps have so many pages to print and preview that it would be just inpractical to create them all in canvas ahead, not to mention memory requirements.

So It looks like that I must build up some buffer or just offer the user to preview one page at time, that is if they exceed 10 pages limit or so.

I'm looking at this object Preview and ThumbnailPreview and can't see methodes to just clear page/s and begin next segment...

Hmmm.. am I missing something?

All the best

Thanks..

1) I'm pretty sure my customers wan't like to see all pages of heavy lists in tumbnails and tabs, even if I can. We are talking about couple hundred pages in some lists!

2) Time is not the biggest issue.

3) Ok.. thats what I need.

Among other things I tryed..

Code: Select all

WITH PrintPreview DO
BEGIN
    BeginEdit(2);
    Pages[2].Clear;
    EndEdit;
END;

But.. nothing happends. Any ideas?

function BeginEdit(PageNo: Integer): Boolean;
Intializes Canvas to edit an existing page.

Code: Select all

with PrintPreview do
begin
  BeginEdit(2);
  try
    Canvas.Brush.Style := bsSolid;
    Canvas.Brush.Color := clWhite;
    Canvas.FillRect(PageBounds);
  finally
    EndEdit;
  end;
end;

LOL

Ok.. I will use this!
