Hello!

I made simple Web Browser with fpCEF and I need to print document with
function:
Chromium1.Browser.Host.PrintToPdf
I need to do silent print to PDF to specified location ( ParamStr(0) )
with filename := document title.
Similiar funciton works in cefclient example which I found at
cefbuilds.com (this example ask where to save a file - I dont even
need that), but it is wroten in C language and I cant copy that.
My knowledge ends at this moment. I know that I have to build a
callback function, but I dont have idea how to make it properly.
Could anyone help me with that?

You can do it so:Code: Pascal  [Select][+][-]window.onload =
function(){var x1 = document.getElementById("main_content_section");
if (x1) { var x = document.getElementsByClassName("geshi");for (var i
= 0; i procedure TForm1.Button1Click(Sender: TObject);var 
CefPdfPrintSettings: TCefPdfPrintSettings;  EmptyCefStringUtf16:
TCefStringUtf16;begin  FillByte(EmptyCefStringUtf16,
SizeOf(EmptyCefStringUtf16), 0);  
CefPdfPrintSettings.backgrounds_enabled := 1; 
CefPdfPrintSettings.header_footer_enabled := 0; 
CefPdfPrintSettings.header_footer_title := EmptyCefStringUtf16; 
CefPdfPrintSettings.header_footer_url := EmptyCefStringUtf16; 
CefPdfPrintSettings.landscape := 0;  CefPdfPrintSettings.margin_bottom
:= 0;  CefPdfPrintSettings.margin_left := 0; 
CefPdfPrintSettings.margin_right := 0;  CefPdfPrintSettings.margin_top
:= 0;  CefPdfPrintSettings.margin_type := PDF_PRINT_MARGIN_DEFAULT; 
CefPdfPrintSettings.page_height := 0;  CefPdfPrintSettings.page_width
:= 0;  CefPdfPrintSettings.selection_only := 0;  
Chromium.Browser.Host.PrintToPdf('C:\01\test.pdf',
CefPdfPrintSettings, Nil);end; The description of the Settings are in
the definition.

[Edit] I also added some infos here http://wiki.freepascal.org/fpCEF3

language).
