Hi,

I use qwebview to display pages Html in my application. This works fine, in Windows, Linux, Mac OSx (i386 and powerpc). But, when I want print the content of my qwebview, I have just a blank page, on Windows only.

This is the code I use:
qwebview_print(webview1.handle,webview1.hprinter);

where hprinter is :

hprinter := QPrinter_create();

Why the page is blank on printer?
Have any idea?

Thanks for your help.

What says QPrinter_isValid(), QPrinter_printerName(),
QPrinter_printProgram().. QPrinter_outputFormat() ?
eg:
hprinter .= QPrinter_create();
  QPrinter_isValid(hprinter);
  QPrinter_printerName(hprinter);
  QPrinter_outputFormat(hprinter);
  QPrinter_printProgram(hprinter);
  QPrinter_pageSize(hprinter);

Thanks for your time.

QPrinter_isValid returns : "true";
Qprinter_Printername returns the name of the printer I select with printdialog1.execute (Canon MP600R Printer)
I set PrinterOutputFormat with "QPrinterNativeformat" I set Printer PageSize to "0" (QPrinterA4)

Qprinter_PrintProgram returns : '' (empty string)

is this last thing my problem?

P.S. Sorry for my english....

I tested on windows and linux and it just works.

test code (lacks some *_destroys, just for testing purposes)

try
  PrnInfo:=QPrinterInfo_Create;
  QPrinterInfo_DefaultPrinter(PrnInfo);
  if QPrinterInfo_isNull(PrnInfo) then
    begin
    writeln('no printer found');
    exit;
    end;
  Prn:=QPrinter_Create(PrnInfo);
  QPrinterInfo_printerName(PrnInfo, at w);
  writeln('Default Printer Name:',w);
  PrintDlg:=QPrintDialog_create(Prn);
  QPrintDialog_exec(PrintDlg);
  QPrinter_printerName(QAbstractPrintDialog_printer(PrintDlg), at w);
  writeln('Chosen Printer Name:',w);
  QWebView_print(ActiveTab.WebView,QAbstractPrintDialog_printer(PrintDlg));
except on E:Exception do
  writeln('Exception occurred in FilePrint:',E.Message);
end;

Hi
Thx,

Hi Den Jean,

I try with your code, but it dont work.
Can you add this print function in the project lclwebkit, try it on windows, and then put the new project on the net?

It's a good manier to ensure where is the problem for me.

(my english is very bad, I know. I hope you understand my message)

Hi,

Indeed, it works in lclwebkit, so I will make changes in my program. But But I do not have much time right now, is a lot of changes in my project.

But, I'll tell you when I could modify and test my project.

Thanks for your help.
