Good morning people, i am using fpcef web browser engine, and i need
to make the browser download files when the user click on it, but
nothing happens.

What i need to configure or program to get that working?

I found this on cef3intf but i don't know how to use it?

  ICefBeforeDownloadCallback = interface(ICefBase)
['{5A81AF75-CBA2-444D-AD8E-522160F36433}']
    procedure Cont(const downloadPath: ustring; showDialog: Boolean);
  end;

Yes its working!!!



It is very simple, do one click on the Tchromium object of your
browser, then click on "Events"  select the option OnBeforeDownload
twice, so in the code for this event just do something like this:

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.browserBeforeDownload(Sender: TObject;  const
Browser: ICefBrowser; const downloadItem: ICefDownloadItem;  const
suggestedName: ustring; const callback:
ICefBeforeDownloadCallback);begin       
callback.Cont(Concat(GetUserDir(),suggestedName),true);end;   
This is the way to use the IcefBeforeDownloadCallback constants...!
The suggetedName contains the file name and extension automatically on
the event.

I think i can help more people.

This is good for windows, but it does not work on Linux, any ideas?

I just tested and I get this error:

Code: [Select]WARNING:file_dialog_manager.cc(332)] No file dialog
runner available for this platform
This means one needs to implement a file dialog handler. A reference
implementation can be found at https://bitbucket.org/chromiumembedded/
cef/src/9928036f638f3a2e1bcccf18c28d940e473f82cb/tests/cefclient/brows
er/dialog_handler_gtk.cc

In fpCEF this means implementing the OnFileDialog callback.

Good news thanks to the developer it is running for Linux too, take a
look at the last version of FPCEF on GIT!

But you need to do something more, a example is available on
Examples/LCLCefClient (and yes you need the developer last fixes or to
rebuild lazarus with new FPCEF version)
