Hello.
The event TChromium.OnLoadEnd is running in not main thread. Why in MiniBrowse example are not used any synchronization working with form components?

Code: Select all

procedure TMiniBrowserFrm.Chromium1LoadEnd(Sender: TObject;
  const browser: ICefBrowser; const frame: ICefFrame;
  httpStatusCode: Integer);
begin
  if (frame = nil) or not(frame.IsValid) then exit;

  if frame.IsMain then
    StatusBar1.Panels[1].Text := 'main frame loaded : ' + quotedstr(frame.name)
   else
    StatusBar1.Panels[1].Text := 'frame loaded : ' + quotedstr(frame.name);
end;

Hi,

You're right. All the VCL modifications in the demos should be done in the main application thread.
The only reason some of them do it inside CEF events is because I didn't want to complicate things even more.

It's highly recommended that all the VCL code should be executed in the main thread.

Understood, thank you.
