I have installed this component and now there are too many errors and no documentation.
For example, I have varables

Code: Select all

map: ICefStringMultimap
Request: ICefRequest;
Header: ICefStringMultimap;

, in cef3 I wrote

Code: Select all

  map := ICefStringMultimapOwn.Create;
  Request := TCefRequestRef.New;
  Header := TCefStringMultimapOwn.Create;

What is now?

Also

Code: Select all

CefSingleProcess
CefUserAgent
CefLocale
CefUserDataPath
CefCache
CefAcceptLanguageList:='ru';
TCefCookieManagerRef.Global(CefBack);
.SetStoragePath(CookiesPath, True, CefBack);

Now you can use the TChromium.CustomHeaderName and TChromium.CustomHeaderValue properties to set HTTP headers easily.

Here you have an example in case you still want to do it manually :

Many of those variables are now properties of GlobalCEFApp.

Use GlobalCEFApp.SingleProcess, GlobalCEFApp.UserAgent, GlobalCEFApp.Locale, GlobalCEFApp.UserDataPath, GlobalCEFApp.Cache, GlobalCEFApp.AcceptLanguageList, GlobalCEFApp.Cookies, etc.

Read this page :
https://www.briskbard.com/index.php?lang=en&pageid=cef

Most of that information is still relevant to the OldCEF4Delphi component. Also, open the SimpleBrowser and SimpleBrowser2 demos and read the code comments.

I would suggest that you take a look at the demos and pick one that is similar to what you need. Then use it as a template for your application.
If your application uses the OSR mode then perhaps you should use the SimpleOSRBrowser demo.

Be careful with the GlobalCEFApp.SingleProcess property. That mode is NOT supported by CEF and it's a known cause of issues. You should only use it for debugging purposes.

One more thing.

OldCEF4Delphi and CEF4Delphi use the recomended settings to initialize CEF.

That means that by default you use the "multithread message loop" (known as CEF_MULTI_THREADED_MESSAGE_LOOP in dcef3) and most of the TChromium and GlobalCEFApp events are executed in a CEF thread.

As you know, VCL is not thread safe and you should not create, destroy or modify VCL controls inside those events. The demos are oversimplified and they still modify controls inside those events but you should move that code to the main application thread.

Great! It works. Thanks.
I have compiled my project with no errors, but... it crashes after creating... Damn.

I did it! Now it works with CEF4Delphi.
But I still can not send request.

Code: Select all

  Request.Url:='https://google.com';
  request.Method:='GET';
  request.SetReferrer('https://yahoo.com',REFERRER_POLICY_DEFAULT);
  chromium2.Browser.MainFrame.LoadRequest(Request);

cases an error

Access violation at address 006AF59D in module 'browser.exe'. Read of address 00000000.

I think because request is not created.
In earlier version I used

Code: Select all

Request := TCefRequestRef.New;

New version does not contain TCefRequestRef
