Is it possible to use CEF4Delphi in a Linux Console Application? Without using any forms?

Hi,

I've never tried that but I guess it should be possible.

You can port the Lazarus_Windows/ConsoleBrowser2 demo to Linux.
You will probably have to replace some of its code with the code from the Lazarus_Linux_GTK3/OSRExternalPumpBrowser demo.

Thank you. I can't believe how couldn't I see ConsoleBrowser2 demo.

I am trying to port it now. If I am successful, I will share here.

I'm also creating a new console demo that should work on Linux.
Your message made me realize that it was missing.

I just uploaded the Lazarus_Linux_Console/ConsoleBrowser demo to GitHub.

It just takes a snapshot of the default URL and saves it as snapshot.png.

It uses a browser in OSR mode with a second executable for the CEF subprocesses.

Thank you. You are great.

I also tried and it didn't work

I am trying to use CefRegisterExtension function on the demo, but OnWebKitInitialized is not running. Can you help about this?

That event is called on the render subprocess and Lazarus debugs the main browser process.

Read this document if you need to debug the code in that event :

Edit :
The demos that use a different executable for the CEF subprocesses have to implement the events that run in CEF subprocesses in the subprocess project. For example, the Lazarus_Windows/JavaScript/JSWindowBindingSubProcess demo implements OnContextCreated in SubProcess.lpr

Hmm..

It seems like it's executing while I set GlobalCEFApp.SingleProcess := True;

but it's not executing when it's false.

Why is that?
