BriskBard, CEF4Delphi, WebView4Delphi, WebUI4Delphi and WebUI4CSharp

There is no TNetEncoding class in Delphi XE and I cannot compile
MiniBrowser project from demos Cef 90.6.5. What to do in this case?

Sorry about that. I'll disable those calls for older Delphi versions as soon as I can.
Meanwhile, you can comment those lines to build the MiniBrowser demo with Delphi XE.

I just uploaded a small workaround for that issue.
Please, download CEF4Delphi from GitHub again.

Thank you, everything is fine

In this example, on the Chromium1BeforeDownload event, callback.cont saves the downloaded file to disk. How to open
a downloadable file using an external program

If you want to download that file using an external program you can do this :

• Cancel the download in Chromium1DownloadUpdated by calling callback.cancel
• Read the downloadItem.Url value and send it to the external program. You will have to read the documentation about that external program to know how can you start downloading a URL.

If you just want to download that file using CEF4Delphi and then open it with an external program then you can use "ShellExecute" as you can see here :

Thank you,

Chromium1BeforeDownload event, callback.cont function.
There is a way in cef4 to detect when an event is successful and the file is not busy

The MiniBrowser demo shows how to handle downloads. The TMiniBrowserFrm.Chromium1DownloadUpdated procedure checks the values of downloadItem.IsComplete, downloadItem.IsCanceled and downloadItem.IsInProgress to know the status of that item.

Thanks a lot
