    The BPL files should be created in $(BDSCOMMONDIR)\Bpl and not in the WebView4Delphi\packages directory.

     

    Perhaps the "Package output directory" option is not set to $(BDSCOMMONDIR)\Bpl

     

    Open the Tools -> Options... menu option and then select the "Environment options -> Delphi options -> Library" node in the left tree view.

    There you can check the "Package output directory" value.

     

    If you can't modify that setting try adding the WebView4Delphi\packages directory to the search path.

    Build WebView4DelphiVCLRTL.bpl, WebView4DelphiFMXRTL.bpl, WebView4DelphiVCL_designtime.bpl and WebView4DelphiFMX_designtime.bpl individually (in that order) or download the latest WebView4Delphi version from GitHub.

     

    I recently fixed a project order issue in the project group file thanks to the information on this thread.

     

    This Wiki article has all the details to install WebView4Delphi in Delphi.

    I just made public the WebUI4Delphi open source project at GitHub.

    WebUI4Delphi is a WebUI wrapper, which allows you to use any web browser as a GUI, with Delphi in the backend and HTML5 in the frontend.

    WebUI doesn't embed a web browser. It just connects your Delphi application with the installed web browser using a fast protocol so you can use HTML5 as part of the GUI.

    WebUI4Delphi can be used in 64 bit Delphi applications for Windows. Linux and MacOS support needs testing.

    There are several VCL, FireMonkey and console demos.

    Hi

    Has anyone tried out this CEF4Delphi

     

    https://github.com/salvadordf/CEF4Delphi

     

    It seems it can embed chromium based browser into Delphi App and support for Linux

     

    Please advise

     

    regards

    chris

     

    Yes. CEF4Delphi works on Windows, Linux and macOS.

     

    There are some unresolved issues in Linux but it works :

    Some suggestions :

    • Use a custom captcha when registering new users. Some forum plugins allow you to create custom questions or things like that. Don't use any version of Google recaptcha. All of them were cracked ages ago.
    • Some forums allow you to moderate the first messages of new users. This gives you some extra work but it blocks all spammers that registered manually.
    • Some forums have plugins that block new users that try to use known spammers IPs, email addresses, etc.

    Besides the JavaScript, HTML or CSS solutions you can also use the Emulation.setScrollbarsHidden method in the DevTools protocol:

    https://chromedevtools.github.io/devtools-protocol/tot/Emulation/#method-setScrollbarsHidden

     

    If you use CEF4Delphi use this code : 

    procedure TForm1.HideScrollbars;
var
  TempParams : ICefDictionaryValue;
begin
  try
    TempParams  := TCefDictionaryValueRef.New;
    TempParams.SetBool('hidden', True);
    Chromium1.ExecuteDevToolsMethod(0, 'Emulation.setScrollbarsHidden', TempParams);
  finally
    TempParams := nil;
  end;
end;

    If you use WebView4Delphi use this code : 

    procedure TForm1.HideScrollbars;
begin
  WVBrowser1.CallDevToolsProtocolMethod('Emulation.setScrollbarsHidden', '{"hidden":true}');
end;

    Run the MiniBrowser demo and navigate to that web page. Then click on the top-right button and open the DevTools window.

    Switch to the Console tab, type your JavaScript code and press enter to read the error message : 

    document.getElementById("linkRefresh").click();

    The problem could be something as simple as a syntax error or that page could have multiple documents because it could have several frames. In any case, debugging the JavaScript code in the console tab is the best solution before calling WVBrowser.ExecuteScript

    So, may I  ask you if there is any (perhaps older) version of WebView4Delphi, compatible with Delphi 6 ?

    I'm sorry but WebView4Delphi requires at least Delphi 7.

    If you need to test this component you can also use Lazarus or Delphi Community Edition.

    It's not easy to use Chromium command line switches with TEdgeBrowser.

     

    Consider using WebView4Delphi instead and set GlobalWebView2Loader.AllowFileAccessFromFiles to true.

     

    You can also use the VirtualHostBrowser demo as a template for your application. It maps a local directory to a custom domain to load files from the hard drive.

    The WebView2 API doesn't have any interface to use custom proxy settings but you can use the Chromium command line switches.

    If you use TEdgeBrowser then you will have to create an ICoreWebView2EnvironmentOptions instance with those switches and pass it as a parameter in CreateCoreWebView2EnvironmentWithOptions.

     

    However, if you decide to use WebView4Delphi then all this is already implemented and you only have to set the GlobalWebView2Loader.ProxySettings properties.

     

    At this time, any WebView2 wrapper will only allow you to set the proxy settings once. If your application needs to change the proxy settings multiple times at run-time then you need to use CEF4Delphi.

    Great.  Thank you.

     

    Have you tested going to drive.google.com by any chance?  Google is no longer allowing the custom browser that I last compiled with CEF4.  I have been meaning to recompile to get around the problem.  Google lets me into gmail and they let me download items from drive when the notices come into gmail, but direct use of google drive is blocked.  They detect my CEF4 browser as an old version of "Firefox" now. 

     

     

    I haven't checked that.
    Sometimes this is just the result of some temporal issue in the Google servers and they fix it but sometimes this a deliberate safety measure from Google against all embedded browsers.
    Try using a modern Firefox user agent string.

    I just published a new project in GitHub called WebView4Delphi.
    WebView4Delphi allows you to embed Chromium based web browsers in your Delphi or Lazarus applications using the WebView2 runtime.
    It uses the latest stable version of the WebView2 nuget package 1.0.1054.31.
    I used many of the tricks I learned creating CEF4Delphi and you will notice many similarities if you used it.
    I still have to write the documentation but you can build the available demos to see it working in VCL, FMX and Lazarus apps.
    There are a few things pending like the "windowless mode".
    It's being distributed with a simple MIT license so anyone can do whatever s/he wants with it.

    Check these points :

    • Assuming you use Windows 10, check if you can make that camera work with the "Camera" app.
    • Install Chrome or Chromium 84. Ideally you should try to install 84.0.4147.89 and make the camera tests with the latest CEF4Delphi version from GitHub. Test your camera with Chrome/Chromium on webcamtoy.com.
    • Open the SimpleBrowser2 demo and add GlobalCEFApp.EnableMediaStream := True; before the GlobalCEFApp.StartMainProcess call in the DPR file. Connect your camera, build the demo and test it in webcamtoy.com. 

    If your camera works on a similar Chrome version then it should work with the SimpleBrowser2 demo or any other CEF application.
