CEF4Delphi 常用设置

Posted 2020-10-18 全能中间件

CEF4Delphi 是由 SalvadorDíazFau 创建的一个开源项目，用于在基于Delphi的应用程序中嵌入基于Chromium的浏览器。

CEF4Delphi 基于Henri Gourvest 公司的 DCEF3。DCEF3的原始许可证仍适用于CEF4Delphi。阅读任何* .pas文件的第一行中的许可条款。

CEF4Delphi 使用CEF 3.3239.1709.g093cae4，其中包括铬63.0.3239.109。CEF4Delphi使用的CEF3二进制文件可以在spotify下载：

64bit - > http://opensource.spotify.com/cefbuilds/cef_binary_3.3239.1709.g093cae4_windows64.tar.bz2

CEF4Delphi是在Delphi 10.2 Tokyo上开发和测试的，已经在Delphi 7，Delphi XE和Delphi 10中测试过了。

 下面的代码，演示如何将 cef 文件放到一个单独的目录下面，以及让 cef 使用内置的 flash：

function CefLibPath: string;
begin
{$IFDEF CPUX64}
  Result := ‘CEF_3.3239.1709\Core64‘;
{$ELSE}
  Result := ‘CEF_3.3239.1709\Core‘;
{$ENDIF}
end;

function PpapiFlashFileName: string;
begin
{$IFDEF CPUX64}
  Result := CefLibPath + ‘\plugins\pepflashplayer64.dll‘
{$ELSE}
  Result := CefLibPath + ‘\plugins\pepflashplayer32.dll‘
{$ENDIF}
end;

begin
  GlobalCEFApp := TCefApplication.Create;

  // In case you want to use custom directories for the CEF3 binaries, cache, cookies and user data.
  // If you don‘t set a cache directory the browser will use in-memory cache.
  GlobalCEFApp.FrameworkDirPath := CefLibPath;
  GlobalCEFApp.ResourcesDirPath := CefLibPath;
  GlobalCEFApp.LocalesDirPath   := CefLibPath + ‘\locales‘;
  GlobalCEFApp.Cache            := CefLibPath + ‘\cache‘;
  GlobalCEFApp.Cookies          := CefLibPath + ‘\cookies‘;
  GlobalCEFApp.UserDataPath     := CefLibPath + ‘\User Data‘;
  // GlobalCEFApp.CustomFlashPath  := CefLibPath + ‘\plugins‘;
  GlobalCEFApp.LocalesRequired := ‘zh-CN‘;
  GlobalCEFApp.FlashEnabled    := False;
  GlobalCEFApp.EnableGPU       := True; // Enable hardware acceleration
  GlobalCEFApp.DisableGPUCache := True; // Disable the creation of a ‘GPUCache‘ directory in the hard drive.
  GlobalCEFApp.AddCustomCommandLine(‘--ppapi-flash-path‘, PpapiFlashFileName);

  // You *MUST* call GlobalCEFApp.StartMainProcess in a if..then clause
  // with the Application initialization inside the begin..end.
  // Read this https://www.briskbard.com/index.php?lang=en&pageid=cef

  if GlobalCEFApp.StartMainProcess then
  begin
    Application.Initialize;
{$IFDEF DELPHI11_UP}
    Application.MainFormOnTaskbar := True;
{$ENDIF}
    Application.CreateForm(TForm1, Form1);
    Application.Run;
  end;

  GlobalCEFApp.Free;

end.
