关键是使用GetConsoleWindow和DwmEnableBlurBehindWindow功能.

GetConsoleWindow函数检索与调用进程关联的控制台使用的窗口句柄.

DwmEnableBlurBehindWindow函数启用提供的窗口句柄上的模糊效果(玻璃).

program ConsoleGlassDelphi;

{$APPTYPE CONSOLE}

    uses
  Windows,SysUtils;

type
  DWM_BLURBEHIND = record
    dwFlags                 : DWORD;
    fEnable                 : BOOL;
    hRgnBlur                : HRGN;
    fTransitionOnMaximized  : BOOL;
  end;

function DwmEnableBlurBehindWindow(hWnd : HWND; const pBlurBehind : DWM_BLURBEHIND) : HRESULT; stdcall; external  'dwmapi.dll' name 'DwmEnableBlurBehindWindow';//function to enable the glass effect
function GetConsoleWindow: HWND; stdcall; external kernel32 name 'GetConsoleWindow'; //get the handle of the console window

function DWM_EnableBlurBehind(hwnd : HWND; AEnable: Boolean; hRgnBlur : HRGN = 0; ATransitionOnMaximized: Boolean = False; AFlags: Cardinal = 1): HRESULT;
var
  pBlurBehind : DWM_BLURBEHIND;
begin
  pBlurBehind.dwFlags:=AFlags;
  pBlurBehind.fEnable:=AEnable;
  pBlurBehind.hRgnBlur:=hRgnBlur;
  pBlurBehind.fTransitionOnMaximized:=ATransitionOnMaximized;
  Result:=DwmEnableBlurBehindWindow(hwnd,pBlurBehind);
end;

begin
  try
    DWM_EnableBlurBehind(GetConsoleWindow(),True);
    Writeln('See my glass effect');
    Writeln('Go Delphi Go');
    Readln;
  except
    on E:Exception do
      Writeln(E.Classname,': ',E.Message);
  end;
end.

这只是一个基本的例子;您必须检查Windows操作系统版本以避免问题.
