Delphi添加图层蒙版，运行本程序后，在屏幕上添加一层阴影，透明度大概在70%左右，可看作是在屏幕上方蒙了一层薄膜的感觉，代码简单：procedure TForm1.FormCreate(Sender: TObject);
var
bTrans: Byte;
OldStyle: Integer;
begin
form1.Color := clGradientActiveCaption;
WindowState := wsMaximized;
BorderStyle := bsNone;
FormStyle := fsStayOnTop;
OldStyle := GetWindowLong(Handle, GWL_EXSTYLE);
SetWindowLong(Handle, GWL_EXSTYLE, OldStyle or WS_EX_LAYERED Or WS_EX_TRANSPARENT);
bTrans := 128;
SetLayeredWindowAttributes(Handle, 0, bTrans, LWA_ALPHA);
end;
