Title: Add a drop shadow to your app under XP
Heres a nice way of adding a drop shadow to your application under Windows XP.
unit Unit1;
interface
uses
Windows, Messages, SysUtils, Classes, Graphics, Controls, Forms, Dialogs;
type
TForm1 = class(TForm)
private
{ Private declarations }
public
{ Public declarations }
protected
procedure CreateParams(var Params: TCreateParams); override; // Important !
end;
var
Form1: TForm1;
implementation
{$R *.DFM}
{------------------------------------------------------------}
// Here we check of the user is running Windows XP
function IsWinXP: Boolean;
begin
Result := (Win32Platform = VER_PLATFORM_WIN32_NT) and
(Win32MajorVersion = 5) and (Win32MinorVersion = 1);
end;
{------------------------------------------------------------}
{------------------------------------------------------------}
// Check if it is Windows XP if all is OK then create the drop shadow
procedure TForm1.CreateParams(var Params: TCreateParams);
const
CS_DROPSHADOW = $00020000;
begin
inherited;
if IsWinXP then
Params.WindowClass.Style := Params.WindowClass.Style or CS_DROPSHADOW
else
end;
{------------------------------------------------------------}
end.
This code also checks if it is running under Windows XP, if it is you get the drop shadow if not it does nothing.
