Ejemplos de uso :

Código: delphi


procedure TForm1.Form_EffectsClick(Sender: TObject);

var
  effects_manager: T_DH_Form_Effects;

begin

  effects_manager := T_DH_Form_Effects.Create();

  effects_manager.window_transparent(Form1, 240);
  effects_manager.window_effect(Form1.Handle,'center',100);
  effects_manager.Effect_Marquee_Label_DownUp(Panel1, Label1, 1);
  effects_manager.Effect_Marquee_Label_LeftRight(Label2, 'left', 1);
  Effect_Marquee_Form_Caption_LeftRight(Form1, 'right', 1);
  Effect_Load_Another_Form(Form1, About, 'effect2', 1, 5, 300);
  Effect_Load_Another_Form(Form1, About, 'effect1', 1,10,200);

  effects_manager.Free;
