Firemonkey 的多重效果

Question

使用 Firemonkey（柏林更新 2）是否可以在 TButton 上同时使用 TShadowEffect 和 TGlowEffect ？

要获得阴影效果，我需要禁用发光效果。

Answer 1

制作复合组件：将 TButton 放入 TRectangle（形状）；将 TShadowEffect 附加到 TButton 并将 TGlowEffect 附加到外部 TRectangle 容器。

unit FMX_TwoEffects;

interface

uses
  System.SysUtils, System.Types, System.UITypes, System.Classes, System.Variants,
  FMX.Types, FMX.Controls, FMX.Forms, FMX.Graphics, FMX.Dialogs, FMX.Effects,
  FMX.Controls.Presentation, FMX.StdCtrls, FMX.Objects;

type
  TForm2 = class(TForm)
    Button1: TButton;
    Rectangle1: TRectangle;
    ShadowEffect1: TShadowEffect;
    GlowEffect1: TGlowEffect;
  private
    { Private declarations }
  public
    { Public declarations }
  end;

var
  Form2: TForm2;

implementation

{$R *.fmx}

end.
