FMXChangeStyle

fmxchangestyle

FMX样式通过使用默认效果而变化（过渡效果，例如TBlurTransitionEffect，tfadetransitionEffect，...）

 uses
  FMX.StyleChanger, FMX.Filter.Effects;

type
  EffectClass = TBlurTransitionEffect;

TStyleExt.Change<EffectClass>(Self, StyleBookDark,
   function(Effect: EffectClass): TBitmap
   begin
     Result := Effect.Target;
     Effect.Progress := 0 ;
   end );
