delphi - Delphi Firemonkey中的鼠标事件动画

Question

我添加了一个按钮并向其添加了一个 BoxBlurEffect，并将以下属性设置为 BoxBlurEffect1。

//extracted form fmx file 

object BoxBlurEffect1: TBoxBlurEffect
  Trigger = 'IsMouseOver=true'
  Enabled = False
  BlurAmount = 0.009999999776482582
  object FloatAnimation1: TFloatAnimation
    AnimationType = atInOut
    Enabled = True
    Duration = 1.000000000000000000
    Loop = True
    Trigger = 'IsMouseOver=true'
    TriggerInverse = 'IsMouseOver=false'
    StartValue = 0.009999999776482582
    StopValue = 10.000000000000000000
    PropertyName = 'BlurAmount'
  end
end

我设置了loop = true，因为如果它是false，它就不会动画，它只是突然达到最终值。

所以我将其设置为true。但现在它正在循环(如名称所述)，而不仅仅是动画一次然后停止。

而且我还希望当我离开鼠标时它从停止值动画到开始值(仅一次)。当我的鼠标离开或进入时，新动画必须从当前值开始，而不是从最大值或最小值开始。

触发器并不总是像我期望的那样工作......

你可以这样做:

procedure TForm2.Button1MouseEnter(Sender: TObject);
begin
  BoxBlurEffect1.AnimateFloat('BlurAmount', 10, 1);
end;

procedure TForm2.Button1MouseLeave(Sender: TObject);
begin
  BoxBlurEffect1.AnimateFloat('BlurAmount', 0, 1);
end;

没有 TFloatAnimation:

  object Button1: TButton
    Position.Point = '(264,192)'
    Width = 80.000000000000000000
    Height = 22.000000000000000000
    OnMouseEnter = Button1MouseEnter
    OnMouseLeave = Button1MouseLeave
    TabOrder = 1
    StaysPressed = False
    IsPressed = False
    Text = 'Button1'
    object BoxBlurEffect1: TBoxBlurEffect
      BlurAmount = 0.009999999776482582
    end
  end
