设置RadioButton.Checked时阻止控制动画

Question

在显示该表单之前，我在第二个表单上设置了两个radiobuttons的Checked属性。每次单击按钮以设置Checked属性并显示表单我反转（“NOT”）Checked for each radiobutton。然后在显示表格时，可以清楚地看到发生的无线电按钮的动画（检查属性被更改）。它不会在第一次运行时发生，但会在表单的每个后续显示中发生。

我想阻止动画，只需让radiobuttons在显示表单时显示新设置的检查状态。有办法吗？

在设置Checked之前将无线电按钮放在禁用的面板上或使它们不可见不起作用。

Form1中：

type
  TForm1 = class(TForm)
    Button1: TButton;
    procedure Button1Click(Sender: TObject);
  private
  public
  end;

var
  Form1: TForm1;

implementation

{$R *.dfm}

uses Unit2;

procedure TForm1.Button1Click(Sender: TObject);
begin
  Form2.RadioButton1.Checked := not Form2.RadioButton1.Checked;
  Form2.RadioButton2.Checked := not Form2.RadioButton1.Checked;

  Form2.Show;
end;

Form1 DFM：

object Form1: TForm1
  Left = 0
  Top = 0
  Caption = 'Form1'
  ClientHeight = 81
  ClientWidth = 249
  Color = clBtnFace
  Font.Charset = DEFAULT_CHARSET
  Font.Color = clWindowText
  Font.Height = -11
  Font.Name = 'Tahoma'
  Font.Style = []
  OldCreateOrder = False
  PixelsPerInch = 96
  TextHeight = 13
  object Button1: TButton
    Left = 36
    Top = 24
    Width = 157
    Height = 25
    Caption = 'Set Radios and Show Form2'
    TabOrder = 0
    OnClick = Button1Click
  end
end

窗体2：

type
  TForm2 = class(TForm)
    Button1: TButton;
    RadioButton1: TRadioButton;
    RadioButton2: TRadioButton;
    procedure Button1Click(Sender: TObject);
  private
  public
  end;

var
  Form2: TForm2;

implementation

{$R *.dfm}

procedure TForm2.Button1Click(Sender: TObject);
begin
  Hide;
end;

end.

Form2 DFM：

object Form2: TForm2
  Left = 0
  Top = 0
  Caption = 'Form2'
  ClientHeight = 131
  ClientWidth = 176
  Color = clBtnFace
  Font.Charset = DEFAULT_CHARSET
  Font.Color = clWindowText
  Font.Height = -11
  Font.Name = 'Tahoma'
  Font.Style = []
  OldCreateOrder = False
  PixelsPerInch = 96
  TextHeight = 13
  object Button1: TButton
    Left = 44
    Top = 90
    Width = 75
    Height = 25
    Caption = 'Hide'
    TabOrder = 0
    OnClick = Button1Click
  end
  object RadioButton1: TRadioButton
    Left = 38
    Top = 20
    Width = 113
    Height = 17
    Caption = 'RadioButton1'
    TabOrder = 1
  end
  object RadioButton2: TRadioButton
    Left = 38
    Top = 44
    Width = 113
    Height = 17
    Caption = 'RadioButton2'
    TabOrder = 2
  end
end

Answer 1

Set the DoubleBuffered property of the TRadioButtons to True.
