Delphi LiveBindings如何绑定一个对象(转)

原文 http://www.malcolmgroves.com/blog/?p=1084

一、新建VCL工程加入TAdapterBingSource控件

二、定一个TPerson类 

MyPerson : TPerson;

 TPerson = class
  private
    FAge: Integer;
    FLastname: string;
    FFirstname: string;
  public
    constructor Create(const Firstname, Lastname : string; Age : Integer); virtual;
    property Firstname : string read FFirstname write FFirstname;
    property Lastname : string read FLastname write FLastname;
    property Age : Integer read FAge write FAge;
  end;

三、双击并加入事件代码

1.创建一个对象实列Person

2.创建一个BindSourceAdapter

• self,   指定TObjectBindSource的归属
• MyPerson,需要邦定对象实例
• True,是否自动释放,如果否则False 默认值为True

procedure TForm4.AdapterBindSource1CreateAdapter(Sender: TObject;
  var ABindSourceAdapter: TBindSourceAdapter);
begin
    MyPerson :=TPerson.Create('test','test1', 13);
    ABindSourceAdapter := TObjectBindSourceAdapter<TPerson>.Create(Self, MyPerson, True);
end;

 

 

四、放一个TStringGrid对象 在Events LiveBindings点击BindVisually
