[cnpack\cnvcl\Examples\AutoOption的TStringlist]Help
cnpack\cnvcl\Examples\AutoOption的Demo。
在MyClass1里加了属性
private
Fsl : TStringList;
procedure Setsl(Asl: TStringList);
published
constructor Create();
property sl: TStringList read Fsl write Setsl;
constructor TMyClass1.Create;
begin
Fsl := TStringList.Create;
Fsl.Add('a');
Fsl.Add('b');
end;
procedure TMyClass1.Setsl(Asl: TStringList);
begin
ShowMessage('Setting');
end;
我是SBT.T为啥Apply以后Setls不起作用而是直接更改sl呢0.0
是不是小生犯了原则 Sex 问题0.0

P.M.
估计代码里头是直接处理的sl.Add或sl.Text :=,用这方式赋值的。
这样赋值是不会调用SetSl的,而只会直接使用Fsl这对象来进行操作。

测试代码,点击btnSet时,不会触发Set事件:
unit Unit1;
interface
uses
Windows, Messages, SysUtils, Classes, Graphics, Controls, Forms, Dialogs,
StdCtrls;
type
TForm1 = class(TForm)
btnSet: TButton;
btnShow: TButton;
procedure FormCreate(Sender: TObject);
procedure FormDestroy(Sender: TObject);
procedure btnSetClick(Sender: TObject);
procedure btnShowClick(Sender: TObject);
private
FList: TStringList;
procedure SetList(const Value: TStringList);
{ Private declarations }
public
{ Public declarations }
property List: TStringList read FList write SetList;
end;
var
Form1: TForm1;
implementation
{$R *.DFM}
procedure TForm1.FormCreate(Sender: TObject);
begin
FList := TStringList.Create;
List.Add('aaa');
end;
procedure TForm1.SetList(const Value: TStringList);
begin
ShowMessage('Set 了');
end;
procedure TForm1.FormDestroy(Sender: TObject);
begin
FList.Free;
end;
procedure TForm1.btnSetClick(Sender: TObject);
begin
List.Text := 'xxxxxxx';
List.Add('bbbbbb');
end;
procedure TForm1.btnShowClick(Sender: TObject);
begin
ShowMessage(List.Text);
end;
end.
