求助：控件数组问题
在vb6中，可以设计控件数组（可视化的控件，如button），在编程实际中很有用，请问如何在delphi2005中实现呢？如：ommand1[i].text=“”（vb6）
你说的是不是delphi的数组属性啊？
type
TArrButton = array of TButton;
TTestProperty = class(TObject)
private
fButton: TArrButton;
function getaButton(i: Integer): TButton;
public
constructor Create(alength: Integer);
destructor destroy(); override;
property MyButton[index: Integer]: TButton read getaButton;
end;
TForm1 = class(TForm)
Button1: TButton;
Memo1: TMemo;
Edit1: TEdit;
procedure Button1Click(Sender: TObject);
procedure FormCreate(Sender: TObject);
procedure FormDestroy(Sender: TObject);
private
{ Private declarations }
fTestProperty: TTestProperty;
public
{ Public declarations }
end;
var
Form1: TForm1;
implementation
{$R *.dfm}
{ TTestProperty }
constructor TTestProperty.Create(alength: Integer);
var
I: Integer;
begin
SetLength(fButton, 10);
for i := Low(fButton) to High(fButton) do
begin
fButton[i] := TButton.Create(nil);
fButton[i].SetBounds(50*i, 50*i, 10*i, 10*i);
fButton[i].Parent := Form1;
fButton[i].Name := TButton.ClassName;
fButton[i].Caption := IntToStr(i) + ' 什么啊 ';
end;
end;
destructor TTestProperty.destroy;
var
I: Integer;
begin
for i := Low(fButton) to High(fButton) do
begin
FreeAndNil(fButton[i]);
end;
SetLength(fButton, 0);
inherited destroy();
end;
function TTestProperty.getaButton(i: Integer): TButton;
begin
if (i >= Low(fButton)) and (i <= High(fButton)) then
begin
Result := fButton[i];
end
else
begin
Result := nil;
end;
end;
procedure TForm1.Button1Click(Sender: TObject);
var
tempStr: string;
index: Integer;
begin
index := StrToIntDef(Edit1.Text, 0);
tempStr := fTestProperty.MyButton[index].Caption;
TButton(Sender).Caption := tempStr;
end;
procedure TForm1.FormCreate(Sender: TObject);
begin
fTestProperty := TTestProperty.Create(10);
end;
procedure TForm1.FormDestroy(Sender: TObject);
begin
fTestProperty.Free();
end;
end.
