组件包本身不具有这个功能,需要自行修改代码以实现它。

我尝试着增加以下
procedure TCnOptionItem.setPasswordChar(const Value: string);
begin
FPasswordChar := Value;
end;
function TCnOptionItem.GetPasswordChar: string;
begin
if not VarIsNull(FPasswordChar) then
Result := FPasswordChar
else
Result := '#0';
end;
在TCnOptionItem = class(TCnBaseOption)的published中增加
property PassWordChar: string read GetPassWordChar write SetPassWordChar;
{* 关联对象属性密码掩码 }
不知道还要增加哪些代码,请指教!

代码已更新
请从 CVS 中更新 CnPack 最新的代码。
此次更新为 TCnAOTreeView 增加了一个 OnCreateInplaceEdit 事件,针对密码框的示例如下:
procedure TForm1.OnCreateInplaceEdit(Sender: TObject;
InplaceEdit: TControl; AOption: TCnBaseOption);
begin
if (InplaceEdit is TCustomEdit) and (AOption is TCnOptionItem) and
SameText(TCnOptionItem(AOption).PropName, 'Password') then
TEdit(InplaceEdit).PasswordChar := '*';
end;
详见 Demo 程序。

这句能不能改成这样的:
if (InplaceEdit is TCustomEdit) and (AOption is TCnOptionItem) and
(pos('password',TCnOptionItem(AOption).PropName)>0) then
TEdit(InplaceEdit).PasswordChar := '*';
这样就不会局限于密码的属性必须为Password,只要属性中包含password就是密码输入框,就以*显示文本内容。

我刚才作了以下测试:发现以下问题:
图一是正常显示时,密码确以明文显示出来;
图二为在输入密码时显示是正确的;

又增加了一个新事件
procedure TForm1.OnGetItemText(Sender: TObject; AOption: TCnOptionItem;
var AText: string);
begin
if SameText(TCnOptionItem(AOption).PropName, 'Password') then
AText := '******';
end;
实际使用时事件处理代码可根据需要来调整,用 Pos 当然也是可以的,Demo 中只是一个示例。
用这个事件除了可以处理密码,还可以用来为某些属性定制特殊的显示内容,比如日期格式、浮点数格式格式等。
PS: 之所以用增加事件的方法来解决这些问题,主要是这一类的需求可能很多,事件用起来虽然比较麻烦,但可以灵活控制。

刚才做了一下测试,发现还有问题:
在程序创建后密码还是以明文显示,编辑后或获得焦点离开后,密码才以*号显示。

可能跟事件定义顺序有关
如果你是动态关联事件的话,应该先关联事件,再设置Options属性。
