使用 IntraWeb (13) - 基本控件之 TIWLabel、TIWLink、TIWURL、TIWURLWindow

TIWLabel     //
TIWLink      //内部链接
TIWURL       //外部链接
TIWURLWindow //页内框架, 就是 <iframe></iframe>

TIWLabel 所在单元及继承链:
IWCompLabel.TIWLabel

主要成员:

---

property AutoSize: Boolean       //自动大小
property Caption: TCaption       //使用 Text 也行
property RawText: Boolean        //= True 时, 会把 Caption 当做 Html 源代码
property ConvertSpaces: Boolean  //是否转换空格; 如果 False, 连续的空格只能被识别为一个
property NoWrap: Boolean         // = False 且 ConvertSpaces = False 且 AutoSize = False 时, 可换行
property ForControl: TIWCustomControl  //指定它是哪个控件的标签; 指定后, 点击该 Label 会激活指定的控件

procedure TIWForm1.IWAppFormCreate(Sender: TObject);
