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

TIWLabel    // TIWLink      //内部连接 TIWURL      //外部连接 TIWURLWindow //页内框架, 就是 <iframe></iframe>

---

TIWLabel 所在单元及继承链:
IWCompLabel.TIWLabel < TIWCustomLabel < TIWCustomControl < TIWBaseHTMLControl < TIWBaseControl < TIWVCLBaseControl < TControl < TComponent < TPersistent < TObject

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 当作 Html 源代码 property ConvertSpaces: Boolean  //是否转换空格; 若是 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  //指定它是哪一个控件的标签; 指定后, 点击该 Label 会激活指定的控件

RawText 属性测试:
