TIWList //列表; 它对应 Html 中的 OL、LI(某些选项下会用表格模拟); TIWListbox 和 TIWComboBox 则对应 Html 在的 Option TIWListbox //列表框 TIWComboBox //组合下拉框 TIWOrderedListbox //可手动调整顺序的列表; 好像是新增的, 还不成熟
TIWList 所在单元及继承链:

主要成员:
property Items: TStringList // property Numbered: Boolean //是否使用数字编号; 默认 True property Bulleted: Boolean //是否使用项目符号; 默认 False property BulletType: TIWListBulletType //项目符号类型: btDisc(默认)、btCircle、btSquare、btNone property RenderMode: TIWListRenderMode //最终在 Html 中的呈现方式: rmTable(使用表格)、rmHTMLList(使用 Html 标准列表); 默认是 rmTable, 我推荐后者 procedure Clear //
