TIWHRule    //一条横线, 对应 Html 中的 
    
 TIWRectangle //矩形; 中间可以有行文本, 文本可任意对齐

TIWHRule 所在单元及继承链:

IWHTMLControls.TIWHRule < TIWCustomControl < TIWBaseHTMLControl < TIWBaseControl < TIWVCLBaseControl < TControl < TComponent < TPersistent < TObject

它没什么特别的成员, 下面是通过样式表把它改成红线:

---

procedure TIWForm1.IWAppFormCreate(Sender: TObject); begin   IWHRule1.Width := Width div 2;   IWHRule1.Height := 3;   IWHRule1.Left := (Width - IWHRule1.Width) div 2;   IWHRule1.Top := 60;   IWHRule1.Anchors := [akLeft, akTop, akRight]; end; procedure TIWForm1.IWHRule1HTMLTag(ASender: TObject; ATag: TIWHTMLTag); begin   ATag.Params.Values['style'] := ATag.Params.Values['style'] + 'background-color: red; border:0;'; end;

TIWRectangle 所在单元及继承链:

IWCompRectangle.TIWRectangle < TIWCustomRectangle < TIWCustomControl < TIWBaseHTMLControl < TIWBaseControl < TIWVCLBaseControl < TControl < TComponent < TPersistent < TObject

主要成员:

---

property BorderOptions: TIWBorderOptions //边框选项; 主要是 Width 和 Color property Color: TIWColor                //矩形的颜色 property Alignment: TAlignment          //文本水平对齐方式 property VAlign: TIWVerticalAlignment    //文本垂直对齐方式 property Text: TCaption                  //文本

procedure TIWForm1.IWAppFormCreate(Sender: TObject); begin   IWRectangle1.BorderOptions.Width := 1;   IWRectangle1.BorderOptions.Color := $0000FF;   IWRectangle1.Color := $F0E0E0;   IWRectangle1.Text := '万一的 Delphi 博客';   IWRectangle1.Font.Color := $0000FF;   IWRectangle1.Font.Size := 16;   IWRectangle1.Alignment := taCenter;   IWRectangle1.VAlign := vaMiddle; end;
