TIWHRule //一条横线, 对应 Html 中的 <hr/> 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
示例:
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;
