使用 IntraWeb (21) - 基本控件之 TIWTabControl
TIWTabControl 包含的是 TIWTabPage; 设计时通过右键菜单 Add Page 添加(再给页面添加东西时一定要先选定页面); 下面例子是动态添加的.
TIWTabControl 所在单元及继承链:
IWCompTabControl.TIWTabControl < TIWCustomRegion < TIWHTML40Container < TIWHTMLContainer < TIWContainer < TIWBaseContainer < TScrollingWinControl < TWinControl < TControl < TComponent < TPersistent < TObject
主要成员:
property Pages: TList //TIWTabPage 对象的集合; 但它是 TList 类型, 使用前需转换下 property ActiveTabFont: TIWFont //当前 Tab 标签的字体 property ActiveTabColor: TIWColor //当前 Tab 标签的背景色 property InactiveTabFont: TIWFont //其他 Tab 标签的字体 property InactiveTabColor: TIWColor //其他 Tab 标签的背景色 property ActivePage: Integer //当前页号; 如果需要设置它将导致提交, 官方给出了通过 js 进行本地设置的方法: IWTABCONTROL1.tabPane.setSelectedIndex(i); property BorderOptions: TIWContainerBorderOptions //它的边框选项还是比较复杂的, 个人觉得: 如果需要边框还不如套个 TIWRegion property LayoutMgr: TIWContainerLayout //布局管理器, 它也可以用模板(它是从 TIWCustomRegion 继承的) property Color: TIWColor // property OnChange: TNotifyEvent // property OnAsyncChange: TIWAsyncEvent // procedure Submit(const AValue: string) // procedure pageAdded(APage: TIWTabPage) // procedure pageRemoved(APage: TIWTabPage) // function CreateNewPage(const APageTitle: string; const APageName: string): TIWTabPage //
TIWTabPage:
{IWCompTabControl.TIWTabPage < TIWCustomRegion < TIWHTML40Container < TIWHTMLContainer < TIWContainer < TIWBaseContainer < TScrollingWinControl < TWinControl < TControl < TComponent < TPersistent < TObject} property Title: string // property Color: TIWColor // property BorderOptions: TIWContainerBorderOptions // procedure Invalidate //
测试:
{先在空白窗体上放 1 个 TIWTabControl, 3 个 TIWTabPage, 2 个 TIWButton} procedure TIWForm1.IWAppFormCreate(Sender: TObject); var fPage1, fPage2, fPage3: TIWTabPage; begin //动态建立 3 个 TIWTabPage fPage1 := IWTabControl1.CreateNewPage(' Page1 '); fPage2 := IWTabControl1.CreateNewPage(' Page2 '); fPage3 := IWTabControl1.CreateNewPage(' Page3 '); //让 IWButton1 具备切换标签的功能 JavaScript.Add('var i = 0;'); //js 全局变量 IWButton1.ScriptEvents.HookEvent('onclick', 'i++; i%=3; IWTABCONTROL1.tabPane.setSelectedIndex(i);'); //IWTABCONTROL1 或换成 IWTABCONTROL1IWCL IWTabControl1.Color := $efefef; IWTabControl1.InactiveTabColor := $efefef; IWTabControl1.ActiveTabColor := $0000ff; IWGrid1.Parent := fPage1; IWGrid2.Parent := fPage2; IWGrid3.Parent := fPage3; IWGrid1.RowCount := 3; IWGrid1.ColumnCount := 4; IWGrid1.BGColor := $ffeeee; IWGrid1.CellPadding :=4; IWGrid1.Align := alTop; IWGrid2.RowCount := 4; IWGrid2.ColumnCount := 5; IWGrid2.BGColor := $eeeeff; IWGrid2.CellPadding := 4; IWGrid2.Align := alTop; IWGrid3.RowCount := 5; IWGrid3.ColumnCount := 6; IWGrid3.BGColor := $eeffee; IWGrid3.CellPadding := 4; IWGrid3.Align := alTop; end; {测试 Pages 属性} procedure TIWForm1.IWButton2Click(Sender: TObject); begin WebApplication.ShowMessage(TIWTabPage(IWTabControl1.Pages[0]).Title); // Page1 end;
效果图:
