使用 IntraWeb (25)

這應該是 IW 中最重要的容器了, 和它同父的還有 TIWTabControl

TIWRegion 所在單元及繼承鏈:
IWRegion.TIWRegion < TIWCustomRegion < TIWHTML40Container < TIWHTMLContainer < TIWContainer < TIWBaseContainer < TScrollingWinControl < TWinControl < TControl < TComponent < TPersistent < TObject

主要成員:

---

property Align: TAlign
property Anchors: TAnchors
property BorderOptions: TIWContainerBorderOptions //設置邊框的寬度、顏色、樣式
property Color: TIWColor
property ClipRegion: Boolean           //對應 CSS clip, 如果控件大於區域, 是否剪切; 默認 True
property LayoutMgr: TIWContainerLayout //要套用的布局管理器
property Splitter: Boolean	       //是否提供分割線; 它出現的位置與 Align 屬性有關系
property StyleRenderOptions: TIWStyleRenderOptions
property Visible: Boolean
property DoRefreshControl: Boolean
property InternalTabOrder: TTabOrder
property ContainerContext: TIWContainerContext 
property IWComponentsCount: Integer
property RenderInvisibleControls: Boolean //是否呈現隱藏的控件; 默認 False
property HorzScrollBar: TControlScrollBar
property VertScrollBar: TControlScrollBar

property OnCreate: TNotifyEvent
property OnRender: TNotifyEvent

procedure SetBounds(ALeft: Integer; ATop: Integer; AWidth: Integer; AHeight: Integer)
procedure Invalidate
function OwnerForm: TIWBaseForm
function OwnerFrame: TIWHTMLContainer
procedure Freeing(AObject: TObject)
procedure ForceAlign
procedure DisableAutoRange
procedure EnableAutoRange
procedure ScrollInView(AControl: TControl)

RenderInvisibleControls 屬性測試:

---

procedure TIWForm1.IWAppFormCreate(Sender: TObject);
begin
  IWRectangle1.Visible := False;             //假如 IWRectangle1 在 IWRegion1 內, 並且已經隱藏了
  IWRegion1.RenderInvisibleControls := True; //如果不指定 RenderInvisibleControls := True 那麼再從異步事件中設置 IWRectangle1.Visible := True 將無效
end;

{OnAsyncClick}
procedure TIWForm1.IWButton1AsyncClick(Sender: TObject; EventParams: TStringList);
begin
  IWRectangle1.Visible := not IWRectangle1.Visible;
end;

---

Splitter 屬性測試:

---

{先放三個互不嵌套的 TIWRegion}
procedure TIWForm1.IWAppFormCreate(Sender: TObject);
begin
  IWRegion1.Color := $ff0000;
  IWRegion2.Color := $0000ff;
  IWRegion3.Color := $00ff00;

  IWRegion1.Align := alTop;
  IWRegion2.Align := alLeft;
  IWRegion3.Align := alClient;

  IWRegion1.Splitter := True;
  IWRegion2.Splitter := True;
end;
