注釈

DesignerOptionServiceクラスには、オプションのコレクションが用意されています。The DesignerOptionService class provides a collection of options. これらのオプションのコレクションのそれぞれで、さらにフィルター処理することができるインデクサーがあります。Each of these option collections has an indexer that enables it to be further filtered. 各オプションのコレクションには、独自のオプションのセットとその子のオプションのすべての更新プログラムのロールアップが含まれています。Each option collection contains its own set of options, as well as a rollup of all of its child options. プロパティの間の名前付けの競合が発生した場合は最も外側にあるオプションのオブジェクトが優先されます。In the event of a naming conflict between properties, the outermost options object takes precedence. ツール|オプション大きい重要度の最も外側にあるオプションのオブジェクトのユーザー インターフェイス (UI) の構造を示しています。The following Tools | Options user interface (UI) structure shows how the outermost options object takes on greater importance:

  • SnapToGridSnapToGrid

  • ShowGridShowGrid

  • GridSizeGridSize

指定された、IDesignerOptionServiceという名前serviceの値を取得するには、GridSizeプロパティでは、次の呼び出しになります。Given a IDesignerOptionService named service, to get to the value of the GridSize property, you would make the following call:

// Obtains and shows the size of the standard design-mode grid square.
System::Drawing::Size size =  *dynamic_cast<System::Drawing::Size^>(designerOptionService->GetOptionValue( "WindowsFormsDesigner\\General", "GridSize" ));
// Obtains and shows the size of the standard design-mode grid square.
Size size = (Size)designerOptionService.GetOptionValue("WindowsFormsDesigner\\General", "GridSize");
' Obtains and shows the size of the standard design-mode grid square.
Dim size As Size = CType(designerOptionService.GetOptionValue("WindowsFormsDesigner\General", "GridSize"), Size)

移動するまで、このしくみGridSize別のページにします。This works, until you want to move GridSize to another page. また、IDesignerOptionService検出メカニズムは提供されません。Also, IDesignerOptionService provides no discovery mechanism. 渡す文字列がわからない場合、サービスは、プロパティの値を見つけることができません。If you do not know what string to pass in, the service cannot find the property value.

DesignerOptionServiceクラスがこうした問題に対処します。The DesignerOptionService class addresses these issues. コレクション、クエリを実行することができで定義されている型コンバーターが、DesignerOptionService.DesignerOptionCollectionとして展開可能なコレクションをマークするオブジェクト。You can query collections, and there is a type converter defined on the DesignerOptionService.DesignerOptionCollection object that marks the collection as expandable. この型コンバーターをプロパティ ウィンドウに、デザイナーのオプションが全体のサービスを渡すでき、視覚的なサービスを調査できます。With this type converter, you can pass the entire designer option service to a property window and visually inspect the service.
