UITypeEditor クラス
値エディタをデザインするために使用できる基本クラスを提供します。値エディタは、サポートされているデータ型のオブジェクトの値を表示および編集するためのユーザー インターフェイス (UI) を提供します。 名前空間: System.Drawing.Design

構文解説UITypeEditor クラスで提供される基本クラスから派生したクラスを拡張することによって、デザイン時の環境に合わせたカスタム型エディタを実装できます。カスタム型エディタは、テキスト ボックスの値エディタでは特定の型の値を効率よく選択できないような場合に役立ちます。
デザイン時に使用するカスタムの UI 型エディタを実装するには、次の手順を行う必要があります。
-
EditValue メソッドをオーバーライドし、ユーザー インターフェイス、ユーザーによる入力、および値の代入を処理できるようにします。
-
GetEditStyle メソッドをオーバーライドし、エディタが使用するエディタ スタイルの型をプロパティ ウィンドウに通知するようにします。
また、次の手順を実行することにより、値の視覚的な表現を [プロパティ] ウィンドウに描画する機能を追加できます。

デザイン時のサポートの拡張方法については、「デザイン時サポートの拡張」を参照してください。UITypeEditor の実装の詳細については、「ユーザー インターフェイス型エディタの概要」を参照してください。
使用例デザイン モードの [プロパティ] ウィンドウから角度選択インターフェイスを提供するために、EditorAttribute を使用して、UITypeEditor を整数、倍精度浮動小数点数、または浮動小数点プロパティに関連付けるコード例を次に示します。この例は、IWindowsFormsEditorService インターフェイスを使用して、デザイン モードの [プロパティ] ウィンドウにドロップダウン コントロールを表示します。コードをコンパイルしたら、Visual Studio の [ツール] メニューの [ツールボックス アイテムの追加と削除] を使用してアセンブリをツールボックスに追加します。エディタを使用してプロパティを構成するには、AngleTestControl のインスタンスを作成して、[プロパティ] ウィンドウの [Angle] プロパティの隣にあるドロップダウン ボタンをクリックします。
