IPropertyValueUIService イベント
IPropertyValueUIService インターフェイス
アセンブリ: System.Drawing (system.drawing.dll 内)


コンポーネントでは、IPropertyValueUIService インターフェイスを使用することで、コンポーネントのすべてのプロパティに対して PropertyValueUIItem オブジェクトを提供できます。プロパティに関連付けられた PropertyValueUIItem では、イメージとツール ヒントの他に、プロパティに関連付けられたイメージがクリックされたときに発生するイベントのイベント ハンドラを提供できます。
IPropertyValueUIService インターフェイスは、内部リストに対して PropertyValueUIHandler デリゲートの追加、削除、および検索を行うメソッドを提供します。コンポーネントのプロパティがプロパティ ブラウザに表示されるときに、リスト中の各 PropertyValueUIHandler は、PropertyValueUIItem をコンポーネントの各プロパティに提供できます。
プロパティ ブラウザは、オブジェクトのプロパティを表示するように設定されると、コンポーネントの各プロパティごとに、プロパティを表す PropertyDescriptor を渡して、このインターフェイスの GetPropertyUIValueItems メソッドを呼び出します。GetPropertyUIValueItems メソッドは、サービスに追加されている各 PropertyValueUIHandler を呼び出します。各 PropertyValueUIHandler は、valueUIItemList パラメータで渡される PropertyValueUIItem を ArrayList パラメータに追加することによって、propDesc パラメータで渡される PropertyDescriptor が表すプロパティに対してそれらの UI 項目を提供します。
PropertyValueUIItem には、プロパティ名の横に表示するイメージ、ツール ヒント文字列、およびプロパティに関連付けられたイメージがダブルクリックされたときに呼び出されるイベント ハンドラを格納できます。

次のコード例では、IPropertyValueUIService インターフェイスのインスタンスを取得するコンポーネントを作成します。このコンポーネントは、取得したサービスに PropertyValueUIHandler を追加します。追加されたこのハンドラは、コンポーネントに含まれているプロパティのうち、 HorizontalMargin または VerticalMargin という名前のすべてのプロパティに対して、PropertyValueUIItem オブジェクトを提供します。なお、この PropertyValueUIItem は、対象のプロパティにイメージとツールヒントを提供するだけでなく、それらのプロパティのイメージがクリックされたときにメッセージ ボックスを表示するイベント ハンドラも提供します。イメージとツールヒントは、これらのプロパティが PropertyGrid に表示されているときに表示されます。
