注釈

TabRendererクラスのセットを提供するstaticオペレーティング システムの現在の visual スタイルでタブ コントロールを表示するために使用できるメソッド。The TabRenderer class provides a set of static methods that can be used to render a tab control with the current visual style of the operating system. コントロールのレンダリングとは、コントロールのユーザー インターフェイスを描画することを意味します。Rendering a control refers to drawing the user interface of a control. これは、現在の visual スタイルの外観を持つカスタム コントロールを描画する場合に便利です。This is useful if you are drawing a custom control that should have the appearance of the current visual style. タブ コントロールを描画するために使用して、DrawTabPageメソッドは、ページの描画を使用して、DrawTabItem各タブを描画するメソッド。To draw a tab control, use the DrawTabPage method to draw the page, and use the DrawTabItem method to draw each tab.

オペレーティング システムで visual スタイルが有効になっている、アプリケーション ウィンドウのクライアント領域に visual スタイルが適用される場合は、このクラスのメソッドは現在の visual スタイルを持つタブ コントロールを描画します。If visual styles are enabled in the operating system and visual styles are applied to the client area of application windows, the methods of this class will draw the tab control with the current visual style. このクラスのプロパティとメソッドがスローされます、それ以外の場合、InvalidOperationExceptionします。Otherwise, the methods and properties of this class will throw an InvalidOperationException. このクラスのメンバーを使用できるかどうかを判断するには、値を確認、IsSupportedプロパティ。To determine whether the members of this class can be used, check the value of the IsSupported property.

このクラスの機能をラップする、System.Windows.Forms.VisualStyles.VisualStyleRendererによって公開されている要素のいずれかに設定されている、System.Windows.Forms.VisualStyles.VisualStyleElement.Tabクラス。This class wraps the functionality of a System.Windows.Forms.VisualStyles.VisualStyleRenderer that is set to one of the elements exposed by the System.Windows.Forms.VisualStyles.VisualStyleElement.Tab class. 詳細については、次を参照してください。 Visual スタイルを使用しているコントロールのレンダリングします。For more information, see Rendering Controls with Visual Styles.
