次のコード例は、使用するカスタム コントロールを作成する方法を示します、DrawButtonボタンを描画するメソッド。The following code example demonstrates how to create a custom control that uses the DrawButton method to draw a button. ボタンがクリックされた、コントロールが元のボタンの境界内の小さいボタンを描画し、コントロールを使用して、DrawParentBackground元のボタンの残りの部分を描画するメソッド。When the button is clicked, the control draws a smaller button inside the bounds of the original button, and the control uses the DrawParentBackground method to paint over the rest of the original button.

ButtonRendererクラスのセットを提供するstaticボタン コントロールを表示するために使用できるメソッド。The ButtonRenderer class provides a set of static methods that can be used to render a button control. 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. ボタンを描画するのいずれかの操作を使用して、DrawButtonメソッド。To draw a button, use one of the DrawButton methods. これらのメソッドは、さまざまな描画テキストやボタンの画像などのオプションを提供します。These methods provide a variety of options, such as drawing text or an image on the button.

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て、現在のアプリケーションに visual スタイルが適用DrawButton現在の visual スタイルでボタンを描画します。If visual styles are enabled in the operating system and visual styles are applied to the current application, DrawButton will draw the button with the current visual style. それ以外の場合、DrawButtonクラシック Windows スタイルでボタンを描画します。Otherwise, DrawButton will draw the button with the classic Windows style. これは、オペレーティング システムの現在の visual スタイルの設定を自動的に一致する必要があるカスタム 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 automatically match the current visual style setting of the operating system.
