GraphicsPath.Clone メソッド

定義

このパスの同一コピーを作成します。Creates an exact copy of this path.

public:
 virtual System::Object ^ Clone();
public object Clone ();
abstract member Clone : unit -> obj
override this.Clone : unit -> obj
Public Function Clone () As Object

戻り値

Object

このメソッドが作成し、オブジェクトとしてキャストされる GraphicsPathThe GraphicsPath this method creates, cast as an object.

実装

次のコード例は、Windows フォームで使用するように設計されており、イベントオブジェクトを必要とし PaintEventArgs e OnPaint ます。The following code example is designed for use with Windows Forms, and it requires PaintEventArgse, an OnPaint event object. コードは、次のアクションを実行します。The code performs the following actions:

  • パスを作成します。Creates a path.

  • パスに複数の図形を追加します。Adds several figures to the path.

  • 画面へのパスを描画します。Draws the path to the screen.

  • そのパスのコピーを複製します。Clones a copy of that path.

  • 画面に新しいパスを描画します。Draws the new path to the screen.

メソッドの呼び出しは Clone 、としてキャストする必要があることに注意して GraphicsPath ください。Notice that the call the Clone method must be cast as a GraphicsPath.
