Window.RestoreBounds プロパティ

定義

名前空間:

System.Windows

アセンブリ:

PresentationFramework.dll

最小化または最大化される前のウィンドウのサイズと位置を取得します。

public:
 property System::Windows::Rect RestoreBounds { System::Windows::Rect get(); };

public System.Windows.Rect RestoreBounds { [System.Security.SecurityCritical] get; }

public System.Windows.Rect RestoreBounds { get; }

[<get: System.Security.SecurityCritical>]
member this.RestoreBounds : System.Windows.Rect

member this.RestoreBounds : System.Windows.Rect

Public ReadOnly Property RestoreBounds As Rect

プロパティ値

Rect

最小化または最大化される前のウィンドウのサイズと位置を指定する Rect。

属性

SecurityCriticalAttribute

例

次の例では、ストレージを使用 RestoreBounds して分離し、ウィンドウのサイズと場所が以前のウィンドウと同じであることを確認します。

注釈

復元四角形は、ウィンドウが最小化または最大化する前に占める領域です。 アプリケーションを閉じる前にウィンドウの最後のサイズと場所を保存し、次回アプリケーションがウィンドウの復元を開始した時点で、ユーザーがウィンドウを離れた状態に戻す際に、それらの値を取得するために使用 RestoreBounds できます。

ウィンドウが表示される前または閉じられた後にクエリ RestoreBounds を実行した場合は、 Empty 返されます。

注意

ウィンドウがブラウザーでホストされている場合は、このプロパティを取得できません。
