public:
property bool CanResize { bool get(); };
public bool CanResize { get; }
member this.CanResize : bool
Public ReadOnly Property CanResize As Boolean
プロパティ値
要素のサイズを変更できる場合は true
。変更できない場合は false
。true
if the element can be resized; otherwise false
.
例
次の例TransformPatternでは、コントロールパターンをAutomationElementから取得し、その後、のAutomationElementサイズを変更するために使用します。In the following example, a TransformPattern control pattern is obtained from an AutomationElement and subsequently used to resize the AutomationElement.

注釈
オブジェクトを移動、サイズ変更、または回転することはできません。その結果、画面の位置がコンテナーの座標の外側になり、キーボードやマウスでアクセスできなくなります。An object cannot be moved, resized, or rotated such that its resulting screen location would be completely outside the coordinates of its container and inaccessible to keyboard or mouse. たとえば、最上位レベルのウィンドウが画面外に移動した場合や、子オブジェクトがコンテナーのビューポートの境界の外側に移動された場合などです。For example, when a top-level window is moved completely off-screen or a child object is moved outside the boundaries of the container's viewport. このような場合、オブジェクトは、最上位または左の座標がコンテナーの境界内でオーバーライドされ、要求された画面座標の近くに配置されます。In these cases the object is placed as close to the requested screen coordinates as possible with the top or left coordinates overridden to be within the container boundaries.
