移動 UI 自動化項目
![]() |
---|
這份文件適用於想要使用 System.Windows.Automation 命名空間中定義之 Managed UI Automation 類別的 .NET Framework 開發人員。如需 UI Automation 的最新資訊,請參閱 Windows Automation API:使用者介面自動化 (英文)。 |
本範例示範如何將 UI Automation項目移至指定的畫面位置。
範例
下列範例使用 WindowPattern 和 TransformPattern 控制項模式,以程式設計方式將 Win32 目標應用程式移到不連續的畫面位置,並追蹤 BoundingRectangleProperty AutomationPropertyChangedEvent。
