KeyboardCapabilities 類別

定義

命名空間:

Windows.Devices.Input

提供判斷任何已連線硬體鍵盤功能的能力。

public ref class KeyboardCapabilities sealed

/// [Windows.Foundation.Metadata.ContractVersion(Windows.Foundation.UniversalApiContract, 65536)]
/// [Windows.Foundation.Metadata.MarshalingBehavior(Windows.Foundation.Metadata.MarshalingType.Agile)]
/// [Windows.Foundation.Metadata.Activatable(65536, "Windows.Foundation.UniversalApiContract")]
class KeyboardCapabilities final

[Windows.Foundation.Metadata.ContractVersion(typeof(Windows.Foundation.UniversalApiContract), 65536)]
[Windows.Foundation.Metadata.MarshalingBehavior(Windows.Foundation.Metadata.MarshalingType.Agile)]
[Windows.Foundation.Metadata.Activatable(65536, "Windows.Foundation.UniversalApiContract")]
public sealed class KeyboardCapabilities

function KeyboardCapabilities()

API contract	Windows.Foundation.UniversalApiContract (已於 v1.0 引進)

備註

裝置功能範例示範如何偵測輸入裝置是否存在，以及擷取每個裝置的功能和屬性。

下列程式碼示範如何建立這個類別的實例，並用它來判斷鍵盤是否存在。

function getKeyboardCapabilities() {
  var keyboardCapabilities = new Windows.Devices.Input.KeyboardCapabilities();
  id("keyboardPresent").innerHTML = keyboardCapabilities.keyboardPresent;
}

建構函式

KeyboardCapabilities()

初始化 KeyboardCapabilities 類別的新實例。

屬性

KeyboardPresent

取得值，指出是否偵測到裝置將本身識別為鍵盤。
