Public NotInheritable Class TouchCapabilities

Inheritance: Object Platform::Object IInspectable TouchCapabilities

Attributes: ActivatableAttribute ContractVersionAttribute MarshalingBehaviorAttribute

Windows requirements

Device family	Windows 10 (introduced in 10.0.10240.0)
API contract	Windows.Foundation.UniversalApiContract (introduced in v1.0)

Remarks

The values returned by the properties discussed here are based on the total number of touch digitizers connected: Boolean properties return true if one digitizer supports a specific capability and numeric properties return the maximum value exposed by all digitizers.

The Device Capabilities Sample demonstrates how to detect the presence of input devices and retrieve the capabilities and attributes of each device.

The following code shows how to use this class to determine touch capabilities.

function getTouchCapabilities() {
    var touchCapabilities = new Windows.Devices.Input.TouchCapabilities();
    id("contacts").innerHTML = touchCapabilities.Contacts;
}

Constructors

TouchCapabilities()

Initializes a new instance of the TouchCapabilities class.

Properties

Contacts	Gets the minimum number of contacts supported by all the digitizers.
TouchPresent	Gets a value that indicates whether a touch digitizer is detected.
