Remarks

You can create a gesture object for each appropriate element when your app starts. However, this approach might not scale well depending on the number of gesture objects you need to create (for example, a jigsaw puzzle with hundreds of pieces).

In this case, you can create gesture objects dynamically on a pointerdown event and destroy them on an MSGestureEnd event. This approach scales well, but does incur some overhead due to creating and releasing these objects.

Alternatively, you can statically allocate and dynamically manage a pool of reusable gesture objects.

Note

: This class is not agile, which means that you need to consider its threading model and marshaling behavior. For more info, see Threading and Marshaling (C++/CX) and Using Windows Runtime objects in a multithreaded environment (.NET).

For more detail on how to use cross-slide functionality, see Guidelines for cross-slide. The threshold distances used by the cross-slide interaction are shown in the following diagram.

Screen shot showing the select and drag and drop processes.

The PivotRadius and PivotCenter properties are used only when single pointer input is detected. They have no effect on multiple pointer input. The value for these properties should be updated regularly during the interaction.

Rotation is supported by a GestureRecognizer only when GestureSettings is set through the GestureSettings property.

Rotation is not supported for single pointer input if the value of PivotRadius is set to 0.

Examples

Here we set up a GestureRecognizer object with a collection of input event handlers for processing various pointer and gestures. For more information on how to listen to and handle Windows Runtime events, see .

Note

Use the target or currentTarget property of the event object instead of the GestureRecognizer object in the event handler.


// inputManager handles gesture recognition for this sample.
function inputManager(target) {
    // Initialize the gesture recognizer.
    var gr = new Windows.UI.Input.GestureRecognizer();

    // Visual feedback for pointer input is still displayed. 
    gr.showGestureFeedback = false;

    // Configure gesture recognizer to process the following:
    // double tap               - start questions and timer.
    // tap                      - move to next question.
    // right tap                - show answer.
    // hold and hold with mouse - start clues.

    // Register event listeners for these gestures.

   // Get intermediate PointerPoints

Remarks

If the value for AutoProcessInertia is set to false, applications must call ProcessInertia() to handle events during inertia.

CrossSlideExact CrossSlideExact CrossSlideExact CrossSlideExact

Gets or sets a value that indicates whether the exact distance from initial contact to end of the cross-slide interaction is reported.By default, a small distance threshold is subtracted from the first position reported by the system for cross-slide interactions. If this flag is set, the distance threshold is not subtracted from the initial position.

Note

This distance threshold is intended to account for any slight movement of the contact after initial detection. It helps the system differentiate between cross-sliding and panning, and helps ensure that a tap gesture is not interpreted as either.

Parameters
value

Returns

True if a UI element supports the double tap gesture and the time threshold to complete the gesture has not been crossed; otherwise false.

Attributes
Additional features and requirements
Device family
Windows 10 (introduced v10.0.10240.0)
API contract
Windows.Foundation.UniversalApiContract (introduced v1)

Remarks

This method supports GestureRecognizer object pool management, where GestureRecognizer objects are dynamically assigned to a set of UI elements.

Specifically, GestureRecognizer objects can be recycled for UI elements that do not support or can no longer process a double tap gesture. For example, if CanBeDoubleTap(PointerPoint) returns true for the most recent PointerPoint, it’s not safe to recycle the GestureRecognizer because a double tap is still a viable interaction based on subsequent input. If CanBeDoubleTap(PointerPoint) returns false, the GestureRecognizer can be safely recycled.

This method is not required if GestureRecognizer object pool management is not implemented.

Events

CrossSliding CrossSliding CrossSliding CrossSliding

Occurs when a user performs a slide or swipe gesture (through a single touch contact) within a content area that supports panning along a single axis only. The gesture must occur in a direction that is perpendicular to this panning axis.

Note

A swipe is a short sliding gesture that results in a selection action while the longer slide gesture crosses a distance threshold and results in a rearrange action. The swipe and slide gestures are demonstrated in the following diagram. Diagram showing the select and drag actions.

Remarks

Inertia is the tendency of an object to resist any change in its state of rest or its velocity.

This event is raised before inertia processing.

Inertia behavior for this manipulation can be customized in the handler for this event. For example, inertia can be set to end after a specific distance or UI is displayed.

Note

These settings cannot be customized after the event.
