This sample demonstrates how to handle the user input events of the UIElement class in order to implement touch, mouse, stylus, and keyboard support in your app.

Specifically, this sample covers:

• Handling the PointerPressed, PointerMoved, and PointerReleased events implement a drawing feature.
• Handling the PointerEntered and PointerExited events to change the visual state of an element.
• Using the CapturePointer and ReleasePointerCapture methods.
• Handling the Tapped, DoubleTapped, RightTapped, and Holding events.
• Handling manipulation events to implement drag, zoom, and rotate gestures.
• Handling the KeyDown and KeyUp events.

Important  Mouse input is associated with a single pointer assigned when mouse input is first detected. Clicking a mouse button (left, wheel, or right) creates a secondary association between the pointer and that button through the PointerPressed event. The PointerReleased event is fired only when that same mouse button is released (no other button can be associated with the pointer until this event is complete). Because of this exclusive association, other mouse button clicks are routed through the PointerMoved event.
