UIElement.InputHitTest Method

Returns the input element within the current element that is at the specified coordinates, relative to the current element's origin.

Namespace:  System.Windows
Assembly:  PresentationCore (in PresentationCore.dll)

public IInputElement InputHitTest(
	Point point
)

Parameters

point
Type: System.Windows.Point

The offset coordinates within this element.

Return Value

Type: System.Windows.IInputElement
The element child that is located at the given position.

IInputElement is returned as the return type, because that type is a common interface for both UIElement and ContentElement. You can then cast the return type appropriately, or use the interface instance for certain members that are defined by the IInputElement interface.

This method typically is not called from your application code. Calling this method is only appropriate if you intend to re-implement a substantial amount of the low level input features that are already present, such as recreating mouse device logic.

IContentHost contracts an InputHitTest method with the same signature, which some elements choose to implement explicitly.
