public virtual System.Windows.Forms.AccessibleObject HitTest (int x, int y);
public virtual System.Windows.Forms.AccessibleObject? HitTest (int x, int y);
abstract member HitTest : int * int -> System.Windows.Forms.AccessibleObject

Public Overridable Function HitTest (x As Integer, y As Integer) As AccessibleObject
Parameters
- x
- Int32
The horizontal screen coordinate.
- y
- Int32
The vertical screen coordinate.
Returns
An AccessibleObject that represents the child object at the given screen coordinates. This method returns the calling object if the object itself is at the location specified. Returns null
if no object is at the tested location.
Exceptions
The control cannot be hit tested.
Remarks
For nonrectangular objects such as list view items, the coordinates of the object's bounding rectangle retrieved by Bounds can fail if tested with HitTest, because HitTest determines the object's boundaries on a pixel-by-pixel basis.
Notes to Inheritors
All visual objects must support this method; sound objects do not support it.
