Public Overridable Function HitTest (x As Integer, y As Integer) As AccessibleObject
- x
- Int32
The horizontal screen coordinate.
- y
- Int32
The vertical screen coordinate.
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.
The control cannot be hit tested.
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.
All visual objects must support this method; sound objects do not support it.
