Description
Draws a rectangle in the style used to indicate that the object inside the rectangle has focus.
Override the DrawFocusRect method to implement drawing of a focused rectangle. DrawFocusRect is called for the perimeter of the image of a control when the control gets or loses input focus. Because DrawFocusRect uses an XOR function, calling it a second time while specifying the same rectangle removes the rectangle from the screen.
