Description
Draws a rectangle in the style used to indicate that the object inside the rectangle has focus.
Call DrawFocusRect for the perimeter of a control's image 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.
The rectangle drawn by this function cannot be scrolled. To scroll an area containing a rectangle drawn by DrawFocusRect, call DrawFocusRect to remove the rectangle from the screen, scroll the area, and then call DrawFocusRect to draw the rectangle in the new position.
Warning: DrawFocusRect raises an exception. TDirect2DCanvas does not support the DrawFocusRect operation.
