DrawFocusRect
The DrawFocusRect
function draws a rectangle in the style used to indicate that the rectangle has
the focus.
BOOL DrawFocusRect(
|
HDC hDC, |
// handle to device
context |
|
CONST RECT *lprc |
// pointer to
structure for rectangle |
|
); |
|
Parameters
hDC
Identifies
the device context.
lprc
Points to a RECT structure that specifies
the logical coordinates of the rectangle.
Return Values
If the
function succeeds, the return value is nonzero.
If the
function fails, the return value is zero. To get extended error information,
call GetLastError.
Remarks
Because DrawFocusRect
is an XOR function, calling it a second time with the same rectangle removes
the rectangle from the screen.
This function
draws a rectangle that cannot be scrolled. To scroll an area containing a
rectangle drawn by this function, call DrawFocusRect to remove the
rectangle from the screen, scroll the area, and then call DrawFocusRect
again to draw the rectangle in the new position.
