| BOOL DrawFocusRect(hdc, lprc) | |||||
| HDC hdc; | /* handle of device context | */ | |||
| CONST RECT *lprc; | /* address of structure with rectangle | */ | |||
This function draws a rectangle in the style used to indicate focus.
hdc
Identifies the device context.
lprc
Points to a RECT structure that specifies the coordinates of the rectangle to be drawn.
FALSE on error, TRUE on success
Since this is an XOR function, calling this function a second time with the same rectangle removes the rectangle from the display.
The rectangle drawn by this function cannot be scrolled. To scroll an area containing a rectangle drawn by this function, call DrawFocusRect to remove the rectangle from the display, scroll the area, and then call DrawFocusRect to draw the rectangle in the new position.
