[−][src]Function ncursesw::overlay
pub fn overlay(
src_handle: WINDOW,
dst_handle: WINDOW
) -> Result<(), NCurseswError>
Overlay the window on top of destwin
. The windows need not be the same size,
only the overlapping region is copied. This copy is non-destructive, which
means that the current background character does not overwrite the old
contents of destwin.
To get fine-grained control over the copied region, the second form of
overlay()
can be used. sminrow and smincol are the upper-left coordinates
of the source window, and the other variables mark a rectangle in the
destination window.
