Hello,
I asked this question once before but not very articulately. Then I then
went on vacation and moved on to other issues. Anyway, back to the
original question:
Correct me if I'm wrong, but if I have a window, the root window, that is
currently displaying and takes up the entire display, and I then perform
the following operations:
// ...
<Do lots of drawing on the root window until...>
// ...
// Create and open a NEW window whose PARENT is the ROOT window.
windowID = GrNewWindow(GR_ROOT_WINDOW_ID, 0, 0, SCREEN_WIDTH,
SCREEN_HEIGHT, 0, GR_COLOR_WHITE, GR_COLOR_WHITE);
// Map (show) the window.
GrMapWindow(windowID);
<draw some stuff>
// Remove this window.
GrUnmapWindow(windowID);
GrDestroyWindow(windowID);
...then at this point, should the contents of the root window not be
redisplayed? Please forgive my naïveté, but do I have to use the window
manager (nanowm) to make this happen?
