I suppose you want to code something similar to the "window always on top"
setting
available in various applications.

For this, use SetWindowPos() in place of BringWindowToTop().
Try to convert the following C code to Ruby (using Win32API):

SetWindowPosl(hwnd, HWND_TOPMOST, 0, 0, 0, 0, SWP_NOSIZE|SWP_NOMOVE)

To disable the "always on top" feature:

SetWindowPosl(hwnd, HWND_NOTOPMOST, 0, 0, 0, 0, SWP_NOSIZE|SWP_NOMOVE)

(see

for more details about this function)
