system_window

System window constants.

struct system_window
{
 enum
 {
  desktop=0,
  top=0,
  bottom=1,
  topmost=-1,
  last=-1,
  no_topmost=-2,
  message=-3,
  broadcast = 0xffff
 };
};

Notes

This structure contains constants that represent (in various situations) windows in the system. To create an instance of a class containing one of the constants, the constant should be cast to a handle. The resultant window handle may then be used for the required purpose.
