source: abuse/trunk/src/console.cpp @ 112

Last change on this file since 112 was 106, checked in by Sam Hocevar, 11 years ago
  • Rename the "eh" variable to "wm" because it's a window manager, not an event handler.
  • No longer pass the window manager to functions, there's only one.

Inspired by Win32 Abuse changelog for January 28, 2001:

  • Starting work on singleton code; will get rid of all

references to an arbitrary window_manager* because
there's only going to be one, and it's not ever
going to change.
