资 源 简 介
This source code has been tested under OpenWindows 2.0, Sun s X11/NeWS
server. For Xlib programs that use KeyPress events you should either
(1) set the FocusLenience resource to `True , or (2) specifically notify
the window manager that you want to receive KeyPress/KeyRelease events
(but only in programs that need these events).
