From the GConf key description:
The window focus mode indicates how windows are activated. It has three possible values; "click" means windows must be clicked in order to focus them, "sloppy" means windows are focused when the mouse enters the window, and "mouse" means windows are focused when the mouse enters the window and unfocused when the mouse leaves the window.
When I configure focus_mode
using gconf-editor, /apps/metacity/general/focus_mode
, I can't tell the difference between mouse
and sloppy
.
When I set this key as mouse
, the focus is still on that window if I hover the cursor to the background.
The mouse mode will set focus on the desktop when the mouse hovers over a desktop area that has no open window, whereas the sloppy mode does not. The sloppy mode changes focus only if the mouse hovers over a window.
May be you can learn from this question:Focus Follows Mouse or Sloppy Focus on Mac OS X
