Editing Focus (computing) (section)

==Window focus==
The behaviour of focus on one's desktop can be governed by policies in [[Window manager|window management]].

===Click to focus===
On most mainstream user-interfaces, such as ones made by [[Microsoft]] and [[Apple Inc.|Apple]], it is common to find a "focus follows click" policy (or "click to focus"), where one must click the mouse inside of the window for that window to gain focus. This also typically results in the window being raised above all other windows on screen. If a '''clickfocus''' model such as this is being used, the current application window continues to retain focus and collect input, even if the mouse pointer is over another application window.

===Focus follows pointer===
Another common policy on [[Unix]] systems using [[X Window System]] (X11) is the "focus follows mouse" policy (or FFM), where the focus automatically follows the current placement of the pointer. The focused window is not necessarily raised; parts of it may remain below other windows. Window managers with this policy usually offer "autoraise," which raises the window when it is focused, typically after a configurable short delay. A possible consequence of a '''followfocus''' policy is that no window has focus when the pointer is moved over the background with no window underneath; otherwise the focus simply remains in the last window.

===Sloppy focus===
The '''sloppyfocus''' model is a variant of the followfocus model.<ref>{{cite web|title=Sloppy Focus|url=http://c2.com/cgi/wiki?SloppyFocus|website=c2.com/cgi/wiki|date=25 February 2012}}</ref> It allows input to continue to be collected by the last focused window when the mouse pointer is moved away from any window, such as over a menubar or desktop area.
