Subject: Implemented text field for filtering the friend list
X-Git-Tag: v2.0b-1~61^2^2~26
X-Git-Url: https://vcs.maemo.org/git/?a=commitdiff_plain;h=ba0ae5323f3e1fad87473d14ee4da2c6b085d9eb;p=situare

Implemented text field for filtering the friend list

 - the field grabs the keyboard, so all keypresses modify the
   field even if it is not focused

 - the field is hidden by default, and is invoked when a key
   is pressed.

 - the field is hidden when it is empty (for example when cleared
   by using the backspace)

 - the field is cleared (and thus hidden) when return/enter is
   pressed
