Subject: viewSelector: clean up active search state code
X-Git-Tag: archive/raspbian/50.5-1+rpi1~1^2~1013^2^2~5035
X-Git-Url: https://dgit.raspbian.org/%22http://www.example.com/cgi/%22/%22http:/www.example.com/cgi/%22?a=commitdiff_plain;h=4bd071bf3c2b0273e557db7614ab061a4d1627c1;p=gnome-shell.git

viewSelector: clean up active search state code

'active' isn't terribly clear about just what is active; also, make it
private, remove an useless extra object state we were saving, and
refactor some messy code.
Based on a patch by Tanner Doshier.
