Subject: gtksearchenginetracker3: Pre-fill GFileInfo from query
X-Git-Tag: archive/raspbian/4.4.1+ds1-2+rpi1^2~18^2~16^2~145^2~1
X-Git-Url: https://dgit.raspbian.org/?a=commitdiff_plain;h=edf6f9e108a3375f386679c25e872d95aa449a8b;p=gtk4.git

gtksearchenginetracker3: Pre-fill GFileInfo from query

Provide the minimal info necessary. Improves apparent responsiveness
(since we don't visibly clear and repopulate the list) and saves doing
file stat/reads on every file in the result set.
