Subject: views: Initial implementation of win.setParentWindow(parent)
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=473413e874132eac838471b55289a383d75de811;p=platform%2Fframework%2Fweb%2Fcrosswalk-tizen.git

But it doesn't work, aparrently Chromium doesn't support changing
parent window dynamically on desktop.
