From: Andrew den Exter Date: Thu, 10 Nov 2011 04:19:32 +0000 (+1000) Subject: Create a copy of QLineControl in the QtDeclarative library. X-Git-Url: http://git.silmor.de/gitweb/?a=commitdiff_plain;h=3f83388dba250778a265c4c6c35bd32679123832;p=konrad%2Fqtdeclarative.git Create a copy of QLineControl in the QtDeclarative library. First half of a move of QLineControl from qtbase to qtdeclarative, some time in the future QLineControl will be deleted from qtbase to finish the move.
