From 98fa27c4c992dacae93cb127319271c87a9c2363 Mon Sep 17 00:00:00 2001 From: Liming An Date: Thu, 22 Mar 2012 19:08:40 +0800 Subject: [PATCH] Hob: add auto scroll to rows which be new appended in hob building log page For make the building screen to provide clear information about task in progress by request, so add this function. At the beginning of building, the vertical scroll bar will go to the active area automatically. Once the user moves the scroll bar in the middle, the automatic move of the bar is disabled. However, once the user moves it to the bottom again, it will be kept to the bottom even though more logs come.
