39217 2010-05-17 07:06:06 -0700 Add an optional "starting node' parameter to scrollRecursively and scrollOverflow of EventHandler 2011-04-19 05:15:29 -0700 1 1 1 Unclassified WebKit WebCore Misc. 528+ (Nightly build) PC All CLOSED FIXED P2 Enhancement --- 18662 39195 1 tonikitoo tonikitoo abarth darin eric hausmann webkit.review.bot oldest_to_newest 226750 0 tonikitoo 2010-05-17 07:06:06 -0700 It would be useful if scrollOverflow and scrollRecursively methods of EventHandler had an optional parameter to be the starting point of a scroll action. For example, currently, EventHandler::scrollOverflow starts a scrolling off of either a 'focusedNode' of a m_'mousePressNode' (see below): bool EventHandler::scrollOverflow(...) { Node* node = m_frame->document()->focusedNode(); if (!node) node = m_mousePressNode.get(); (...) but it would be useful, for Spatial Navigation purposes, that we could pass a Node for the scrolling to start from. scenario (see illustration below): 1) a focused node called "focused", an overflow div (with a clipped overflow focusable node called "offscreen"); 2) user presses key down. 3) Focus should move to "offscreen", but since it is clipped overflow, spatial navigation will scroll-in-direction until it gets visible. -------------------------------- ********* *focused* ********* vertically overflowed div ******************** * * * * * * * * * * * * ******************** . . . *offscreen* . -------------------- -------------------------------- In order to scroll the overflowed div, it is needed to pass to EventHandler::scrollOverflow a starting Node, so it will scroll what I send it to scroll. Otherwise its assumptions to get the node from where to start scrolling from wont help Spatial Navigation. patch coming ... 226755 1 56241 tonikitoo 2010-05-17 07:18:31 -0700 Created attachment 56241 patch v1 226757 2 56242 tonikitoo 2010-05-17 07:22:28 -0700 Created attachment 56242 patch v2 And the right/newer/working version of the patch. 226811 3 tonikitoo 2010-05-17 10:39:27 -0700 (In reply to comment #2) > Created an attachment (id=56242) [details] > patch v2 Darin, could you please help me with this patch?
