webkit 通过键盘对 UI 控制

1，早期版本 的键盘控制可以通过以下API实现

   /webcore/khtml/Khtmlview.h

 

   class KHTMLView : public QScrollView

   KHTMLView::keyPressEvent

// Move to the next focusable node according to the direction indicated.
// 4 directions: DIR_LEFT, DIR_RIGHT, DIR_UP, DIR_DOWN
// There's no structure to hold node order in each direction. And we can't
// presume a pre-decidable order for every page.
// The algorithm compares all the node to get the closer one in the indicated
// direction basically.
bool KHTMLView::focusMoveToNode(Direction dir)

2，可以对其进行了封装

将khtmlview作为 KWQKHTMLPart 的一个成员，从而实现part对view的控制
