[pattin.shieh]

I am making a brower,by using webkit.I want make the browser support like
following description:
    1).User click a editor;
    2).Page zoom to 150% and auto scroll the view,let the eidtor(node) in
the center of the view;
    4)Pop up the input window;
    5).user easily enter text.

I wondering where to add the code, can somebody tell me?
Is it the best way or right? If let the webview catch the click-message and
then m_frame->setZoomFactor and frame->view()->scroll ? And ,how to catch
the click message?
