           Summary: Text controls only emit the start editing signal after
                    the first keypress
           Product: WebKit
           Version: 526+ (Nightly build)
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: Forms
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: iain at openedhand.com

I'm writing a backend for Clutter and I was hooking up an onscreen keyboard to
WebKit so that it would area when the user selected a text control. I was using
EditorClient::textFieldDidBeginEditing() to control when the keyboard appeared,
but this method is only called once the user has entered something in the text
area. There we get a chicken/egg problem, the keyboard can't appear until the
user types something, but the user cant type something without the keyboard.

Attached is a patch that moves the place where
EditorClient::textFieldDidBeginEditing() gets called from
RenderTextControl::subtreeHasChanged() to
HTMLTextFieldInnerTextElement::defaultEventHandler() although I don't know if
this is the best way? Would it be preferable that there is an
EditorClient::textFieldMaybeBeginEditing method as well as
textFieldDidBeginEditing which would get called when the control gets focused
and textFieldDidBeginEditing would be still called where it is now?

Or am I completely barking up the wrong tree here and completely missed
