           Summary: [gdk] Use a GtkLayout for the ScrollView implementation
                    to get real scrollbars
           Product: WebKit
           Version: 522+ (nightly)
          Platform: Macintosh
        OS/Version: Mac OS X 10.4
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: New Bugs
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: freyther at handhelds.org


Currently FrameGdk.cpp simulates scrolling by intercepting key events and
manipulating the RenderLayer. To have proper ScrollBars one needs to use
GtkAdjustment and probably be able to be included in a GtkScrolledWindow.

This patch removes the key event intercepting from FrameGdk, makes ScrollView
operate on a GtkLayout which can be embedded into a GtkScrolledWindow.

Issues that this patch doesn't solve yet:
  - The FrameGdk WheelEvent handling needs some checking, I suspect that this
is unreached code.
  - ScrollView currently doesn't implement the ScrollBar policy.
  - Resource usage must be checked (valgrind)
  - I need to make sure to not have mixed up width/height
