Bug 45073 – Implement [continuous]MouseScrollBy() in Chromium/GTK DRT

• Component: WebKit Misc.
• Status: RESOLVED FIXED

[Peter Kasting]

http://trac.webkit.org/changeset/55739 added mouseScrollBy() and continuousMouseScrollBy() support for DRT on Mac, and it is now used in at least three layout tests.

http://trac.webkit.org/changeset/48735 added a very similar function called mouseWheelTo() to DRT on GTK and used it in one test.  "mouseWheelTo" is not a particularly great name as it implies a destination coordinate when in fact it merely takes a wheel tick value.  The actual functionality is identical except for having reversed signs (mouseScrollBy() matches the WebCore directionality for wheel events with positive and negative deltas; mouseWheelTo() is reversed).

Therefore, I intend to implement xxxMouseScrollBy() in Chromium in order to be able to pass the tests that use it, and remove mouseWheelTo() support since it's redundant.  I'll also change the GTK test to call mouseScrollBy() and modify the GTK DRT to convert mouseWheelTo() to mouseScrollBy().  (I'm not planning on implementing continuousMouseScrollBy() on GTK as more than a stub, since the GTK event layer doesn't seem to support continuous scroll events.)
