           Summary: [Qt] QtTestBrowser: lazy instantiate "YRotation" state
                    machine and related objects
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: PC
        OS/Version: All
            Status: NEW
          Keywords: Qt, QtTriaged
          Severity: Normal
          Priority: P2
         Component: Tools / Tests
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: tonikitoo at webkit.org


As is, we are creating the QStateMachine and all associated objects (QState, QPropertyAnimations and QAbstractTransition) for the YRotation action (Developer->GraphicsView->YRotation) at WebViewGraphicsBased constructor time. It is unnecessery.

Patch moves all this stuff to the slot that is activated by the associated menuitem to this action, lazily initiating it.
