* 'master' of git://scm.dev.nokia.troll.no/qt/qt-releng-team: (195 commits) Re-apply licenseheader text in source files for qt4.8 Revert all QScroller and QFlickGesture related code. Fix regression that caused waitForXXX(-1) to fail. Fix thread safety regression of QNetworkConfigurationManager Fix instability in QNetworkConfigurationManager autotest Support word selection list with predictive text from splitview Fix softkey icon positioning in S60 5.3 QDeclarativeMouseArea: block context menu events ListViews loses items if all visible items are removed. Make TextEdit word selection more natural. Fixed license header. Ensure that recursive QMAKE_EXTRA_TARGETS use the correct makefile Clear confusion between QMainWindow and QMainWindowLayout. Fix for rounded corners bug in QMenu Compile QWidgetPrivate::setParent_sys might be using null pointer Ensure the TextEdit cursor delegate is repositioned on mouse events. Don't crash on an invalid replacementStart from an input method. Fix QGLWidget::renderPixmap for raster engine on Mac Check if OES_texture_npot is present on OpenGL ES 2. ...

+// This is the implementation of the unified toolbar on Mac OS X

+//
+// General idea:
+// -------------
+// We redirect the painting of widgets inside the unified toolbar
+// to a special window surface, the QUnifiedToolbarSurface.
+// We need a separate window surface because the unified toolbar
+// is out of the content view.
+// The input system is the same as for the unified toolbar with the
+// native (CoreGraphics) engine.
+//
+// Execution flow:
+// ---------------
+// The unified toolbar is triggered by QMainWindow::setUnifiedTitleAndToolBarOnMac().
+// It calls QMainWindowLayout::insertIntoMacToolbar() which will
+// set all the appropriate variables (offsets, redirection, ...).
+// When Qt tells a widget to repaint, QWidgetPrivate::drawWidget()
+// checks if the widget is inside the unified toolbar and exits without
+// painting is that is the case.
+// We trigger the rendering of the unified toolbar in QWidget::repaint()
+// and QWidget::update().
+// We keep track of flush requests via "flushRequested" variable. That
+// allow flush() to be a no-op if no repaint occurred for a widget.
+// We rely on the needsDisplay: and drawRect: mecanism for drawing our
+// content into the graphics context.
+//
+// Notes:
+// ------
+// The painting of items inside the unified toolbar is expensive.
+// Too many repaints will drastically slow down the whole application.

-    The QFlickGesture is more complex than the QPanGesture that uses QScroller and QScrollerProperties
-    to decide if it is triggered.
-    This gesture is reacting on touch event as compared to the QMouseFlickGesture.

-/*!
-    \class QScroller
-    \brief The QScroller class enables kinetic scrolling for any scrolling widget or graphics item.
-    \since 4.8
-
-    With kinetic scrolling, the user can push the widget in a given
-    direction and it will continue to scroll in this direction until it is
-    stopped either by the user or by friction.  Aspects of inertia, friction
-    and other physical concepts can be changed in order to fine-tune an
-    intuitive user experience.
-
-    The QScroller object is the object that stores the current position and
-    scrolling speed and takes care of updates.
-    QScroller can be triggered by a flick gesture
-
-    \code
-        QWidget *w = ...;
-        QScroller::grabGesture(w, QScroller::LeftMouseButtonGesture);
-    \endcode
-
-    or directly like this:
-
-    \code
-        QWidget *w = ...;
-        QScroller *scroller = QScroller::scroller(w);
-        scroller->scrollTo(QPointF(100, 100));
-    \endcode
-
-    The scrolled QObjects receive a QScrollPrepareEvent whenever the scroller needs to
-    update its geometry information and a QScrollEvent whenever the content of the object should
-    actually be scrolled.
-
-    The scroller uses the global QAbstractAnimation timer to generate its QScrollEvents. This
-    can be changed with QScrollerProperties::FrameRate on a per-QScroller basis.
-
-    Several examples in the \c scroller examples directory show how QScroller,
-    QScrollEvent and the scroller gesture can be used.
-
-    Even though this kinetic scroller has a large number of settings available via
-    QScrollerProperties, we recommend that you leave them all at their default, platform optimized
-    values. Before changing them you can experiment with the \c plot example in
-    the \c scroller examples directory.

-*/
-
-/*!
-    \enum QScrollerProperties::ScrollMetric
-
-    This enum contains the different scroll metric types. When not indicated otherwise the
-    setScrollMetric function expects a QVariant of type qreal.
-
-    See the QScroller documentation for further details of the concepts behind the different
-    values.
-
-    \value MousePressEventDelay This is the time a mouse press event is delayed when starting
-    a flick gesture in \c{[s]}. If the gesture is triggered within that time, no mouse press or
-    release is sent to the scrolled object. If it triggers after that delay the delayed
-    mouse press plus a faked release event at global postion \c{QPoint(-QWIDGETSIZE_MAX,
-    -QWIDGETSIZE_MAX)} is sent. If the gesture is canceled, then both the delayed mouse
-    press plus the real release event are delivered.
-
-    \value DragStartDistance This is the minimum distance the touch or mouse point needs to be
-    moved before the flick gesture is triggered in \c m.
-
-    \value DragVelocitySmoothingFactor A value that describes to which extent new drag velocities are
-    included in the final scrolling velocity.  This value should be in the range between \c 0 and
-    \c 1.  The lower the value, the more smoothing is applied to the dragging velocity.
-
-    \value AxisLockThreshold Restricts the movement to one axis if the movement is inside an angle
-    around the axis. The threshold must be in the range \c 0 to \c 1.
-
-    \value ScrollingCurve The QEasingCurve used when decelerating the scrolling velocity after an
-    user initiated flick. Please note that this is the easing curve for the positions, \bold{not}
-    the velocity: the default is QEasingCurve::OutQuad, which results in a linear decrease in
-    velocity (1st derivative) and a constant deceleration (2nd derivative).
-
-    \value DecelerationFactor This factor influences how long it takes the scroller to decelerate
-    to 0 velocity. The actual value depends on the chosen ScrollingCurve. For most
-    types the value should be in the range from \c 0.1 to \c 2.0
-
-    \value MinimumVelocity The minimum velocity that is needed after ending the touch or releasing
-    the mouse to start scrolling in \c{m/s}.
-
-    \value MaximumVelocity This is the maximum velocity that can be reached in \c{m/s}.
-
-    \value MaximumClickThroughVelocity This is the maximum allowed scroll speed for a click-through
-    in \c{m/s}. This means that a click on a currently (slowly) scrolling object will not only stop
-    the scrolling but the click event will also be delivered to the UI control. This is
-    useful when using exponential-type scrolling curves.
-
-    \value AcceleratingFlickMaximumTime This is the maximum time in \c seconds that a flick gesture
-    can take to be recognized as an accelerating flick. If set to zero no such gesture is
-    detected. An "accelerating flick" is a flick gesture executed on an already scrolling object.
-    In such cases the scrolling speed is multiplied by AcceleratingFlickSpeedupFactor in order to
-    accelerate it.
-
-    \value AcceleratingFlickSpeedupFactor The current speed is multiplied by this number if an
-    accelerating flick is detected. Should be \c{>= 1}.
-
-    \value SnapPositionRatio This is the distance that the user must drag the area beween two snap
-    points in order to snap it to the next position. \c{0.33} means that the scroll must only
-    reach one third of the distance between two snap points to snap to the next one. The ratio must
-    be between \c 0 and \c 1.
-
-    \value SnapTime This is the time factor for the scrolling curve. A lower value means that the
-    scrolling will take longer. The scrolling distance is independet of this value.
-
-    \value OvershootDragResistanceFactor This value is the factor between the mouse dragging and
-    the actual scroll area movement (during overshoot). The factor must be between \c 0 and \c 1.
-
-    \value OvershootDragDistanceFactor This is the maximum distance for overshoot movements while
-    dragging. The actual overshoot distance is calculated by multiplying this value with the
-    viewport size of the scrolled object. The factor must be between \c 0 and \c 1.
-
-    \value OvershootScrollDistanceFactor This is the maximum distance for overshoot movements while
-    scrolling. The actual overshoot distance is calculated by multiplying this value with the
-    viewport size of the scrolled object. The factor must be between \c 0 and \c 1.
-
-    \value OvershootScrollTime This is the time in \c seconds that is used to play the
-    complete overshoot animation.
-
-    \value HorizontalOvershootPolicy This is the horizontal overshooting policy (see OvershootPolicy).
-
-    \value VerticalOvershootPolicy This is the horizontal overshooting policy (see OvershootPolicy).
-
-    \value FrameRate This is the frame rate which should be used while dragging or scrolling.
-    QScroller uses a QAbstractAnimation timer internally to sync all scrolling operations to other
-    animations that might be active at the same time.  If the standard value of 60 frames per
-    second is too fast, it can be lowered with this setting,
-    while still being in-sync with QAbstractAnimation. Please note that only the values of the
-    FrameRates enum are allowed here.
-
-    \value ScrollMetricCount This is always the last entry.
