Pretty stupid comment :-) pls remove and add Added

we normally use the name "it" in webkit

why not (*it)->set...

> Tools/MiniBrowser/qt/MiniBrowserApplication.cpp:174

+ . at the end :-)

> Tools/MiniBrowser/qt/qml/TouchMockPoint.qml:31

isn't that default?

updateMockTouchPoints

Look up old touch points that you can re-use from the engine based on the id, instead of keeping a list.

> Tools/MiniBrowser/qt/BrowserWindow.cpp:97
> +    iter.value()->setX(position.x() / 2);

set the x and y, and do the offsetting to center it in the qml

i'd rather see a "pressed" property that you set and unset based on the point being released or not, and you can then deal with how you hide it in the qml

> Tools/MiniBrowser/qt/MiniBrowserApplication.cpp:163

do we ever have a situation without a browser window?

> Tools/MiniBrowser/qt/MiniBrowserApplication.cpp:168
> +        qreal opacity = 1.0;

see comment about "pressed". we should not deal with opacity here, that's an implementation detail of the visual component

Or, updateVisualMockTouchPoints

Set the objectName instead of the id, and use rootObject()->findChild<QQuickItem*>(mockTouchPointIdentifier);

> Tools/MiniBrowser/qt/BrowserWindow.cpp:118

replace the pressed variable with touchPoint.state == Qt::TouchPointReleased

if (BrowserWindow* browserWindow = qobject_cast<BrowserWindow*>(targetWindow))
    browserWindow->updateVisualMockTouchPoints(m_touchPoints.values());

Move this down to where you set it, and remove the pressed-variable, you can set the property directly based on touchPoint.state != Qt::TouchPointReleased
