Returns true
if the given point (as part of event) could be relevant at all to this handler, as a preliminary check.
If you override this function, you should call the immediate parent class implementation (and return false
if it returns false
); that in turn calls its parent class implementation, and so on.
In particular, the bounds checking is done here: the base class QQuickPointerHandler::wantsEventPoint() calls parentContains(point) (which allows the flexibility promised by margin(), QQuickItem::contains() and QQuickItem::containmentMask()). Pointer Handlers can receive QEventPoints that are outside the parent item's bounds: this allows some flexibility for dealing with multi-point gestures in which one or more fingers have strayed outside the bounds, and yet the gesture is still unambiguously intended for the target() item.
You should not generally react to the event or point here, but it's ok to set state to remember what needs to be done in your overridden handlePointerEventImpl() or QQuickSinglePointHandler::handleEventPoint().
Reimplemented from QQuickPointerHandler.
