A QMouseDevice delegates mouse events from physical mouse device to QMouseHandler objects. The sensitivity of the mouse can be controlled with the QMouseDevice::sensitivity property, which specifies the rate in which the logical mouse coordinates change in response to physical movement of the mouse.

若
true
, axes will be updated anytime they change regardless of whether any mouse button is being pressed. Otherwise, axes are updated only when one of the mouse buttons is being pressed.
