TheQPlatformCursor class provides information about pointer device events (movement, buttons), and requests to change the currently displayed cursor.
Note thatQPlatformCursor does not include any graphics for display. An application that sets aQCursor may provide its own graphics.

Constructs aQPlatformCursor for the givenscreen.
[pure virtual]void QPlatformCursor::changeCursor(QCursor * widgetCursor,QWidget * widget)This method is called by Qt whenever the cursor graphic should be changed.
Implementation of this method is mandatory for a subclass ofQPlatformCursor.
widgetCursor is a pointer to theQCursor that should be displayed.
widget is a pointer to the widget currently displayed atQCursor::pos(). Note that this may be 0 if the current position is not occupied by a displayed widget.
See alsoQCursor::pos().
[virtual]void QPlatformCursor::pointerEvent(constQMouseEvent & event)This method is called by Qt whenever aQMouseEvent is generated by the underlying pointer input.event is a reference to theQMouseEvent in question. A default do-nothing implementation is provided.
[virtual]QPoint QPlatformCursor::pos() constSee alsosetPos().
[virtual]void QPlatformCursor::setPos(constQPoint & pos)See alsopos().
