Detailed Description
The QDragMoveEvent class provides an event which is sent while a drag and drop is in progress.
When a widget accepts drop
events, it will receive this event repeatedly while the
drag is within the widget's boundaries. The widget should examine
the event to see what data it provides, and accept() the drop if appropriate.
Note that this class inherits most of its functionality from
QDropEvent.

Member Function Documentation
QDragMoveEvent::QDragMoveEvent ( const QPoint & pos, Type type = DragMove )
Creates a QDragMoveEvent for which the mouse is at point pos,
and the event is of type type.
Warning: Do not create a QDragMoveEvent yourself since these
objects rely on Qt's internal state.
void QDragMoveEvent::accept ( const QRect & r )
The same as accept(), but also notifies that future moves will
also be acceptable if they remain within the rectangle r on the
widget: this can improve performance, but may also be ignored by
the underlying system.
If the rectangle is empty, then
drag move events will be sent continuously. This is useful if the
source is scrolling in a timer event.
QRect QDragMoveEvent::answerRect () const
Returns the rectangle for which the acceptance of the move event
applies.
void QDragMoveEvent::ignore ( const QRect & r )
The opposite of accept(const QRect&), i.e. says that moves within
rectangle r are not acceptable (will be ignored).
Example: dirview/dirview.cpp.
