DESCRIPTION
Event sent as a drag-and-drop is in progress.
When a widget accepts drop events, it will receive this
event repeatedly while the the drag is inside that widget.
The widget should examine the event, especially seeing
what data it provides, and accept() the drop if
appropriate.
Note that this class inherits most of its functionality
from QDropEvent.
Examples: desktop/desktop.cpp
MEMBER FUNCTION DOCUMENTATIONQDragMoveEvent::QDragMoveEvent ( const QPoint & pos, Type
type=DragMove )
Creates a QDragMoveEvent for which the mouse is at point
pos, and the given event type.
Note that internal state is also involved with
QDragMoveEvent, so it is not useful to create these
yourself.
void QDragMoveEvent::accept ( bool y=TRUE )
Reimplemented for internal reasons; the API is not
affected.
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.

QDragMoveEvent(3qt)QDragMoveEvent(3qt)QRect QDragMoveEvent::answerRect () const

void QDragMoveEvent::ignore ()
Reimplemented for internal reasons; the API is not
affected.
void QDragMoveEvent::ignore ( const QRect & r )
The opposite of accept(const QRect&).
