QDragMoveEvent(3qt)QDragMoveEvent(3qt)NAMEQDragMoveEvent - Event which is sent while a drag and drop is in
progress
SYNOPSIS
#include <qevent.h>
Inherits QDropEvent.
Inherited by QDragEnterEvent.
Public Members
QDragMoveEvent ( const QPoint & pos, Type type = DragMove )
QRect answerRect () const
void accept ( const QRect & r )
void ignore ( const QRect & r )
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.
See also Drag And Drop Classes and Event Classes.
MEMBER FUNCTION DOCUMENTATIONQDragMoveEvent::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.
Examples:
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.
