Qt 3 Support Members for QDropEventОписанные ниже члены класса являются частью слоя поддержки Qt 3. Они введены для поддержки старого кода в Qt 4. Мы советуем не использовать их во вновь создаваемом коде. Открытые типы

Описание типов-членовenum QDropEvent::ActionWhen a drag and drop action is completed, the target is expected to perform an action on the data provided by the source. This will be one of the following:
The Link and Move actions only makes sense if the data is a reference, for example, text/uri-list file lists (see QUriDrag). Описание функций-членовvoid QDropEvent::accept ( bool accept )Call setAccepted(accept) instead. void QDropEvent::acceptAction ( bool accept = true )Call this to indicate that the action described by action() is accepted (i.e. if accept is true, which is the default), not merely the default copy action. If you call acceptAction(true), there is no need to also call accept(true). Action QDropEvent::action () constUse dropAction() instead. The table below shows the correspondance between the return type of action() and the return type of dropAction().
QByteArray QDropEvent::data ( const char * f ) constThe encoded data is in f. Use QDropEvent::encodedData(). QByteArray QDropEvent::encodedData ( const char * format ) const [virtual]Returns a byte array containing the drag's data, in format. data() normally needs to get the data from the drag source, which is potentially very slow, so it's advisable to call this function only if you're sure that you will need the data in that particular format. The resulting data will have a size of 0 if the format was not available. Reimplemented from QMimeSource. See also format() and QByteArray::size(). const char * QDropEvent::format ( int n = 0 ) const [virtual]Returns a string describing one of the available data types for this drag. Common examples are "text/plain" and "image/gif". If n is less than zero or greater than the number of available data types, format() returns 0. This function is provided mainly for debugging. Most drop targets will use provides(). Reimplemented from QMimeSource. See also data() and provides(). bool QDropEvent::provides ( const char * mimeType ) const [virtual]Returns true if this event provides format mimeType; otherwise returns false. Reimplemented from QMimeSource. Смотрите также data(). void QDropEvent::setPoint ( const QPoint & point )Sets the drop to happen at the given point. You do not normally need to use this as it will be set internally before your widget receives the drop event.
