QDropEvent::QDropEvent ( const QPoint & pos, Qt::DropActions actions, const QMimeData * data, Qt::MouseButtons buttons, Qt::KeyboardModifiers modifiers, Type type = Drop )

Constructs a drop event of a certain type corresponding to a drop at the point specified by pos in the destination widget's coordinate system.

The actions indicate which types of drag and drop operation can be performed, and the drag data is stored as MIME-encoded data in data.

The states of the mouse buttons and keyboard modifiers at the time of the drop are specified by buttons and modifiers.

void QDropEvent::acceptProposedAction ()

Sets the drop action to be the proposed action.

See also setDropAction(), proposedAction(), and accept().

Qt::DropAction QDropEvent::dropAction () const

Returns the action to be performed on the data by the target. This may be different from the action supplied in proposedAction() if you have called setDropAction() to explicitly choose a drop action.

See also setDropAction().

Qt::KeyboardModifiers QDropEvent::keyboardModifiers () const

Returns the modifier keys that are pressed.

const QMimeData * QDropEvent::mimeData () const

Returns the data that was dropped on the widget and its associated MIME type information.

Qt::MouseButtons QDropEvent::mouseButtons () const

Returns the mouse buttons that are pressed..

const QPoint & QDropEvent::pos () const

Returns the position where the drop was made.

Qt::DropActions QDropEvent::possibleActions () const

Returns an OR-combination of possible drop actions.

See also dropAction().

Qt::DropAction QDropEvent::proposedAction () const

Returns the proposed drop action.

See also dropAction().

void QDropEvent::setDropAction ( Qt::DropAction action )

Sets the action to be performed on the data by the target. Use this to override the proposed action with one of the possible actions.

If you set a drop action that is not one of the possible actions, the drag and drop operation will default to a copy operation.

Once you have supplied a replacement drop action, call accept() instead of acceptProposedAction().

See also dropAction().

QWidget * QDropEvent::source () const

If the source of the drag operation is a widget in this application, this function returns that source; otherwise it returns 0. The source of the operation is the first parameter to the QDrag object used instantiate the drag.

This is useful if your widget needs special behavior when dragging to itself.
