Detailed Description▲
A widget will receive drag move events repeatedly while the drag is within its boundaries, if it accepts drop events and enter events. The widget should examine the event to see what kind of https:// it provides, and call the https://() function to accept the drop if appropriate.
The rectangle supplied by the https://() function can be used to restrict drops to certain parts of the widget. For example, we can check whether the rectangle intersects with the geometry of a certain child widget and only call https://() if that is the case.
Note that this class inherits most of its functionality from https://.

Member Function Documentation▲
QDragMoveEvent::QDragMoveEvent(const QPoint &pos, Qt::DropActions actions, const QMimeData *data, Qt::MouseButtons buttons, Qt::KeyboardModifiers modifiers, QEvent::Type type = DragMove)▲
Creates a https:// of the required type indicating that the mouse is at position pos given within a widget.
The mouse and keyboard states are specified by buttons and modifiers, and the actions describe the types of drag and drop operation that are possible. The drag data is passed as MIME-encoded information in data.
Do not attempt to create a https:// yourself. These objects rely on Qt's internal state.
[virtual] QDragMoveEvent::~QDragMoveEvent()▲
Destroys the event.
void QDragMoveEvent::accept(const QRect &rectangle)▲
The same as https://(), but also notifies that future moves will also be acceptable if they remain within the rectangle given on the widget. This can improve performance, but may also be ignored by the underlying system.
If the rectangle is empty, drag move events will be sent continuously. This is useful if the source is scrolling in a timer event.
void QDragMoveEvent::accept()▲
This is an overloaded function.
Calls https://().
QRect QDragMoveEvent::answerRect() const▲
Returns the rectangle in the widget where the drop will occur if accepted. You can use this information to restrict drops to certain places on the widget.
void QDragMoveEvent::ignore(const QRect &rectangle)▲
The opposite of the accept(const https://&) function. Moves within the rectangle are not acceptable, and will be ignored.
void QDragMoveEvent::ignore()▲
This is an overloaded function.
Calls https://().
