Direct Known Subclasses:
  QDragEnterEvent

    public class QDragMoveEvent

extends QDropEvent

The QDragMoveEvent class provides an event which is sent while a drag and drop action is in progress. 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 data it provides, and call the `accept()` function to accept the drop if appropriate.

The rectangle supplied by the `answerRect()` 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 `acceptProposedAction()` if that is the case.

Note that this class inherits most of its functionality from `QDropEvent`.

  `QDragEnterEvent`, `QDragLeaveEvent`, and `QDropEvent`.

Constructor Summary
`QDragMoveEvent(QPoint pos, Qt.DropActions actions, QMimeData data, Qt.MouseButtons buttons, Qt.KeyboardModifiers modifiers)` Creates a QDragMoveEvent of the required `type` indicating that the mouse is at position `pos` given within a widget.

Method Summary
`void` | `accept(QRect r)` The same as `accept()`, but also notifies that future moves will also be acceptable if they remain within the `rectangle` given on the widget.
`QRect` | `answerRect()` Returns the rectangle in the widget where the drop will occur if accepted.
`void` | `ignore(QRect r)` The opposite of the accept(const `QRect`&) function.

Constructor Detail

### QDragMoveEvent

    public QDragMoveEvent(QPoint pos,
                          Qt.DropActions actions,
                          QMimeData data,
                          Qt.MouseButtons buttons,
                          Qt.KeyboardModifiers modifiers)

  Creates a QDragMoveEvent 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`.

  Warning: Do not attempt to create a QDragMoveEvent yourself. These objects rely on Qt's internal state.

### QDragMoveEvent

    public QDragMoveEvent(QPoint pos,
                          Qt.DropActions actions,
                          QMimeData data,
                          Qt.MouseButtons buttons,
                          Qt.KeyboardModifiers modifiers,
                          QEvent.Type type)

  Creates a QDragMoveEvent 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`.

  Warning: Do not attempt to create a QDragMoveEvent yourself. These objects rely on Qt's internal state.

Method Detail

### accept

    public final void accept(QRect r)

  The same as `accept()`, 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.

### answerRect

    public final QRect answerRect()

  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.

### ignore

    public final void ignore(QRect r)

  The opposite of the accept(const `QRect`&) function. Moves within the `rectangle` are not acceptable, and will be ignored.

### setRect

    protected final void setRect(QRect rect)

### rect

    protected final QRect rect()

### toString

    public java.lang.String toString()

  Returns a string representation of the `this QDragMoveEvent`.

  Overrides:
    `toString` in class `QDropEvent`
