我们从Python开源项目中，提取了以下11个代码示例，用于说明如何使用PyQt5.QtCore.QMimeData()。
def mousePressEvent(self, event): hotSpot = event.pos() mimeData = QMimeData() mimeData.setText(self.text()) mimeData.setData('application/x-hotspot', '%d %d' % (hotSpot.x(), hotSpot.y())) pixmap = QPixmap(self.size()) self.render(pixmap) drag = QDrag(self) drag.setMimeData(mimeData) drag.setPixmap(pixmap) drag.setHotSpot(hotSpot) dropAction = drag.exec_(Qt.CopyAction | Qt.MoveAction, Qt.CopyAction) if dropAction == Qt.MoveAction: self.close() self.update()
def mouseMoveEvent(self, e): if e.buttons() != Qt.RightButton: return mimeData = QMimeData() drag = QDrag(self) drag.setMimeData(mimeData) drag.setHotSpot(e.pos() - self.rect().topLeft()) dropAction = drag.exec_(Qt.MoveAction)

def mimeData(self, indexes): """ This function is called by QT each time a drag operation is initiated, to serialize the data associated with the dragged item.
