from PyQt5.QtCore import Qt, QMimeData
from PyQt5.QtGui import QDrag

class Button(QPushButton):

            mimeData = QMimeData()
            drag = QDrag(self)
            drag.setMimeData(mimeData)

        self.setAcceptDrops(True)

        self.button = Button('My Button', self)
        self.button.move(50, 50)

    def dragEnterEvent(self, event):
        event.accept()

    def dropEvent(self, event):
        position = event.pos()
        self.button.move(position)
        event.accept()

    demo.show()
    sys.exit(app.exec_())
