I want to get and show images with Drag&Drop metho

I want to get and show images with Drag&Drop methods of pyqt5. For example,like this image,

I want to make Drag&Drop space and Image-show space.

import sys
from PyQt5.QtWidgets import (QPushButton, QWidget,
    QLineEdit, QApplication)
from PyQt5.QtCore import *
from PyQt5.QtGui import *
from PyQt5.QtWidgets import *



class Button(QPushButton):

    def __init__(self, title, parent):
        super().__init__(title, parent)

        self.setAcceptDrops(True)


    def dragEnterEvent(self, e):

        if e.mimeData().hasFormat('image/*'):
            e.accept()
        else:
            e.ignore()

    def dropEvent(self, e):
        self.label.setPixmap(QPixmap(event.mimeData().imageData())) 


class Example(QWidget):

    def __init__(self):
        super().__init__()

        self.initUI()


    def initUI(self):

        button = Button("",self)
        button.resize(100,100) 
        button.setIcon(QIcon("gazo1.jpg")) 
        button.setIconSize(QSize(100,100))
        button.move(0, 0)

        self.label = QLabel(self)
        self.label.setPixmap(QPixmap('gazo2.jpg'))
        self.label.move(150,150)

        self.setWindowTitle('Simple drag & drop')
        self.setGeometry(300, 300, 300, 300)


if __name__ == '__main__':

    app = QApplication(sys.argv)
    ex = Example()
    ex.show()
    app.exec_()

I expect that if I drag&drop jpg-image in upper left space, the image is showed in the middle space. But when I drag jpg image to the upper left space, "drop enabled mark" isn't displayed. So when I drag&drop a image, there is no reaction.

As you want to drag an image from the desktop, the path of this image provides it through a local url, to verify it uses the mimeData(). hasUrls(), and urls() to get the url, then we get the local path with the method toLocalFile(), all the above is implemented in the following code:

class Button(QPushButton):
    def __init__(self, title, parent):
        super().__init__(title, parent)
        self.setAcceptDrops(True)

    def dragEnterEvent(self, e):
        m = e.mimeData()
        if m.hasUrls():
            e.accept()
        else:
            e.ignore()

    def dropEvent(self, e):
        m = e.mimeData()
        if m.hasUrls():
            self.parent().label.setPixmap(QPixmap(m.urls()[0].toLocalFile())) 


class Example(QWidget):
    def __init__(self):
        super().__init__()
        self.initUI()

    def initUI(self):
        button = Button("",self)
        button.resize(100,100) 
        button.setIcon(QIcon("gazo1.jpg")) 
        button.setIconSize(QSize(100,100))
        button.move(0, 0)

        self.label = QLabel(self)
        self.label.setPixmap(QPixmap('gazo2.png'))
        self.label.move(150,150)

        self.setWindowTitle('Simple drag & drop')
        self.setGeometry(300, 300, 300, 300)


if __name__ == '__main__':
    app = QApplication(sys.argv)
    ex = Example()
    ex.show()
    app.exec_()
