How to display image on the GUI panel created with QGraphicsView using pyqtgraph

[aishwarya selvaraj]

Dear all, 
I have just started to work with PyQt and pyqtgraph.
I have managed to design a GUI for my requirement using Qt designer. I have defined a region on my layout where I want my images to be displayed.

from PyQt5 import QtCore, QtGui, QtWidgets

import pyqtgraph as pg
import random
class Ui_MainWindow(object):

     def setupUi(self, MainWindow):

        MainWindow.setObjectName("MainWindow")

        MainWindow.resize(926, 859)

        self.centralwidget = QtWidgets.QWidget(MainWindow)

        self.centralwidget.setObjectName("centralwidget")

        self.Display = QtWidgets.QGraphicsView(self.centralwidget)

        self.Display.setGeometry(QtCore.QRect(30, 130, 461, 541))

        font = QtGui.QFont()

        font.setPointSize(10)

        font.setBold(True)

        font.setWeight(75)

        self.Display.setFont(font)

        self.Display.setMouseTracking(True)

        self.Display.setAutoFillBackground(False)

        self.Display.setFrameShadow(QtWidgets.QFrame.Sunken)

        self.Display.setObjectName("Display")

    def Plot(self):
        // Upon A button click this functionis activated and the image has to be displayed//
        img = np.random.normal(size=(512,512))

        //How to place this images in the region defined??

As mentioned, how do I display the image "img" in the QGraphicsView. 
Can anyone please help me.

Hi,

If you are making the GUI layout in Qt Designer, you want to "promote" your QGraphicsView to a pyqtplot GraphicsView, following these instructions:

http://www.pyqtgraph.org/documentation/how_to_use.html#embedding-widgets-inside-pyqt-applications

Once you have a pyqtgraph GraphicsView, make an ImageItem and place it inside your GraphicsView. Then self.imageitem.setImage(img) should do it. Check one of the ImageItem examples.
