How to display image from current working directory in Python
Question: I would like to display an image using multiple label in a GUI(Qt Designer).
The image file should be grab from current working directory and display on it
own label upon user press Push Button.

Image can be displayed in label_2 when i hardcoded the image directory path
but not for label_1.

    
    
      def capture_image(self):
    
        cam = cv2.VideoCapture(0)
    
        print('Execute_captureImage')
    
        i = 1
        while i <= int(self.qty_selected):
            # while i < 2:
            ret, frame = cam.read()
            cv2.imshow('Please review image before capture', frame)
    
            if not ret:
                break
            k = cv2.waitKey(1)
    
            if k % 256 == 27:
                # ESC pressed
                print("Escape hit, closing...")
                break
            if k % 256 == 32:
                # SPACE pressed
                self.img_name = self.lotId + '_{}.jpeg'.format(i)
                path = 'c:\\Users\\Desktop\\Python\\Testing' + '\\' + self.lotId + '\\' + self.img_name
                print('CurrentImage = ' + path)
    
                if not os.path.exists(path):
                    print('Not yet exist')
                    cv2.imwrite(
                        os.path.join('c:\\Users\\Desktop\\Python\\Testing' + '\\' + self.lotId,
                                     self.img_name),
                        frame)
                    print("{}".format(self.img_name))
                    # i += 1
                    break
    
                else:
                    print('Image already exist')
                    i += 1
    
        cam.release()
        cv2.destroyAllWindows()
    
    
    
      def display_image(self):
    
           label_vid01 = 'c:\\Users\\Desktop\\Python\\Testing' + '\\' + self.lotId + '\\' + self.img_name
           label_vid02 = 'c:\\Users\\Desktop\\Python\\Testing' + '\\' + self.lotId + '\\' + self.img_name
           # label_vid03 = 'c:/Users/Desktop/Python/Image/image3.jpg'
           self.label_vid01.setScaledContents(True)
           self.label_vid02.setScaledContents(True)
           self.label_vid03.setScaledContents(True)
           self.label_vid01.setPixmap(QtGui.QPixmap(label_vid01))
           self.label_vid02.setPixmap(QtGui.QPixmap(label_vid02))
           print(repr(label_vid01))
           print(os.path.exists(label_vid01))
    

May i know where is the mistake?

'self.lotId' is input text based on user input.

Answer: The demo script below works for me on Windows XP. If this also works for you,
the problem must be in the `capture_image` function in your example (which I
cannot test at the moment).

    
    
    import sys, os
    from PyQt4 import QtCore, QtGui
    
    class Window(QtGui.QWidget):
        def __init__(self):
            super(Window, self).__init__()
            layout = QtGui.QVBoxLayout(self)
            self.viewer = QtGui.QListWidget(self)
            self.viewer.setViewMode(QtGui.QListView.IconMode)
            self.viewer.setIconSize(QtCore.QSize(256, 256))
            self.viewer.setResizeMode(QtGui.QListView.Adjust)
            self.viewer.setSpacing(10)
            self.button = QtGui.QPushButton('Test', self)
            self.button.clicked.connect(self.handleButton)
            self.edit = QtGui.QLineEdit(self)
            layout.addWidget(self.viewer)
            layout.addWidget(self.edit)
            layout.addWidget(self.button)
    
        def handleButton(self):
            self.viewer.clear()
            name = self.edit.text()
            for index in range(3):
                pixmap = QtGui.QPixmap()
                path = r'E:\Python\Testing\%s\%s_%d.jpg' % (name, name, index + 1)
                print('load (%s) %r' % (pixmap.load(path), path))
                item = QtGui.QListWidgetItem(os.path.basename(path))
                item.setIcon(QtGui.QIcon(path))
                self.viewer.addItem(item)
    
    if __name__ == '__main__':
    
        app = QtGui.QApplication(sys.argv)
        window = Window()
        window.setGeometry(800, 150, 650, 500)
        window.show()
        sys.exit(app.exec_())
