I wish this helpful for you When you create a QScrollArea with Qt Designer a widget called scrollAreaWidgetContents is created and this is the one inside the QScrollArea and therefore its size is used to establish what is shown in the scrollbar, in your case imageLabel is the son of scrollAreaWidgetContents it is observed but scrollAreaWidgetContents does not know the size of imageLabel, so in these cases you must use the layouts so that the minimum size of the scrollAreaWidgetContents matches that of the imageLabel.
import sys
from PyQt5 import QtCore, QtGui, QtWidgets, uic

class photo(QtWidgets.QDialog):
    def __init__(self,parent=None):
        super(photo, self).__init__(parent)
        uic.loadUi('EmployeeUpdate.ui', self)

    def attachImage(self):
        lay = QtWidgets.QVBoxLayout(self.scrollAreaWidgetContents)
        lay.setContentsMargins(0, 0, 0, 0)
        path = "G:/Data Analytics/Resnsol Face Recognition/a.jpg"
        pixMap = QtGui.QPixmap(path)
        self.imageLabel.setAlignment(QtCore.Qt.AlignHCenter | QtCore.Qt.AlignVCenter)

def main():
    app = QtWidgets.QApplication(sys.argv)
    window = photo()

pyqt5 trying to use QGridLayout to organise my QLabel, QLineEdit, QPushButton, and "Pop-up" QLabel

Tag : python-3.x , By : Dominique Vocat

it fixes the issue You call the createGridLayout method earlier than you define the variables used in it.
import sys
from PyQt5.QtWidgets import (QApplication, QWidget, QHBoxLayout, 
                            QVBoxLayout, QPushButton, QLabel, QLineEdit, 
                            QGridLayout, QGroupBox, QDialog)
from PyQt5.QtCore import pyqtSlot

class Window(QWidget):

    def __init__(self):


    def initUI(self):

        self.setWindowTitle("Project PiBu!!")

#        self.createGridLayout()
#        self.windowLayout = QVBoxLayout()
#        self.windowLayout.addWidget(self.horizontalGroupBox)
#        self.setLayout(self.windowLayout)

        self.game_name      = QLabel("Game Name:", self)
        self.game_line_edit = QLineEdit(self)
        self.search_button  = QPushButton("Search", self)
        self.game = QLabel(self)

        self.createGridLayout()                                 # < --
        self.windowLayout = QVBoxLayout()                       # < --
        self.windowLayout.addWidget(self.horizontalGroupBox)    # < --
        self.setLayout(self.windowLayout)                       # < --


    def createGridLayout(self):
        self.horizontalGroupBox = QGroupBox()
        self.layout = QGridLayout()
        self.layout.setColumnStretch(1, 4)
        self.layout.setColumnStretch(2, 4)

        # AttributeError: 'Window' object has no attribute 'game_name'
        self.layout.addWidget(self.game_name, 0, 0)

        self.layout.addWidget(self.game_line_edit, 0, 1)
        self.layout.addWidget(self.search_button, 0, 2)
        self.layout.addWidget(self.game, 1, 0)

        self.horizontalGroupBox.setLayout(self.layout)          # +++ self.

Draw over image in a QLabel with PyQt5

Tag : python , By : Tim

around this issue Do not draw inside a widget outside of the paintEvent(). This is not supported by Qt.
You may draw on a QImage or QPixmap instead, and then in paintEvent() of your widget, draw that image. Images can be initialized with all pixels transparent as well, if you like to composite several images (background+drawing) instead of drawing on the background directly.

PyQt5 Displaying an Image using a QLabel from Memory

Tag : python , By : janik
Date : March 29 2020, 07:55 AM
fixed the issue. Will look into that further You can load the image from memory using loadFromData
In your example, the following should work:
    img_data = load_operation_that_might_fail()
    myLabel.setText("no image available")

pixmap = QPixmap()
myLabel.loadFromData(img_data, 'png')
from PyQt5.QtWidgets import (QWidget, QHBoxLayout, QLabel, QApplication)
from PyQt5.QtGui import QPixmap
import sys

class Example(QWidget):

    def __init__(self):


    def initUI(self):
        hbox = QHBoxLayout(self)
        pixmap = QPixmap()
        pixmap.loadFromData(self.load_operation_that_might_fail(), 'png')

        lbl = QLabel(self)



    def load_operation_that_might_fail(self):
        with open('c:/temp/test.png', 'rb') as f:
            return f.read()

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

will help you I am trying to create a PyQt5 - QLabel with both image and text. I would like to have a text at the bottom of the image. Below is a part of the code , You have to use 2 QLabel in a QVBoxLayout:
import sys

from PyQt5.QtCore import Qt
from PyQt5.QtGui import QPixmap
from PyQt5.QtWidgets import QApplication, QLabel, QVBoxLayout, QWidget

class Window(QWidget):
    def __init__(self, parent=None):
        super(Window, self).__init__(parent)

        pixmap_label = QLabel(
        text_label = QLabel(text="delete")

        lay = QVBoxLayout(self)
        lay.addWidget(pixmap_label, alignment=Qt.AlignCenter)
        lay.addWidget(text_label, alignment=Qt.AlignCenter)

if __name__ == "__main__":

    app = QApplication(sys.argv)
    win = Window()

How do I align centre image on QLabel in PyQt5?

Tag : python , By : user160048
Date : March 29 2020, 07:55 AM
this will help The QPixmap is centered on the QLabel, but the problem is that the QLabel is not centered with respect to the window. So you should center the widget by changing to:
layout.addWidget(label_img, alignment=Qt.AlignCenter)
