I'm trying to display a PNG image in a Widget using QLabel. I built the Widget using Qt Designer and the label shows the image properly. When I load the .ui into mi .py and execute it, everything shows up well, except for the label. I tried loading the QPixmap manually on the python code, but it didn't work either.
from PyQt5.QtWidgets import (QApplication, QLabel)
from PyQt5.QtGui import (QPixmap)
from PyQt5 import uic
import sys
import os
form = uic.loadUiType('gui/Files/Login.ui')
class LoginWindow(form[0], form[1]):
def __init__(self):
super().__init__()
self.setupUi(self)
self.logoLabel.setPixmap(QPixmap(os.path.abspath(os.path.join(os.path.dirname(__file__), 'logo.png'))))
self.logoLabel.show()
if __name__ == '__main__':
app = QApplication(sys.argv)
win = LoginWindow()
win.show()
app.exec_()
Any idea what am I doing wrong? Any sugestions on how could I display the image other than with QLabel?

loadUi('GUI.ui',self)
self.image=None
self.loadButton.clicked.connect(self.loadClicked)
#pyqtSlot()
def loadClicked(self):
self.loadImage('smarthealth.jpg')
def loadImage(self,img="smarthealth.jpg"):
self.image=cv2.imread(img)
self.displayImage()
def displayImage(self):
qformat=QImage.Format_Indexed8
if len(self.image.shape)== 3:
if (self.image.shape[2])== 4:
qformat=QImage.Format_RGBA8888
else:
qformat=QImage.Format_RGB888
img=QImage(self.image,self.image.shape[1],self.image.shape[0],
self.image.strides[0],qformat)
img = img.rgbSwapped()
self.imgLabel.setAlignment(QtCore.Qt.AlignHCenter|QtCore.Qt
.AlignVCenter)
app=QtWidgets.QApplication(sys.argv)
window= ShowImage()
window.setWindowTitle('Show Image GUI')
window.show()
sys.exit(app.exec())
I have created a piece of code that show a simple webpage (a bokeh graph saved in an html file). This code is working in Windows 10 at work, but on macos-mojave, using PyQT5.9, with Python 3.6, the opened window don't show anything, and makes python crash.
Could anyone helps ?
Many thanks

I'm still new with python and Qt designer. I would like to develop an application where user need to press the 'pushbutton' in order to view the image(from local directory path) on GUI mainwindow.This will keep repeating until complete number of cycle.
Did tried using QLabel and QGraphiscView widget but doesn't work.(probably due to lack of knowledge). Could anyone help me to solve it?
Below is the code:
#!/usr/bin/env python
from __future__ import division
import sys
from PyQt4 import QtCore, QtGui, uic
gui_file = 'image.ui'
Ui_MainWindow, QtBaseClass = uic.loadUiType(gui_file)
class showImage(QtGui.QMainWindow,Ui_MainWindow):
def __init__(self):
QtGui.QMainWindow.__init__(self)
Ui_MainWindow.__init__(self)
self.setupUi(self)
self.get_image_button.clicked.connect(self.getImage)
def getImage(self):
image_path='c:/Users/mohd_faizal4/Desktop/Python/Image/image1.jpg' #path to image file
self.label_image.QPixmap(image_path)
if __name__ == '__main__':
app = QtGui.QApplication(sys.argv)
myWindow = showImage()
myWindow.show()
sys.exit()
app.exec_()
Really appreciate!
I've been learning python recently and now I wanted to (try to) create my first real application, a subtitle player for Linux. So far I've been using the Greenfish subtitle player, which is aimed at Windows users and not properly working in Linux.
I wanted to create the application in qt, since I discovered that transparent windows are not possible in tkinter, but if anybody knows a better framework please suggest!
Now before starting I've been researching the web for several hours to discover how to get my application to show over a full screened flash video and it seems like this is not possible. However the aforementioned GF subtitle player manages to do so in Windows, but not in Linux(maybe it's also because it's running through wine).
So my question is it possible to create a transparent application that remains over a fullscreened flash video and if so, could you point me in the right direction?
Thanks in advance.
edit:
here some example code I've been trying. The window produced by this piece of code does not stay above a fullscreened video
import sys
from PyQt4 import QtGui, QtCore
class mymainwindow(QtGui.QMainWindow):
def __init__(self):
QtGui.QMainWindow.__init__(self, None, QtCore.Qt.WindowStaysOnTopHint)
app = QtGui.QApplication(sys.argv)
mywindow = mymainwindow()
mywindow.show()
app.exec_()
mywindow.show()
Update for PyQt5 pip install PyQt5
import sys
from PyQt5 import QtGui, QtCore, uic
from PyQt5 import QtWidgets
from PyQt5.QtWidgets import QMainWindow, QApplication
class MainWindow(QMainWindow):
def __init__(self):
QMainWindow.__init__(self)
self.setWindowFlags(
QtCore.Qt.WindowStaysOnTopHint |
QtCore.Qt.FramelessWindowHint |
QtCore.Qt.X11BypassWindowManagerHint
)
self.setGeometry(
QtWidgets.QStyle.alignedRect(
QtCore.Qt.LeftToRight, QtCore.Qt.AlignCenter,
QtCore.QSize(220, 32),
QtWidgets.qApp.desktop().availableGeometry()
))
def mousePressEvent(self, event):
QtWidgets.qApp.quit()
if __name__ == '__main__':
app = QApplication(sys.argv)
mywindow = MainWindow()
mywindow.show()
app.exec_()
The example code below will create a centred, frameless window that should stay on top of all other windows on Linux (you can click on the window to close it).
import sys
from PyQt4 import QtGui, QtCore
class mymainwindow(QtGui.QMainWindow):
def __init__(self):
QtGui.QMainWindow.__init__(self)
self.setWindowFlags(
QtCore.Qt.WindowStaysOnTopHint |
QtCore.Qt.FramelessWindowHint |
QtCore.Qt.X11BypassWindowManagerHint
)
self.setGeometry(QtGui.QStyle.alignedRect(
QtCore.Qt.LeftToRight, QtCore.Qt.AlignCenter,
QtCore.QSize(220, 32),
QtGui.qApp.desktop().availableGeometry()))
def mousePressEvent(self, event):
QtGui.qApp.quit()
app = QtGui.QApplication(sys.argv)
mywindow = mymainwindow()
mywindow.show()
app.exec_()
