How to load a path in QtVideoWigdet - python

I have a question in pyqt5. I want to make a Videoplayer. now I'm stuck that how can I gave them complete path it not to click on the button and go to path and select the video I just want that it this one file path. Please have a look to my code. I making this for both raspberry pi and window
from PyQt5 import QtCore, QtGui, QtWidgets
class Ui_VideoWindow(object):
def setupUi(self, MainWindow):
MainWindow.setObjectName("MainWindow")
MainWindow.resize(733, 505)
self.centralwidget = QtWidgets.QWidget(MainWindow)
self.centralwidget.setObjectName("centralwidget")
self.Video_Widget = QVideoWidget(self.centralwidget)
self.Video_Widget.setGeometry(QtCore.QRect(0, 0, 711, 361))
self.Video_Widget.setObjectName("Video_Widget")
self.horizontalScrollBar = QtWidgets.QScrollBar(self.centralwidget)
self.horizontalScrollBar.setGeometry(QtCore.QRect(0, 380, 721, 16))
self.horizontalScrollBar.setOrientation(QtCore.Qt.Horizontal)
self.horizontalScrollBar.setObjectName("horizontalScrollBar")
self.play = QtWidgets.QPushButton(self.centralwidget)
self.play.setGeometry(QtCore.QRect(10, 410, 75, 23))
self.play.setObjectName("play")
self.select = QtWidgets.QPushButton(self.centralwidget)
self.select.setGeometry(QtCore.QRect(550, 410, 75, 23))

from PyQt5.QtMultimediaWidgets import QVideoWidget
if __name__ == "__main__":
import sys
app = QtWidgets.QApplication(sys.argv)
MainWindow = QtWidgets.QMainWindow()
ui = Ui_VideoWindow()
ui.setupUi(MainWindow)
MainWindow.show()
sys.exit(app.exec_())
I used this code too which is present in official documentation.
def load_video(self):
player = QMediaPlayer()
playlist = QMediaPlaylist(player)
playlist.addMedia(QUrl('F:/Fun/Songs/12.mp4'))
player.setVideoOutput(self.Video_Widget)
self.Video_Widget.show()
playlist.setCurrentIndex(1)
player.play()
while using this code which is in official documentation. this error occurred.


As the error and the docs point out, a QMediaContent must be passed to the addMedia method. To build a QMediaContent you can use a QUrl:

self.Video_Widget.setObjectName("Video_Widget")
self.horizontalScrollBar = QtWidgets.QScrollBar(self.centralwidget)
self.horizontalScrollBar.setGeometry(QtCore.QRect(0, 380, 721, 16))
self.horizontalScrollBar.setOrientation(QtCore.Qt.Horizontal)

self.play.setText(_translate("MainWindow", "play"))
self.select.setText(_translate("MainWindow", "Select"))

how to display the text in a textbox of different function of the same class in python

I am trying to get the date from a calendar widget to get printed into a textbox. The calendar widget and the textbox are in the same class but the print function is in a different function. all in the same class.
here is the code:
from PyQt5 import QtCore, QtGui, QtWidgets
import calendar
I have the printDate function to print the date
class Ui_Calendar(object):
def printDate(self, qDate):
date =('{0}-{1}-{2}'.format(qDate.month(), qDate.day(), qDate.year()))
self.setupUi.textedit.setText(date)
Here in this function i have the calendar widget and the textbox:
def setupUi(self, MainWindow):
calendar widget:
self.calendarWidget = QtWidgets.QCalendarWidget(self.centralwidget)
self.calendarWidget.setGeometry(QtCore.QRect(0, 0, 392, 236))
self.calendarWidget.setObjectName("calendarWidget")
self.calendarWidget.clicked.connect(self.printDate)
textbox:
self.textedit = QtWidgets.QLineEdit(self.centralwidget)
self.textedit.setGeometry(QtCore.QRect(20,245,80,30))
self.textedit.setObjectName("textedit")
I get the calendar widget to open when button clicked. I also can get the date printed on python shell but cannot the date on the textbox. As soon as i click the date on the calendar widget the program closes itself. i dont get any error msg.
I am new to programming and just started learning. Please help me
here is my whole code:
from PyQt5 import QtCore, QtGui, QtWidgets
class Ui_Calendar(object):
def printDate(self, qDate):
date =('{0}-{1}-{2}'.format(qDate.month(), qDate.day(), qDate.year()))

How to open another window in and take user input in Pyqt5 Python

I am trying to create a GUI using pyqt5. I have one main window with pushbutton. When i click on pushbutton it should open another window which is having input form to take first name and last name. Below is my code. I am able to open another window but when i am submitting the details on opened window and clicking on Submit Details button, nothing is happening.
Please note, if i directly call Child_ui in Main_Ui then then I am able to see the output form PrintInput function but same is not happening when I converted ui files in class.
Main_ui.py:
from PyQt5 import QtCore, QtGui, QtWidgets
class Ui_MainWindow(object):
def setupUi(self, MainWindow):
MainWindow.setObjectName("MainWindow")
MainWindow.resize(299, 148)
self.centralwidget = QtWidgets.QWidget(MainWindow)

self.pushButton = QtWidgets.QPushButton(self.centralwidget)
self.pushButton.setGeometry(QtCore.QRect(90, 70, 75, 23))
self.pushButton.setObjectName("pushButton")
MainWindow.setCentralWidget(self.centralwidget)
self.retranslateUi(MainWindow)
QtCore.QMetaObject.connectSlotsByName(MainWindow)

_translate = QtCore.QCoreApplication.translate
MainWindow.setWindowTitle(_translate("MainWindow", "MainWindow"))
self.pushButton.setText(_translate("MainWindow", "Register user"))
if __name__ == "__main__":

app = QtWidgets.QApplication(sys.argv)

I have converted this Qt designed file to class file:

.. yes it is working and i was also able to do it this way. I want to do it using two different file. Also I don't want to write logic in Qt designed file because if i do any change in Qt designer then whole script needs to change
Update

How to pass variable through different windows in PyQt5?

I have two windows, first window is 'FirstWindow' and second is 'Calendar'. first window has one push button (pbSelectDate) and one label (lbDate). calendar window has calendar (CalendarBox) and one push button (pbSelect).
when i click select (pbSelectDate) from first window, calendar window pops up. I select the date and press select button (pbSelect) in the calendar window. i want to print the selected date to the label (lbDate) in the first window.
thanks in advance. :)

How to refresh the Label text in my app when i click the Refresh Button?

I Want this app to refresh the 'label' data (Which is a datetime) when i click the Refresh Button.
I tried pushButton.clicked.connect(ui.setupUi(MainWindow)), but it is not working, im out of clue how to do that.
from PyQt5 import QtCore, QtGui, QtWidgets
from PyQt5.QtWidgets import *
import datetime
class Ui_MainWindow(object):
def setupUi(self, MainWindow):
MainWindow.setObjectName("MainWindow")
MainWindow.resize(200, 200)
self.centralwidget = QtWidgets.QWidget(MainWindow)
self.centralwidget.setObjectName("centralwidget")
self.label = QtWidgets.QLabel(self.centralwidget)
self.label.setGeometry(QtCore.QRect(30, 30, 121, 61))
self.label.setObjectName("label")
MainWindow.setCentralWidget(self.centralwidget)
self.statusbar = QtWidgets.QStatusBar(MainWindow)
self.statusbar.setObjectName("statusbar")
MainWindow.setStatusBar(self.statusbar)
self.retranslateUi(MainWindow)
QtCore.QMetaObject.connectSlotsByName(MainWindow)
def retranslateUi(self, MainWindow):
import datetime
dt = str(datetime.datetime.now())
_translate = QtCore.QCoreApplication.translate
MainWindow.setWindowTitle(_translate("MainWindow", "MainWindow"))
self.label.setText(_translate("MainWindow", dt))
pushButton = QtWidgets.QPushButton(self.centralwidget)
pushButton.setGeometry(QtCore.QRect(120, 150, 75, 23))
pushButton.setObjectName("pushButton")
# pushButton.clicked.connect(ui.setupUi(MainWindow))
pushButton.setText(_translate("MainWindow", "Refresh"))
if __name__ == "__main__":
import sys
app = QtWidgets.QApplication(sys.argv)
MainWindow = QtWidgets.QMainWindow()
ui = Ui_MainWindow()
ui.setupUi(MainWindow)
MainWindow.show()
sys.exit(app.exec_())
After clicking the Refresh button the time should update.

You really shouldn't re-initialize the ui for that, but just set the text for the label.
Also, since datetime.datetime.now() is "dynamic", you should use a lambda or, better, a dedicated slot.
The "simpler" solution, based on your code, is use this where you have the commented code:
pushButton.clicked.connect(lambda: self.label.setText(str(datetime.datetime.now())))
Or, sometimes better, the same thing in a specific method:
def retranslateUi(self, MainWindow):
# ...
pushButton.clicked.connect(self.setCurrentDate)
# ...
def setCurrentDate(self):
self.label.setText(str(datetime.datetime.now()))

You were there almost. Using pushButton.clicked.connect() is correct, but you don't need to recall the initUI function.
from PyQt5 import QtCore, QtGui, QtWidgets

self.centralwidget.setObjectName("centralwidget")
self.label = QtWidgets.QLabel(self.centralwidget)
self.label.setGeometry(QtCore.QRect(30, 30, 121, 61))
self.label.setObjectName("label")
MainWindow.setCentralWidget(self.centralwidget)
self.statusbar = QtWidgets.QStatusBar(MainWindow)
self.statusbar.setObjectName("statusbar")
MainWindow.setStatusBar(self.statusbar)
self.retranslateUi(MainWindow)
QtCore.QMetaObject.connectSlotsByName(MainWindow)
def retranslateUi(self, MainWindow):
dt = str(datetime.datetime.now())
_translate = QtCore.QCoreApplication.translate
MainWindow.setWindowTitle(_translate("MainWindow", "MainWindow"))
self.label.setText(_translate("MainWindow", dt))
pushButton = QtWidgets.QPushButton(self.centralwidget)
pushButton.setGeometry(QtCore.QRect(120, 150, 75, 23))
pushButton.setObjectName("pushButton")
pushButton.clicked.connect(lambda: self.update_time())
pushButton.setText(_translate("MainWindow", "Refresh"))
def update_time(self):
self.label.setText(str(datetime.datetime.now()))
if __name__ == "__main__":
import sys
app = QtWidgets.QApplication(sys.argv)
MainWindow = QtWidgets.QMainWindow()
ui = Ui_MainWindow()
ui.setupUi(MainWindow)
MainWindow.show()
sys.exit(app.exec_())
I made it in a seperate function so you can add more things to it if you want. You could also make pushButton a class member so you can check the state in update_time(). Or you could pass it as an function argument.

Pyqt5: Dialogue box disappears immediately after appearing [duplicate]

This question already has answers here:
Variable scopes in Python classes
(4 answers)
Closed 2 years ago.
I have a situation in which I want a dialogue box to appear when a button is clicked. I used Qt designer to create a main window as well as a dialogue box. By looking at some online tutorials and answers on StackOverflow I managed to write this code
from PyQt5 import QtCore, QtGui, QtWidgets
class Ui_MainWindow(object):
def setupUi(self, MainWindow):
MainWindow.setObjectName("MainWindow")
MainWindow.resize(557, 383)
self.centralwidget = QtWidgets.QWidget(MainWindow)
self.centralwidget.setObjectName("centralwidget")
self.pushButton = QtWidgets.QPushButton(self.centralwidget)
self.pushButton.setGeometry(QtCore.QRect(180, 70, 201, 81))
self.pushButton.setObjectName("pushButton")
self.pushButton.clicked.connect(self.newWindow)
MainWindow.setCentralWidget(self.centralwidget)
self.menubar = QtWidgets.QMenuBar(MainWindow)
self.menubar.setGeometry(QtCore.QRect(0, 0, 557, 21))
self.menubar.setObjectName("menubar")
MainWindow.setMenuBar(self.menubar)
self.statusbar = QtWidgets.QStatusBar(MainWindow)
self.statusbar.setObjectName("statusbar")
MainWindow.setStatusBar(self.statusbar)
self.retranslateUi(MainWindow)
QtCore.QMetaObject.connectSlotsByName(MainWindow)
def retranslateUi(self, MainWindow):
_translate = QtCore.QCoreApplication.translate
MainWindow.setWindowTitle(_translate("MainWindow", "MainWindow"))
self.pushButton.setText(_translate("MainWindow", "new window"))
def newWindow(self):
dialog = QtWidgets.QDialog()
self.myOtherWindow = Ui_Dialog()
self.myOtherWindow.setupUi(dialog)
dialog.show()
class Ui_Dialog(object):
def setupUi(self, Dialog):
Dialog.setObjectName("Dialog")
Dialog.resize(400, 300)
self.retranslateUi(Dialog)
QtCore.QMetaObject.connectSlotsByName(Dialog)
def retranslateUi(self, Dialog):
_translate = QtCore.QCoreApplication.translate
Dialog.setWindowTitle(_translate("Dialog", "Dialog"))
if __name__ == "__main__":
import sys
if not QtWidgets.QApplication.instance():
app = QtWidgets.QApplication(sys.argv)
else:
app = QtWidgets.QApplication.instance()
MainWindow = QtWidgets.QMainWindow()
ui = Ui_MainWindow()
ui.setupUi(MainWindow)
MainWindow.show()
sys.exit(app.exec_())
The problem is that when I click the pushbutton, the dialogue box appears for an instance and then disappears. What am I missing?
