How to call function when space key is pressed inside the lineEdit

I want to call a function that checks words count in a lineEdit whenever I press space key inside the lineEdit. But how can I do that. After executing the python file press 'Start Game' to go to the lineEdit. Thanks!
Here's my code:
from PyQt5.QtWidgets import QMainWindow, QApplication, QLabel, QLineEdit, QPushButton, QTextBrowser, QStackedWidget, QWidget, QLCDNumber, QComboBox
from PyQt5 import uic
import sys
from PyQt5.QtGui import QKeyEvent
from PyQt5.QtCore import QThread, pyqtSignal, Qt
import random
class UI(QMainWindow):
def __init__(self):
super(UI, self).__init__()
# Load the ui file
uic.loadUi("Typing_test_UI.ui", self)
# Define our widgets
self.textBrowser = self.findChild(QTextBrowser, "textBrowser")
self.lineEdit = self.findChild(QLineEdit, "lineEdit")
self.counter = self.findChild(QLCDNumber, "counter")
self.startBtn = self.findChild(QPushButton, "startBtn")
self.timeCombo = self.findChild(QComboBox, "timeCombo")
self.difficultyCombo = self.findChild(QComboBox, "difficultyCombo")
self.stackedWidget = self.findChild(QStackedWidget, "stackedWidget")
self.startPage = self.findChild(QWidget, "startPage")
self.gamePage = self.findChild(QWidget, "gamePage")
self.scorePage = self.findChild(QWidget, "scorePage")
self.highScoreLabel = self.findChild(QLabel, "highScoreLabel")
self.scoreLabel = self.findChild(QLabel, "scoreLabel")
self.retryBtn = self.findChild(QPushButton, "retryBtn")
self.space_count = 0
self.startBtn.clicked.connect(self.start_game)
self.retryBtn.clicked.connect(self.goto_home_page)
# Show the app
self.show()
def start_game(self):
self.stackedWidget.setCurrentWidget(self.gamePage)
self.textBrowser.clear()
with open("Typing_sentences.txt", "r") as f:
all_texts = f.readlines()
lines_of_text = len(all_texts)
self.textBrowser.append(all_texts[random.randint(0, lines_of_text-1)])
def goto_home_page(self):
self.stackedWidget.setCurrentWidget(self.startPage)
app = QApplication(sys.argv)
UIWindow = UI()
app.exec_()
The sentences for a function in my code:
He found himself sitting at his computer, typing whatever came to mind. He was on a website entitled 10 fast fingers. This site tested how fast you were at typing. So he typed. He was currently typing about himself typing, which is odd in a way. He was now describing about how he was typing about himself typing.
The Internet is the global system of interconnected computer networks that uses the Internet protocol suite to communicate between networks and devices. It is a network of networks that consists of private, public, academic, business, and government networks of local to global scope, linked by a broad array of electronic, wireless, and optical networking technologies. The Internet carries a vast range of information resources and services, such as the inter-linked hypertext documents and applications of the World Wide Web (WWW), electronic mail, telephony, and file sharing.

Here is an example of installing an Event Filter on the QLineEdit as suggested. See the inline comments for details and explanation.
...
class UI(QMainWindow):
def __init__(self):
super(UI, self).__init__()
# Load the ui file
uic.loadUi("Typing_test_UI.ui", self)
# Define our widgets
...
...
self.spaceFilter = SpaceFilter(parent=self) # init filter
self.spaceFilter.spacePressed.connect(self.my_function) # connect to the signal
self.lineEdit.installEventFilter(self.spaceFilter) # install on lineedit
self.space_count = 0
self.startBtn.clicked.connect(self.start_game)
self.retryBtn.clicked.connect(self.goto_home_page)
# Show the app
self.show()
def my_function(self): # custom function that runs when space bar is
for i in range(5): # pressed while typing in the line edit
for i in range(1000):
print(str(i), end="\r")
def start_game(self):
self.stackedWidget.setCurrentWidget(self.gamePage)
self.textBrowser.clear()
with open("list1.txt", "r") as f:
all_texts = f.readlines()
lines_of_text = len(all_texts)
self.textBrowser.append(all_texts[random.randint(0, lines_of_text-1)])
def goto_home_page(self):
self.stackedWidget.setCurrentWidget(self.startPage)
class SpaceFilter(QObject): # the event filter object
spacePressed = pyqtSignal() # the signal emited when space bar detected
def eventFilter(self, widget, event):
if event.type() == QEvent.KeyPress: # listen for key press events
if event.key() == Qt.Key.Key_Space: # if the key is the space bar

I want to add a widget dynamically from my Python script to the main layout ('layout'):
app = QApplication(sys.argv)
f = MyWindow()
sys.exit(app.exec_())
class MyWindow(QWidget):
def __init__(self):
super(MyWindow, self).__init__(None)
ui_file = QtCore.QFile("./myui.ui")
ui_file.open(QtCore.QFile.ReadOnly)
loader = QtUiTools.QUiLoader()
self.window = loader.load(ui_file)
ui_file.close()
self.layout.addWidget(QLabel('Stuff'))
self.window.show()
However, I get the following error
self.layout.addWidget(QLabel('Stuff'))
AttributeError: 'builtin_function_or_method' object has no attribute 'addWidget'
I don't understand why self.layout doesn't have the property addWidget. I thought self.layout would have a reference to a QVBoxLayout object?

You have several errors:
The widget loaded from the .ui is not the MyWindow, on the other hand in PySide2 it is not possible to load a .ui to a widget class implemented by python (in PyQt5 if possible via uic.loadUi()) so the class should handle the widget.
On the other hand, do not use variable names that may conflict with the names of the methods, for example the QWidget class has a layout method so it is not recommended that you have an attribute with that name, a possible solution is to use findChild to get the layout:
import sys
from PySide2.QtCore import QObject, QFile
from PySide2.QtWidgets import QApplication, QLabel, QVBoxLayout, QWidget
from PySide2.QtUiTools import QUiLoader
class Manager(QObject):
def __init__(self):
super(Manager, self).__init__(None)
ui_file = QFile("./myui.ui")
ui_file.open(QFile.ReadOnly)
loader = QUiLoader()
self.window = loader.load(ui_file)
ui_file.close()
lay = self.window.findChild(QVBoxLayout, "layout")
lay.addWidget(QLabel("Stuff"))
self.window.show()
if __name__ == "__main__":
app = QApplication(sys.argv)
f = Manager()
sys.exit(app.exec_())
Another possible solution is to change the name of the layout to for example vlayout: <layout class="QVBoxLayout" name="vlayout">
import sys
from PySide2.QtCore import QObject, QFile
from PySide2.QtWidgets import QApplication, QLabel, QWidget
from PySide2.QtUiTools import QUiLoader
class Manager(QObject):
def __init__(self):
super(Manager, self).__init__(None)
ui_file = QFile("./myui.ui")
ui_file.open(QFile.ReadOnly)
loader = QUiLoader()
self.window = loader.load(ui_file)
ui_file.close()
self.window.vlayout.addWidget(QLabel("Stuff"))
self.window.show()
if __name__ == "__main__":
app = QApplication(sys.argv)
f = Manager()
sys.exit(app.exec_())

How to access a button from Tab Widget in PyQt5

I have made a Tab Widget Window in my Main Window using Qt-Designer and I am trying to access a button in my 1st Tab.
This is my code.
import sys
from PyQt5 import QtCore, QtGui,uic,QtWidgets
class AddWindow(QtWidgets.QDialog):
def __init__(self):
super(AddWindow,self).__init__()
uic.loadUi('AddWindow.ui',self)
class MyApp(QtWidgets.QMainWindow):
def __init__(self):
super(MyApp,self).__init__()
uic.loadUi('MainWindow.ui',self)
self.AddButton.clicked.connect(self.Addwindow)
def printW(self):
print("hello")
def Addwindow(self):
addwindow=AddWindow()
addwindow.exec_()
if __name__ == "__main__":
app = QtWidgets.QApplication(sys.argv)
window = MyApp()
window.show()
sys.exit(app.exec_())
I just want to have my button on 1st tab (named print) connected with function printW So I can display something on screen.

I have tried creating a class and accessing button but could not do it.

How to get signal of button from QListWidgetItem, that was set using setItemWidget? How to delete QListWidgetItem without blank space?

Introduction:
I have got listWidget, that contains QListWidgetItem(s). On each of them I have got 3 buttons. 'Close' has to destroy QListWidgetItemcompletely, postpone has to close temporary, but will emerge on the next timeout of timer. So I have to save it to list or hide temporary.
UI part created in Designer.
Image:
Already tried:
I've tried #pyqtSlot(QListWidgetItem) def on_itemClicked(self, item), but the signal does NOT emit on clicking on buttons - only on clicking on the item itself. Even if you click on item, it will close, but it still has the 'frame of widget' of the QListWidgetItem, and it is still accessible by clicking. So it does NOT close the QListWidgetItem, but inst_pop_up.
Image:
I've found the solution, using eventFilter, but didn't figured out how to set it properly in Python.
I have tried to close the onePopUp from it's button 'Close' (uncomment here to see: self.pushButton_close.clicked.connect(self.close)), but it lefts 'frame of widget' as well.
The popupMain instance is initiated in init of MainWindow class:
self.pop_up_main = popupMain()
The Timer called in the MainWindow class:
self.pop_up_main.slot_add_new()
self.pop_up_main.show()
The problem is in onePopUp or popupMain

What I have to do?
I have to distinguish what button sent the signal.
close (button 'Close')
take form QListWidget temporary('Postpone')
call method from another class MainWindow.add_record(#with the period of time on this widgetItem) (button 'Add record')
Also I have to do the postponing (button 'Postpone all') and closing to all (button 'Closing all') on popupMain buttons. But I even don't know hot to do on one item...
P.S. I have surfed everywhere, but can't figure out how to do it!

I have figured out how to do it. I've used list of tuples, that connected itemlistWidget and one_pop_up instance. I also used basic takeItem. It works perfectly.
I use hide in order to postpone the item.

Pyside2 QAction triggers once automatically but not when user clicks the menu

I've created a simple GUI using qt designer and imported it into my python project. The main window comes up, and the menus/buttons are responsive, but I cannot manage to connect my QActions to custom functions (I did it for buttons though, and it works). The weird thing is that my custom function (on_action_clicked) is called once when I run the application, but not when I click on the menu items or icons of the toolbar (I tried connecting both). Below are the test codes. Am I missing something?

You have 2 errors:
on_btn_clicked is a method of the class so it must have as the first parameter the instance, that is, self.
the connection is with the name of the function without evaluating, in your case the slot on_action_clicked you are evaluating it, so you are getting it printed at the beginning, for it there are 2 possible solutions: use partial or use a lambda function.
self.btn = self.window.findChild(QPushButton, 'pushButton')
self.btn.clicked.connect(self.on_btn_clicked)
self.action_save = self.window.findChild(QAction, 'action_save_state')
self.action_save.triggered.connect(partial(self.on_action_clicked, 'action clicked'))
# self.action_save.triggered.connect(lambda: self.on_action_clicked('action clicked')) # use lambda function
self.window.show()
def on_action_clicked(self, txt):
print(txt)
def on_btn_clicked(self):
print('button clicked')
