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
self.spacePressed.emit() # emit the signal
return False

Extend QTableView parent widget height when window is resized

I would like to extend the height of ruleWhiteListWidget_2 if rulesWhiteListFileTBL height is increased. But as you can see in the example code below, the QTableView is overflowing its parent widget. I need the QTableView's parent and grandparent height to increase with the QTableView height, and then use the QScrollArea to scroll if the height extended the MainWindow. I played around with sizepolicy, but could not figure it out.

Your current design is has several redundant container widgets and layouts that are complicating things unnecessarily. Basically, you just want the table to expand to take up any extra height whenever the dialog is resized larger than the combined minimum heights of the table and the editor; and when the dialog is resized smaller than the combined minimum, you want a vertical scroll-bar to appear.
In order to make the solution clearer, I have reduced your design to an absolute minimum. It has only one container widget (named rulesWidget, which is the scroll-area container widget). This in turn has just one vertical layout set on it, which can be accessed by selecting the rulesWidget in the Property Editor and scrolling to the section at the bottom. If you do that, you will see that the layoutStretch has been set, which is what makes the table take up the extra space. Note also that the dialog itself must also have a layout set on it for everything to work properly:

UPDATE:
The minimum number of changes to get your original ui file to behave more or less the same as the above, are: (1) set a vertical-layout on the dialog; (2) remove the minimumSize on ruleWhiteListWidget; (3) set the layoutStretch to 1,0 on verticalLayout_44.

Unable to Resize Column Contents according to the values of the column

I have a table which is being populated by the Database (MySQL) at the backend.
I am trying to resize the Columns according to the contents of each column (as much the stretch is possible), however I can't seem to do it.
I looked it up on Stackoverflow and found that I can do it by setting the QScrollAbstractArea.sizeAdjustPolicy to AdjustToContents in the Qt Designer.
I did this but it still did not work.
I further looked it up and found different solutions. One of them was this as well but it also did not work for me,
self.ui.course_table.horizontalHeader().setSectionResizeMode(0, QtWidgets.QHeaderView.Stretch)
self.ui.course_table.horizontalHeader().setSectionResizeMode(1, QtWidgets.QHeaderView.ResizeToContents)
self.ui.course_table.horizontalHeader().setSectionResizeMode(2, QtWidgets.QHeaderView.ResizeToContents)
I have shared a picture of my current table right now and I want to expand each column according to the content I have.
As you can see, there is a lot of space that can be stretched but it is not doing it despite having enough space. Even the Column names are not fully visible and some characters are cut off
In not maximized window form, this is what I get
As for my data, it is coming from MySQL database and it is attached to Button Click (whenever I click on the "Courses" button on the side menu, it will populate the data on the table in the Courses Page)
The function that is populating the table is as follows,
def get_course_data(self):
mycursor = self.DB.cursor() # DB is an object of class
Subquery = "Select course_name, course_code, course_type from tbl_course"
mycursor.execute(Subquery)
numcols = len(mycursor.fetchall()[0])
mycursor.execute(Subquery)
numrows = len(mycursor.fetchall())
self.ui.course_table.setRowCount(numrows)
self.ui.course_table.setColumnCount(numcols+1)
mycursor.execute(Subquery)
tablerow = 0
for row in mycursor.fetchall():
tablecol = 0
layout = QHBoxLayout()
layout.setContentsMargins(0, 0, 0, 0)
layout.setSpacing(0)
delete_button = QPushButton()
icon_delete = QIcon()
icon_delete.addFile(u":/icons/icons/Delete-button.png", QSize(), QIcon.Normal, QIcon.Off)
delete_button.setIcon(icon_delete)
layout.addWidget(delete_button)
edit_button = QPushButton()
index = PySide2.QtCore.QPersistentModelIndex(self.ui.course_table.model().index(tablerow, tablecol))
edit_button.clicked.connect(lambda *args, index=index: self.on_course_edit_click())
icon_edit = QIcon()
icon_edit.addFile(u":/icons/icons/edit-button.png", QSize(), QIcon.Normal, QIcon.Off)
edit_button.setIcon(icon_edit)
layout.addWidget(edit_button)
cellWidget = QWidget()
cellWidget.setLayout(layout)
self.ui.course_table.setCellWidget(tablerow, 3, cellWidget)
while tablecol < numcols:
self.ui.course_table.setItem(tablerow, tablecol, PySide2.QtWidgets.QTableWidgetItem(str(row[tablecol])))
tablecol += 1
tablerow += 1
self.ui.course_table.horizontalHeader().setSectionResizeMode(0, QtWidgets.QHeaderView.Stretch)
self.ui.course_table.horizontalHeader().setSectionResizeMode(1, QtWidgets.QHeaderView.ResizeToContents)
self.ui.course_table.horizontalHeader().setSectionResizeMode(2, QtWidgets.QHeaderView.ResizeToContents)
The layout of this page of mine is as follows, (it basically has three frames who are in horizontal layout and the third frame contains the QTableWidget. The third frame's sizePolicy is set to Expanding so that it covers the whole main body while the two other performs are aligned to the top of the main body)
The .ui file (for only the course widget) is as follows

How to set Justify-Alignment for check boxes?

I have placed some QCheckBox in horizontal layout (or in grid layout).
The desired output is something like below (to get this output I have added some layout spacing, but it's not very precision):
I have also tried using setAlignment(Qt.AlignCenter) or setAlignment(Qt.AlignJustify), neither is working rightly

A possible solution is to set the horizontal policy to QSizePolicy::Maximum in the QCheckboxes, and place spacers between them:

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.
