How to simply update a Table in a PyQt GUI?

I want to create the basic look of my GUI with Qt-Designer, and add the functions via coding afterwards. Maybe there is already the Problem, but let's go on further.
My GUI that i created via Qt desinger consists of a 4x4 Table and a button.
When the Button is pressed, i want to write something in the cells of the Table.
(Sure, this in particular would be possible without using Qt desinger. But for the future there iwant to creat some more difficult GUIs. And therefore the Qt designer does save quite some time for a newbie like me :) )
The GUI code is:
from PyQt5 import QtCore, QtGui, QtWidgets
class Ui_Form(object):
def setupUi(self, Form):
Form.setObjectName("Form")
Form.resize(686, 539)
self.widget = QtWidgets.QWidget(Form)
self.widget.setGeometry(QtCore.QRect(10, 60, 258, 223))
self.widget.setObjectName("widget")
self.verticalLayout = QtWidgets.QVBoxLayout(self.widget)
self.verticalLayout.setContentsMargins(0, 0, 0, 0)
self.verticalLayout.setObjectName("verticalLayout")
self.tableWidget = QtWidgets.QTableWidget(self.widget)
self.tableWidget.setObjectName("tableWidget")
self.tableWidget.setColumnCount(4)
self.tableWidget.setRowCount(4)
item = QtWidgets.QTableWidgetItem()
self.tableWidget.setVerticalHeaderItem(0, item)
item = QtWidgets.QTableWidgetItem()
self.tableWidget.setVerticalHeaderItem(1, item)
item = QtWidgets.QTableWidgetItem()
self.tableWidget.setVerticalHeaderItem(2, item)
item = QtWidgets.QTableWidgetItem()
self.tableWidget.setVerticalHeaderItem(3, item)
item = QtWidgets.QTableWidgetItem()
self.tableWidget.setHorizontalHeaderItem(0, item)
item = QtWidgets.QTableWidgetItem()
self.tableWidget.setHorizontalHeaderItem(1, item)
item = QtWidgets.QTableWidgetItem()
self.tableWidget.setHorizontalHeaderItem(2, item)
item = QtWidgets.QTableWidgetItem()
self.tableWidget.setHorizontalHeaderItem(3, item)
self.verticalLayout.addWidget(self.tableWidget)
self.pushButton = QtWidgets.QPushButton(self.widget)
self.pushButton.setObjectName("pushButton")
self.verticalLayout.addWidget(self.pushButton)
self.pushButton.clicked.connect(say_hello)
self.retranslateUi(Form)
QtCore.QMetaObject.connectSlotsByName(Form)
def retranslateUi(self, Form):
_translate = QtCore.QCoreApplication.translate
Form.setWindowTitle(_translate("Form", "Form"))
item = self.tableWidget.verticalHeaderItem(0)
item.setText(_translate("Form", "1"))
item = self.tableWidget.verticalHeaderItem(1)
item.setText(_translate("Form", "2"))
item = self.tableWidget.verticalHeaderItem(2)
item.setText(_translate("Form", "3"))
item = self.tableWidget.verticalHeaderItem(3)
item.setText(_translate("Form", "4"))
item = self.tableWidget.horizontalHeaderItem(0)
item.setText(_translate("Form", "A"))
item = self.tableWidget.horizontalHeaderItem(1)
item.setText(_translate("Form", "B"))
item = self.tableWidget.horizontalHeaderItem(2)
item.setText(_translate("Form", "C"))
item = self.tableWidget.horizontalHeaderItem(3)
item.setText(_translate("Form", "D"))
testitem=QtWidgets.QTableWidgetItem()
self.tableWidget.setItem(1, 0, testitem)
self.pushButton.setText(_translate("Form", "PushButton"))
self.pushButton.clicked.connect(say_hello(testitem))
def say_hello(testitem):
print("Hello you!")
testitem.setText("Hi")
the GUI gets called from another file like that:
from PyQt5 import QtCore, QtGui, QtWidgets
from PyQt5.QtWidgets import QApplication
import sys
import GUI_PyQtn
class ExampleApp(QtWidgets.QWidget, GUI_PyQtn.Ui_Form):
def __init__(self, parent=None):
super(ExampleApp, self).__init__(parent)
self.setupUi(self)
def main():
app = QApplication(sys.argv)
form = ExampleApp()
form.show()
app.exec_()
if __name__ == '__main__':
main()
My thoughts on my approach were, creating the Cell object and pass it to the function "say_hello". If the function would be inside the Ui_Form Class, it acutally called it not even once.

I believe you can get what you're looking for with the following tweaks.
Declare testitem with self in class Ui_Form
Declare say_hello in class Ui_Form
Pass testitem in say_hello by lambda
No use click.connect() in retranslateUi
that's it

How to check if a checkbox is checked in a qtablewidget?

I'm setting a filtering tool in Python 3.7 and I'm using pyqt5. I've created a qtablewidget to store the filters and their complementaries chosen by the user. I'd like to allow the user to combine filters over a data so I added grouped checkboxes in each row to select wanted filters.
Which commands should I use to loop over my qtable to get which checkbox is selected please?
def bindApply(self):
checked_list = []
for i in range(self.tableWidget.rowCount()):
#print(self.tableWidget.rowCount())
if self.tableWidget.item(i, 1).checkState() == QtCore.Qt.Checked:
checked_list.append([i,1])
elif self.tableWidget.item(i, 2).checkState() == QtCore.Qt.Checked:
checked_list.append([i,2])
else:
pass
return(checked_list)
I expect a list containing the indexes of selected rows and columns but my function returns nothing.
Here is a reproducible example:
from PyQt5 import QtCore, QtGui, QtWidgets
class Ui_MainWindow(object):
def setupUi(self, MainWindow):
MainWindow.setObjectName("MainWindow")
MainWindow.resize(550, 350)
MainWindow.setMinimumSize(QtCore.QSize(550, 350))
MainWindow.setMaximumSize(QtCore.QSize(550, 350))
self.centralwidget = QtWidgets.QWidget(MainWindow)
self.centralwidget.setObjectName("centralwidget")
self.tableWidget = QtWidgets.QTableWidget(self.centralwidget)
self.tableWidget.setGeometry(QtCore.QRect(20, 20, 500, 200))
self.tableWidget.setObjectName("tableWidget")
self.tableWidget.setColumnCount(3)
self.tableWidget.setRowCount(0)
item = QtWidgets.QTableWidgetItem()
self.tableWidget.setHorizontalHeaderItem(0, item)
item = QtWidgets.QTableWidgetItem()
self.tableWidget.setHorizontalHeaderItem(1, item)
item = QtWidgets.QTableWidgetItem()
self.tableWidget.setHorizontalHeaderItem(2, item)
self.pushButton_Save = QtWidgets.QPushButton(self.centralwidget)
self.pushButton_Save.setGeometry(QtCore.QRect(120, 250, 100, 50))
self.pushButton_Save.setMinimumSize(QtCore.QSize(100, 50))
self.pushButton_Save.setMaximumSize(QtCore.QSize(100, 50))
self.pushButton_Save.setObjectName("pushButton_Save")
self.pushButton_Apply = QtWidgets.QPushButton(self.centralwidget)
self.pushButton_Apply.setGeometry(QtCore.QRect(260, 250, 100, 50))
self.pushButton_Apply.setMinimumSize(QtCore.QSize(100, 50))
self.pushButton_Apply.setMaximumSize(QtCore.QSize(100, 50))
self.pushButton_Apply.setObjectName("pushButton_Apply")
MainWindow.setCentralWidget(self.centralwidget)
self.menubar = QtWidgets.QMenuBar(MainWindow)
self.menubar.setGeometry(QtCore.QRect(0, 0, 550, 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"))
item = self.tableWidget.horizontalHeaderItem(0)
item.setText(_translate("MainWindow", "Name"))
item = self.tableWidget.horizontalHeaderItem(1)
item.setText(_translate("MainWindow", "Filter"))
item = self.tableWidget.horizontalHeaderItem(2)
item.setText(_translate("MainWindow", "complementary"))
self.pushButton_Save.setText(_translate("MainWindow", "Save"))
self.pushButton_Apply.setText(_translate("MainWindow", "Apply"))
#============================ BINDING ===============================
self.pushButton_Save.clicked.connect(self.bindSave)
self.pushButton_Apply.clicked.connect(self.bindApply)
def bindSave(self):
numRows = self.tableWidget.rowCount()
self.tableWidget.insertRow(numRows)
groupButton = QtWidgets.QButtonGroup(self.tableWidget)
groupButton.setExclusive(True)
it1 = QtWidgets.QTableWidgetItem("filter "+str(numRows))
self.tableWidget.setItem(numRows, 0, it1)
ch_bx1 = QtWidgets.QCheckBox()
groupButton.addButton(ch_bx1)
self.tableWidget.setCellWidget(numRows, 1, ch_bx1)
ch_bx2 = QtWidgets.QCheckBox()
groupButton.addButton(ch_bx2)
self.tableWidget.setCellWidget(numRows, 2, ch_bx2)
def bindApply(self):
checked_list = []
for i in range(self.tableWidget.rowCount()):
#print(self.tableWidget.rowCount())
if self.tableWidget.item(i, 1).checkState() == QtCore.Qt.Checked:
checked_list.append([i,1])
elif self.tableWidget.item(i, 2).checkState() == QtCore.Qt.Checked:
checked_list.append([i,2])
else:
pass
print(checked_list)
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()

You should check the state of the check boxes assigned to the cells, not the state of the item associated with the cell, i.e.
def bindApply(self):
checked_list = []
for i in range(self.tableWidget.rowCount()):
#print(self.tableWidget.rowCount())
if self.tableWidget.cellWidget(i, 1).isChecked():
checked_list.append([i,1])
elif self.tableWidget.cellWidget(i, 2).isChecked():
checked_list.append([i,2])
else:
pass
print(checked_list)

Is there a way to change a label of one window from another window?

I've got some code that checks which checkboxes a user clicks. Those are then put into an array (aylm). Once the user clicks the book button, a small confirmation window pops up which says are you sure you want to book these rooms. In this confirmation window, I would like the label to say are you sure you want to book (aylm)? so that all the rooms and times selected can be seen by the user. I am not sure how to go about this since I'm using one main window which connects all the smaller windows together, which you can see below in the code.
class Ui_DialogBook(QtWidgets.QDialog, Ui_DialogBook):
def __init__(self, parent=None):
super(Ui_DialogBook, self).__init__(parent)

self.dialogBook = Ui_DialogBook()
self.book_Button.clicked.connect(self.dialogBook.show)
self.book_Button.clicked.connect(self.book_clicked)
#QtCore.pyqtSlot()
def book_clicked(self):
items = []
for i in range(self.tableWidget.rowCount()):
for j in range(self.tableWidget.columnCount()):
item = self.tableWidget.item(i, j)
if item.checkState() == QtCore.Qt.Checked:
items.append(item)
for it in items:
r = it.row()
c = it.column()
v, h = self.tableWidget.horizontalHeaderItem(c).text(), self.tableWidget.verticalHeaderItem(r).text()
self._checked_items.append([h, v])
aylm = (self.checked_items())
aylm_len = len(aylm)
for nm in range (0, aylm_len):
print (aylm[nm])
def checked_items(self):
return self._checked_items
